Here is a picture of my M20 i am building to look if it all fits and how complete it is. I fit my spare backwheel with 18 inch rim and a 400 tyre the other original 19 inch have new bearings and needs a 19 350 tyre I try to put as much as i can original bolts and nuts on it that i collect over the past years. Later more. GR Theo

I have seen pre war parts book listings for M20 showing both 18" & 19" wheels.
The 18's may well only be for intended sidecar fittment but some must have left the factory with 18".

I believe 18s were sometimes used on sidecar outfits and I have an original 18inch rear wheel, but I have never seen a front.

Same here, ive not seen one but had a quick look at original 1938 parts list it shows a 18" complete front wheel for M20 66-5493 (the 3 might be an 8) & an 18" rim seperately 66-5494
Along with the 19" items aswell.

Still hoping and keep my fingers crossed it will be a WM20 Theo......would be good for the balance between civillian and military bikes on the 'Veluwe'....
