Electroluminescent (EL) wire that glows when AC current is applied to it.
An old stepper motor to provide variable AC power
An old cell phone charger wired in reverse to convert low-voltage produced by the motor to high voltage required by EL wire.
The result: a bike that changes in brightness (and even its color, a little) depending on your pedaling speed, a little bit reminiscent of a TRON lightcycle. In the below video, the TRON bike maker is on a swing bike so it looks kind of funny, but you get the idea.
View full instructions at Instructables, and be careful not to shock yourself with this project. Unless you’re into that kind of stuff.
Michael Mann of Boston University was inspired by the various bamboo bike mentions, but was frustrated he couldn’t find a How To. So he started a blog chronicling the steps he took to build his own bamboo bicycle. In the video he talks about his project and why bamboo is a good choice for DIY bike construction.
Secure the front fork by drilling holes through the headtube and sticking bolts through so the steerer doesn’t move.
Cold set the rear bike’s front forks by spreading them out so they fit over the front bike’s rear forks/dropouts, then put the “middle” wheel in and use the rear wheel axle to hold the whole thing together.
Run a drive-side timing chain from the front bike to rear bike’s crankset. The front derailleur is removed, of course, as are both derailleur’s from the captain’s bike.
The drive chain is run from the rear bike’s other chainring to the rear bike’s rear derailleur.
