Bike pump outside HSBC Mare street, Hackney

^ I worked at the Free Cycle Parking enclosures in Hyde Park (provided by Cyclehoop) during the Olympics, we had a pump that was for the public to use and you wouldn't believe how many people asked to use it; running your tires at ridiculously low psi seems more common than you'd think (and it was also good for people who happened to get a flat in the area and only had a crappy hand pump with them)

Same here, I worked for cyclehoop too and lots of people wanted to use the pumps we had
