The wheels that came on the Sidewinder were actually pretty good doubled walled, 36 hole, 12 gauge spokes, cross 3 pattern, cro-molly through axle and disc hub for a freewheel.
For a rear wheel the above description should be the minimum standards.
Optional areas would be:
Disc hub, rim or drum brakes.
Spokes or mags.
Freewheel, cassette, freehub or IGH.
