Dynamism of a Cyclist was painted by Umberto Boccioni in 1913 using oil on canvas, measuring 70 by 95 centimeters. Created during a period when Boccioni was deeply engaged with the principles of the Futurist movement, the work reflects his interest in capturing motion and energy in modern life. The painting was executed in Italy and is considered a significant example of his mature style, synthesizing ideas about speed, machinery, and the fragmentation of form. The composition features a figure and bicycle abstracted into interlocking geometric forms, with dynamic lines and repeated shapes suggesting rapid movement and velocity.

Vivid colors—predominantly blues, yellows, and greens—are applied in bold, angular strokes, creating an impression of swirling energy. The forms are layered and intersect, giving a sense of the cyclist being propelled forward and merging with the surrounding space. Light is rendered through contrasting areas of brightness and shadow, further emphasizing the sensation of speed. Dynamism of a Cyclist belongs to the Gianni Mattioli Collection; it hung at the Peggy Guggenheim Collection in Venice from 1997 to 2016 and has been on view at the Museo del Novecento in Milan since 2022.

The painting has been widely exhibited and is recognized as a key work in the history of Futurism. It is regarded as an important example of early twentieth-century Italian avant-garde art.
