We purchased the 18" bike in blue after reading copious reviews on this and other, similarly sized bikes. The Joystar bike has a cool, retro look that is unlike any bike in the neighborhood. It is a little heavy, but the materials are good quality, contributing to a sturdy ride. My son reports that it is easy to pedal, the brakes aren't stiff and don't squeak, and the seat is comfortable. He has spent many hours riding it in the last month and a half since he received it. He is glad to have a kickstand (only available on 18", if I remember correctly). I did not assemble it, but it didn't take my husband long and he said it was issue-free. I noticed some reviews that mentioned difficult assembly, but that wasn't our experience. I would recommend.
