Stromer ST2 Launch Party in Brooklyn, NY

Everybody in the electric bike community has been buzzing about the launch of the Stromer ST2 – the most aggressive electric bike ever put in to production.

Last Saturday, on March 21st, Stromed launched the bicycle in a warehouse in Brooklyn, and NYCeWheels was there to cover it.

Check out some photos from the event:

NYC Snow Biking in a Blizzard

Moonlander BionX Snow

The Moonlander has always been one of my favorite bikes. The massive tires, the ultra-lightweight frame, the cushy ride. I even wrote a review about how much I loved the Moonlander with BionX in October. I fell in love with this bike before I had the opportunity to really test the Moonlander – like a blizzard in NYC.

Check out my video review of the Moonlander with BionX to see how this bike held up.

Stromer E-bike / Go Anywhere with Power

As E-bikes get nicer and nicer, people start to notice. Climb aboard this electric-assist bike and there are many things that will get your attention. Lots of power and stopping ability are high on the list. Easy to use controls fit right in. Add some good looks and the all-terrain capabilities, and you’ve got the Stromer E-bike.

Even though these are on the menu at NYCeWheels, I rode one here on the west coast. All the hype that has been going around made my expectations high. After the first block, I could see that no one was just blowing hot air about this bike. Very nicely done, this E-bike delivers the goods. I enjoyed my ride and wanted more.

Looking more like a mountain bike that a street cruiser, the Stromer eBike is at home in both venues. Outfitted with some dual-purpose tires, I am sure you could go with either extreme and be happy. The plush front suspension has a lock-out feature, and the saddle is speced to please. With some nice drive train parts, it shifted and rode well.

The control system is done nicely. Using a high-tech load sensor on the drop-out (similar to the Gepida), it has a very responsive pedelec feel. With three levels of sensitivity at your fingertips, you can tailor the power assist to match your riding style. And unlike the European E-bikes, a throttle is here to allow you to power-up when you’re not pedaling.

It uses a half throttle, which is my preference. The power is smooth, silent, and quite noticeable. The computer that controls it all works fast, adding to the great feel the Stromer has. It gives you the juice to climb steep hills with minimum effort on your part. I should know, as I climbed the steepest one in town with a smile. Coming back down was a breeze too. The disc brakes work well.

It comes in four men’s frame sizes and two for the low-framed bike. Three different colors can be had. The frame is quite beefy, and has a spot where the battery fits in to make for a sleek and sassy look. If the brushless hub motor wasn’t visible, many people would never suspect it’s an E-bike. During the ride, I got the feeling that I could tackle any obstacle and keep going.

Speaking of going, the range of this bike should be very far. The large 37 volt lithium battery, combined with an efficient control system, can work together for some long rides. I didn’t get the chance to test the range, but my experience with similar set-ups tells me it should be doable.

The specs say up to 45 miles. At the low pedelec setting and on near level ground, I think it would make it. Under normal conditions, expect 20-25, which is still a long way.
Yes, it’s true that the Stromers’ price is on the high side. Quality doesn’t come cheap. I would suspect that it will be the second E-bike for many of the people you see riding one. You know, a person who has enjoyed and loved their first one, but is ready for the next level. But if you want an aggressive and powerful bike, jump right in. I can’t see anyone being disappointed on this electric-motored bike.

If you are close to NYCeWheels, by all means stop by for a ride. You can feel the smooth, quality features for yourself. Even if you can’t try it first, you might already know that this is the E-bike for you. A Stromer bike could make a definite change in your transportation world. I am sure you have read and seen many things that are drawing towards a bike like this. Park the car, skip the bus, and feel the open air. E-bikes just put a smile on your face while you save money, and trim your body. They will also change your attitude, for the better.

Advantages of the E-bike

Many of us have, at one time or other, asked ourselves, “I’m in shape, I exercise, why would I want to buy an electric bike? In fact, there are many reasons why an e-bike might be the best purchase you could make.

E-bikes are cheap and green

Like regular bikes, Electric bikes offer a cheap environmentally friendly way to commute. Instead of paying for gas, save the change, and help reduce your carbon footprint.


E-bikes make long distance commuting possible

E-bikes also open up many possibilities for the everyday commuter. With an E-bike like the Kettler Twin, you can go very long distances without depleting your energy. For someone who has always lived in Manhattan, but moved outside the city for a little more room, an electric bike might be the only way to make the 20 mile a day commute without paying gas prices or exhausting yourself pedaling long miles.

Electric bikes give you choices

An E-bike gives you more options as a biker. Many electric bikes, such as the Stromer Electric Bike, allow you to choose how much electric assistance you receive at any given time. If you’re cruising long distance, you might choose to have light assistance, saving the battery and increasing your range; if you’re heading up a hill, crank up the assistance to full for a fast efficient climb; or if want to get a little more exercise, you can switch the motor off, and even add resistance to recharge the battery.

Electric bikes make it easy to ride together

Often couples or riding partners have different fitness levels and stamina. How many times have you tried to plan that perfect bike trip with your family, only to be met with a slew of hills and sullen complaints? With an electric bike you could take your dad out on your favorite 20 mile path without being worried that he’s going to struggle to keep up.


E-bike= great times

Last, and maybe most important, E-bikes are just amazingly fun. There’s just something great about blasting along a flat, pushing 20 and passing hardcore road-bikers on your left and right. Whether you are a pro, or your just trying out bikes for the first time, riding an Electric bike is, without a doubt, a pretty great way to spend an afternoon.

buying an eBike – doing the research first

I (Joe) recently became interested in ebikes, have done some extensive research, and finally bought a commercial model on which I’ve put a few hundred miles in the last two weeks. I’ll provide a review of that bike shortly, but first wanted to collect some more general thoughts on ebikes which I’ve consolidated from my research, personal experience, and a good dose of engineering basics. I’m certain almost everything I discuss here has been stated better and more thoughtfully elsewhere, so please forgive my repetition and perhaps naive thoughts. I will say, I think I would have found this type of write-up helpful to me early-on, and hope this discussion may help other potential new ebike riders as well.

So, if you’re like me, the idea of an ebike is appealing. Gas prices are up, “green” transportation is in, and bike commuting has a number of distinct advantages over other forms. Personally, I’ve been a bike commuter for about 3 years now. My regular job is outside Santa Fe, NM, and I have a decent enough means to bike commute about 10 months out of the year, with snow and weather leaving a few weeks for the car. Of course, bike commuting entails other compromises, such as the difficulty in accommodating “business” clothes, “helmet” hair, inclement weather, and of course, safety. As experienced bike commuters known, there’s pretty good solutions to most of these issues, with equipment, planning, and setting realistic expectations all playing a role.

eBike, bicycle with electric assist motor

The appeal of an ebike to me is the ability to commute a bit farther, to eliminate the more difficult portions of my commute and arrive “sweat free”, to perhaps save a bit of time, and to allow farther in-day trips from my main work site to various other locales at my employer (which is spread over 43 square miles, I often need to travel to more remote sites where I work). As important, is what an ebike for me wasn’t. It’s not a replacement for a motorcycle. I didn’t want to travel long distances just punching a throttle. I wanted this to be mostly bike with the added benefit of power assist. Taking my bike on public transport, into my office via an elevator, parking with other bikes, etc. are all important.

So, how does this lengthy preamble relate to choosing an ebike? If you read the ebike forums, there’s a near-obsession with specific characteristics of these bikes such as top speed, weight, and perhaps most prominent, range and battery capacity. Naturally, everyone has a list of requirements and desires that they want their bike to meet. At the top of many lists are reliability, range, light weight, top speed, and of course, low cost and maintenance. This wish list quickly runs head-on into the reality of engineering and design. You quickly discover there’s no one perfect bike that does it all. Some of the better ebike retailers start with a very good list of questions to help determine a customers desires. Given this, they can direct you toward a particular system, design, or model.

I stated many of my desires above. Considering my criteria, it was clear that a pedal-assist application is the way to go. The engineering analysis of pedal assist is itself a fascinating topic. In order to appreciate the benefits of pedal-assist, and of ebikes more generally, I found it enormously helpful to discuss and understand some specific characteristics of the most important motor on the ebike. No, not the electric hub, but YOU. Your power output and contribution to propulsion, and understanding the highly non-linear nature of that power output, is actually the key to understanding why pedal-assist is such an attractive option. So, if you’ll forgive my diversion here, I’d like to discuss a few elements of human power output.

You and I consume energy just by living. A resting person weighing 150 pounds has a metabolic rate of about 70 Watts (W). Light activity such as walking and just doing your day to day thing without exertion bumps this up to about 100-125 W. That’s just how our bodies have evolved in our environment. As you start to exert yourself, you spend more energy. This relationship is highly nonlinear. A moderate workout, in which you get your heart rate up and sweat quite a bit, has a total power output of about 200 to 250 W. Tour de France riders with years of special training, nutrition, and conditioning can sustain power outputs of 400 to 500 W for hours on end. You and I, not so much. Over about 300 W, and we’ll tire pretty quickly. So, 100 W is literally “no sweat”, while that next 100 W isn’t nearly as easy. It’s this nonlinear relation between exertion and power output that makes a pedal-assist ebike so attractive.

The goal is to transmit efficient power into the bike. As a rider, you can contribute a nice, healthy 50-100 W (on top of your metabolic 70-90 W) for a very long time, and you won’t notice this as much exertion. These should be the “first Watts” that the bike sees. It just so happens, that pedaling a bike on level ground in no wind requires roughly 100 W to sustain a speed of roughly 25 km/hr. This is the level that most folks would see as “easy” without much exertion. Of course, add a headwind, or hills, or a higher speed, and things quickly turn against you. Further, starts and stops require quite a bit of extra energy, too. Nearly every rider knows this intuitively without the engineering degree, and this helps to explain why bikers don’t particularly like to stop if they can help it, safety be damned.

Now, let’s consider a throttle-only, no pedal ebike versus a pedal assist. If your goal is to get long range with much less exertion on your part, the numbers quickly tell the story of why pedal-assist is so attractive. Remember that 100W figure for sustained 25 km/hr on level ground? At the theoretical limit, a throttle-only vehicle would last about 3 hours with a typical 36V, 10 Amp-hr battery pack (360 W-Hr), whereas a pedal-assist wouldn’t be contributing at all, and would have infinite range, since the rider is providing that first 100 W. Now, this is all theoretical. In practice, hills, starts/stops, the efficiency of your bike and motor, etc. quickly degrade these numbers. More typically, that throttle-only bike with a 360 W-hr battery may have a range of 30-40 km in total. Conversely, a good pedal-assist system in practical use on level ground driven in a way so that you don’t exert can have a range on order 80-90 km or even more.

And it’s the deviations from this ideal ride where pedal assist becomes so appealing. Take hills, for example. The added power to crest that hill can be contributed by the battery, so you don’t have to exert. You’re not constantly climbing during your ride (well, for most rides that is), and the addition of power assist as the last Watts added is what provides that marvelous ability to extend range, open up a whole-new way of biking, and achieve the near-nirvana of long-range, reliability, ease, and (relatively) low cost for an ebike. (And BTW, some studies have shown that the more constant exertion of steady, light exercise may be as beneficial as other forms. Pedal assist hybrid on ebike indeed may be a have-your-cake and eat-it-too proposition when it comes to fitness.)
Ok, so the previous is basically an engineering discussion of ebike propulsion. How does it work in practice and how can you use this understanding to maximize your ebike experience? A couple of things are important right up front, namely, speed and acceleration. Most folks want more speed, its only natural. Unfortunately, things quickly turn against you as you go faster from an energy management standpoint. Top of the list is drag. Drag increases as the square of your speed. Given that most of your energy (on flat ground) goes to moving the air out of the way, this gets ugly quick. If you’re willing to go a little slower, you have the enormous payoff of greatly extending your range. From a practical standpoint, 30 km/hr or so (19 mph) feels about right to me as a nice compromise between speed and efficiency. Others will balance this differently. It just so happens that 32 km/hr is codified in US law as well. At first, I wanted that super-fast ebike that did it all. After spending some time on my current bike, I’ve come to the conclusion that a moderate speed really is best, not only for efficiency, but for safety as well.

Ditto acceleration. My ebike (Trek Valencia+ with the Bionx system) has a 27-speed drive-train which I thought was ridiculous at first, since I could easily keep this in the lowest gear, and just let the motor pull me away from stops. It turns out, this is really bad energy management practice. Hard acceleration is inefficient and sucks tons of precious amps from your battery (just look at the meter on a Bionx system). I’ve come to realize that those extra low gears on the Valencia are actually very useful. Now, I down-shift at stops most of the time, and take just a bit longer to get up to speed, with the Bionx system providing more of a gentle nudge than full-on zippiness. Of course, that zippiness is there is you want it, or when time or safety require. The payoff in backing away from jack-rabbit starts is greatly extended range.

I rode the Critical Mass ride this Friday in San Francisco on the ebike, including some substantial distance to/from the event (yes, I mentioned my job was in New Mexico; I’m spending the year in the Bay Area on another assignment). I got about 50 miles out of the Trek/Bionx system, and had a grand time. Trek worked with Bionx and changed a number of factors in the Bionx system, some of which I think are not well-understood by the ebike crowd, including a change in battery voltage and capacity.

So, I’ve written a tome as a first post. Please forgive this. My goal was to pass along some of the things I learned in my research leading up to my first ebike kit purchase. More experienced folks here will no-doubt correct errors or offer additional points, which I look forward to.

Electric bike kit

NYCeWheels just added an electric bike kit guide to their website.

They walk you through all of the important questions step by step. I wish they had it around when I first picked out my folding bike and equipped it with an electric bike kit. It'd have saved me some time during my research. The electric bike kit guide appears to be an ongoing project. I encourage all of you to look it over and see if you have any questions that aren't answered on it. The more feedback you give them, the more they'll improve and add to the electric bike kit guide, and the more useful it will be to everyone.

I always get excited by resources such as this, especially when they are dynamic and respond to the needs of the user with new updates and information. It just makes me feel like part of a community. The electric bike kit community grows more and more every day, so it's good to see resources for that community, with it in mind, that respond to the needs of the community.

E-Brompton Banter—Part 6—Spark-E—What’s in a Name?

As a member of the London Brompton Club, I get to see a lot of what is going on in this great folding bikes hometown. One of the things I’ve noticed over and over is that many of the bikes in the club have names. In fact, I have been egged on by several of my fellow members to name mine. One suggested the name ‘Sparky’.

Electric Brompton Bike

Electric Brompton Bike

Sparky the Brompton Bike?

I’m sure you can get a feel for the thought behind this name. E-Brompton, electricity, sparks. All that comes together into a fun name. Me, I’m not all that hot on naming my bikes, but the idea has merit. Some of the names for the club’s bikes are clever or have some deeper meaning I‘m not privy to.

If you are a Brompton lover too, head on to their site on Facebook for a look.
I don’t ever expect to see any sparks from this great little folding bike. The quality of the electric-assist conversion by NYCeWheels is top-notch with no worries of such things. With some of the best pieces available, from the motor down to the smallest connector, the only light coming from this baby is shooting out of the headlight I use for night riding.
The months keep rolling by and so does this awesome little E-Brompton. Of course I have wiped it down and aired-up the tires a few times. Other than that, it has been nothing but good old-fashioned fun with nary a hiccup. Although it’s boring to not have any bad news to report, riding it is anything but. It is truly a fun generator, an ’E’ ticket ride from day one.

From day one with my E-Brompton

You might remember the week I got it, it was part of the radio show I was invited to be on. They wanted to talk E-bikes and the E-Brompton was on hand to back me up. Both the radio hosts rode the E-Brompton and E-bikes were the topic of the evening. One of them even joked (not really funny) that she was going to pop it in her trunk while I was on the air. There was a lot of electrical energy that night, but no sparks.
When I gave my E-bike seminar in July, it was the first E-bike I showed the crowd. I used it as the example that E-bikes are just bikes with an added accessory. First I rode it without the battery, and then with. After my talk many people took it for a ride. For some of them it was not only their first E-bike ride, but their first exposure to a Brompton. There was plenty of excitement that night, but again, no sparks.
I took it to the opening of a new section of beach trail near Coronado. There was a big crowd that day. I can’t even remember how many people mounted up the E-Brompton and took a spin on the bikeway. Up and down the trail it went countless times. Everyone got off with the biggest smile. And tons of gawking took place every time I folded it into a little itty-bitty package. If sparks were going to fly, that would have been the day.

Traveling with the E-Brompton

Traveling with the E-Brompton

Traveling with the E-Brompton

Twice this electric-assist folder has made the trek to CicLAvia, (in the trunk of the car as LA would have been quite a ride from my place). With 100,000 people and bikes on hand, we talked to plenty of Brompton owners. Each one was pleased to see how nicely the electric conversion was done and wanted to give it a try. The power was flowing that day. Lot’s of electricity got used and not one spark was seen.
I taken it on many group rides here in town. Lots of them have been night rides. Lights blinking everywhere is always part of the scene. The E-Brompton gets its share of lights and looks at each one. It is always easy to keep up with the group using the pull of the motor when needed. The glowing sidewalls may have seemed on fire, but that was the only thing sparking on those rides.
We just got back from a great trip to Yosemite and Santa Cruz. With a pair of folding bikes in the trunk, (The E-Brompton and the Tern Link P9---both from NYCeWheels) we rode in so many places. Cruising though the trees and spectacular scenery at Yosemite was just electrifying. There is no better way to see parts of this great country than from the seat of a folding E-bike. Thank goodness there were no sparks on that week.
So I won’t be naming this E-Brompton anytime soon. If I did, then possibly naming it after a toy drum-banging bunny or a watch that keeps running after an elephant steps on it would be more appropriate. The E-Brompton from NYCeWheels just keeps rolling on the miles with no complaints. If you’ve named your Brompton, let us know what it is and why, thanks.

What‘s in a name?

Six Reasons the Stromer ST1 is the Perfect Vehicle for Cold Weather


Stromer ST1 electric bike

Unlike when I borrowed the eBrompton and the electric assist Dahon Formula from NYCeWheels, I got my hands on the Stromer ST1 as the traditional riding season was ending. The fewer the leaves on the trees, the fewer the cyclists on the roads. Seeing your breath becomes routine and eventually it gets so cold you have to wear a full face neoprene mask - the DefCon 5 of winter preparedness.

But the bike itself makes riding in winter easier than it has ever been and in just one sitting I can come up with six reasons why the Stromer ST1 is perfect for winter riding.


6. Those big tires


Stromer ST1 Electric Bicycle


As winter closes in, leaves fall, twigs snap, and missing Stupid Car Antlers show up on the road in front of you. Riding anything smaller causes a wince when you hit obstacles - no matter how small - but not with this bike.


5. It doesn’t need to warm up.


In a car, you have to hustle into the cold, sit on the cold seat, turn the cold keys and wait until spring for the engine to warm up. When I take the Stromer all I have to do is carry it outside, turn it on, and start pedaling. Bonus: no windshield to defrost and most car trips are so short the car won’t even warm up by the time you get there anyway.


4. It doesn’t have to be parked


You’ll want to bring a good lock with you for sure but the Stromer ST1 is the best vehicle for holiday shopping. I can lock it at a shop, buy gifts for my entire family, and by the time I’m done the baby excrement-green Kia will still be sitting in the parking lot with the blinker on waiting for the Suburban to JUST MOVE ALREADY!


3. In city driving, it’s almost as fast as a car


If I want to drive my car to New Canaan from Stamford, Connecticut, it takes a little over 20 minutes. Riding the Stromer ST1 I made it in just under 30 minutes. But even with falling gas prices, it’s a lot cheaper per mile and the quality of those minutes is just far better than any car. And remember: I don’t have to count the time it takes to find a place to park.


2. It’s easier to ride than a regular bike


Most of the price tag for a Stromer ST1 is for the 500 watt motor and the electric assist system. And while I always appreciated it for the speed I didn’t realize how nice it is until I rode a regular bike in cold weather. On a normal bike, you have to wear warm clothing but the exertion of climbing up a hill can make you sweat. When riding the Stromer I feel like my pace is more regular and I’m not on a temperature yo-yo all the time.


1. It’s fun and it feels good to ride


Stromer ST1 Electric Bicycle

If James Franco and the guy from ‘Knocked Up’ can’t entertain me on Christmas Day, the terrorists win. To that end, if I can’t go for a bike ride in cold weather, winter wins. Even if you shiver, even if you end up hating the landscape straight out of Cormac McCarthy’s The Road, even if you get snotsicles - riding a bike in cold weather is a victorious occasion - and it makes us yearn for the warmer days that are ahead. Hope you get to do that yearning on the seat of the ST1.

The Stromer ST1 – The First Ride


Stromer ST1 Electric Bike

If you live in a four story walk-up in Greenwich Village do not - I repeat - do not buy a Stromer ST1 under any circumstances.

I’m just throwing that out there.

Here’s the thing: I’ve already ridden and reviewed the electric assist Brompton and Dahon Formula, and these are electric assist folding bikes that brag about their weight and portability. The Stromer ST1 doesn’t fold and, at 62 pounds, is around twenty pounds heavier than either of those aforementioned NYCeWheels bikes.

The fact that it doesn’t fold was an issue out of the gate, because I couldn’t bring it with me on the train if I returned from Manhattan during Metro North peak hours. So I brought it home early one weekday afternoon and was not only able to bring it on the train easily, but I was able to see one of the new and seldom seen Metro North bike racks.

Stromer ST1 Electric Bike

I you eat your Wheaties, you’ll be able to bring the bike up and hook it on the rack. When I did this, I heard no creak and because it is still the relative size of a normal bike it did fit.

While sitting next to it on the train ride back, I got to look at the bike in such a way I was able to understand where all of the weight was coming from. The 500W motor in the rear hub. The 36 volt lithium ion battery stowed in the bottom tube. The rear rack and fenders - all of it gives the bike heft.

Still more weight comes from the unusual and optional seatpost A Cane Creek Thudbuster. I’ve been familiar with these for a while and would write a song about them if I could. Any bike with a hardball aluminum frame (like the Stromer ST1) needs one of these. It just makes a more comfortable ride.

So yes, this is a heavy bike. That can’t be sugarcoated. But then again, you get something for all of this heft. To find out what it is, you have to turn the bike on, select the ‘Power’ mode, and begin pedaling.

Stromer ST1 Electric Bicycle

With the fat Big Ben tires and the solid frame, the bike doesn’t feel like anything other than an electric assist battering ram when riding. Pedaling at a pace that feels like ten miles an hour while the spedometer says you’re going double that is a grin-inducer, to be sure. Not only that, but the bike has regenerative braking that puts power back into the battery when you slow down - which is not a common feature.

I’m going to have to put this bike through some paces - including, but not limited, to a hilly, 20+ mile ride. I’ll let you know how that goes shortly.

Winter is Coming? Meet the BionX powered Surly Moonlander.

The Mars Rover meets Surly attitude in this space age electric bike.

Surly Moonlander powered by BionX D-Series

One of the things I value most in a bicycle is its reliability in any terrain. Even in NYC, you can encounter hills, potholes, gravel, and glass – not to mention spontaneous rain and snow. While sleek city bikes are stylish and lightweight, I don’t always feel comfortable taking them too far.

At a glance, you KNOW this won’t be an issue with the Surly Moonlander. The tires alone live up to the name — they’re big (and I mean BIG — 4.7 inches wide big) and knobby enough to take a joyride on the moon.

Surly Moonlander electric bicycle tire with BionX

BionX D-Series: A match made in heaven

The BionX D-Series motor powered assisted pedaling is a godsend in a bike oriented for rough terrain – the acceleration of the motor is buttery smooth, taking you from 0 to 20mph in seconds. In the stop-and-go streets of Manhattan, I was leading the pack of cars with ease.

Electric Surly Moonlander Cassette with BionX

Some electric bikes can’t handle the speeds reached with a motor helping you out, making the ride feel bumpy and brittle. The Surly Moonlander and the BionX D-Series is a match made in heaven. Thanks to the cushy tires, I was sailing over potholes, glass, curbs, and lawns at over 20MPH and couldn’t even tell the difference.

Handling the Moonlander

It’s a Surly bike, so the breaking is predictably perfect. They’re soft and gradual, unless you slam down on them in an emergency – at which point you stop on a dime.

The only thing more shocking than the massive tires on this bike is how lightweight it is. It’s a formidable electric bicycle – easily one of our biggest in the shop – and yet it was one of the lightest electric bikes we own, weighing in at ~45lbs.

During my test tour, I was riding in the slick mud and leaves of Central Park and never found myself slipping or losing control. Even pedaling straight up jagged rock formations was possible!

A Clear Winner

The Surly Moonlander is to all-terrain what the Stromer ST2 is to speed and power: the absolute best in its class. The space-age look and crazy performance is sure to draw attention. Through rain, snow, or some sort of Indiana Jones adventure, the BionX powered Surly Moonlander will not let you down.

Victoria Foe customer review E3 Metro

These days there are so many different electric bike models to choose from, it can be difficult to decide which is the right one for you. There are ultra fast sporty electric bikes like the Stromer St1 Platinum, lightweight electric folding bikes like the Formula BionX bike, cruisers like the A2b Alva + or affordable best-bike-for-the-price electric bikes like the iZips.

Electric bikes

The best way to learn about a bike is to hear directly from someone who purchased one. Here is an email that we got from Victoria, a customer who purchased the iZip E3 Metro, and wanted tell us her thoughts about her new bike:

"Dear Peter et al.,

My iZip 2014 E3 Metro arrived a week ago and I have put well over 100 miles on it. I love its sturdy body, its low center of gravity stability, its large load carrying capacity, the always active on-demand twist throttle and the cadence Pedelec sensing which makes the Metro take off smoother than for my husband's Pedego Commuter.

The Metro replaces my old and now dead LA Free mid-drive e-bike that used torque sensing. That little bike felt more powerful for hill climbing, but I think that is what mid drives are noted for.  In all other ways the new Metro is better--including its five or six-fold increase in distance per battery charge.

The 2014 Metro is a beautifully designed e-bike and prefect for my needs, which include an 11 mile RT rural commute plus frequently a side trip into town for  groceries. Here is to the no fossil fuels commute!

Thank you.

Victoria F."


We'd like to thank Victoria for sending us this very informative email, and we hope that it will be useful to anyone who has just started looking at the different e-bike models out there. Take it from Victoria, if you want an electric bike that has great range, stability, durability, and a lower price, the iZip 2014 E3 Metro is a great choice!



Reviewing the Brompton Electric Bike

Electric Brompton BikeToday, I took the E-Brompton for a spin. It is a fantastic custom electric bike, and initially it doesn't even look electric. The hub motor isn't immediately noticeable and the battery is well stored and hidden in the front bag. Just like on a standard non-electric Brompton, this front bag is still quickly removable. Disconnect the battery from the bike, remove the bag from the carrier block, and you'll be able to charge your battery inside. And don't worry, the battery is in a separate pouch and doesn't take up much room, leaving tons of space for your own luggage.

The Electric Brompton is nimble and powerful

Brompton Electric BikeRiding the electric Brompton bike is a breeze. The motor's controls are ultra simple for setting speed and the thumb throttle is very convenient. The whole E-Brompton setup still weighs under 45 lbs, less than many old school steel road bikes I've owned. This definitely takes the Brompton to the next level as a commuting option. With electric assistance, you'll be able to ride longer distances without breaking a sweat, and when you get to work you won't be exhausted and in need of a change of clothing. So fresh and so clean! (clean!).

Does the Electric Brompton still fold?

Electric Brompton bikeThe electric Brompton bike folds up just as quickly and easily as a non-electric. Although technically you can fold the bike with the bag still attached, I found it easiest to remove the front bag first, just to give myself a little more breathing room.

From here it's all business as usual. Fold the rear wheel underneath the frame via a quick release, unscrew the hinge at the center of the top tube and swing the front wheel to the right and back towards the frame, loosen and fold the handlebar with a few twists, and blammo, your electric bike can fit in your closet or be checked on an airplane.

For a more detailed description of how to fold the Brompton bike with large high resolution pictures, check out this folding bike blog.

Does an electric bike work with gears?

Electric Brompton Bike MotorBecause the motor is in the front wheel of the Brompton bike, it can be used simultaneously with the gears. The important thing is to use a Brompton that has a high gear range. When you hold down the throttle, the E- Brompton will shoot you forward at 20 mph, and with a single speed Brompton, you wouldn't be able to pedal fast enough to actually engage the transmission. The model I tried was a 3 speed version which has a nice high gear range and worked well in tandem with the motor, allowing me to pedal along comfortably while pushing 20 mph.

Electric Brompton bikeA powerful and innovative Electric Bike

The Electric Brompton is one great ride. It has all the convenience of the original Brompton, the same compact fold, the same flawless craftsmanship, with the added power of an electric motor. Anyone who wants an electric bike with great range and power, and needs it be compact enough to fit in their New York apt, the Electric Brompton bike is the way to go.


E-Brompton Banter—Part 11—My Gen-E-ration, by Turbo Bob

Electric Brompton TurboFollowing the timeline of the Who is kind of like following my own, my interest in bikes and that of the E-Brompton. The Who cranked out this wild tune in 1965, just a year after they came together as a band. Said to be one of the top three rock groups of all time, these British rock and rollers are still making history with every appearance. This song is about trying to find a place in society, something many E-Brompton owners might be able to relate to. Then again, why try to fit in when you know you are happy and doing the right thing?

The 60’s were a time of enlightenment and turmoil. Adults had mostly turned away from bicycles to embrace the motorcar. What had been a main source of transportation and relaxation for all was mostly enjoyed by the kids during this era. I know this for a fact because I was one of them, and loved the freedom and excitement bikes offered me daily. That was (and is), “My Generation”.


As I rode and fixed my bikes, I found other interests through home-made electrical devices and music (among others). My bikes allowed me a chance to be myself, free from boundaries and depending on others. At the time I never envisioned a bicycle with an electric motor, even as I would spend time with my cousin who had built a wagon powered by a salvaged washing machine power plant. He was tethered by a super-long extension cord, something that didn’t match my fancy. I was soon to be enamored with stinky, noisy gasoline power, like so many others of my time.


As the 70’s began, I was off and running with the two and four wheeled crowd, loving my hot rods and motorcycles. With every visit to one of the local race tracks, competing with roaring exhausts made my dreams of the era come true. It was during this time I earned my nickname building little econo-cars into muscle car stomping machines. I’ll never regret those days, but also, I’ll never repeat them.

E-Brompton in Santa BarbaraDuring this decade a man in England was finding the need for a folding bicycle that could change the way we get around. Andrew Ritchie was up and running, getting the name “Brompton Bicycle” a place in two-wheeled history. Even though it only really hit mass-production in the late 80’s, Brompton started to get accepted in the bicycle world.


The eighties saw music change, yet the Who stayed true to their fans. This whole 10 year period still saw me high on gasoline, as a mechanic and racer. Bicycles rarely entered my mind as my heavy foot played a different tune. Sure I rode a bike now and then, fixed some for the neighbor kids and kept just the smallest lookout for new trends. Yet if I couldn’t fill the tank, it wasn’t my kind of ride. Shame on me.


Enter the 90’s. Brompton sales and interest started taking off. The Who continued to play to sold-out crowds. Adults got back on their bikes, following a green movement, exercise, freedom and fun. I was one of those adults, getting a Schwinn college bike from a friend in 91. My youth was rediscovered, the thrill was back, I was in love with bikes once again. My cars were idled much of the time as I took my bike more and more places. It was during this time I got my first taste of an E-bike. Crude, yet very eye-opening to be sure.

http://www.nycewheels.com/brompton-electric-bike.htmlInto the next 10 years my cycling expanded. I met my wife and she too was so happy to get on two wheels once again. Still with no E-bikes in our horizon, it didn’t matter, bicycle riding was fun and smart. We were both like minded in the three R’s---Reduce, Reuse, and Recycle. Before long we were looking for a way to commute by bike. Sure bikes added fun to our lives, but we wanted more.



Enter our E-bikes. After some investigation we got a pair and never looked back.

It was during this time I was reintroduced to folding bikes by NYCeWheels. With a flashy raw lacquer M3L Brompton, I was blown away with everything it offered. (I’m sure you’ve seen my series of articles, “Boy Gets Brompton”). Bikes are awesome, but one that folds and rides great is incredible. All my past times with riding and repairing folding bikes disappeared in my memory as I found the Brompton had none of the weaknesses and problems of those bikes of old.


NYCeWheels sold their first Brompton back in 2005, and it wasn’t long before the founder, Bert Cebular, envisioned mixing his love of it and electric bikes into one. With determination and an experienced crew, the E-Brompton started to take form. Once it was perfected, it became an instant hit. The first one left the sales floor in 2012, with many more to follow. I’ve been riding mine for over two years and have chronicled my times with it many times here on the NYCeWheels blog sites.


Turbo-and-the-E-BromptonThis E-Brompton is so well engineered. Taking the lead from Mr. Ritchie, NYCeWheels moved forward with some great innovations. All the extra components are secure and tucked in as not to affect the fold. The quality and longevity are proved to me with every ride. This E-Brompton has been on several vacations, been ridden by so many first time E-bikers and generally been like a right hand man. If you have been following along with this series of articles then you have half a clue to the way I feel about it.

The E-brompton is a bike for my generation, generations past, present and future too. I am sure with the first ride you will feel the same.


BTW, if you hurry I bet you can still get some tickets to the Who’s latest sold-out concert. Turbo Bob.

The A2B Metro – the MoPed Electric Bike

a2b-metro-bike-ultra-motorThe first thing you notice about the the A2B electric bike is that it looks very sturdy. Big beefy 3 inch tires, disc brakes, thick durable Tig Welded frame, with giant ultra strong rear rack sticking out the back -more than any other electric bike in the shop, the A2B has the look of a Moped.

The most comfortable electric bike

This is not to say that you should try going off jumps and doings flips. The A2B looks more like a gas powered mini motorcycle, but it is more of a cruiser than a racer, more a lover than a fighter. First and foremost, the A2B is just incredibly comfortable. Its seat is wide and cushy, and the handlebars are situated relatively close to you, allowing for a more upright riding position, which puts more weight on your sitting bones and less on your wrists. The front and rear suspension are fantastic, allowing you to glide over bumpy streets and trails as though nothing is there. And the thickness of the frame provides extra durability. Of all the electric bikes I've tried, the A2B is definitely the cushiest.

Powerful Electric BikeThe A2B is fit with a powerful motor

The A2B is also a very powerful electric bike, fit with a 500W motor and a 36 volt lithium ion battery, which fits nicely inside the down tube out of sight and out of mind. This hi wattage motor is combined with a high torque engine making the A2B Electric Bike great for towing a lot of weight. The A2B which we keep here at the shop has a trailer hitch fitted to it so that we can use it to haul equipment, bikes, and other heavy inventory. Once we folded up three brompton bikes, put them in a cart, and used the A2B to haul them all the way from the shop to an exhibition in Tribeca and back. That's around 25 miles hauling about 300 lbs of weight in total!

Just the right amount of Pizzaz

Because of the thickness of its frame and it's numerous components, the A2B is not one of our ultra lightweight electric bikes. Nevertheless, it has great range, particularly if you attach a second battery to the rear rack, as most savvy riders are wont to do. With two batteries at your disposal, you could potentially ride 40 miles or so before having to recharge.

A2B Electric BikeOften customers ask about which electric bikes are the lightest, or which look and feel most like regular bikes. But what I like about the A2B, is that it embraces its ebikeness. Where most electric bikes have pared down frames to minimize weight and increase sleekness, the A2B lets it all hang out, turning heads with some pizzaz. If you're looking for a bike that's nice and beefy, ultra comfortable, but that still has great power and range, the A2B electric bike can't be beat.


BionX for Beginners

There's no doubt about it, we live in an age of wonders. When I was a kid, I loved science fiction, imagined a future of flying cars, teleportation machines, voice activated George Foreman grills that could produce a perfect medium rare steak in seconds, but it never occurred to me that the tech already existed to super charge my old trek bicycle with an electric motor conversion kit.

Maybe if I had spent less time watching Night Rider and more time reading science magazines I would have seen the electric bike revolution coming. As it is, according to a wiki article on the subject electric powered bikes made up 10 to 20 percent of all two-wheeled vehicles on the streets of many major cities by 2007, and the trend is only just beginning. Earlier this month I watched the first footage of an electric powered flying bicycle. My 8 year old self stands agog.

Powerful electric conversion

Powerful electric conversionThe electric conversion kit has got to be one of the most fantastic inventions of the 20th century, and as time goes on, the technology for it gets better and better. One of the most advanced kits on the market is the BionX conversion kit, capable of converting pretty much any regular bicycle into a powerful motorized vehicle capable of 45 miles on a charge and 20 mph top speeds.

But let's not get ahead of ourselves.

What is the BionX conversion kit? How does it work?

350-watt-bionx-kit-for-surly-fat-bikesWhen you convert a bicycle into an electric bicycle using the BionX conversion kit, you replace your rear wheel with a new wheel which has a motor in it. This motor is powered by a Lithium Ion battery which is mounted to the frame of your bicycle, and is activated using a console that is mounted on your handlebars. The battery is easily removable, and comes with a charger that can be plugged into any normal 110 wall socket. It takes about 4-5 hours to fully charge the battery. Your bike is still a bike, and you can still pedal it as usual, but now you can press a button and the motor will kick in boosting you along a flat at 20mph, or helping you up those pesky hills.

The BionX uses pedal assist

BionX ConsoleSome electric bikes use a throttle to activate the motor. In the case of a bike like the A2B Metro, the throttle is on the grip itself, just give a twist and you'll feel the motor kick in, whether or not you happen to be pedaling. On the BionX kit there is a throttle, which exists in the form of a small red button which you push with your thumb, but actually the BionX works best as a "pedal assist" electric bike.

Using the console on your bars, you select one of four levels of assistance ranging low to high, the motor then works in tandem with your pedaling cadence. At the lowest setting, the motor will do about 25 percent of the work for you, at highest, it will boost you along at 20 mph with absolutely no effort required on your part. What results is a system that is more powerful, more efficient, and more intuitive than a throttle activated system.

Are there different types of BionX kits?

There are three different BionX kits. The cheapest is the pl250 conversion kit, which uses a 250 watt motor, and a 26 volt Lithium ion battery. This is the entry level kit, lighter than most other kits on the market and with decent power and range.

The next step up is the pl350 BionX kit. This kit uses a more powerful 350watt motor capable of faster acceleration, and is powered by a larger 36 volt battery for more range and power. This kit one of the most popular as it offers more range and power at a mid range price point - a good meeting point between affordability and high performance.

Electric Conversion KitThe last option is the premium Sl350 BionX kit. This is the most advanced BionX conversion kit currently on the market, using a more powerful 48 volt battery for increased range and power, while maintaining a light weight. Including the motor, battery, and console, this kit will only add around 18 lbs to the weight of your bike. This means that if you convert a road bike that only weighs 25lbs to start out with, you'll end up with an electric bike 20 lbs lighter than most other electric bikes on the market.

So there's the basics! Hope this was helpful as an introductory guide. Check out the BionX conversion kit, and see where our future might be taking us.

All the best,
