That YELLOW bike is a Modern Era "schwinn" HEAVY DUTI that has been sold for the past decade at BIKE SHOPS who carry the bikeshop grade "schwinns" which there aren't many of.

While this MODERN era "schwinn" may be slightly better constructed than the Target/Walmart "schwinns", IT IS NOT OF THE QUALITY STANDARD OF THE Real Chicago Era Schwinn Heavy Duti. Despite that, it is still a decently constructed frame.
