NEW FOR 2015: Powerful D-series kits DV and DX--stay tuned for more, or call today to order for late November.

S350 DL (D = down-tube) and RL (R = rear rack) with 48V 6.6Ah Battery
This model boasts a long-range (up to 50 miles), more efficient, lighter-weight battery. Showing how far the industry has come, the Lithium-ion 48V battery on this system provides over twice the amount of energy contained in the 24V NiMH battery, the battery first featured when electric bikes appeared on the scene--commercialized by BionX in 2003.
Installs on the front down tube using the water bottle mounts. DL = black components with low-profile battery. RL system, in black only, installs with the custom BionX rear rack as below right. Additional $100 for rear rack.


S350 DX (D = down-tube) and RX (R = rear rack) with 48V 8.8Ah Battery
This kit delivers more power, more quickly, with its 48 volt battery and super-lightweight motor. All S350 X available in silver only. 
The S350 kit is available in both standard (DX) and rear rack (RX). Additional $100 for rear rack; example pictured below.

Rear Rack Model PL350 HT RR M
This PL350 motor has been the workhorse of the BionX line since its release in 2009 with high-torque silent Sin-drive motor great for hill-climbing. Still a good range (37 mi!) compared to other e-bike kits, and always with BionX quality, efficiency and regeneration. This kit is available only with the BionX custom rear rack pictured at lower right in black or silver components (no down-tube version). Includes a built-in rear safety light and port for optional front light or accessory wiring.

G2 Console
The G2 (pictured here) console is ergonomic and removable--providing a separate toggle-on throttle and power control for mounting next to either left or right hand grip. And a comprehensive multi-functional easy-to-read display also adaptable to left or right hand use.
