Yes, that's true about the free cycling maps at the tube stations! I had forgotten about them. There's one for each area of London, about 18 in total. You can also ask for them on the web I think (Transport for London or sth). You can also get a free one from Southwark in their website. But they are not as nice as the one I was talking about, which I think is from the London Cycling Campaign. I also forgot to say that Hackney and Walthamstow Marshes are a great place to cycle: loads and loads of green space and pubs along the canal - you can even go all the way up to Tottenham.
