This SpeedFun Furious is a tuning kit for eBikes powered by a Bosch Performance Line CX (Gen4) motor + Rim Magnet Sensor. It also works with Race edition Gen4 motors.

Once fitted, it will remove the factory 15mph or 20mph speed limit. Derestricting the bike fully. 

Speedfun works with eBikes fitted with or without a display. 

It's fully tested on the latest 13.13 Bosch update and comes with a 1-year warranty.   

Important, please read before purchasing

This is a moderate to hard installation (see product images). The kit comes with 3 components; tuning module, replacement speed sensor & electromagnet unit. Some bikes will require the motor to be dropped down in order to fix the electromagnet. The OEM speed sensor is removed and replaced with a wired sensor fixed to the chainstay.

If you are not comfortable handling your bike's motor, you should seek a professional for help with the installation. 

Once your order is placed, we will contact you on email for a compatibility check.
