Designer Kai Malter Roever has come up with a sparky little idea for cyclists — a tire pump-bike light hybrid. Just 20 seconds of pumping will (as well as toning your biceps) give the LED light attached to one end of the pump 45 minutes of illumination. Once it's charged, just fix it onto the clamp, and adjust the beam either up or down.
The PUYL (Pump Up Your Light?) is, as yet, only a concept, but it's a concept that won it this year's design award at Eurobike, and there's a patent pending on it. You can see another view of it after the jump.
