Electric bicycles aren't allowed to exceed 25km/h anyway, so legally only human-powered bikes can exceed the 30km/h speed limit. If the owners messed with their bikes to override the speed limiter, I doubt they'll care about the 30km/h signs.
Mopeds and similar vehicles (the ones with license plates and mandatory helmets) will probably be hit the worst.
