"The
STRINGBIKE® has two identical but oppositely directed driving units at either side of the frame. The rotation of the pedals forces a swinging arm to swing forward and backward around its shaft. The forward segment of this motion pulls a rope wound around a drum on the rear shaft that makes the wheel to rotate. As the two sides move in mirror symmetry, there is always one arm that moves forward, thus the rear wheel is always driven. In this way the task of actual driving is taken unnoticeably from the right to the left side and vice versa."

Interesting. There are more videos on Youtube showing a real stringbike in action.
ReplyDeleteThe Hungarian origin is obvious. The motion is more complex, like a rubik cube. Hungarian Mathematics and chess players are many ... and dead. One of the highest suicide rates in the world. Just like Japan.
I like the orange background. Good marketing idea for selling at the PE site.
