SpeedBox 1.1 B.Tuning Kit for DJI Avinox (M2, M2S)
Derestrict your e-bike to reach maximum speed!
The active tuning kit makes the speedometer show a slower speed, but the SpeedBox Connect app displays all riding data accurately.
Tuning kit unlocks unlimited speed. You can also set your own preferred speed limit via the SpeedBox Connect app.
Once fitted, this tuning kit needs to be activated and can be deactivated at will — via the SpeedBox Connect app or the + − + − button sequence.

What does this Tuning Kit do?
With the B.Tuning version you can see your real riding values in the SpeedBox Connect app – right on the display of your phone.
Achievable speed
Calculate your speed
The achievable speed mostly depends on the eBike model. Enter your own values:
Check the highlighted values to see your speed.
Theoretical value from cadence and gearing only. Your real speed also depends on the motor, the tuning kit, the rider and the terrain.
Speed = cadence [rpm] × wheel circumference [mm] × front chainring teeth ÷ rear sprocket teeth × 60 [min/h] ÷ 1,000,000 [mm/km]
Which Speedbox Tuning Kit do I need?
This is the tuning chip for e-bikes running the DJI Avinox M2 or M2S motor.
Compatible with:
- DJI Avinox M2 motors
- DJI Avinox M2S motors
- All Avinox displays
- SpeedBox Connect app
If your e-bike uses the earlier DJI Avinox M1 motor, you need SpeedBox 1.0 B.Tuning for Avinox instead.
Firmware updates: DJI regularly releases new firmware for Avinox motors, which can affect compatibility or increase the risk of tuning detection. We strongly recommend not installing those updates. One advantage of the B.Tuning version is that the chip itself can be updated over the app — no need to buy a new one — provided your chip carries the Factory Bootloader marking on the back.
How to install this Tuning kit?
If you are fitting SpeedBox to a brand-new bike, ride at least 10 km before activating the chip.

FAQ & legal
How does SpeedBox 1.1 B.Tuning work?
Activate/deactivate the tuning before the ride (when the e-bike is standing still), not during riding!
There are two ways to switch tuning on and off:
- Through the SpeedBox Connect app over Bluetooth
- Using the handlebar buttons in the sequence + − + −
You can also set your own custom speed limit in the app rather than running fully unlimited, plus monitor live ride data and save ride records.
Hide Tuning function: once enabled, tuning can no longer be switched on using the buttons on the e-bike — only via the app.
Important legal note!
Installation may void the warranty on your e-bike.
For your safety, use appropriate protective gear and ride with maximum caution at higher speeds.
SpeedBox products are thoroughly tested and carry a Lifetime Warranty from the manufacturer.

eBike Software Updates
Warranty does not cover damage resulting from eBike software updates. Remove the tuning kit before updating the software. Check with us first to ensure the kit is compatible with your updated eBike. We cannot guarantee that the kit will function the same after updates. Please exercise caution. If your Speedbox tuning kit needs updating due to updated eBike software, please contact us at hi@twowheelsempire.com. Preliminary costs are 49£ + shipping costs.
What is the SpeedBox App?
SpeedBox App specifically designed for SpeedBox B.Tuning uses Bluetooth technology to connect your e-bike to your mobile phone. After downloading the application and connecting your phone to your electric bike, you can track the current data and riding parameters on your phone. You can save your trips, compare them with friends and monitor your own performance, so just enjoy the ride to the fullest and leave checking the parameters for later!
Main Features
SpeedBox B.Tuning chip can be used even without the SpeedBox App. However, it is a great accessory that will give you a complete overview of your performance. Most sport apps use only rough estimates of values. That’s why these data may differ from the real electric bike data by up to 20%. SpeedBox App displays completely accurate data, which is read directly from the electric bike's control unit.
