The good people over at Cycle Lifestyle Magazine have launched a campaign to create a single cycle map for London. I think it is a damn good idea, as I spend a lot of time using a combination of the TFL cycle journey planner (sometimes brilliant, sometimes bizarre), my battered old A-Z and a lot of instinct. Really, it was only experience and the collective wisdom of an online bike forum that led me to a reasonably direct route from Oxford Streed to Waterloo Bridge that missed out the frankly lethal Regent's Street. A straightforward, colourful bike version of the tube map would be invaluable.
You can sign a petition here and have a look at the prototype map here. I hear that an easier to read, more stylised version is in production so do show your support for the concept, not the finished product
