Send Up Your Bike Lights
Look! No, not at those hideous, atrophied monstrosities pretending to be handlebars. Look instead at that mini pump, the PUYL, which contains copper coil, a battery and an LED light. When you pump your tires, you charge the battery. It also solves the problem of where you should put your pump — in a pocket or hidden somewhere down near the bottle cage? No, it goes proudly on the top tube, shining for all to see.
It is a rather clever idea, marred by the fact that unless you ride across a river of broken glass and nails every morning you’re unlikely to keep the battery topped off enough to use it daily — even maintaining high-pressure tires in their almost rigid state requires no more than a few stiff strokes. However, as it is a patent pending design (which won designer Kai Malte Roever an award at Eurobike this year) you’re unlikely to find many people using one. Thus you can leverage their curiosity and let them give the shaft a few sharp tugs to keep the batteries full.
