Power module POLINI HI-SPEED for Shimano EP8 e-bike

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. This allows the available power to be fully used again.
Very easy to install since the connectors interface with the original ones while maintaining the waterproof feature. The waterproof plugs fit directly onto the original plugs. Installation takes only a few minutes without having to open the engine or remove the original seals. The device is completely invisible because it is housed inside the engine crankcase. It is completely reversible, allowing you to quickly return to the original configuration. If the limitation is removed with the POLINI HI-SPEED tuning module, the speedometer shows only half the actual speed. To determine the actual speed, the displayed value must therefore be doubled.
Not suitable for electronic Shimano Di2 gear shifting!
