Bosch Smart System Tuning License Code (BES3)
Software Unlock – No Chip & No Hardware Installation Required
Enjoy more riding freedom on your modern Bosch Smart System e-bike – fully digital, no tuning module installation, and no motor disassembly required.
Modern Bosch e-bikes offer impressive motor performance. However, from the factory, motor assistance stops at 25 km/h (15.5 mph). On longer rides or slight downhills, this can feel unnatural – you keep pedaling, but the motor cuts off.
With the Bosch Smart System Tuning License Code, this electronic speed limitation is removed via software.
Activation is done conveniently from home – and can be reversed at any time.
Important Update (Please Read Carefully)
Currently, the maximum assisted speed is approximately 32 km/h (20 mph).
The display shows the real speed correctly (no halved values like with many tuning modules).
The manufacturer is planning a future update expanding support to approximately 40–50 km/h (25–31 mph).
Very important:
If you already own a license code, you do NOT need to purchase a new one.
After the update, simply:
Deactivate tuning
Reinstall tuning
→ and you will automatically receive the new features.
Activate & Deactivate Anytime (Even On The Go)
One major advantage of this solution:
You can turn tuning on and off yourself.
To Activate:
Connect smartphone via USB-C data cable
Start the program
Unlock the bike
Ride and enjoy
To Deactivate (for public road use):
Reconnect smartphone via USB-C
Disable tuning
Bike returns to original factory condition
This allows you to ride unrestricted on private property and switch back to legal configuration for public roads.
No More Tuning Chip Required
Older Bosch motors required a physical module inside the motor:
Open motor cover
Connect internal cables
Risk of water damage
Possible warranty concerns
With the Bosch Smart System (BES3), this is no longer necessary.
The adjustment is done exclusively via personal license code.
✔ No mechanical work
✔ No motor removal
✔ No additional hardware
✔ Bike remains mechanically untouched
How Activation Works
After purchase, you receive your personal activation code.
Step-by-Step:
Turn on the e-bike
Keep the display connected
Connect smartphone or PC via USB-C data cable
Open activation program
Enter license code
Speed limitation is adjusted
Typical duration: just a few minutes.
Result After Activation
The motor continues assisting above the factory 25 km/h limit.
