Tuning of E-bikes with a Giant Yamaha SyncDrive
Do you have an electric bike with a Giant Yamaha SyncDrive? Does the motor automatically switch off at 25 km/h? SpeedBox will help you with that. This gadget suppresses the speed limiter. Themaximum speed of your electric bike will only be limited by your pedalling rate.
SpeedBox2 are the newest versions of our tuning kits. The speed limiter is suppressed and all the values on the display are presented in actual values.
Installing the SpeedBox will not damage any part of the motor or ebike, we only use original connectors for our products!
It is very easy to install the SpeedBox.
