The Bionx lightweight HT-Motor rear hub motor/generator is noise and vibration free.

High Speed settings up to 28 mph are available. Class 2 (20 mph pedal-assist with throttle) or Class 3 (28 mph pedal-assist only) settings are available for Bionx electric bike conversion kits.  Class 3 settings are currently available to residents of California, Utah, Colorado, Arkansas, Illinois and Tennessee.

Bionx-rc3-console_bikeThe P350 DX is a long-range Bionx system with a lithium battery battery supplies 423 Wh, providing up to 65 miles on a single battery charge. The Bionx P350 motor includes a cassette body that fits SRAM or Shimano 7 to 10 speed cassettes.

The P350 DX features a compact Bionx RC3 controller with a throttle and full functionality that can operate the bike alone or be paired with an optional Bionx DS3 Display (not included).

All Bionx systems feature Regenerative Braking, so when you squeeze your bike‘s brake lever, energy is sent back to the Li-Ion batteries, helping them recharge.

And if you are riding down a steep hill and want some extra braking or a greater workout as you pedal, switch the Bionx system into one of its four Generate Mode levels. You’ll feel resistance, and even more energy is returned to the battery pack – a feature only available with Bionx hub motors.
