bionx_d_500_bike_motor_kitAbout the Bionx D500 Motor System
The Bionx D500 motor is a powerful animal and totally silent. A radical new take on the bicycle hub motor, the Bionx D series motors are flatter and thinner that traditional hub motors and fits neatly between the wheel spokes providing more wheel flex for greater grip and traction.

Add a very large 48 volt ~11.5 ah (555 watt hour) battery and you’ve got the mother of all conversions kits with loads of torque, silent hill-climbing power and a range of up to 80 miles.
