This advanced module removes the factory speed limiter, allowing riders to unlock the full potential of their electric bike while maintaining accurate ride data on the display. Functionality Once installed, SpeedBox 3.3 enables your e-bike to display real-time metrics such as: Maximum and average speed Daily mileage Cruising range Activation is performed directly through the bike’s control unit: Briefly press the WALK assist button while stationary. The display will show 5.0 km/h (3.1 mph), indicating that tuning is active. You may adjust the speed limit up to 99 km/h, though it is recommended not to exceed 50 km/h to reduce the risk of error codes. To deactivate, press the WALK button again while stationary. The display will show 2.5 km/h (1.6 mph), and the limiter will reset to 25 km/h. For bikes without a WALK button, use the - + - + button combination to toggle the tuning on or off. Speed Limit Customization You can fine-tune the maximum speed of electric assistance using the following methods: Switch modes three levels down, then three levels up to display the current limit. Adjust by briefly pressing the WALK button or rotating the rear wheel 360°. Speed limit indicators: 1.5 km/h = 15 km/h 2.0 km/h = 20 km/h 2.5 km/h = 25 km/h 3.0 km/h = 30 km/h 5.0 km/h = 50 km/h 9.9 km/h = 99 km/h The last displayed value will be saved after five seconds of inactivity. Post-Ride Protocol After each ride: Leave the bike powered on until 0.0 km/h is displayed. Do not remove the display until the countdown process is complete. For short stops, keep one foot on the pedal to prevent countdown initiation. For longer stops, allow at least a partial countdown. After extended rides, the countdown may take several minutes. Installation Installation is straightforward, with color-coded connectors and detailed instructions available. Disassembly is equally simple. If installing on a brand-new bike, ride at least 10 km before activating the tuning.
