Frequently Asked Questions

After the Tuning kit is installed, your e-bike will be derestricted and you will reach maximum speed!

After installing your SpeedFun, your e-bike’s display will show real data up to 12mph (20km/h) - at higher speeds, the display will show half speed and relative data making it possible, by simply multiplying in mind by two, the calculation of the actual speed and miles or kilometers traveled.

After installation, your tuning kit will be activated with the activation of your eBike. Maximum speeds of ~30mph (50km/h) or even faster can be expected, depending on the bike and gearing.

The new technology of this tuning module for Shimano does not require the activation of the motor's light output or interventions with diagnostics or apps. It is supplied ready to use with plug-and-play connectors, no physical modification of the ebike is necessary.

PLEASE NOTE: This tuning is not compatible with ebikes equipped with Shimano Di2 electronic derailleur.

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 locked in the manner described above. When deactivated, the display shows the speed change from locked to real and the bike returns to its original state.

This tuning kit is specially designed for Shimano Ep8 motors with mechanical gearing (no DI2). It can be installed on e-bikes with any type of display or side control as well as on e-bikes without a display or that mount the EW-EN100 wireless module.
