The novelty of the HI-Speed 2 version is the display of the actual speed. The previous version showed the speed divided by 2.
Unfortunately the travelled distance is still showed divided by 2.

The Polini Hi-Speed E-Bike module is an electronic device developed for e-bike engines with the aim to evade the 25Km/h limiter and make the pedal assist mode to remain activate up to 50 km/h, exploiting all the performance that the engine can offer.
The Polini Hi-Speed module is very easy to install since the connectors match with the original ones, therefore the waterproof feature remains intact.
The assembly takes only a few minutes without opening the engine and without removing the original seals. The device is completely invisible because it is housed in the interior space of the engine crankcase.
The installation is completely reversible and you can return to the original configuration in a rush.
It does not require any setting because it is self-adjusting.
No battery is needed since it is self-recharging.
It can be easily discontented by unplugging the magneto placed outside the engine.

It can be adapted to the Bosch engines: it is available in two different models, one for the Classic+ version and one for the Active Line and Performance Line versions.

*** If changing the speed settings form 25 to 50 does not work you can try to press the WALK button and + button two times, so: WALK > + > WALK > + ***
