there are no weight allowances Mo...if brakes are fitted they must work regardless of weight.I think you are right John.....
But weights come into it,,,, Not sure what they are though...
Friends of ours tow their trikes on a similar frame with the front wheel off the ground with no rear brakes..
It was explained but I have forgot, what the weight`s were.... as towing like that leaves a very expensive bit of gear open to the elements and stones thrown up by the towing vehicle.. :sad:
see paragraph 2......first three lines.
