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.
Most people are spinning between 75 and 100 revolutions per minute at a relatively light gear. This equates to around 14 - 15 miles per hour. So in a 45 minute spin class with a warm up and cool down you probably are going around 10 - 12 miles. If your really work hard and at higher gears you can average 20 miles per hour (very tough workout) and you would go between 18-20 miles per hour.
