What is SpeedFun Furious Evo tuning for Bosch Performance Line CX Smart System – Rim Magnet?
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 engine a speed that is always lower than 25 KmH in order to obtain a very high real speed with the engine active. The maximum speed limit will therefore be dictated by the power of the engine added to the power expressed by your legs ( info ).
When the device is active, the display will show the exact speed up to a threshold of approximately 20 km/h, beyond which a manipulated speed of always less than 25 km/h will be shown.
This speed release device is compatible only and exclusively with Bosch Performance Line CX and Performance Line CX Race Limited Edition (gen.4 BES3) motors equipped with a valve magnet (Bosch Rim Magnet) with LED Remote/System Controller control (also compatible with Led Remote + Kiox 300/500, Intuvia 100 or System Controller + Mini Remote) or Purion 200.
The Bosch Speed Unlock Rim Magnet kit includes all the elements necessary for installation, thus ensuring extreme ease of assembly.
All these elements have been specifically designed and created by us to ensure correct positioning of the parts during installation and to avoid malfunctions over time or inconveniences during your outings.
Since these parts are made internally by our company, they have been specifically designed to best fit the Bosch Performance Line CX (gen.4 BES3) Smart System engine.
