...unless, of course, you have more then one bike. Seven bikes, seven wheels, and seven lights since the E-delux doesn't look like it comes with a quick release. I'll cut it back to 5 bikes because I don't really see using a couple of the bikes at night. At $178 each for the light, that's $890 for the lamps. With 2 disc brakes and 3 rim brakes that's $1340 for hubs and another $300 for rims and another $160 for spokes (I build them myself). That's $2690 which is a serious chunk of change. I, too, will keep charging batteries.

Additionally, even one SON hub, E-delux headlight and B&M Toplight is way over mysta02's $100 budget. Any hub based system is way over his budget and a bottle generator system is, well, just wrong.
