I havent riden his T-Rex... well I have, no hops or anything though. He only had it for like a day and he's had to send the wheels back. The back was starting to buckle the first day he got it! It feels a pretty good size. I'll have to see when he gets it back. The Woodstock frame sells for £150 more than the T-rex frame, I would have thought it would have made it a better quality frame. But I suppose as I'm starting off, I'd be more likely to put stress on it in the wrong places. Is there any other good bikes that are roughly the same price?
