Bosch Gen1 Tuning without Chip
Unlock Your Bosch Gen1 Classic+ Motor
Bring New Life to Your Classic E-Bike
The Bosch Gen1 Classic+ motor is where the e-bike revolution truly began. Known for its robust performance and reliability, this early system still powers many bikes today. However, the standard 25 km/h (15.5 mph) speed limit can feel restrictive — especially with modern riding expectations.
With the EBT Unlock Key, you can safely and conveniently unlock your Bosch Classic+ motor and enjoy a freer, more dynamic riding experience — while preserving the originality of your classic e-bike.
About the Bosch Gen1 Classic+ Motor
First released around 2011, the Bosch Classic+ motor established the foundation for Bosch's success in the e-bike sector. Key features include:
- Strong and durable motor construction
- Reliable pedal support for city and touring bikes
- Maximum torque of around 50 Nm
- Paired with either HMI or Intuvia displays
Although the motor remains extremely reliable, the preset 25 km/h limit can be a limiting factor, especially for longer rides or downhill sections. Unlocking the Classic+ system revitalizes your e-bike experience without hardware modifications.
Important Compatibility Notes: HMI vs Intuvia Display
- HMI Display: Unlocking works perfectly, but after unlocking, speed and distance values may not display correctly on the screen.
- Intuvia Display: Unlocking works perfectly, and all speed and distance values are displayed correctly.
Regardless of the display type, the EBT Unlock Key ensures your motor's performance is fully unleashed, while leaving the motor hardware untouched.
