A few weeks ago I wrote about my commute and how I thought I needed a new bike to bike up and down hills to work. People suggested thin tyres, more gears and panniers. Well I have realised I have some money to buy a new bike. So does anyone have any suggestions for a good commuting bike? What I should look for etc? Any essential accessories? Last time I went for style...I'm being practical this time. I want to be able to bike to super market and library with it too....both a 10 min bike ride away.
