This device is designed for e-bikes in order to remove the speed restrictor of the engine set at 25 Km/h and consequently to maintain the assistance up to 50 Km/h, fully exploiting the performance that the engine can provide. Installation is done without opening the engine, without the help of a power supply, nor the unsealing of any original parts; Additionally it is totally invisible as it is housed inside the motor casing.
Equipped with sealed connectors, the unlocking of the engine from 25 km/h is activated and set with the computerised-on board controller. The speedometer will always show the correct speed.
You can activate / deactivate the unlocker using the walk button that is the factory setting; you can change this choice using lights or the reset button.
