The Bicycle Academy

A place to learn how to make bikes. You keep the skills, your first bike goes to someone who really needs it.

The Bicycle Academy is a new enterprise providing people with the skills and facilities to design and make their own bikes.

Frame building will be taught by the legendary Brian Curtis as evening classes or short weekday courses. As part of the learning process each student will make a frame designed specifically for use in Africa. Once graduated students will be able to use The Bicycle Academy workshop to hone their skills and build their own frames. (Sponsored via peoplefund.it)

STRINGBIKE® wires and pulleys–no greasy chains

Vodpod videos no longer available.

Developed at bike-maker Schwinn Csepel Ltd in Hungaria. The bicycle design utilizes wires and pulleys rather than greasy chains to get you around.

The “Stringbike” uses two steel cables attached to pulleys, which move on swinging kidney-shaped discs as you pedal. The discs replace a traditional round gear system, and you can install different discs depending on your needs, according to the Web site Hungarian Ambiance.

The position of the pedals determines the position of the discs, so that they swing in opposition — one is always pulling the bike forward, and the other lags behind. This allows a continuous transmission change, which could help a rider navigate winding streets, because you can more easily control the transmission without having to shift gears.
