POLINI Hi-Speed E-Bike Yamaha PW/PWX/Syncdrive Pro

Polini Hi-Speed is an electronic device studied for E-bike motors with the aim to increase the pedal assist mode exploiting at all the performance that the motor can offer. The assembly takes only a few minutes. It does not require any setting because it is self-adjusting. The device does not require any battery since it is self-recharging.
The speedometer will always show half of the actual speed, and the same for the Kms travelled. To know speed and kms travelled it is enough to double the figures.
