Internal gear hubs on 3-speed bikes are preferred by cyclists, because they are more reliable and more practical than derailleur systems. The latter became extremely popular in the latter part of the 20th century, making manufacturers produce less and less bikes with internal gear hubs.
Cyclists who prefer internal gear hubs are happy with the system's easy maintenance quality. They're also satisfied with the way it allows them to go smoothly in a stop-and-go traffic, that's quite a problem with a derailleur system. Riding using the middle gear is a favorite for many cyclists, as they can feel no drag from any derailleur pulleys.
Almost all the benefits of a 3-speed bike with an internal gear hub are due to the planetary gearing that it has. It is called planetary since the components are arranged as if they are the planets of the solar system. The core gear or the "sun" is attached to the center of the axle. 3 or 4 identical gears or "planets" revolve around the "sun." A gear ring, with its teeth on the inside, surrounds these planets.
The planets are also attached to a planet cage. In most models, as the planet gears go around the sun, the gear ring revolves 4 times for every 3 times the planet cage's revolution.
The 3 gears, low, middle, and high, have their own functions. When using the middle gear, your sprocket drives the gear ring, which drives the hub. This gives you a direct drive. Your internal gears continuously rotate as long as your sprocket does, but they don't affect the drive in middle gear. Put your bike on low gear and the sprocket will still drive the gear ring, but the planet cage will drive the hub. This makes your sprocket turn faster than your wheel. If you put your bike on high gear, however, your sprocket's drive will shift to the planet cage as the gear ring still drives the hub. The effect is that your rear wheel now will turn faster than your sprocket.
So what about bikes with more than just 3 speeds? They either use more planetary stages or compound planet gears having two or more sets of teeth.
Bike manufacturers have introduced 7-speeds and 14-speeds in the past years. And with the increasing demand for more advanced vehicles, these companies are continuing to address this. But for most people, the basic 3-speed bike is the practical choice.
