Velogical rim dynamo:
Someone buy this and report plz.

I probably will on the fixed bike.
Thought it may make a nice addition to charge your phone with.
Thinking about it, I can put it on the rear connected to a small battery in a rack.

Here as it's not bike porn and is too interesting not to post.

Looks like some kind of kill strapped under the seat there, successful rabbit hunt?

Americans are mad for their protein during rides. You could be right.

Rob Dean made a good analogy. The energy wasted in biscuits.

Isn't that assuming the dynamo perfectly converts the movement into electricity? I'm guessing he based the 6W on what the LED draws...
Just being picky, of course.

^ Chocolate on the digestive would sort that out, and the biscuit would be more yummy.

Can anyone recommend the best drop levers to use with standard v brakes?

These: http://www.tektro.com/_english/01_products/01_prodetail.php?pid=10&sortname=Cyclocross&sort=2&fid=3
Or you can buy the Cane Creek ones which are allegedly made in the same factory but with a textured hood and cost twice as much...

I saw those but also read some dodgy reviews of them, do you know what they're like to use?
-

Got links?
I haven't used them so far but have a pair on order when I get a new fork.

I have the CC version. they work great with bb7 discs, though I'm not overly happy with the hood shape and feel. Or rather the shape of the body beneath the hood.
But I guess that's more of a subjective, ergonomic concern. -

I don't know where to put this so I'll put it here. This is from a car forum I'm on:
Meanwhile, I've been rebuilding this old nail;

And incorporating a few electrical Lance Armstrongs into the bottom bracket;

It's an old Felt Q650 frame, bought for beer money last year and then stuck in a cupboard. It's been powdercoated at Maldon Shotblasting and Powdercoating in blue with a sparkly lacquer, along with some motor mounts that a guy in the States laser cut for me. The 3 phase AC motor is from a Chinese trike, the electronics that control it all and help make it legal when on the road are from a genius in Canada, and the battery will be a 60v15ah LiFePO4 unit, not as light as LiPo batteries, but a lot less likely to burn my house down...
In road legal mode, it will supply 250watts at up to 15mph for about 3 hours. Anymore power than that and it has to be type approved as a motorcycle. Off road however, you can turn the wick up a bit and if desired, ramp it up to 1800watts, or about 2.4hp, it might not sound much, but its plenty on an old push bike, and about 4 times what Lance Armstrong managed to put out even when on the strongest of performance enhancing drugs...
Should be fun then...
Finished.
60volts, 20 Amps, and despite the ridiculous amount of extra mass on board, it's still surprisingly agile. I took advantage of Boris' newfound relaxed attitude to bikes on public transport this afternoon, and used the riverboat service, DLR and the cable car to explore a little of Greenwich, Canary Wharf, and the Royal Docks. Power level is selectable from legal 250W mode to 1.2kW, with a future option to up the current to 30Amps. Range and top speed yet to be explored...

Heavy bike with lots of power? Needs big brakes then... 6 pots from Hope...
