EBT Unlock Key – Full FAQ
1. General Information
What is the EBT Unlock Key? The EBT Unlock Key is a browser-based software tool that unlocks Bosch motors (Gen1 to Gen4) by removing the 25 km/h speed limit.
How is it delivered? Exclusively via email. You receive a digital license code with instructions.
What makes EBT unique? 100% digital. No chip, no hardware, no app install – works directly in your browser.
Is the tool visible on the bike? No. The change is internal. There’s no trace of tuning visible externally.
Here you’ll find everything you need to know about Bosch e-bike motor generations, compatibility with the EBT Unlock Key, and how software tuning compares to hardware-based solutions. Jump directly to the section you're most interested in:
To help you better understand which Bosch e-bike motors are compatible with the EBT Unlock Key, we’ve included an overview of the differences between Gen1, Gen2, Gen3, and Gen4 systems. Learn which version you have – and whether browser-based tuning is possible.
Bosch’s first generation, often referred to as the Classic+ Line, includes systems with either HMI or Intuvia displays. The EBT Unlock Key only supports the Intuvia variant (BES1), which shows full and correct speed values. HMI displays are not supported. These early systems are typically found on older city or trekking bikes. Unlock Bosch Gen1 Classic+ Motor
Bosch Gen2 Tuning – Active & Performance Line (2014–2017)
Gen2 motors brought a significant step forward in Bosch’s evolution. These systems use BES1 connectors and are compatible with the EBT Unlock Key. However, due to system design, speed values are shown at half the actual speed when unlocked. This affects displays such as Purion, Intuvia, and Nyon. Unlock Bosch Gen2 Performance Line Motor
Bosch Gen3 Tuning – Active Line Plus & Performance (from 2018)
Gen3 systems marked Bosch’s transition to the BES2 connector (round plug). The EBT Unlock Key works well with these systems, but like Gen2, speed values appear halved on the display. Most commonly used on city and hybrid bikes, these systems offer a good balance between performance and weight. Unlock Bosch Gen3 Active Line Plus Motor
Bosch Gen4 Tuning – Performance Line CX (up to 2022)
Gen4 Performance Line CX motors are widely used in eMTBs and trekking bikes. The key distinction is between BES2 and BES3 versions. If your Gen4 motor uses the round charging port, it’s BES2 – and fully compatible with the EBT Unlock Key. If it has a square charging port and uses the Smart System (e.g., Kiox 300, LED Remote), it’s BES3 – and not compatible. Unlock Bosch Gen4 Performance Line CX Motor
Still unsure? Use our comparison table below or check the shape of your charging port. You can also email our support team with a photo – we’ll help you identify your system.
The following table provides a compact overview of all Bosch motor generations from Gen1 to Gen4 – including connector type (BES1, BES2), display compatibility, and browser-based tuning support via the EBT Unlock Key. Unsupported systems (e.g., Gen1 HMI, Smart System BES3) are clearly marked.
Compatibility Tip: Not all Gen4 motors are the same. There are two versions:
Gen4 with BES2 (round charging port): Compatible with the EBT Unlock Key
Gen4 with BES3 (square charging port / Smart System): Not compatible
In the UK and other markets, the BES3 version is often referred to as “Bosch Smart System” or “Performance Line CX with LED Remote.” If your Bosch Gen4 motor has a square charging port and uses a Kiox 300 or LED Remote, it is likely a BES3 system.
If you're unsure whether your bike uses BES2 or BES3, just compare your charging plug:
The EBT Unlock Key is compatible with the round plug version (BES2):
4) Comparison of software tuning and hardware tuning
There are many perspectives when it comes to tuning – and no one-size-fits-all solution. This comparison aims to help you find your own position by highlighting the differences between software-based and hardware-based tuning approaches.
While hardware solutions like tuning chips and dongles have been around for years, software tuning represents a modern, flexible, and minimally invasive alternative. It can be a valuable upgrade for technically savvy riders looking for control, reversibility, and convenience.

Important Notice
Unlocking your Bosch motor will reclassify your e-bike. Public road use without registration and insurance may be illegal in many countries. Always check your local regulations. MountainTuning is not liable for misuse.
Important Notice Regarding E-Bike and E-MTB Tuning
Please be aware that modifying your e-bike or e-mountain bike through tuning – whether by software or hardware – may have significant legal, technical, and safety implications depending on your country or region.
Legal Considerations
Loss of street-legal status:
In many countries, tuning removes the vehicle’s classification as a standard e-bike or pedelec. As a result, it may no longer be legally used on public roads or cycle paths.
Restricted use:
Tuned e-bikes are typically only allowed on private property or designated off-road tracks and competitions, depending on local regulations.
Possible legal consequences:
Operating a tuned e-bike in public may lead to legal issues, such as:
Requirements for vehicle registration, insurance, and a driver’s license
Violations of traffic and insurance laws
In some countries, using an unregistered or uninsured tuned vehicle may result in fines or penalties
No liability or insurance coverage:
In the event of an accident, insurance providers may deny coverage, and victim compensation programs may not apply. This could lead to personal liability for damages or injuries.
Warranty voiding:
Any tuning may void manufacturer warranties and affect consumer rights.
Technical and Safety Risks
Increased mechanical stress:
By removing speed limitations or altering motor behavior, your e-bike is exposed to greater loads on brakes, drivetrain, and electronics.
Accelerated wear and reduced safety:
Components may wear out faster, and performance could be compromised, especially at higher speeds for which the bike was not originally designed.
Use at Your Own Risk
MountainTuning products are intended for private use only.
We do not recommend using tuned e-bikes on public roads.
By using any tuning product, you agree to take full responsibility for any legal or technical consequences.
Always check the laws and regulations in your country before making any modifications to your e-bike.
