SKU: 040884-04-700 Categories: ,

Bionx-rc3-console_bikeThe P350 DL is a long-range Bionx system with a lithium battery battery supplies 317 Wh, providing up to 50 miles on a single battery charge. The Bionx P350 motor includes a cassette body that fits SRAM or Shimano 6 to 10 speed cassettes.

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.

The P350 DL 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 to recharge.

And if you’re riding down a steep hill and want 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.
