Love the first one! Get me his number......and I'll go rob a bank!
The Kettenkrad's are not actually bikes....they were classed by the Germans as light prime-movers. 4 cylinder engine driving the tracks, with the bars operating transmission brakes to turn. Not designed to use in combat...as the fuel tanks sit either side of the rider.....
I would commute on one of those monowheels if they could make it faster!
