With the POLINI HIGH-SPEED power module, the limit of the speed assist is raised from 25kph to 50kph. This device releases the limiter and gives you all the available power on tap. Installation is easy, the waterproof plugs fit directly onto the original plug. The installation takes only a few minutes, without having to open the engine or remove the original seal. The device is completely invisible mounted inside the motor housing. Removal is simple and without residue. The magnets attached to the motor release the speed restriction. If the magnet is removed, the pedelec is again limited to 25kph. If the limit is lifted with the POLINI HI-SPEED tuning module, the speedometer indicates only at half speed. So, to determine the actual speed, the reading must be doubled.
