You can check our installation video on YT https://youtu.be/Nyhp6NwMN3k?si=cEdVNq2N-O7aBqXF You can adjust the speed limit in the App or manually by cycling through modes (TURBO → TRAIL → ECO → OFF → ECO → TRAIL → TURBO). The default limit is 25 km/h. Each press of the WALK button raises the limit by 5 km/h. For example, 2.5 km/h on the display = 25 km/h limit, 5.0 km/h = 50 km/h. The set limit is saved after 5 seconds of inactivity and must be confirmed by turning the bike off and on twice. You can check the current limit via the App or the + - + - button combo.
