SpeedBox2 for Yamaha is a revolutionary process-control module which suppresses the speed limiter of your electric bike. After installation and activation of your SpeedBox for Yamaha the display will show actual values. Values such as maximum speed, average speed, distance travelled daily and range are correctly displayed.
The SpeedBox2 for Yamaha is activated by pressing the LIGHT button, which is located on the control panel. After pressing this button, the current speed of 5.0 km/h is displayed on the control panel for about 2 seconds. This means that the SpeedBox2 is activated.
When you press the LIGHT button again, the current speed of 2.5 km/h is displayed. This means that the SpeedBox2 is deactivated, and everything works as if the SpeedBox had never been installed. The supplementary assistance of your electric bike now works up to its original speed limit of 25 km/h.
The light button controls both the lights on your bike and the activation and deactivation of your SpeedBox tuning kit. If you don’t have lights installed on your bike, or you want to control the SpeedBox separately, there is a second method to activate and deactivate the SpeedBox:
This second method involves pressing the up down buttons: UP → DOWN → UP → DOWN within two seconds. To deactivate simply press the up down buttons again in the same order.
