Can several phones be connected to the wheel?
As soon as an iOs or Android phone is equipped with the Teebike application, it can be connected to a Teebike wheel, there's no unique connection.
CAREFUL : Meaning that you can change which phone is connected to the wheel, but you cannot have more than one phone connected at a time. Since the Bluetooth signal only accepts one connection, the phone connected first will be the one controlling the wheel.
If you need to connect another phone to the wheel, you will have to disconnect the first phone and then connect the second one.
