There is quite a difference in price (Schwinn is £189.99 and the Boulder is the £229.99). I was hoping you could tell me which overall is the best bike and whether the disc breaks on the Boulder will be superior. I am new and looking for a decent new bike (my parents will not let me get a second hand one), would these be good for road use and some fairly basic trails. Thanks a lot and would these bikes be "upgradeable"? Thanks again and are there any other bikes at this price that would be good considering the components?
