Speedbox E6000 speed increasing device

Unleash the full potential of your e-bike with the SpeedBox 1.0 for Shimano E6000 motors. This tuning chip completely removes the speed limiter, allowing you to ride up to 99 km/h. The device is always active but can be easily toggled off using your LIGHT button. While your display shows true speed up to 22 km/h, you can enjoy unrestricted performance beyond that. Simple to install with color-coded connectors.
