Review on Xspec 20" Folding City Commuter Bike - Lightweight & Efficient 7-Speed Design For Urban Travel by Shawn Mortensen

.and by good terrain I mean roads or concrete paths. Don't try to jump a curve or ride on gravel. That said.it's perfect for my use. I ride back and forth to work, that's it, and it's perfect for that. It folds up well and easily, and it's light enough to carry upstairs.Only issues are the front column wobbles a bit and the 20" wheels can be unstable at startoff, but that's likely a training issue (I was used to much larger bikes)So.pull the trigger if you just need an inexpensive commuter bike and don't do any distance riding.
