I am a female cyclist living near Bristol in the UK, and I am looking to buy a new bike. I cycle to work everyday and also do a lot of cycling at the weekend. I mostly cycle on fairly well maintained roads, but I do use slightly rougher country lanes occasionally. I am looking for a bike that is light enough to make getting around a breeze, but that is also capable of dealing with the odd bump on a less smooth road. I am 5,3” and around 55kg, if that makes a difference to what bike you may suggest! I already own panniers, so the bike needs to be able to be fitted with them (it is a fairly standard rack that fits on the back). I really don’t want to spend anything over £700, and would actually much prefer the bike to cost less than £600. Any advice would be much appreciated.
