If you make bikes, now you can make eBikes...

The Revolutionworks RW250 powertrain consists of a hub motor, motor controller, with integral pedal assist sensor (PAS), rechargeable battery, and a handlebar control and display. RW250 can be easily fitted to your bike design to produce an ebike with excellent power characteristics. The RW250 powertrain complies with UK/EU requirements for electric pedal-assisted cycles (EPACs). It will provide electric assist up to 15.5mph as long as the rider keeps pedalling. Pedal assist can be on for the whole trip or switched off at any time, or one of three power levels can be selected on the handlebar control. The handlebar display shows the state of battery charge and which power level is selected. The RW250 is engineered in the United Kingdom.
