Bicycle lights

Remember when your bike lights involved a generator powered by the rear wheel plus a ton of wire? It was time to finally replace my little bike light, so I visited our local bike shop this evening. Who knew that today's bike lights are rechargeable from a USB port?

You can get USB coffee cup warmers..

I bet that's good for the traces on the motherboard.

USB wall outlets, dude. Wave of the future.

Coming soon to a box store near you, I'm sure.

Ya know, I wouldn't mind that USB outlet in a few locations around my house.

We've started stocking little solar powered lights at the shop now. Helmet or handlebar mounted. They work pretty good, too, not gimmicky/useless like I was expecting.

Some of the bicyclists I see on my daily commute have Really Bright LED headlights, I'm impressed at how good they are.

I had one of those generators on the rear wheel of my bike when I was a kid, flipping that thing on would just about double the pedaling effort. They didn't regulate voltage to the headlight either, the light would just get brighter and brighter the faster you rode. I remember one night pedaling down a hill really fast, and the headlight burned out just before I had to make a turn.

I LOL'ed, while simultaneously hoping that no harm came to you.

I want to put something like a bike generator on my kid's go-kart, so I can run headlights which he thinks would be really, really cool!

That's right, the faster you pedaled, the brighter the light. I remember my first battery-powered bike light. It seemed so trick. I want to say it ran of D-cells.

I used to have a roommate who was really into bikes - raced semi-professionally, even welded up his own frames. On his daily rider he figured out the seat tube was just the right diameter to hold the D-cell batteries for running his lights, it made for a slick installation.

I've been reading a bit on this since I hope to get back into riding this winter (in the dark). There have been some incredible changes thanks to LED technology. I'm looking at the MJ-872 right now - terrific lighting for a fraction of what it would have cost 10-15 years ago as a halogen 'niterider' set.

I got tired of trading out lights every couple years for commuting and threw down for a generator hub. Combined with the excellent current generation of LED lights it's been maintenance free and no more charging batteries! They are bit more upfront but worth it for commuters.

one of the guys at the LBS is rocking some awesome "blinkies" that are powered by magnets...

anyway the modern LED lamps are amazing... the local MTB trial rides every wed night and some of those light kits are just WOW... here is a cheap one that is kind of what a lot of the DIY guys on the bike forums are building... lithium ion batteries give HUGE power, light weight (remember those horrid lead acid batteries?) and good power length http://www.dealextreme.com/p/mj-808-ha-iii-ssc-p7-c-sxo-3-mode-900-lumen-led-bike-light-set-44459#open%20full%20view

anyway... if you miss your generator you can get them built into your hubs now :)... no trashing your tire anymore...

You mean these are not the shizznit any more?

A young man in our Soaring club has a German made bicycle that has a dynamo in the front hub. Way better than the one pictured above.
