Description
NOTE: Conventional tuning modules offer only limited functionality compared to today’s e-bike standards. They often rely on complex and unintuitive display button sequences for activating, deactivating, or adjusting speed limits. This makes operation cumbersome, especially during a ride. In some cases, users must stop the bicycle and manually rotate the rear wheel multiple times to initiate or confirm the selected setting — a process that is inefficient and inconvenient for real-world riding conditions.

In contrast, the EPAspeed B.Tuning series represents the next generation of e-bike tuning — fully app-controlled, firmware-resistant, and designed for effortless operation. With Bluetooth connectivity, intuitive controls, and invisible tuning functionality, EPAspeed delivers precision, reliability, and freedom unmatched by conventional solutions.

• Tuning Control – Instantly activate or deactivate tuning
• Adjustable Speed Limits – Set your preferred maximum assistance speed
• Invisible Tuning Mode – Undetectable operation for smooth and safe performance
• Trip Recording – Automatically save and review detailed ride statistics

Not compatible with: RideControl Go, Speedbox App
Reliable third generation tuning chip for e-bikes with Giant 2017-2022 motors (except SyncDrive Pro motor with RideControl Go)
SpeedBox tuning chip enables to suppress the speed limiter on your electric bike. After the chip is installed your e-bike’s display shows real data, such as maximum and average speed, daily mileage and cruising range.
HOW DOES SPEEDBOX 3.0 WORK?
The tuning kit can be activated directly on your bike’s controller. After pressing the WALK button, a value of 9.9 km/h (6.2 mph) is displayed and from now on you will be able to ride at a speed of 40 km/h, 50 km/h and even more than 60 km/h.
To deactivate the tuning kit, press the WALK button again. The value of 2.5 km/h (1.6 mph) will appear on your display and the speed limit will reset to 25 km/h. Your e-bike will then work the same as before installation of the chip.
SpeedBox was also designed for e-bikes that do not have a classic control unit with Walk button. In this case you can just use the combination of + – + – buttons and SpeedBox will be activated. You can easily deactivate SpeedBox in the same way.
You can set the maximum speed of an electric assistance by changing modes by switching modes three levels up and then three levels down. An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by pressing WALK button shortly or by turning the rear wheel 360°. The value of 1,5 km/h on the display corresponds with the limit of 15 km/h, 2 km/h corresponds with the limit of 20 km/h, 2,5 corresponds with 25 km/h, 3,0 corresponds with 30 km/h, 9,9 corresponds with 99 km/h etc. The last displayed limit will be saved after 5 seconds of inactivity.
ASSEMBLY
When connecting the SpeedBox chip to an e-bike you will find connectors coloured to make installation very simple. We have prepared detailed instructions and videos to make installation easy for you. Disassembly of our tuning chip is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us.
If you are planning to install SpeedBox on a brand-new bike, make sure you ride it for at least 1 km before the chip is activated.
