• Supports the latest software versions (LED-Remote 11.9.3 / Firmware 11.13.0, 12.13.0, and 13.13.1)

Easy installation and use

• No PC or app required – all settings are made using the e-bike's control buttons

New features

• Customizable top speed – you can set the maximum speed supported by the motor using the + and - buttons (with 1 km/h precision)

• "Chip Reset" function – restore factory settings or transfer the tuning to another e-bike
• Normal or "STILL ON" mode – choose whether you want the tuning to be automatically on whenever the bike starts
• Correct speed remains visible – the display shows the speed correctly up to 22.9 km/h, and for higher speeds, the reading appears using the last digit and decimal (e.g., 23.3 km/h = 33 km/h, 24.0 km/h = 40 km/h)
