Re: Motorized vs. Electric
In my opinion an eBike with less than 750w would be legal to ride on any trail built with federal money, unless a local municipality or state has passed an ordinance against it. However passing such a law after the fact may require the state or municipality to refund some money back to the fed.
These federal laws about eBikes cover other kinds of electric vehicles too. Like Rascals, and Segway's. Here in downtown Dallas there's a place that sells guided tours using Segway's. The tour guide started taking the groups on the Katy trail. The city of Dallas told them they would have to stop riding the the trail because it's just for joggers, and bicycles. The tour operator went to city hall and informed the city that federal law allows vehicles such as Segways to operate on trails funded with federal dollars. The city backed down.
