We recommend using additional safety features and protective products to avoid injury. For short breaks, it is advisable to keep one foot on the pedal so as not to start the "countdown" trigger process so you can continue seamlessly.
To connect the SpeedBox chip to an e-bike, we use colour plugs that are equipped with a key for correct connection, so installing the chip is really easy. We have written detailed instructions and created videos that allow every customer to install the SpeedBox. Removing the tuning chip is as easy as installation. If you have some connection problems, please do not hesitate to contact us.
Please note that the warranty for the SpeedBox products does not apply to malfunctions caused by updating the engine. For longer stops, allow at least a partial "countdown" (kilometre deduction). Do not remove the display from the electric bike until the "countdown" (kilometre subduction) is complete. We recommend not to update the software of the e-bike.
If you want to install a SpeedBox into a brand new bike, you need to ride at least 10 km on this bike before starting the chip for the first time. https://youtu.be/wbRFMx4gZgs?si=sK6LJhoY40URLVKg
E-bikes equipped with SpeedBox must not be used on public roads, bike paths or public places.
