Dealextreme does a SSC P7 LED Bike Light Set

Or I would use something like a Cree MC-E drop in on a cheap P60 compatible flashlight with a good flashlight handlebar mount and some 18650 Lithium ion cells and charger.

I ride with a PT EOS, bike version. I actually have two - one on my helmet (or head when hiking) and one mounted on the handlebar. The one on the bike provides maximum illumination for my forward path, while I can direct the helmet mounted EOS wherever I want. This provides plenty of light for urban cycling,but I don't think it has the lumens for nocturnal single track.

Prefer the EOS because it takes AAA batteries, any style.

The newest thing in wheel generators might be the Copenhagen Wheel. So far it is mostly hype, but it might offer something worthwhile. I haven't yet found even elementary specifications for it, including weight....

I know how much the people here enjoy Altoids kits, so I wanted to add this.

I have even made a couple versions of my own.

That is impressive, rbruce, thanks for the link.

Bikes are an exercise in efficiency.

Thanks Dagny. I was going to take pictures of both my Altoids tool kits (one for my mountain bike, one for my road bike), but when I opened them up they were both filled with rust. I had them sealed with electrical tape but moisture must have gotten into them anyways. I think I am going to re-pack them into Witz cases, or something similar. I'm just bummed that I can't really share my kits with you all.

Ya my wife loves her townie. She rides that then gets on her mountain bike and complains the entire time. I cant ride hers cause it is set up (definitely) for her. But she swears by its comfort. On a separare note - we ended up on a dirt road and she said it was very hard to ride on that, but so far that is the only complaint she has had with it.

I found it at a bargain bin at my local bike store. It snaps into place and the supports attach onto my rear bike frame. The best way to describe it is it looks like an "A" coming off of the back of my bike. It is basically a gusset based design. I will try to snap a picture of it, but I can never figure out how to load it onto this forum.

I'd fix the chain and add front and back panniers...
