The Alloy stem point to nice (for a huffy). Check the wheels to see if they were made by Araya, or some other decent brand. I've found the in house wheels by Huffy to be ridiculously flimsy, but they did source wheels from japanese companies too.... If they have no markings just check to make sure they're true and not super wobbly (well check anyway even if they are marked).

Otherwise just make sure the hub is adjusted and oiled properly, the cables are oiled, and the bearings are greased, and you should be set.
