Maybe you didn't think this one through. There are some factors to consider:

* Many, if not most, cyclists are also motorists who already pay gas taxes, sales taxes on their cars and bikes, sales taxes on bike products and sales tax on bike repairs.
* Many cyclists are children whose parents are taxpayers; is the tax assessed on the kid or doubled up on the parent?
* Would the same tax be applied to any wheeled conveyance that uses pavement, such as roller skates, skate boards, scooters and “hover” boards?
* What exactly is a bicycle’s portion of road un-maintenance, as compared to that of a motor vehicle?
* Are you actually suggesting that if there isn’t a tax on cycling that “sharing the road” goes out the window and it’s open season for motor vehicles to run over cyclists?
