With the SpeedBox, you’re no longer limited to 25 km/h. You’ll experience the full power of your e-bike, determined solely by your pedaling cadence. This is our most powerful and versatile product, displaying the actual speed and allowing you to set a custom maximum speed. The chip is meticulously optimized for performance and maximum riding enjoyment. This e-bike kit removes the speed limit of the pedelec, enabling you to ride at unrestricted speeds.

  • Activation of the chip with the press of a button: LIGHT button / + - + - Maximum speed: unlimited Speed limiter: yes Display: real values
  • Compatible with motors: Bafang Max Drive M300 Bafang Max Drive M400 Bafang Max Drive M420
  • Not compatible with: Bafang Max Drive M500 SpeedBox App Displays with UART connectors
  • You can activate the SpeedBox 3.1 on an e-bike display. After pressing the LIGHT button or + - + -, the display briefly shows 99 km/h. From that moment, you can ride at unlimited speeds. Press the LIGHT button again to deactivate the product function. The display will show 25 km/h, and the speed limit of 25 km/h will be reactivated. The pedelec will then function as it did before installing the tuning.
  • Anyone can install a chip in an e-bike with simple tools! We have provided detailed instructions so you can install it comfortably at home. Removing the tuning chip is as simple as installation. If you encounter any issues with installation, please don’t hesitate to contact us.
  • If you want to install a SpeedBox on a brand new bike, you must ride at least 10 km on this bike before activating the chip for the first time. https://youtu.be/n9GaBxTUd_I?si=cowdTR0kL5S5Hh8G
