Peter White Cycles PJW has been the go to guy for dynamo lighting for a long time. Because we're experiencing an expansion, and these lights are getting much more popular, you can probably find someone local who knows the stuff, but this is essential reading for the DIY folks. He also builds good wheels, and that is an understatement. This link should be over on the left there. http://www.peterwhitecycles.com/
Breezer Bikes and Bags Practical bikes and nice bags. I'm particularly fond of their Grocery Pannier and YearRounder Pannier. http://www.breezerbikes.com/
Austin's Yellow Bike Project http://www.austinyellowbike.org/ Someday perhaps I'll put up info on community bike programs. There are lots, probably one in your neighborhood. Go find it.
Oh my. This is about as sexy as bikes get: http://www.moyercycles.com/xa.htm
PaulComp's Thumbies are a super-smart item. I love Paul Components stuff, but it's vury 'spensive. http://www.paulcomp.com/
Makezine has lots of cool and useful things, like this: http://www.makezine.com/blog/archive/2007/01/how_to_add_a_le.html
Yanco Pads (and caps) are rad: http://www.yancopads.com/
NAHBS 2008 will be in Portland. I'll try to be there: http://www.handmadebicycleshow.com/
White Industries' VBC (Variable Bolt Circle) crankset is beautiful, practical, and just a damn good idea. If there weren't b'zillions of sweet old cranksets out there, I'd probably buy one: http://www.whiteind.com/VBC.html
The KHS Green Bike, interesting: http://www.khsbicycles.com/09_green_07.htm
Shimano's Coasting project is not quite as practical as I would like, but a good effort, and good intent: http://www.coasting.com/publish/content/coasting/sac/en/home.html I think we need to support the industry's efforts here, oafish though they are.
