I am thinking of getting a fold up bike and have been told that the Brompton’s are simply the best. Are there any Brompton owners out there? I would be interested in your feedback. Does anybody take it on the bus\luas\train with them? Are you allowed? Is it out of the question to leave it on the street locked, irrespective of how good the lock is? Does anybody have any misgivings with the Brompton? They sure are expensive – is it worth the price? I would see it as a long term investment.
