Square-wheeled bicycle - GIF
I think it is another fake video.
Well maybe the video is real, but the bike is fake.
1) Look closely at the junction between the spokes and the "wheels". I see the spokes. I see the "wheels" but I do not see them connect to the spokes.
2) Why is there a valve stem in the wheels since there is no air involved in this situation.
3) Bikes are a very stable platform since the two spinning wheels act a gyros to keep the bike stable. I am not certain of the physics involved with those tracks sliding along the wheels. I do not think that would provide the same stabilizing effect that the wheels would provide.
I have been wrong before. I am open to evidence it is real. But for now, for me, its is faked.
