BionX Electric Bike Motor Conversion Kit
BionX Electric Bike Motors Make you feel like the Bionic man!
In early 2012 we stopped selling BionX
electric kits due to new US regulations requiring DOT hazardous
materials certification to ship the lithium batteries. Their
warranty return rate continues to be high enough that we feel we
should not sell the product if we cannot return the batteries to the
factory for warranty replacement or repair. BionX kits are a joy to
ride when they are working and BionX continues to work on
reliability improvements, we wish them well. The rest of this page
is left here for informational purposes.
Is getting up those hill getting you down? Do you find the ride to
work to long and time consuming? Don’t want to arrive sweaty at
work? Family members can’t keep up on group rides? Maybe the BionX
electric bicycle motor assist is the answer for you. Spelled BionX
and pronounced bionix (bionics) ~ The BionX converts your bike into
a lightweight rechargeable electric bike.
Made in Ontario, Canada the BionX electric bike motor conversion
kits are high tech, easy to control and lightweight. We stock their
top of the line PL 350 system. It features Lithium Ion batteries for
light weight and long life and a 350 watt motor to add a significant
boost and flatten those hills! It even has regenerative braking
(like a hybrid electric car) to charge your battery while saving
your brakes on down hills! We keep a recumbent in the shop ready to
ride set up with the BionX electric bicycle motor, come give it a
try and test ride it!

BionX is light, compact and easy to install on
To test the BionX system I used a Sun Sport CX recumbent bike outfitted with
a BionX P-250. I used the motor like this; on hill climbs I set it on full
assist. On larger down hills I pedaled lightly and whenever the bike
exceeded 20 mph I used the regenerative brakes to recharge the battery.
My BionX electric bike battery range test ride:
I rode from our shop to Wegman's in Hornell, a 20 mile round trip and
returned a movie rental. I took the hilly rout both ways, over Pennsylvania
Hill Road. This adding a few climbs on the way out and a huge climb and a
few smaller ones on the way back. Total climb on this ride was nearly 1000
vertical feet, I did not measure this accurately. I set the BionX on full
boost and pedaled at my normal, pretty vigorous rate. It was March so I was
not in the shape I'd be in midsummer. When the bike went over ~20 MPH I set
the BionX to slow the bike and recharge the batteries. This kept my speed
under ~25 mph on all but the one big decent – Pennsylvania Hill. On the way
down Pennsylvania hill even recharging the batteries it went up to nearly 30
MPH. I didn’t use the brakes but could have easily stopped if I’d wanted to.
Without the BionX the bike would have gone nearly 50 mph on this decent.
This very hilly 20 mile ride took me 1 hour, 15 minutes, a 16 mph average
speed. Without the BionX this course would have taken me at least a half an
hour longer and been more tiring. Climbing Pennsylvania Hill without the
BionX would have been a strain on the heavy Sun EZ-Sport. Even on a racing
recumbent it would have been hard work on this hilly course. When I got home
the battery was nearly used up but I could still feel the boost of the motor
as I pulled in the driveway.
I went 20 miles on
a charge, some riders may go farther per charge, some may get fewer miles
per charge. It depends on what level boost you use and how hilly your rides
are. BionX claims a range of 20 kilometers (15 miles) which is probably
closer to what most riders will get. It is better to plan on the 15 mile
range between charges, especially for larger riders and those who may be a
bit out of shape.
The 250 watt motor flattened the hills even on the Sun, which is not a light
bike or known as a great climber. The next day, after a recharge, I tried
the P-250 on the Hartsville Hill climb (1.5 miles, 425 vertical feet) and
was surprised how easy that killer hill was.
If you are more sparing in its use or riding on less hilly roads the
BionX will have a greater range on one charge.
The BionX assists you up to about 20 mph, over 20 mph you are on
It is very noticeable on hill climbs, not so noticeable on flat
It will be more noticeable for smaller lighter riders, less
noticeable for larger heavier riders. Larger riders may want to
consider the 350 watt version. (This test was the standard 250 watt
The controls are really easy to get used to and give good
information: battery condition, current speed, current boost or
recharge rate and boost or recharge setting selected. In 2009 BionX
improved their systems with more robust electronics and quieter
Recharging the battery on down hills helps control your speed and
extend my range. On flat roads this is not significant.
With a BionX your bike is still light enough (~55 lb total) you can
still finish a ride even with the battery flat without killing
Note: We do not recommend changing any settings except for the ones
found in your BionX owners manual.
Benefits of the BionX electric motor bike system:

Lithium Ion battery
We currently stock the PL-350 with a Lithium Ion battery which adds ~20% to
Providing a higher torque, this model is the best in class for climbing,
long rides and fast accelerations. Providing a quicker and higher % of
assistance than the PL250. Outfitted with a down tube battery mounting unit
or on a new and practical rear rack version, to suit all frames and riders.

About our BionX battery electric test bike.
We used the Sun EZ-Sport as out electric recumbent for several reasons:
It is comfy,
easy to get used to, inexpensive and fits a wide range of riders.
It is not light
or fast, features not required for a BionX test bike.
Note: We do not recommend changing any settings except
for the ones found in your BionX owners manual.
It makes a comfy but pretty mundane bike fun!
And the BionX isn't just for recumbent bikes

Just wanted to say
thank-you for sending over the kit. It works really well
and I have attached a few photos so you can have a look.
