* Physical movement: The wheel itself, if set in motion, would physically rotate. However, the work is intended to be static, with the wheel suspended from a stool, and the wheel itself is typically not spun.
* Visual movement: The wheel's position and the play of light and shadow on its spokes could create a sense of implied movement, even when stationary. The artist intended to emphasize the perception of movement, rather than the actual motion.
* Conceptual movement: The key to understanding the movement is in the context of Duchamp's artistic practice. He was pushing against traditional notions of art and beauty, and was interested in questioning the very idea of "art" itself. The "Bicycle Wheel" is a readymade object, taken from everyday life and presented as art. This act of elevating an ordinary object to the status of art was intended to challenge our perceptions and create a sense of intellectual and conceptual movement.
So, while the "Bicycle Wheel" might not literally move, it is a work that encourages us to move our minds, to think differently about what constitutes art, and to consider the possibilities of movement beyond the physical realm.
