Look at her balance as she checks the road ahead, both feet still on the pedals. i sometimes try to cycle all the way home from work (6 miles) without putting my feet down. Obviously it only really works if all the lights are in my favour but it can happen (I've even named such an event "A Golden Run"). Can't imagine you could get too far in central London before a foot comes down though...
Like this processing. 6 miles with no feet down, I can't even imagine doing this. The first stop light, 10 blocks from my house, won't turn unless I get off the bike and push the walk button so I am done for right there.
I like the photo.
