Main Product Information
The function of the Furious Evo tuning device for Ananda M60 M81 M100 M230 and Atala AM80 Agile (Gen. 2) 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 very high real 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 your legs.
The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:
Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]
IMPORTANT Activation and deactivation:
- Turn the ebike off and on again. Do not move it or do other operations.
- Raise the rear wheel, give a strong pedal with the longest (hardest) gear engaged. Let it run for a few seconds.
- The system recognizes the acceleration and considers it as an activation or deactivation command (cyclically). Upon activation, the display shows the speed that change from real to halved in the manner described above. When deactivated, the display shows the speed change from halved to real and the bike returns to its original state.
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 ebikes with Ananda M60 M81 M100 M230 and Atala AM80 Agile (Gen. 2) motors mounted mostly on Olympia ebikes (in this case often with the wording “Tuned by Olympia”) regardless of the type of display or side control of the ebike.
