For the initial setup of the VELLO Bike+ and for choosing the driving modes, a connection between smartphone/tablet and the VELLO Bike+ via bluetooth is required. The system will save the chosen settings and can then be operated without Bluetooth-connection. To start the system, the cyclist then has to accelerate to about 10km/h and pedal backwards 3 times. When not ridden, the VELLO Bike+ will stay activated for 5 minutes and will then shut down automatically. The connection between smartphone/tablet and the VELLO Bike+ is therefore only needed for the initial setup and changing the driving modes, activating the electrical engine and tracking the route.
