When you need the power of an electric bike and want to keep the weight of your bike as low as possible, the Bionx PL250 is the way to go. The PL250 offers a 250W motor and a 26V Li-ion battery. Converting your bike with the Bionx PL250 conversion kit will make your commute faster, ease your exertion, and make your rides more fun!
Bionx PL250 features:
The control console is easy to operate, with two main buttons to increase or decrease the amount of assistance to the bike. The lowest assistance setting gives a nice boost after a few pedals, and while cranked up to the highest setting your pedaling will trigger a rather powerful thrust. Below the assistance settings you can always pedal with no assistance or dip down into regenerative mode. In regenerative mode, and whenever the brakes are used, the battery will actually use the wheel resistance to get a little more charged up. Use this going down hills to get a longer life out of your battery, but don't forget to plug it in at home to fully charge up!
The Bionx PL250 is lightweight and is an excellent choice for most riders. This is an efficient and exciting option for someone looking to convert a bike. The PL250 offers riders the option of getting to a destination faster, with less effort, and while still being friendly to the environment.

BionX is Both, Electric and Exercise
With four assist and four regen modes, BionX is a pedelec system and a training tool. Canadian manufacturer EPS is preparing to sell the compact hub drive unit also in Europe.
In September 2004, Canadian Electric Power Systems manufacturer EPS presented the pedelec hub drive system BionX for the first time in Europe. It was exhibited at IFMA in Cologne, Germany and Vel Expo Ticino in Lugano, Switzerland.
The 250 Watt hub motor including power sensor and electronics comes in a ready-to-use rear wheel. The 8 Ah, 34 V NiMH battery is located in a compact battery box. To mount the system to any regular bicycle one only needs to exchange the rear wheel and attach the battery box to the frame. To do so, one simply uses the bottle holder screw holes to mount the battery holder.
On the display at the handlebar the user switches on and off the electric system, the light, and chooses the riding mode. There are four assistance modes ("A" modes): 25, 50, 100, or 200 percent. Four 'G' modes are energy regeneration options. The higher the resistance, the more energy is generated to recharge the battery. Also shown on the display are cumulative kilometers, speed, and battery data such as cycles, special happenings (deep discharge etc.).
The entire electric bike system weights 6.6 kg. The motor, controller, cables and display weigh 2.5 kg, and the battery 4.1 kg. This makes the BionX the most compact power sensor system for pedelecs, which is not from Japan. It does not only make riding easier, in the G-modes it can also be used as a training tool. The range even more depends on the rider and his/her preferences than with other systems. Not regarding the regen modes, EPS states 30 to 70 km (20 to 50 miles) range on one battery charge.
The gearless electric bicycle kit has proven to be absolutely silent. Due to its construction it does not work in combination with a coaster brake or gear hub jet.
It works! And boy does it work - it is fantastic! Thanks very much for all your help in answering my various emails so promptly and helpfully, and of course for sorting out my order.
You can probably understand that I was a little nervous of buying the kit - I am on the other side of the Atlantic and was buying it without being able to try it out. I am delighted to say the BionX kit performs superbly - even the charger!
You may recall that I have a bit of a disability and am recovering from an operation on my leg in April, and am still using a walking stick to walk. Even when I am fully recovered, my knee will only bend to about 90 degrees and my leg will always be weak, so you can see just how useful it is for me to have a electric motor for bicycle - I love cycling and it is the best (just about the only) exercise for my knee and for my leg, but I struggle up hills and into winds.
I did a lot of research into electric bike conversion kits online as well as here in England. I tried out an eBike in the UK which confirmed to me that an electric bike was the way to go, but I didn't like the quality of the bike compared to my existing Trek, and wanted the freedom of a kit so that I could change bikes later if I wanted to. Having tried both, I can say that I made the right decision.
The only kit that seemed to do what I wanted was the BionX PL350: it keeps the bike a bike without adding masses of weight; it gives pedal assist as well as throttle control; the package seemed to be very well thought out indeed as I did not want something that I would have to mess around with to keep working - the list goes on which I am sure you know. However, it was still a step into the unknown for me as I could not try the kit out first but I am delighted to say it fits the bill perfectly, and I do not understand some comments I have read on various forums about it being no good up hills as I can pedal up most of the ones around here (with full assist) in top gear! I think it helps that I and my bike are light and that I have 25mm wide slick tires - maybe those who don't like the kit are very heavy, on heavy mountain bikes with fat tires.
I also tried to research the shops selling the kit - I am sure you can appreciate that I was a little nervous about sending all that money to a shop I had never been to! Luckily, Bionx recommended you to me and various comments on forums echoed that.
Anyway, this is just a long email to say thanks for your help and to congratulate you and Bionx on selling such a fantastic product - I don't think I have ever said that to anyone before about anything, but this really does open up a new world for me as you can appreciate from the links to my website.
Thanks and regards

The Bionx continues to impress me and does just what I need.
I was out on it this morning cycling up and down some hills on maximum assist (up!) or generation (down!) and it cut out on me but maybe it had just got a little hot? The motor was warm to the touch but seemed OK. Anyway, I turned it off for 5 minutes and then it was fine and, the joy of being light, I was able to carry on in the meantime - although it came as a bit of a reminder as to just how much assistance the Bionx gives! I cycled just short of 20 miles in two goes and there's no way I could cycle that distance at the moment without the Bionx.
Everyone who's seen it has been impressed by the neatness of the whole thing, although it's amazing how many people think it can give assistance whilst you cycle along charging it...
Thanks again, Nick
Love my BionX 350W Lithium bike system that your shop installed on 9/24/07. My commute times on the same bike went from 55" to 37" (to work) and from 1'15" to 45" (home). By comparison, my compute to work by car is 27" and 27-35" from work by car. So I am only 10 minutes slower getting to work in the morning with my Bionx. In the evening I am only 10-15" slower getting home. This reduction in time makes the bicycle a much more appealing commuting tool especially in this hectic tristate area.
After looking into getting an electric motor for bicycle for more than 4 months, I am glad that I decided on the BionX motor kit, it is really great. Thank you very much for your advise. I still get a great cardiovascular workout with the Bionx but the hills (very hilly section of New Jersey) are less brutal.

I think there are two kinds of people who are interested in converting their bicycles to use electric power. First, there are the technology lovers who cannot get enough gizmos to mount on their handlebars, and who could never be fulfilled by all the spec sheets a bike shop could offer. Then there are the rest of us, who couldn't tell a volt from a watt if our life depended on it. Of the latter category, I think many see the wonderful potential in having an electric bike--its energy efficiency is astounding, and it allows many to travel to places they wouldn't or couldn't otherwise.
However, it can be frustrating for the non-tech-savvy to compare the detailed differences between different electric conversion systems. Since we here at NYCeWheels want to help you get the exact product that is best for you, I thought I'd break down what you get with each of the BionX systems, and what the different wattage and voltage ratings for each mean for you as a practical user.
The entry level PL250 BionX kit includes a 250-watt motor and a 24-volt battery. Since the more expensive kits use 350-watt motors, and 36- or even 48-volt batteries, many people assume that these kits will always be "better". And it's true, all other things being equal, the PL350 and SL350 kits are more powerful and would be faster--if it weren't for the fact that all BionX kits top out at about 20mph by design. For legal reasons, electric bike conversion kits tend to be governed at 20mph, since above these speeds the vehicles would no longer by considered simple "bicycles", and would require further licensing.
What the increased wattage and voltage does get you, however, is increased power. Practically speaking, this translates into better acceleration and the ability to more easily tow large loads of heavy cargo. Thus, anyone looking for an electric conversion kit to help ascend steep hills, or pull trailers would do well to invest in the higher-level BionX conversion kits.
That said, there are still some other practical advantages to the humble PL250 kit. Due to its smaller battery capacity and stripped down motor, it is the lightest of the three BionX conversion kits. But before you jump to the conclusion that a smaller battery capacity will limit the range of a bike equipped with the PL250, bear in mind that the 250-watt motor requires less power to operate, which helps to conserve battery life. The result is that the BionX PL250 kit achieves a similar range per charge as do its larger cousins with bigger batteries--all while keeping to a svelte 16lb package.
So, to summarize, the PL250:
Meanwhile, the PL350:
Finally, the SL350:
Hopefully that should answer some of the basic questions you have about BionX kits. Now that you know which conversion system is right for you, head over to the BionX page and order yours today!
