1973 Frog by Luigi Colani


The 1973 Frog by Luigi Colani represents an intriguing exploration in motorcycle design, characterized by its unique and innovative aesthetic. This motorcycle was crafted with a rationally molded polyethylene construction, which not only contributed to its lightweight nature but also allowed for a distinctly sculptural form. The Frog's hollow design is emblematic of Colani's focus on aerodynamics, as it minimizes air resistance while enhancing the overall fluidity of the motorcycle's shape.


Finished in a striking red lacquer, the Frog immediately captures attention with its bold color and unconventional design. Colani's approach to the motorcycle reflects his broader philosophy of integrating artistic vision with functional engineering. The aerodynamic considerations of the Frog are evident in its streamlined profile, which is designed to cut through the air efficiently, improving performance and handling.


This design study showcases Colani's forward-thinking perspective, as it challenges traditional motorcycle aesthetics and encourages a reimagining of what a motorcycle can be. While the Frog did not enter production, it serves as a testament to Colani's pioneering spirit and his commitment to pushing the boundaries of vehicle design, merging form and function in a way that was revolutionary for its time.
