Dicycle Otto, from England, 1881 and 1886
The only way to increase the speed of a bike is to increase the size of the wheels on which the pedals have been mounted. On a dicycle, you are sitting between two large wheels. The third, small wheel is only useful for fall prevention. For riding the bicycle, or even mounting it, the art of balancing is a prerequisite. The brake must be pushed in to be able to mount safely. You can steer the bike by turning the handle.
