The BMW R75 and Zündapp KS750 heavy off-road motorcycles were designed specifically for military use with large off-road tires and a motor sidecar, as well as increased ground clearance, plus front and rear gears were first put into service by the Wehrmacht in 1941. Stroller and transmission for off-road use, they also included features such as handles and footrests heated with warm air, just like the stroller, which was well received in the Russian winter.
Lion Roar has released the first of two announced German WWII motorcycles with a Zündapp KS750 sidecar kit, soon to be followed by a BMW R75 sidecar.
Two separate kits were released: Kit #L3507 with a Zündapp KS750 without sidecar and #L3808 which includes a Zündapp KS750 with sidecar and a choice of two trailers. But it should be noted that the Zündapp KS750 was never produced in the factory without a sidecar, which was also actuated by a differential from the rear wheel of the bike.
There may have been suitable field modifications to create a self-contained cycle, but all the wartime photos I've seen show the official bike and sidecar configuration.
The L3507 kit actually includes two Zündapp KS750 cycles with kit #L3508, one cycle with sidecar plus two alternative trailers, and the comments here on the cycle apply to both kits.
