Bikers, fear the flat no more — those days of cumbersome packs with oversized pumps may be behind you. In the spirit of some other resourceful bike tricks like the Aquaduct Bike and the Airbag “Collar,” Instructables shows how you can build a pump to siphon air from car tires to fix a flat — all you need is a 50-100 cm long air hose and two chucks.
