I haven't had a bike for about 10 years now and i want to get back into riding one. I don't race or tour and i would just like a bike to ride to work (15 minutes ride) and go go to the shops etc but as i travel a lot on the train i'd like to carry it with me to help me get to my destination. Based on that i'm probably looking for a more urban based bike, not for steep hills etc but comfortable and fairly swift if i put the work in. I don't have a lot to spend, maybe £200/$300 tops and i'm wondering what i could get for that sort of money. Any info/advice is appreciated
