Description:
Speed ​​tuning chip is an excellent solution to remove the speed limitation to 25 km/h for E-bikes.
This chip allows you to use the bike to its maximum potential and go at higher speeds with full support from the engine.
The chip is small and easy to connect, so it requires a small installation space.
The connection is simple and cannot be connected incorrectly. Remove the male plug of the sensor from the engine, insert it into the transparent female part of the chip, pressing it as hard as possible until the pins are fully inserted, and the male plug of the chip is inserted into the engine, so the chip is inserted between the engine and the speed sensor . The chip can be easily removed and cannot be detected by the bike's diagnostic system because it simulates a normal bike behavior.
During installation, the plugs must be pressed very well until a muffled click is heard, otherwise the operation may be intermittent and the warning for the speed sensor may appear, check that the plugs are well pressed and restart the bike.
