How can I restart my COBI.Bike or my eBike if the internal COBI.Bike battery is deeply discharged?

If the internal battery of the COBI.Bike is deeply discharged and your eBike is equipped with a frame or rack battery, try switching on the eBike at the on/off switch of the battery. The COBI.Bike is now automatically supplied with power from the eBike battery and as a result the built-in battery is recharged If the internal battery of COBI.Bike is deeply discharged and your eBike is equipped with a PowerTube battery with the on/off switch covered, try connecting the eBike to the Bosch charger. This activates the eBike system and the COBI.Bike is now automatically supplied with power from the eBike battery and as a result the built-in battery is recharged
