E-bike tuning module POLINI HI-SPEED for Shimano Steps Motor

Polini Hi-Speed is an electronic device designed for E-bike motors to bypass the 25km/h limiter and consequently increase the pedal-assist mode, which remains activated up to 50km/h, taking full advantage of the performance the motor can offer.
Polini Hi-Speed is very easy to install because the connectors interface with the original ones while maintaining the waterproof feature. Installation takes only a few minutes without opening the motor or removing the original seals, and the device is completely invisible because it is housed inside the motor crankcase. It is completely reversible, allowing you to quickly return to the original configuration. No settings are required because it is self-adjusting. No battery is needed because it is self-recharging.
Not suitable for electronic Shimano Di2 gear shifting!
