    What does this Tuning Kit do?

    SpeedFun Furious Evo easy + is a tuning for ebike equipped with a Bosch Smart System motor that allows you to remove the 25 km/h speed block.

    This speed release device is compatible only and exclusively with Bosch Performance Line, Active Line and Active Line Plus (gen. 3) motors equipped with a magnet on the valve (Bosch Rim Magnet) with LED Remote/System Controller command (also compatible with Led Remote + Kiox 300/500, Intuvia 100, Purion 400 or System Controller + Mini Remote) or Purion 200.

    Achievable speed

    Calculate your speed

    The achievable speed mostly depends on the eBike model. Enter your own values:

    Speed 37.5 km/h

    Theoretical value from cadence and gearing only. Your real speed also depends on the motor, the tuning kit, the rider and the terrain.

    Speed = cadence [rpm] × wheel circumference [mm] × front chainring teeth ÷ rear sprocket teeth × 60 [min/h] ÷ 1,000,000 [mm/km]

    How to install this Tuning kit?

    When connecting Tuning Kit to an e-bike you will find connectors colored to make installation very simple. We have prepared detailed instructions to make installation easy for you. Disassembly of our tuning kit is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us. If you are planning to install Speedfun on a brand-new bike, make sure you ride it for at least 0.6 miles (1 km) before the tuning kit is activated.

    FAQ & legal

    How does Speedfun work?
    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]

    Note:
    - It is supplied ready to use in "ALWAYS ON" mode and cannot be deactivated.
    - If you want to be able to activate and deactivate the speed release function, you need to cut/interrupt the jumper at the point indicated by the arrow (insulate both ends!). There is no way back after this. Read the activation and deactivation methods on the instructions.

    Activation:
    - Turn Off the ebike.
    - Place the chain on the longest gear (the smallest rear sprocket).
    - 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.
