power module / dongle Polini Hi-Speed for e-bike (pedelec) with Shimano EP8 motor

Polini E-bike tuning module for Pedelec with Shimano EP8 Motor.

With the POLINI HI-SPEED module, the 25km/h pedal assistance speed limit is raised to 50km/h. It can thus be completely retrieved the available power again.

Very easy to install since the connectors interface with the original ones maintaining the waterproof feature. The waterproof plugs fit directly onto the original plugs. The installation takes only a few minutes without having to open the engine or without removing the original seals. The devise is completely invisible because it is housed in the interior space of the engine crankcase. It is completely reversible and you can return to the original configuration in a rush. If the limitation is removed with the POLINI HI-SPEED tuning module, the speedometer shows only half the speed. So to determine the actual speed, the read value must be doubled.

Not suitable for electronic Shimano Di2 gear shift!
