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
The 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?
When 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
Some 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.
The 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,
Riding a bike is fun. I wanted to start out with something we can all agree on. If I've already lost you, then you might want to rethink the statement. Sure, there are other reasons to ride---transportation, health, job, money and the such. Yet when it all goes full circle, we come back to the fun factor.
My point is that if we want to have fun while we ride, then riding a fun bike is sure going to be important. Everyone has a type of bike they might enjoy more than others. What I've found with this E-Brompton is that it can be almost each and everyone of those bikes. It is fun to ride. It can make the perfect commuter. Even though it has electric-assist, you get to choose just how much exercise you want to receive. It can be used for touring, saving money, saving the planet and many of the other reasons you ride.
The base bike is a rock-solid folding and riding machine. A stock Brompton is truly a bundle of fun by itself. Then with a little of magic from the crew at NYCeWheels, it is transformed into something even more special. They perfectly add the few items that neatly and nearly turn it into a flying carpet. Not that it’s so much faster, or better looking, just that it is so much more versatile and fun. And fun is what we are talking about.
They can convert your Brompton if you like. Or you can pick out just about any combination of options and colors for your new Brompton and NYCeWheels can covert that before you get it. Mine happens to be an all white H3L. The H stands for the 2 inch taller handlebar stem, the 3 stands for the three-speed rear hub gear, and the L stands for lectric---just kidding, you know, having a little fun.
Building a great electric folding bike
The skill put into this conversion is mind-bending. They source all the parts from almost 30 different companies. The narrow 250 watt direct-drive motor is a drop-in piece that helps maintain the Brompton factory warranty. These pieces have no affect on the fold and just the smallest effect on the fold size. Sure some weight is added, something you’ll never notice during the ride. And that extra heft is divided between the bike and the ‘C’ bag so lifting it and carrying it isn't much tougher than before.
So, you might ask, what is so much fun about an E-Brompton? I knew I wasn't going to be able to avoid that question. For one, I get to ride it. Any bike you might ride will almost always deliver the fun you seek. Even a beat-up rusty klunker (not a description of this E-Brompton) can turn an afternoon at the beach into a day to remember. Fun factor #1---bikes are fun.
Part of the thrill (read fun) of an E-Brompton (any Brompton for that matter), has nothing to do with the ride. It has to do with the razzle-dazzle of the fold. Many are awestruck just to watch it turn back and forth from a bicycle to mini jumble of paint and wheels. If you own one I need not go any further on explaining how cool that is. My favorite is, “How long does it take to put your bike back together?” And then, BOOM, they can see it all and understand. Now that is fun!
So, I’m sure you can see that this post is about why having the electric-assist makes a Brompton bicycle more fun. Just imagine a stiff head-wind, a gradually rising grade in the road or even a hot day that rolls through your body like fire. Then imagine a invisible superhuman arm taking off the load and helping you and your bike keep moving smooth and easy. Just the imagining part is fun, but the real-life help of motor and battery is even more fun.
A throttle powered folding bike
If you are so inclined you can raise both feet in the air and power down the road at about twenty like a motor scooter. Generally you won’t, but every now and then it’s worth it. Most of the time you find that adding about half the driving power with your legs and the other half with the motor-assist works the best. Or too, you can pedal like normal almost all the time and just add a little power on the tough hills. These my friend, are part of the fun that having an E-Brompton can bring.
Trying to explain an E-bike to someone who hasn’t tried one can be tough. I have let so many people have their first experience on one and it is only then that the full realization of how great and fun they are comes into their minds. This too is part of the big fun of an E-Brompton, sharing that fun with others. You might be tempted to keep that part to yourself, your decision.
How do I have fun? I think you know now.

Reading this guest review of a BionX-powered Crosstown from Montague really reminded me of my first time riding an electric bicycle--especially the part about the uncontrollable smiling! Enjoy!
Today I got to ride the Montague Crosstown with BionX SL350 48V Electric Motor Kit. This is the first electric bike I've gotten to take for a good honest try and I did not want to stop riding once I started. Riding this bike was the most fun I've had in a very long time and I had the biggest ear to ear grin on my face during the whole ride around the park.
For starters, the Montague Crosstown is a Full Sized Folding Bike with 700c wheels. It has a rigid frame and a very quick and sporty feel to it. The 7 speed gear system really came in handy when I'd approach a hill or steep incline. Given its range of gears and 700x25c tires, this bike is really quick on flats and cruised up to 20 mph with ease. This is definitely a great bike for someone that wants the versatility of a hybrid style bike coupled with the more compact storage capabilities of a folding bike.
The BionX SL350 48V Electric Motor Kit made this already good bike an AMAZING bike. It has a few different assistance modes that I got to play with. It can be set-up to give you just a little extra boost when you are pedaling or you can hit the throttle and zip along enjoying the full power of the motor on demand. This was the first time I've ridden a bike with an electric motor kit like this. The pedal assist mode is great for the individual that wants to get good exercise but when you need a little extra help getting up that steep hill the BionX Kit is there to help you. The speed and power that you get from this kit is just incredible. Whether you want to pedal or not this thing hits 20 mph almost instantly. Its got plenty of power, great battery life, and a fun factor that is second to none! Overall this thing was just a blast to ride and had me feeling like a kid again. Every minute that I was riding it was a minute spent with a smile on my face.
If you want to feel like a happy kid again too, head over to the NYCeWheels website and check out the BionX-equipped Montague Crosstown!
E-Brompton Banter---Part 9---E-xtended Test
by Turbo Bob
When the great folks at NYCeWheels sent me this electric Brompton for testing a year ago, I figured it would be a 2 or 3 month excitement that might someday fade from my memory. As 3 months turned to 6 and now to 12, I know that myself and all that have gotten the chance to feel the magic this bike offers will hold onto the thrill for years to come. This isn't just any every-day, throw-away bike, it is special in a way that is both easy and hard to describe. As I put pen to paper (so to speak), let me try.
The Electric Brompton is the perfect folding electric bicycle for...everything!
Me being a 5 year + E-bike veteran, I have ridden so many different variations of them. Fast and slow, big and little, inexpensive and very expensive E-bikes have come and gone my way as my bike blog exploits continue. Yet none have offered the utility and convenience I have received from this H3L E-Brompton. Blazoned in bright white and powered by a compact 250 watt direct-drive front hub motor, this bike has been so many places and racked-up so many miles I can barely remember them all.
Tucked in the trunk, taken on public transportation, long group jaunts and just simple rides for local errands are all part of the resume it deals up. I have offered the controls to more friends and new friends than can be counted. It has been on radio interviews about E-bikes, tried at my bi-yearly E-bike seminars and might soon be seen on the pages of my local newspaper in an article about the blossoming desire and technology for E-bikes. Ridden in the mountains, at the beaches and city streets, I have put it though most every type of riding you could imagine.
The convenience of a folding bike meets the power of an electric bike
If you are reading this then you probably already know these facts. Folding bicycles are great. You can take them almost anywhere you go. The Brompton is as rock-solid as they come for all types of riding. It folds to the smallest of packages. It rides just as good as any full-sized bike. Security isn’t an issue as you can tuck it under a desk at work, under a table at an eatery and carry it inside at day‘s end. With three-speeds and an up-right seating position it is as comfy as can be.
E-bikes are great. They can help you up a grade or into a brisk head-wind. They can shorten the longer rides. You can arrive at your destination fresh and refreshed. Folks with conditions that make riding a regular bike tough or impossible can really take advantage of the benefits they offer. They put the fun in riding for so many people.
When you add the fantastic electric-assist to a convenient folding bike you get one of the best products ever in the bike world. That is where the E-Brompton really shines. It has just about everything one could ask for in a bike. Power to spare and utility come oozing out of every seam. Even people who were skeptical at first, after a quick explanation or ride, were also convinced this bike has so much to offer.
I will be the first to admit that way back I was not a big fan of the weak and flimsy folding bikes I tried. Plus after my first E-bike ride some 20 years ago, even though it was interesting, I found the bike was very heavy, slow and had the shortest of range. Times have changed and the E-Brompton is proof of that. Smooth, quality electric-assist mated to a rock-solid well-made folding bike is what the E-Brompton offers---nothing more and nothing less. It is hard not to lay it out that simply.
Electric Brompton: a labor of love
You may know that NYCeWheels worked very hard to come up with this combination. It is a labor of love and it shows with every stroke of the pedal. The only issue I’ve had in a year of riding this bike was one flat rear tire that I blame on a too wide rim strip, and which was repaired with a quick and easy modification of the factory part. I invested in a new tube and I think we can all agree that is small change for a year of fun and extensive riding.
I guess I will continue this extended test. For how long? Who know? What I do know is that I am loving it and the ride and reporting won’t stop this month or next. Thinking about getting your own electric Brompton? I say “Go for it!”
“No excuses.”---Ted Smith.
My name is Jack, an employee at NYCeWheels bike shop in NYC. At the shop, part of my job is to connect with communities of cyclists via social media outlets. This is a two way street-- we post pics of our bikes, links to the most recent videos reviews etc, and in return people send us their own stories, pics and videos. This is really the best part of my job, getting to be a part of people's passions, being given a window into a wide variety of creative and innovative projects. Some of the most interesting projects I've come across are from cyclists looking to convert their bicycle into an electric bike via an electric bike conversion kit. Many of the most creative electric bike conversions have involved the BionX Bike Kit.
BionX- versatile electric conversion kit
Just to give a little background, the BionX Bike Kit is an electric conversion kit, which allows you to convert virtually any regular bike into a powerful electric bike. The versatility of the BionX Bike Kit makes it popular with e-bike enthusiasts looking for creative ways to electrify their bikes (and other wheeled contraptions).
The BionX on a Recumbent tricycle
Converting a recumbent bike with an electric conversion kit is such a logical and brilliant idea, that I wonder that I'de never considered it before. Here's a good example sent to us from Brenden, a past customer who installed the BionX Electric Conversion Kit on his Scorpion Recumbent Trike. You can see the BionX on the back wheel. Aside from having a killer look, the Scorpion makes a great choice for electric conversion, due to it's large wheels, and nice comfy seat. Whenever you need a break, just lean back, and let the motor carry you along in comfort. Man I really need to get me one of these.
BionX on a wind powered trike. What? Oh Yes.
This is probably one of the most eccentric electric conversions I've come across, the BionX Powered Pterosail Trike. This was built by Pterosail Trike Systems in 2010, who announced they would be taking their wind powered trike cross country as a triumph of green technology. The trike is meant to be powered primarily via sail, but, when the wind is lacking, the rider can activate a 36o watt BionX motor attached to the back wheel, to help motor along in the interim. This is so amazingly cool, I don't even have the words.
Custom BionX Mods
As BionX conversion kits become increasingly well known, we're starting to see some really great custom jobs. Some of these have been pioneered by my coworkers here at the shop. Last year we created an electric folding Mountain bike, installing the BionX Motor on the Montague Paratrooper. And just last month, my coworker built up one of the first electric fat bikes, installing a motor on the Surly Moonlander, featuring impressive 4.7 inch tires.
Other Custom BionX Conversions have come straight from past customers. One of the most creative and prolific E-bike pioneers has been Paul DeGarie, who has sent us a steady stream of impressive Custom BionX conversions on a variety of different of different bikes.
As the new 2013 season gets off the ground, I look forward to seeing what electric conversions we'll be seeing next. In a world where bikes fold, have sails, and can be electrified via powerful conversion kits, anything seems possible.
Yes, this E-Brompton is looking good, in the city, suburbs or the country. It has lines that are unmistakable and loved by many. Even though it has been converted to an electric-assist bike by NYCeWheels, it is all Brompton. The arch of the frame and the rise in the handlebars just talk to me. No, I’m not going batty, just speaking my mind without inhibitions.
For many of you, the sexy look of a Brompton is an everyday excitement. Whether you already ride one or are saving your pennies to get one, you have the bug. Just a glimpse of one of these fast moving folding bikes is enough to bring converts into its graces. If the profile doesn’t get you, the scene of the folding procedure will pull you in.
How will you look when riding a Brompton? Well, if the bike looks awesome, you should reflect the same. I know I am no GQ model (although I am featured in the centerfold of a brand X E-bike catalog), I think I look pretty racy saddled up on this fancy electric folding bike. With no sweat on my brow or a strained appearance on my face, my smile when riding makes for a pretty sight. My E-Brompton and I are quite a vision as we pedal by.
My H3L E-Brompton is white, which I really think pops. Of course, they come in lots of great colors and even combinations of colors. A raw lacquer Brompton with the E-conversion would be especially worth riding. You may have seen some of the custom painted and decorated versions of this folding bike I have posted on the NYCeWheels Facebook page. One of those with electric power could be like a color explosion.
The Brompton Bike Community
Brompton riders are kind of like their own club. They band together and even share a wave or ring of the bell as they pass. The smile from anybody riding one of these is contagious. People look their best when they are with friends and happy. Even if you are riding on your own, you can consider your bike as a friend and that makes you happy too. Content riders just look sexy.
Poetry in motion can be one way to describe an E- Brompton and its passenger as they roll down a city street. The smooth cadence of the pedals, the quiet power of the 250 watt front hub motor and the peaceful calm of the riders thoughts are the dreams of many. The serenity of security this folding bike gives you at each stop adds to the rhyme of the ride. A Brompton, E-powered or not, can make your life a living dream.
When you ride one of these alluring folding bikes you might want to dress the part. Your Sunday best, your Saturday grubbies, or a classic English outfit might bring it all together for you. For me, short pants, a t-shirt and sandals do the trick. That’s my daily uniform, but I have been known to dress up in tweed and argyle for special occasions. Clothes might make the person, but the bike can make the difference. Add a Christys’ Fur Felt Bowler hat for the full effect if you feel the need.
Fashion can have a lot to do with the Brompton lifestyle. Any garb will do, but for large numbers of riders, the sexy look of a Brompton needs to be highlighted with some fancy threads. A loving couple, dressed to the tens, on a pair of these folding E-bikes is a sight we all love to see. So hit the mall, check your tire pressures and take to the city streets on a E-Brompton for the thrill of a lifetime.
Sexy is as sexy does- Turbo Bob.

As a member of the London Brompton Club, I get to see a lot of what is going on in this great folding bike’s 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’.
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
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?

What a great time it is for electric bikes. The quality and ride keep getting better, as the weight and inefficiency gets trimmed. I just got the thumbs-up to be involved in an extended test on one of NYCeWheels’ E-Bromptons and I couldn’t be more excited. As Izzy builds this great converted Brompton for me, I will spend some time to think and dream about the pleasures to come.
You may have read my ’Boy Gets Brompton’ series of articles on one of the NYCeWheels’ sites. I got to spend three months with a Raw Lacquer M3L and came to understand it very well. Some of the stories were a little whimsical, but overall, I really got to dive deep into all the plusses and the few minuses of this great folding bike. Bottom line is, I love Bromptons.
As too, I love E-bikes. The electric-assist bike has been carving out its place in this world, and the word keeps getting spread. Great for so many people and reasons, adding a electric motor assist to a bike can make all the difference for utility and recreation riding. So what better combination then the ultimate folding bike, paired with an electric-assist system? It would seem to be a match made in heaven.
So let’s talk about the bike headed my way. First off, the base bike will be the new H3L. This brand-new version has a longer stem that allows the handlebars to sit two inches higher than the original layout. This will not only lend to my comfort (my 6’ 2” frame), but to the comfort of all riders who desire a more up-right seating position. This up-dated model still has the same super small folded size, and every great feature the L model offers. That includes fenders too.
You must know by now that you can get your Brompton bike in the most cool selections of colors. You can mix and match, or have yours in all one color. NYCeWheels offers their basic E-Brompton in black or white, but for a little extra, the color palette is wide open. They can also convert your existing Brompton to an E-bike so your color style doesn’t have to change. My new H3L E-Brompton is going to be the ‘in-your-face’ white. Talk about standing out in a crowd. It should be awesome.
The E-bike conversion is one that they have perfected to a ‘T’. With quality pieces from twenty different sources, Bert and Peter (Izzy too) have gone far out of their way to make sure this bike is right on the money. I’ve seen the videos and poured over the specs, and I am sure this E-bike won’t disappoint. My desire for the increased capacity 10 Ah battery was oked by the shop, so my fun rides will be extra long.
The battery will fit into the included ’C’ bag that impressed me so much on my last Brompton bicycle test. It has many pockets, is water-resistant, and comes with a water-proof cover bag just in case you want to ride in wet and wild conditions. There will be plenty of room to keep the battery charger in the bag so it will be handy when I am out-of-town. And believe me when I say, I plan on taking this bike to some far-away places. That is just one draw of a folding bike like this.
With a strong 250 watt front hub motor, I expect to have all the power I need. It will be a brushless and gearless motor. That means it will be quiet and efficient. With virtually no moving parts, it should last longer than who knows what. A thumb throttle will allow me to use the power when I like, with none wasted. That should net me some long rides with an easy way to the top of any hill or grade I encounter.
The whole conversion will add about 18 to 20 Lbs to the overall weight. It might make carrying the bike a little tougher, but almost half of that will be in the detachable carry bag, so I don’t expect it to bother me too much. And any weight penalty will be more than overcome by the power which the motor will add to my legs. If you have ridden E-bikes, you fully know what I’m talking about.
So, as I wait for the delivery driver to make his way to my house, I know that this E-Brompton will make it all worthwhile. Expect to see a flurry of articles about my new folding bike hit these pages. Take this time if you will, to read the ’Boy Gets Brompton’ stories to find out more about my take on Bromptons. Also, I hope you get a kick out of my E-titles for each post.
Thanks for reading, Turbo Bob.
Of course, you could always just order your own E-Brompton and find out for yourself... or an convert your current Brompton to an eBrompton.
“It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.”---Ernest Hemingway, By-Line.
Picking out the best electric bike motor kit can be difficult if you're not really sure how an electric bike operates. There are electric bike kits with different kinds of batteries, controls, and motors. Picking out the best kit requires a basic knowledge about how each component works. Getting past the quality of each part, there are certain aspects of an electric motor kit that depend on the preference of the rider. For example, is an electric motor better in the front wheel or in the back wheel of the bike? Neither choice is better than the other, but there are certain advantages to each one.
Front Wheel Electric Bike Motor Kit
The front wheel motor is a common piece of the electric bike motor kit, because of the ease of installation. Just remove the front wheel and pop on the new motor wheel and you're finished! Usually, these types of motors work with a throttle-based electric bike motor kit, such as the eZee Bike Conversion Kit. It feels a bit like getting "pulled" by the bike, rather than "pushed," but with the weight of the rider and battery in the back, it's a nice equal weight distribution.
Another advantage of the front hub motor is the ability to install internal hub gears inside the back wheel. This type of low-maintenance electric bike, with a front hub motor and rear hub gearing, has practically no problems as an everyday commuter bike.
Rear Wheel Electric Bike Motor Kit
The rear wheel motor is a great choice for electric bike motor kits that utilize a pedal-assist mode. Since the motor is attached to the gears, a torque sensor can actually measure how hard the rider pedals the bike. This is utlizied in the versatile BionX electric bike kit. With a pedal-assist bike, the added pedal power takes much of the strain off of the battery, and the bike can travel much further on a charge. On a BionX bike, there is an option to push a throttle for an added speed boost.
Rear wheel motors tend to feel like they're "pushing" you, rather than "pulling," which doesn't change the feel of the bike too much, but tends to be easier to power around sharp turns.
Ultimately, the location of the motor is up to the preference of the rider. Some people enjoy the front wheel for its easy installation and ability to work with a rear hub, while other people like the torque sensitive rear wheel and "pushing" sensation.
Both options are available at NYCeWheels as electric bike motor kit options.
