However, there are a wide range of freehubs available from a variety of manufacturers today. These days, since freewheels are mostly used on kid's bikes and less-expensive adult bikes, the quality level of most replacement freewheels available are pretty much equivalent. The diagram below highlights the differences between freehub system (top) and a freewheel system (bottom).

The cassette slides into place onto the freehub body and is held in position by a series of ridges, or splines, and locked in place using a cassette lockring. The gear cluster is a unit with non-moving parts, and is referred to as a cassette. On a freehub system, the coasting mechanism is a sub-assembly of the wheel's hub. The freewheel is screwed onto a set of threads on the right-hand side of the wheel's hub.

The term "freewheel" refers to the whole gear cluster with the coasting mechanism inside. On a freewheel system, the coasting mechanism is built into the gear cluster. The difference between a freewheel system and a freehub system is in the location of the coasting mechanism. When you stop pedaling, the pawls release, causing the clicking sound that you usually hear when coasting. When you pedal forward, the pawls lock into position to turn the wheel forward. Working in conjunction with these bearings is a set of spring-loaded pawls. In both cases, inside the freewheel or freehub is a set of bearings that are separate from the bearings inside the wheel's main axle.

The outward appearance of a freewheel and a freehub is not noticeably different to the average bicycle owner. Most bikes with 7 gears or less on the rear wheel use a freewheel most bike with 8 gears or more on the rear wheel use a freehub, although there are some 7-speed freehub systems in use. What keeps your feet from having to keep moving with the wheels? The answer is either a freewheel or a freehub.Īll modern multi-speed bikes use either a freewheel or a freehub system on the rear wheel, unless they are using an internally geared rear hub. Many people don't understand the inner workings of the mechanism that allows you to coast. Most people like to take a break from pedaling once in a while during their bike ride and just coast along, either to cruise down a hill or catch their breath for a few moments on a smooth, flat stretch of road.
