They can pedal faster or they can have a bigger wheel. Even for sporty people, about 100 turns a minute is the limit to how fast they can turn the pedals. A typical bicycle might have a wheel of 0.7 m, but the penny-farthing often had a front wheel of 1.5 metres (about 1.6 yards). 1 turn of the pedals moves the bicycle 3.142 x 1.5 metres forward, i.e. 4.7 metres.
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour. As schoolchildren, we learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour.
