Thanks Wiggie! Fortunately OR unfortunately we get to go state by state Which makes more problems than its worth...And we have less options.In Britain,we have Single Vehicle Approval which allows the registration of own build bikes in Low Power Moped, Moped or Motorcycle categories. For a small amount of bureaucracy there is a procedure that entitles a motorcycle that is tested for safety and conformity to basic rules to be used on the road.
Only Low Power requires the fitting of usable pedals, with the proviso that the device can only reach 16mph unassisted.
