Bosch Gen4 Tuning without Software

Unlock Your Bosch Gen4 Performance Line CX Motor

Ride Beyond Limits

The Bosch Gen4 Performance Line CX motor is renowned for its impressive torque, lightweight design, and dynamic support on any terrain. However, its factory speed limit of 25 km/h (15.5 mph) often restricts the full potential of your e-bike. With the EBT Unlock Key, you can unlock your Bosch Gen4 motor safely, discreetly, and without any physical modifications to your bike.

Our web-based software solution is designed for riders who seek true freedom and want to experience their e-bike as it was meant to be — powerful, fast, and unrestricted.


About the Bosch Gen4 Motor

Introduced in 2019, the Bosch Gen4 Performance Line CX motor quickly became the standard for high-performance eMTBs and trekking bikes. Key features include:

  • Maximum torque of 85 Nm
  • Compact and lightweight build
  • Optimized for off-road and trail riding
  • Advanced eMTB mode for intelligent assistance
  • Standard speed restriction of 25 km/h (15.5 mph)

Despite its capabilities, the speed limit can often be a frustrating limitation, especially on open roads or downhill tracks where the motor assistance cuts off abruptly. Unlocking your Bosch Gen4 motor allows you to enjoy a more natural and continuous riding experience.
