Since wear and tear on the roads is roughly proportional to vehicle weight, perhaps a tax or purchase surcharge based on vehicle weight applied to all vehicles (trucks, cars, motorcycles, bicycles) would be appropriate? It might be several hundred dollars for a heavy truck, but only a few pennies for a bicycle. That way nobody could whine about cyclists not paying their way (despite the fact that only federal and state level roads are funded by the fuel tax, while city and township roads are funded by property tax, regardless of whether you have a motor vehicle).
