There are a variety of different tuning chips available for the Bosch Gen 4 motor. A tuning chip essentially removes the 25km/h speed restriction on your eBike and allows you to continue to pedal with assistance from your Performance Line CX motor. However, for those of us that want to be able to ride a bit faster, you will need a tuning chip.
For many, 25km/h is enough speed for an eBike. However, despite all the power the 25km/h speed restriction will kick in, meaning that on the flat terrain you will be pedalling against the motor, unable to go any faster. The Gen 4 motor is extremely powerful - it will tackle the steepest climb with ease. This particular motor is the most popular for eBikes in 2021 & 2022 with the likes of Cube, Cannondale & Whyte choosing it as their motor of choice for their eBikes. The Gen 4 Performance Line CX motor was released in 2020 and is Bosch's motor powerful eBike motor to date providing 85nm of torque. Before we start, please note that removing the speed limit on your eBike can void your warranty, eBikes with the speed restriction removed are illegal and only to be used on private land. We will also discuss the best tuning chips for the new Bosch Smart System eBikes released in 2022.
