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 (Class 1 and 2 only)
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.
