The Cyclaire Hand Pump does away with convention and uses a clever push/pull system, like the hand crank of a lawn mower, to pump air. There’s a small cycle pump version and this one, which they say will inflate a full sized air bed in under a minute. Clever stuff, but do keep the defibrilator nearby just in case, won’t you? From £8.99.
Every time you pull Cyclaire’s handle, the pull-cord unwinds inside and drives a pulley mechanism. The pulley is attached to a double-ended piston, so that the piston moves backwards and forwards inside the cylinder while the pulley is turning. This is how the Cyclaire Bicycle Pump pushes so much air into the tyres; the further you pull the handle, the more times the pulley turns and the more air the piston pushes into the tyres.
