Again, it is not my job, neither yours, to define art. The critics in New York get to decide what is art. They were the ones who decided that the multiple avant garde movements you mention are art. Not you. Not me. I seem to understand that fact.
So if a bike is art, as you claim, prove it. Get on your bike, pedal it to any art gallery in the world, western or otherwise, ask the gallery owner to sell your bike as art. Let us know how that works out for you. Post your report here.
A gross over-simplification coupled with total surrender to art oligarchies. If I thought as you I would be too embarrassed to admit it.
