What is a flywheel hub?

The free wheel hub is a bicycle wheel hub including a ratchet mechanism. A set of sprockets (called "flywheel") is mounted on the splined shaft of the flywheel to mesh with the chain.

What's the difference between flywheel and hub?

The hub is the main body in the center of the wheel, including the axle. It is more or less just some bearings in a pair of cups rotating around an axis.

The flywheel is a mechanism that locks when the pedal is pressed forward (forcing the wheel to be driven by the chain) and rotates freely when sliding or stepping back on the pedal.

Both wheels have hubs, but only the rear wheels have flywheels.

These are two variants of flywheel design, taken from the Wikipedia article linked above:

Older flywheel newer flywheel

On most modern bicycles with multiple gears, the flywheel is built into the rear hub, and the whole assembly is called the flywheel. The flywheel is just a set of gears bolted together without any moving parts. It slides onto the hub and is fixed in place with a lock ring.

On older bicycles, the hub is just a hub with some threads on one side. The flywheel is built into the rear gear set and the whole assembly is screwed to the hub.

Flywheel and flywheel to flywheel

Single speed bicycles are still (usually, despite changes) made like old bicycles, with flywheel and gear integrated and screwed to flower drums.

Cassette

Since its introduction in the late 1970s, flywheel has been used in many bicycles. Starting from the high end, flywheel can also be used in cheaper bicycles over time. Today, most derailleur bicycles use this newer design. On the flywheel, the gears are inserted into the flywheel body one by one. Then fix them in place with lock nuts. They range from seven gears to 12 speeds for high-end bicycles. Usually, they are installed on medium and high-grade bicycles to give riders more flexibility in terrain and provide them with more speed options.

Free wheel

The flywheel is a gear that is screwed directly onto the threads of the rear wheels. It does not need to be installed on the hub. It usually has 1 to 7 gears, and it is difficult to find a flywheel on modern bicycles. But you do find them on some new one speed bikes. The flywheel with one gear can also be fixed, which means that you must always step on the pedal unless the bicycle is stationary. although

Flywheel and flywheel

As mentioned above, the flywheel is a set of gears on which the chain is directly installed to drive the wheels. The ratchet system is built into the block, which means that the wheel can have only one set of threads on which the block is screwed.
However, freehub has no gears. It is the hub on the rear wheel, and the snap chain wheel slides onto it. This is a component with an internal ratchet system that locks when the box is driven by a chain causing the wheels to rotate.
