25a Controller for Rad Ebikes


Our new upgrade 25 controller for the Rad Ebikes will give you a 50% power increase from stock! It is plug and play to the Rad bikes and comes with tail light features.

*Please note when plugging the motor to the controller, you MUST push both motor plugs together as hard as you can. Use a lot of force to push them together until you feel a click to secure it. If this connection is not secure, you will get error message on the display screen. A loose connection could also cause heat and melt the wire and plugs.

This 25a controller has to be use with our KT-LCD8H display or KT-LCD3/usb display. You can NOT use the Rad's display with our controllers and vice versa. Links to our LCD's are below:
