Diavolo performing his bicycle daredevil act (1905)

Here’s a crowd watching Allo “Dare Devil” Diavolo riding a bicycle upside down doing a loop and topsy-turvy somersault:


Diavolo coming to “Loop the loop” (1902)

A B: Short arc, to ease the downward momentum for the climb.

B C: Long, gradual rise, so designed to miminize the outward pressure greatest in this arc.

C D: Half circle, made small so that the wheel may get past the apex with the least possible expenditure of force.

D E: Wide downward art giving the least possible momentum on leaving the loop.

E F: Gentle slope to the ground.
