Flecc your right, as always! The chain, although looks like a complicated system that is bound to give problems, is trouble free. I regularly have one of these in and out of the car boot with no issuesThe way it goes it hardly needs the chain though, very moped like performance.
Seriously, the chain arrangement is very much like that on recumbents, and no-one I've seen reports from about riding the A2B Metro has reported trouble with it.
Hi Overlander,Well guess thats why ) Have you any more info on the new models offroad mod?
