Your e-bike display will show a value of 3.5 km\/h (2.2 mph) and from now on you will be able to ride up to 35 km\/h.

An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by activating WALK assist function shortly or by turning the rear wheel 360°. The value of 2.5 km\/h on the display corresponds with the limit of 25 km\/h, 3.0 corresponds with 30 km\/h, 3.5 corresponds with 35 km\/h etc. The last displayed limit will be saved after 15 seconds of inactivity.\u003c\/p\u003e\n\u003cp\u003eAfter finishing the ride, leave the bike on until a value of 0.0 km\/h is displayed. During this process the remaining time will be displayed. Then it is safe to turn off your bike and you can start looking forward to your next trip.
