Chainless Bicycle

[krebs303]

A Hungarian design team has unveiled a new chainless bike, powered by steel wires, that easily disassembles and can be organized for touring or racing.

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,

I seen a Treck carbon everything with a rubber belt to drive it .

always wanted a bike with a rubber band to wind up.

Kinda like what Cancellara had? That's why you couldn't hear the motor you know. He just had a spring wound up and then released it for the attack.

the motion looks weird but it appears to be working fine... somehow looks a bit more fragile to me than a standard chain bike...

fixed drive shaft on a bike works fine too if you dont want too use a chain,

but it would be a lot safer if hipsters start using this

looks like a lot of places you could pinch toes or fingers
maybe it's the answer to a question nobody asked

I liked the rotating quick release on the front wheel in the animation. That and it was on the wrong side too.

A Hungarian company called Skyex has invented the StringBike — a bicycle that uses wires and pulleys instead of a chain. Here’s how it works:

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.

Ya think? I think this is a rehash of a design from about 1890. Doesn't mean it wouldn't be a good idea today, but just sayin'.

Ironically, I think the point that keeps getting missed, by a lot of ppl, is that the diamond frame and derailleur system actually works pretty well, and has significant advantages over competing concepts.

Everything is based off of string theory, its finally makings way into cycling

As opposed to a chain and gears with no cover, you'll never pinch/mangle anything in there
