Main Product Information

Tuning module for the Bosch Smart System. Compatible with all Bosch drive systems that are equipped with the Smart System and whose motor support ends at 25km/h (15.5mph) from the factory. Note: Bikes with rim magnet and ABS systems are not supported

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]

- 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 tuning kit is compatible with Bosch Smart System. Bikes equipped with a rim magnet are not supported by the tuning. Not compatible with with e-bikes with Bosch ABS system as well. The Smart System is most easily identified by the Intuvia 100 or Kiox 300 display type or the LED Remote control unit or the system controller.

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.
