A 2.3kg wooden bike (15lbs) by German product designer Arndt Menke. For his thesis diploma Menke studied the anisotropic properties of wood and the advantages they offer for product design. This particular frame design uses Ash wood, and is only used in places where it makes sense – instead of trying to make the whole frame from wood. The rear triangle uses a layered bridge design to create a damping area by adding a little spring. Beautiful clean design.
