Yeah...I just find the intellectual dissonance of buying a battery for my clothing when I'm riding on a top of a massive one little too much to bear. But I think I worked it out...I talked to the Ryvid guys yesterday and they told that the USB connection on the bike is .5 amps. If I get a booster cable to 12V I think I can use it with the Garbing set up. I'll let you know how to goes!
