Right, Movans thread on transporting her Trike got a recommendation of Pheonix trailers, so I had a mooch. Towing Dolly, braked, interesting. Now as I understand (so don't bang on on this bit) if the 'trailor' has brakes they must all work, front wheels on said braked dolly no issue so either cable as per a frames to actuate all brakes, academic on front but that gets the back working or same idea but use a brake buddy. Now I realise this would give an issue with a trike as chances are everytime you applied the brakes (dragging trike backwards) the front wheel may lock but I thinking car here. Light blue touch paper and run time, hows the legal work here?
