No, they're regarded as motor vehicles because they're propelled by an 
internal combustion engine - so can only be used on the road if they 
conform to the regulations controlling internal-combustion engine-
propelled devices. There's similar regs - but less onerous - controlling 
electrically propelled devices.

Doesn't mean that things that aren't internal-combustion or electrically 
propelled aren't vehicles.
