I almost lived there! And yes, I was eager to see a docking station put in that area. Boris has said the scheme wouldn’t go up to Hampstead because the hill would result in one-way flow. Steeles Road is right at the start of the hill and there are a few decent cycle routes through that area (over the bridge, and along Queen’s Crescent, I think). It’s worth a try. The bikes are slowly encroaching on that area, so it seems a logical next step.
p.s. it’s Chalk Farm! Snob
