Main Product Information

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 SX (gen.4) 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.

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]

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.

This speed release device is compatible only and exclusively with Bosch Performance Line SX (gen.4) 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.

ATTENTION!
This device is not compatible with ebikes equipped with a “classic” magnet on the spokes or brake disc.
This device is not compatible with ebikes equipped with the Bosch ABS system.
This device is not compatible with ebikes equipped with a GPS system (Bosch ConnectModule).
