The String bike
Hi,
Saw this reviewed on Wired magazine gadget site. Looks fascinating. 18 speeds and no chain. http://www.wired.com/reviews/2012/02/stringbike/ http://www.stringbike.com/ |

If it is close in weight, and as efficient as a chain, looks like a good idea. Maybe not conceptually simple as chain and sprockets. But not rocket science once it is worked out.

Cool, but I'll bet my old cotter-cranked Peugeot that the drivetrain efficiency is much lower than a chain-drive.
But that doesn't mean you can't ride it to the coffee shop. |

Well,, the part that got me was 'springs in the hub help you pedal uphill'. Umm... last I heard, there ain't no free lunch.

The bicycle meets Rube Goldberg
Ah, a design to make Rube Goldberg would be proud. Rotary motion is converted by a cam system into a lever motion, which in turn powers a reciprocating cable and pulley, and the cable is wound around a bobbin to convert it back to rotary motion. Brilliant!
Clearly this the next evolutionary step beyond the Alenax drive. |

IMO this is just like a bamboo bike - you get it to be different.

It looks like that bike will make you hip and popular!
I want to know where to get one of those fedora shaped helmets, that's style, BABY! |
