What is SpeedFun Furious Evo for Five F90 ebike tuning?

The function of the Furious Evo tuning device for Five F90 is to electronically manipulate the rotation speed of the rear wheel and to communicate to the motor a speed always lower than 25 KmH in order to obtain a real speed with very high active motor. The maximum speed limit will therefore be dictated by the power of the engine added to the power expressed by one’s legs (info).

When the tuning device is active, having no communication with the display, it will show the halved data on the display starting from a certain threshold.

SpeedFun Furious Evo can be activated and deactivated at will and maintains the setting even after the ebike is turned off. It can be installed on ebike with Five F90 motors mounted mostly on Italwin ebike and many others regardless of the type of display or side control of the ebike.

The Furiosu Evo tuning device for Fazua can be activated/deactivated by simply pressing the ebike’s light button. If the ebike already has the lights connected to the light output, or if it is not possible to use it, it will still be possible to activate/deactivate the tuning with a very practical system (for more information see the instructions here). The device is supplied plug and go ready to use and is installed in a very simple way thanks to the original connectors with which no physical modification of the ebike is necessary.
