35a controller Rad


New version 35a controller with tail light feature!  Looking for more power, acceleration and torque for your Rad bike? Introducing our new 35a controller upgrade plug and play to the Rad bikes. Instantly take your bike to a whole new level of performance you've been dying for. This 35a controller will also work on the Rad Mini and can be installed on the down tube (see photo).

*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.

Dimensions are 7.2 x 3.2 x 1.7in.  This controller is required to be use with our color display KT-LCD8H. You can NOT use the Rad's LCD display with our controllers and vice versa.
