Activate and deactivate anytime, even on the go.

One major advantage of this solution is that you can turn the tuning on and off yourself at any time.

To activate, connect your smartphone using a USB-C data cable, start the program, unlock the bike and ride.

To deactivate for public road use, reconnect your smartphone via USB-C, disable tuning and the bike returns to its original factory condition.

This allows you to ride unrestricted on private property and switch back to legal configuration for public roads whenever necessary.

No tuning chip is required.

Older Bosch motors required installing a physical module inside the motor housing. This involved opening the motor cover, connecting internal cables, and carried potential risks such as water damage or warranty concerns.

With the Bosch Smart System BES3, this is no longer necessary. The adjustment is done exclusively via your personal license code. No mechanical work is required, no motor removal is necessary, no additional hardware is installed and the bike remains mechanically untouched.

How activation works.

After purchase, you receive your personal activation code. Turn on the e-bike and keep the display connected. Connect your smartphone or PC using a USB-C data cable. Open the activation program and enter your license code. The speed limitation will then be adjusted. The process usually takes only a few minutes.

Result after activation.

The motor continues assisting above the factory 25 km/h limit. The motor does not become more powerful. It simply no longer stops assisting artificially at the predefined limit.

Benefits include more relaxed riding, higher cruising speed, a more natural pedaling feel, less effort on longer rides and improved comfort for commuting.

Compatibility.

Compatible with Bosch Smart System BES3 e-bikes from approximately model year 2022 onwards. Supported displays include Kiox 300, Kiox 500, Kiox 400C, Intuvia 100, Purion 200 and Purion 400. LED Remote with Flow App smartphone setups are also supported. Smart System hub motor variants are supported as well.

Not compatible with Bosch Generation 1 to 4 systems or S-Pedelec 45 km/h models.

Advantages over classic tuning modules.

This is a software solution with no installation required and no need to open the motor. It can be disabled at any time, no hardware is visible and it remains update capable.

Traditional tuning chips require installation, must be removed before resale, carry installation risks and often display incorrect speed values.

Technical requirements.

You need a smartphone or PC or laptop, a USB-C data cable that supports data transfer and a powered-on e-bike.

Legal notice.

After activation, the e-bike no longer complies with standard Pedelec classification. Use on public roads is not permitted. Intended for use on private property or legally approved areas only.

Important notes.

Digital license codes are non-refundable. Each code is valid for exactly one e-bike. Tuning can be disabled anytime. The display must remain connected during activation. The system is update capable for future features.

Common issues and solutions.

If the bike is not recognized, the issue is usually an incorrect USB cable that only supports charging. If activation does not work, ensure the e-bike is powered on and the display is active. If no noticeable speed increase is felt, reinstall the tuning.

Conclusion.

Bosch Smart System tuning via license code is currently the most convenient way to adjust the factory speed limitation of modern Bosch e-bikes. No hardware is required, no installation work is needed, the solution is fully reversible and ready for future updates including planned support for speeds up to approximately 40 to 50 km/h.
