power module / dongle Polini HI-SPEED 2 for E-bike w/ Bosch Performance Line MY20

With the POLINI HI-SPEED 2 module the speed limit of the pedal assistance is raised from 25km/h to 50km/h. The available power can thus be completely called up again.

The installation is very easy, 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 Polini Hi-Speed 2 dongle is invisibly installed into the crankcase. It is completely reversible and you can return to the original configuration in a rush.

Pressing the Walk Button (approx. 2 seconds) activates or deactivates the speed lock. In contrast to the first Polini Hi-Speed tuning module generation, this new type always shows the real speed!

Suitable for Bosch Performance Line MY20 drive.
