In my opinion Hubless Chopper just a new trend introduced by some daring customizer. I would say that the trend or ideas came out from TRON movie. One thing people see about choppers or harley davidson is the rims.
Maybe the hubless chopper looked strange but the trend would not last long, maybe it gonna repeat again in next 30 years? Well, Trends is not the future.
My late father told me once, Rims are like men shoes, you got to have it fit and looked nice.
