Main Product Information

Tuning kit for e-bikes with Bafang M200 M410, M500, M510 motors.

SpeedBox 3.2 enables you to double the speed limit of an e-bike from the original 16 mph (25 km/h) to 31 mph (50 km/h). After the tuning is installed, your e-bike’s display will show real data, such as maximum and average speeds, daily mileage and cruising range.

Note: The Speedbox App is an application specially designed for Speedbox B. Tuning products only. With a non-Bluetooth Speedbox product like this one, the Speedbox App is unavailable.

SpeedBox 3.2 B.Tuning for Bafang M200 M410 M500 M510

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

The tuning kit can be activated directly on your bike’s display. After pressing the LIGHT button or +-+-, a value of 99 km/h (62 mph) is displayed and from now on you will be able to ride at an unlimited speed.

To deactivate the tuning kit, press the LIGHT button or +-+- again. The value of 25 km/h (16 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.

You can set the maximum speed of an electric assistance by changing modes by switching modes three levels down and then three levels up. An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by pressing LIGHT button shortly or by turning the rear wheel 360°. The last displayed limit will be saved after 5 seconds of inactivity.

This tuning kit is compatible with motors:
- Bafang Max Drive M200 M410, M500, M510


Not compatible with:
- Bafang Max Drive M300
- Bafang Max Drive M400
- Bafang Max Drive M420
- Displays with UART connectors

In case of updating the software of your e-bike, uninstall SpeedBox from the e-bike first, update the software and reinstall SpeedBox.

We use original connectors for the production of SpeedBox chips ensuring that the installation process is very simple and the chip is connected properly. We have also prepared detailed instructions and videos to make installation easy for you. Disassembly of the 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 0.6 miles (1 km) before the chip is activated.

Took my time to carefully install the kit by following pdf instructions, but actually it was dead simple to fit (even lowering motor) Used blobs of hot glue to fix electromagnet securely to motor (as shown in Aussie YouTube vid). Job done! First test-ride gave me a biiig grin. The bike now rides more like a regular bike as you don’t hit the ridiculous ‘treacle wall’ after passing 15.5mph. Fastest I’ve got so far is 24.5mph on the flat in eMTB mode. My happy place is around 17/18mph in eco mode. Purion display stats are out the window, so use Strava app or similar to clock speed, distance etc. I’m weary to not exceed 25mph (as advised) and occasionally check sensor/magnet distance stays within required space/mm limit to avoid error messages. Switch off flow app software updates to avoid error messages & consider the app redundant before you start. It’s worth it! Jim, Scarborough.
