Motor class switching

Select Rad Power Bikes models offer motor class switching to allow you to select a motor class for your ebike that best suits your needs. Motor class switching is available on the following models with color displays:

  • Radster Road
  • Radster Trail
  • RadWagon 5
  • RadExpand 5 Plus

To change the motor class setting while the ebike is stopped, navigate to the Menus screen and select the 'Class' menu, and then use the remote buttons to select the class setting most appropriate for you. Once a new class is selected, it will default when the ebike is powered on.

Class Top Speed Throttle Notes
Class 1 20 MPH (32 KM/H) Limited This class allows the ebike to receive motor assistance up to 20 MPH (32 KM/H) while pedaling. Throttle functionality is limited to only when the ebike is being pedaled.

Select this class if you want to limit accidental throttle activation, or if want to conserve battery power by limiting throttle usage.
