Having sadly lost my electra rear wheel when it was being transported (left on the side of the road) I am now looking to replace it. I have been offered a wheel W M 3 -18 is this the correct one I think it came from a Commando. Thanks Bryon
The commando hub is similar…

Electra Wheel Rim
Normal fitment for the Electra is WM2-18 - WM3 is wider.
WM2 inside 1.85" (47mm) outside 2.72" (69mm)
WM3 inside 2.15" (55mm) outside 3.080" (78.2mm)
There is not much space to the left of the tyre (3.25 x 18) between it and the mudguard, so stick with WM2, and use an old fashioned 'square looking' tyre. A modern one may rub on the mudguard.
Czech company Mitas make exactly the right tyre:

As for rim offset - it will be trial & error - the tyre sits halfway between the suspension units, and a bolt up Commando hub will do the job. The Electra brake drum is the same as Domi/early Commando - but with a thinner chain wheel welded/brazed on. Sprocket = 52T, chain is 1/2" x 0.305 x 120links.

On my other Electra I have fitted Road riders 100/90-18 on the back 90/90-19 on the front I find them very good on hardtop poor for off road. The clearance is ok with these sizes. The problem is I bought 2 of the same for this bike. I am now left with the front one. Would the road rider R-R tire 100-90 fit on a W M 3 rim apart from clearance problems. Also is the spindle the same size.Thanks Bryon

Commando rear rim was 19 x WM2, more likely an Atlas wheel with cycle threads not unf on the hub.

The commando hub is similar so can probably be made to fit ,however only someone who has fitted a wm3 rim with tyre to an Electra would be able to confirm clearance for it to work (not me!)
