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's rotation speed and to communicate to the motor a speed always below 25 KmH in order to achieve a very high actual speed with the motor active. The maximum speed limit will therefore be dictated by the power of the motor added to the power expressed by one's own legs (info).

"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 will always be shown as less than 25 KmH."

This speed unlock 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 (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 turned on and off at will, and retains the setting even after the e-bike is turned off. It can be easily installed thanks to the compatible connectors.

The kit includes all the necessary elements for installation, thus ensuring extreme ease of assembly.

All these elements have been specifically studied and created by us to ensure a correct placement of the parts during installation phases and to avoid malfunctions over time or inconveniences during your outings.

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

This device is not compatible with ebikes equipped with a "classic" magnet on the spokes or on the brake disc (see here).
