What is SpeedFun Furious Evo tuning for Bosch Smart System?
The function of the Furious Evo tuning device for Bosch Smart System is to electronically manipulate the rotation speed of the rear wheel and to communicate to the motor a speed always lower than 25 KmH in order to obtain a real speed with a very high active motor. The maximum speed limit will therefore be dictated by the power of the engine added to the power expressed by one’s legs.
This speed release device is compatible only and exclusively with Bosch Performance Line SX BDU3144 / BDU3145 motors equipped with a magnet on the valve (Bosch Rim Magnet) with LED Remote/System Controller command (also compatible with Led Remote + Kiox 300/500, Intuvia 100 or System Controller + Mini Remote) or Purion 200.
When the device is active, the display will show the exact speed up to the threshold of about 20 KmH, beyond which a manipulated speed will always be shown below 25 KmH.
SpeedFun Furious Evo is supplied ready to use, plug and go, can be activated and deactivated at will and maintains the setting even after the ebike is turned off. It can be installed easily thanks to the compatible connectors.
