The brands in short
- SpeedBox – Czech maker building tuning kits since 2014. B.Tuning versions have Bluetooth and an app: real speed, trip data, on/off.
- PearTune – compact electronic kits for the most popular motors, including Shimano with Di2.
- VOLspeed – popular for Yamaha and Giant motors.
- BadassBox – a simple plug-and-play solution.

How to choose
- Identify your motor and display (in the bike specification or on the motor).
- Decide whether you want an app and real speed – if so, choose B.Tuning or another app-controlled kit.
- If your system detects electronic changes or you prefer not to touch the electronics, choose the mechanical SPEEDi.
- Check the compatibility list – some models (such as certain Yamaha city bikes) are not supported.
