I agree with the reviewers trying to warn you off this bike. I bought it because I wanted a cheap bike for infrequent use but foldable, didn't mind too much that it was really heavy and slow. I took it to a reputable local bike repair shop because gears were slipping and the guy looked at it and me as if I had brought something smelly in. He charged me a fiver and told me there wasn't much else he could do, the gear-control incompatible with the gear cables, etc. etc. I was going to take it to the tip but instead left it unlocked where it was duly stolen by some unfortunate, and spent more on a better fold-up bike. Avoid!
