SpeedFun Furious Evo easy+ for Dapu MD250S motors

The function of the Furious Evo tuning device for Dapu MD250S 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 motor added to the power expressed by one’s legs.

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. Compatible with Dapu MD250S motor mainly used by Cortina, Ekletta and many other.

The Furiosu Evo for Dapu MD250S tuning device can be activated/deactivated in a very practical system (for more information see the instructions).

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]

After installation, your tuning kit will be activated with the activation of your eBike. This tuning kit can be activated / deactivated also, but only by your choice, you do not need to do it everytime you turn on ebike.

IMPORTANT Activation and deactivation:
- Turn Off the ebike.
- Place the chain on the longest gear (the smallest rear sprocket).v - Position the left pedal at 11.00. From now on, do not turn the rear wheel.
- Turn On the ebike and wait for the complete check. Don't spin the rear wheel (not yet ..).
- Raise the rear wheel, give a strong pedal. Let the wheel spin over 30 km/h for a few seconds.
The system recognizes the acceleration and considers it as a command to activate or deactivate (cyclically) the speed release. Upon activation, the display (if present) shows the speed that passes from real to manipulated in the manner described above. When deactivated, the display shows the speed change from manipulated to real and the bike returns to its original condition.

SpeedFun Furious Evo can be activated and deactivated at will and maintains the setting even after the ebike is turned off. Compatible with Dapu MD250S motor mainly used by Cortina, Ekletta and many other.
