Electrical box Hi-Speed Yamaha PW-X3

The POLINI HI-Speed kit is an electronic device designed for electric bikes equipped with the YAMAHA PW-X3 motor.

This kit allows for an increase in active assistance and maximises the performance that the motor can offer.
Installation can be done easily in just a few minutes without any special technical skills.
The connectors slot directly in with the original ones, preserving their optimal water resistance capabilities.
This kit is completely invisible and fits naturally inside the frame or the designated motor compartment.
Totally reversible, the original setup can be easily restored by unplugging the kit.
The kit requires no adjustments afterwards as it self-regulates, and an external power supply like a battery is not necessary since it powers itself independently.
