Nice!! I've had a '79 Mongoose for a long time and finally got Motomags this year. It's just GOTTA have 'em!
Although, back in the day when these weren't collectible cruisers they were still just our bikes, the Motomags were NOT the hot setup, way too heavy!!
Most of us had a set of race wheels, usually color-anodized aluminum spoke rims and 1.75s. If we had mags we took 'em off when we had something to prove!
I ran Tuffs back in the day, lighter than Motos and they lived up to the name, I've NEVER seen a broken or damaged Tuff Wheel. I still have my Tuffs from the late '70s. My friend and I once ran over my old Team Murray (I hated that bike) wearing the Tuffs I still own in his '68 Chevy pickup, bike wrecked, wheels zero damage! But the Motomag was and is the coolest BMX wheel.
Biggest reason I didn't have 'em them was I couldn't afford them. You don't wanna know what I paid this year on eBay!
