EBT Unlock Key – 2 Licenses for Bosch Gen1–Gen4
(except Bosch Gen1 HMI and Smart System)
Two licences, two bikes, one browser-based unlocking solution.
This 2-license package is ideal for riders with two compatible Bosch e-bikes, for couples, friends, workshops or anyone managing more than one bike. The EBT Unlock Key removes the factory 25 km/h speed limit on compatible Bosch systems – fully browser-based, with no software installation, no chip, no dongle and no motor disassembly.
Each licence is intended for one compatible bike and works independently. The solution supports many Bosch Gen1, Gen2, Gen3 and Gen4 e-bikes based on BES1 / BES2. It is not compatible with Bosch Gen1 HMI display, Bosch Smart System (BES3) or bikes equipped with ABS.
Important: If your bike uses Bosch Smart System, please use the EBTsmart Unlock Key instead.
ABS note: The EBT Unlock Key does not support ABS-equipped bikes. If your e-bike has ABS, it cannot be unlocked with this product. For Bosch Smart System bikes with ABS, only the EBTsmart Unlock Key is relevant – and there only up to 32 km/h.
Key Features
- 2 individual licences for 2 compatible Bosch e-bikes.
- 100% browser-based – no software installation required.
- Compatible with many Bosch Gen1, Gen2, Gen3 and Gen4 systems on BES1 / BES2.
- Not compatible with Bosch Gen1 HMI display, Bosch Smart System or ABS-equipped bikes.
- Permanent unlock – remains active even after battery replacement.
- Reversible at any time – the original setting can be restored whenever required.
- No chip, no dongle, no flashing and no motor disassembly.
- Depending on the bike setup, motor assistance of up to approx. 45 km/h is possible.
- Gen2–Gen4: the display typically shows half the actual speed while riding.
- Gen1: display values remain correct.
Not all Gen4 motors are the same – the charging port tells the story
Bosch Gen4 motors exist in two different electronic system generations:
Round charging port = BES2 → compatible with the EBT Unlock Key
Square charging port = BES3 / Smart System → not compatible
If your Gen4 bike uses the square charging port, it belongs to the Bosch Smart System family. In that case, you need the EBTsmart Unlock Key.
