My mooring neighbour is in his 70s and has one, intended to help him get between locks. Of course, CRT have now banned these from the towpath so that's put an end to his idea whilst any scrote without a boat will continue unaffected by something CRT can't possibly enforce on anyone but boaters. Fast E- bikes, e-scooters, electric trail bikes, electric unicycles, you name it - we have to put up with anyone who chooses to ride them illegally on towpaths but are the only ones who could be identified if we had one ourselves.
