Working at a university, we might have a couple of thousand bikes on campus at any time. I've been seeing some odd off-brand numbers lately, mostly of Asian manufacture. There are a couple of aluminum-framed folding commuter jobs, copies of standard designs from Europe. They appear to be of decent quality.
Also a number of cheap, flashy-looking roadsters. These tend to have wild paint jobs and anodized-in-color rims, frequently matching the frame paint. Low-end Shimano components, bolt-on wheels, that sort of thing.
Saw one yesterday that sported a "GMC" brand. A fairly nice-looking roadster, till you got close. Semi-aero rims, aero brake levers, and gripshifters! Yes, they had somehow gotten a pair of Shimano twist-shifters onto the top section of a standard drop bar. Unusual. Frame was all aluminum, but most likely a poor alloy, the dropouts looked to be about 1/4" thick.
No doubt the rapidly-expanding industrial power of China will continue to look for products to sell, and they have a huge bike industry.
Hehe- looked it up...available at walmart:
