wheel size

For a perfect function of the Pendix eDrive we need the wheel size of your bicycle, which should be equipped with Pendix. You will find the details on the sidewall of your tyre. Usually the information is in the following form: 37-622, 26 x 1.6.

The 26 corresponds to 26 inches, which you would have to specify in this example.
