The MV page isn't clear enough, and the rules tend to evolve. Somewhere there must be a description of what motorized vehicles do not need registration as an MV.
For ex, motorized wheelchairs do (or might) need a license, but electric tricycles do (or might) not.
I didn't apply to bring my MV because I won't have time to finish it. But I've an alternate project in mind that would be scratch-built and electric and have three wheels. For technical reasons I can't add bicycle chains and call it a bike (not honestly functional ones).
How do I determine the line between a three-wheeled motorized vehicle that does need registration (say an old mutated industrial cart) and one that does not (say an electric tricycle)?
Thanks ...
