You will be told ebikes aren't allowed on non motorized bike trails.
I respond by asking where in the regulations does it state ebikes are banned. They point to the section on motor vehicles (noted earlier in this thread). I respond referencing the state law that low speed electric bikes are classed as bicycles, governed by the same laws as all bikes in the state. The county cannot classify ebikes as motor vehicles, that is a state and federal regulatory issue. They can't lump ebikes in with motorcycles, scooters and mopeds. If they want to ban ebikes they have to pass new regulation to do so. That is a lengthy and far more public process, where people do have some say.
I'm not denying the letter, or the spirit of the law. We see poorly written laws all the time, but we know what the law means. That would be the spirit of the law. In this case low speed electric assist bikes aren't acknowledged in any way. To suggest motor vehicle laws apply doesn't make sense. I believe the federal regulations were passed in 2009 and the state's passed in 2014. If they meant to ban ebikes in 2017, they did a really poor job of understanding just what an ebike is, and a worse job of regulating them.
There has been some public pressure. Hopefully they'll see sense, otherwise someone will get a ticket one day.
