We have those kind of taxes as well. But it's monthly.
If you don't pay them the system automatically knows and sends you a fine. Same goes for insurance (insurance is obligated).
In both cases the insurer also doesn't have to cover anything you do.
You can "schorsen" (take a vehicle formally out of service) for some time so you don't need to pay or insure, but it can't be on the street then.
It's 11 euro a month per bike (E bikes and cars were free until last year). Gas cars vary from 30-120 a month. Diesels 60-250 a month.
Makes your taxes look cheap!
