How SpeedFun was born!

The 25 km/h limit, above which the assisted-pedalling electric device is deactivated, was, up
to today, an insurmountable obstacle for bicycles equipped with BOSCH servomotors, given
they meet the restrictions set by European regulations.

SpeedFun was born from a simple idea by its inventors, who realised that a mechanical
override could trick the electronics of the motor and, thereby, slow down the frequency
detected by the sensor on the wheel, by which the motor determines the speed of the bike
and, therefore, whether to cancel assisted pedalling or not.
