Hello, the knirps is really nice on pictures. But Axel, who built the krirps told me that he couldn't ride it. He experienced wheel flop. Unfortunately, the knirps has already been canibalized and rebuilt into a Zox-like lowracer. I think the crunk was too high. It's a petty he didn't discuss the issue within the mailinglist. It could have become a very good project. cheers Thomas >>> Jürgen Mages 24-03-11 21:17 >>> Hello all, yesterday I received a link to a minimalistic python-style folding recumbent: http://www.ad-bike.de/knirps.htm It is quite similar to Olaf's Monty and uses an Airbike hammock seat. The Sachs Duomatic hub has 2 gears which are shifted by slightly pedalling backwards. Cheers, Jürgen.
