Professional on-board power supply
for your bicycle.
Do you forget always to load your mobile telephone. Now you can simply load your mobile telephone on the way with the bike to work (anyway 20 minutes are mostly already enough for all day long). Also on longer cycle tours you can use your portable motor vehicle navigation to the route tracking (whereby the accumulator would be flat otherwise already after 2 hours). A cool thing already is if next to your bike a convertible is at the crossroads and your Navigation systems synchronously say: "Turn off now, please". Or simply listening to music without headphones with the MP3 player of the portable motor vehicle navigation loudly.
Use this bicycle accesory kit to power USB devices (such as navigation device, MP3-player or mobiles) by your hub direct current generator.
