What is SpeedFun Furious?

SpeedFun FURIOUS is an electronic and intelligent speed release device that requires no external power supply.

It is designed for Impulse engines to evade the speed block at 25 kmH, allowing it to increase its active assistance up to a speed of 50 KmH, making full use of the potential of the excellent Impulse engine.

Speedup FURIOUS can be mounted very simply by interposing it between the speed sensor and the motor using original connectors that do not alter the characteristics of electrical resistance and water tightness. It does not modify the Impulse engine electronics, which can be reset at any time and in a few minutes to the factory configuration.

This allows the guarantee and the effective commercial value of the bicycle to remain unchanged.

Once the Furious Easy device is installed, the bicycle tachograph will show half speed and relative data making it possible, by simply multiplying by two, the calculation of the actual speed and kilometers traveled.

Furious for Impulse is available in two versions:

– EASY version For IMPULSE 1 motor: from the moment of installation the device is working, always active, not deactivable.

– EASY version For IMPULSE 2, IMPULSE 2 EVO and IMPULSE 2 EVO RS motors: from the moment of installation the device is working, always active, can not be deactivated.
