Pull!

Bicycles are great for exercising the lower body, but what about the back? In 1900 Louis S. Burbank had a bright idea — by mounting a pair of sculls on the frame, the modern cyclist can row his way to total fitness.

The levers are used for both pedaling and steering. The patent says nothing about brakes.
