This is a Fritz Riemerschmid Gleiskettenkrad (which we can assure you that we pronounced flawlessly in TLCB Office so you can too as you’re reading this), a 1930s BMW R12-based tracked motorcycle that was designed to drive on snow. In straight lines only presumably.

Built by previous bloggee Nikolaus Lowe, who seems to have a penchant for odd vintage machinery, this marvellous Model Team recreation includes a sidecar, a working two-cylinder engine with functioning gearbox, and something purporting to be steering.

There’s much more to see at Nikolaus’ ‘Fritz Riemerschmid Gleiskettenkrad’ album – click the link above to head over. In a straight line.
