Call a Bike

1) Registration
To rent a CallBike, you first need to register. When registering, you decide whether you would like to pay by credit card or have the amount due deducted from your bank account. If you provide your mobile phone number during registration, the rental system will automatically recognize you and you will not need to enter your customer number when renting later. You can choose between registration by phone or online registration:
Customer hotline: 0700 0 5 22 55 22

2) Renting
CallBikes are equipped with electronic number locks. If the lamp on the lock flashes red, the bike is still occupied. If it flashes green, the bike can be rented. If so, call the framed telephone number on the lock and listen for the code required to open the numbered lock. If you are not calling from your registered mobile phone, you will need your customer number. Enter the code into the data entry display, and off you go.

3) Making a Stop
If you want to take a short break, simply lock your bike and press the lock button on the side. You will be able to unlock it later using the same code.

4) Returns
Return your CallBike by connecting it to a fixed object and pressing the lock button. The display will prompt “Rückgabe Ja/Nein” (“Return Yes/No”). Choose ”Ja” (“Yes”). Your confirmation code appears. You will need the code when calling the number in the box to report the bike’s location and the confirmation code. This is important because only then will your rental period be over!
