My eyes! They’re bleeding. Flattened by the sheer velocity of awesomeness. I often forget the times spent as a child, beating the frame of a bike into an abomination of blood-letting bliss. Jagged edges, missing spokes, lighter, faster. All you needed was a steep hill and a thick pair of Garanimal corduroys.

Jeff Tiedeken of Monkey Likes Shiny knows the feeling and he’s bringing the rawk home in the slick, clean flavor of welded aluminum. He calls it the Gravity Speed bike, a project the Aerospace welder/party animal has been working on for the better part of the year. It’s made for pure speed – no chains, cranks or pedals to hold you back. Just beautful curves and a banana seat that holds your buttocks millimeters off the rear wheel.

The bike reportedly reaches speed of 50mph, with the 80mph mark within reach. My favorite part on the bike besides everything, is the handlebar. Sleek, minimal… you might as well be hugging the head tube. You can view the speed test on Jeff’s Youtube page and keep up to date with Jeff’s adventures on his blog. If you’re interested in even more photos, check out the Gravity on the Trackosaurus Rex Flickr page.
