EBT Unlock Key – 2 Licenses for Bosch Gen1–Gen4 (except HMI and Smart System)
Unlock two e-bikes – full power, browser-based, no installation required
This bundle includes two separate EBT Unlock Keys, allowing you to unlock the 25 km/h speed limit on two Bosch e-bikes (Gen1–Gen4, excluding Gen1 with HMI display and Smart System). Each license is unique and can be used independently.
No chips, no apps, and no dongles – just your PC or MAC, a USB cable, and our secure browser platform (URL after purchase).

Key Features
- 2 unlock keys – ideal for households, friends, or workshops
- 100% browser-based – no app, no software installation
- Fully reversible – re-lock anytime
- Compatible with Bosch Gen1 (Intuvia display), Gen2, Gen3, Gen4
- Not compatible with Bosch Gen1 (except HMI) and Bosch Smart System
- No hardware mods required – plug & play over USB
- The EBT tool may cause Bosch Gen2–Gen4 displays to show halved speed readings. This is not a malfunction, but rather a technical characteristic. Bosch Gen1 units display true speeds. No 504 errors occur.

Important: Tuning e-bikes means that they can no longer be used on public roads. Legal use is therefore only possible on private property or, where permitted, in competitions. Riding an e-bike modified by tuning on public roads can lead to criminal charges for riding without a licence and riding without insurance. Tuning your e-bike may result in the loss of warranty rights and manufacturer's guarantees. In addition, in the event of an accident, tuning may result in the loss of insurance coverage and victim assistance benefits. The e-bike modified by tuning is exposed to an additional load due to the higher speed, which can lead to safety risks.
