What is the SpeedFun Furious Evo tuning for Bosch Performance Line SX (gen. 4) Smart System – Rim Magnet?

The function of the Furious Evo tuning device for Bosch Smart System is to electronically manipulate the rear wheel rotation speed and communicate to the motor a speed always below 25 KmH in order to achieve a very high real speed with the motor active. The maximum speed limit will therefore be dictated by the motor power added to the power expressed by your own legs.

When the device is active, the display will show the exact speed up to a threshold of about 20 KmH, beyond which a manipulated speed always below 25 KmH will be shown.

This speed unlocking device is compatible only and exclusively with Bosch Performance Line SX (gen.4) 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, Purion 400 or System Controller + Mini Remote) or Purion 200.

SpeedFun Furious Evo comes ready to use, plug and go, can be activated and deactivated at will, and retains the setting even after the ebike is turned off. It can be easily installed thanks to compatible connectors.

The kit includes all the necessary elements for installation, ensuring extremely easy assembly.

All these components have been specially designed and manufactured by us to ensure correct placement of the parts during installation and to avoid malfunctions over time or issues during your rides.

Since these parts are made internally by our company, they have been specifically designed to best fit the Bosch Performance Line SX (gen. 4) Smart System motor.

WARNING!
This device is not compatible with ebikes equipped with a “classic” magnet on the spokes or brake disc.
This device is not compatible with ebikes equipped with Bosch ABS system.
This device is not compatible with ebikes equipped with GPS system (Bosch ConnectModule).
