So just as I'm starting to get comfortable enough with my bike to start riding it on my commute, I find myself in need of a folding bike, because part of my commute involves a regional train (BART) that doesn't allow non-folding bikes during my commute hours. I've found a few that look interesting, but I've noticed they all seem to have a weight limit of around 230 lbs, and I exceed that by about 30 lbs (and don't expect that to change anytime soon). Do any of my fellow Athenas or Clydesdales have a folding bike? What's your experience with them? How much attention should I pay to the weight limit?
