the Holzweg

Arndt Menke-Zumbrägel. Holzweg, 2008Arndt Menke's wood bike uses wood as a sophisticated material, rather than a low-tech material that shows its vegetative lineage.  There is a standard set of images of the Holzweg, found on several design websites, that show its details, parts and assembly.

Laminated bentwood back wheel strut.It is possible that this too is mainly a bamboo bicycle as the photos show wood tubes for the frame pieces.  Reamed wood wouldn't be as strong as bamboo with its hollow integrity.  The most interesting part, a bentwood, laminated back wheel strut, is not, as far as I can find, discussed at all. The bentwood piece is laminated from four shaped pieces and then shaped to fit into the tubular metal lugs.  This would give it both strength and spring, giving some suspension movement in the back wheel.

We've gone through a long period of time where as individuals we have been told we can't make anything ourselves.  We certainly can't fix our own cars, where once everyone was his own mechanic.  What I like about all these wood bikes is that one could actually make one without a metal workshop, without welding equipment and a welding ticket.  These bikes are about assembly of parts, rather than sealed monolithic units, bought ready to go and only repairable by professionals.  That just seems so disengaged now.
