I'm well aware that aluminum alloy does not equal magnesium.. no rim is made of magnesium though, at least not entirely.
They're made of an aluminum alloy bonded with magnesium and other metals, hence the name "mag" rims.
You're right, they're probably different somehow. Except the fact that a bike rim can obviously hold the 700lbs of bike and rider while riding on the rear tire...
And the rear of a Geo Metro (especially a 3-wheeled one, even more especially if it's tapered back) DOES NOT weigh 700 lbs.
