What does a bicycle freehub do? A freehub is a type of bicycle hub that incorporates a ratcheting mechanism. A freewheel mechanism allows a rider to stop pedalling whilst the cycle is still in forward motion. On a cycle without a freewheel mechanism, the rider has to keep pedalling whenever the cycle is moving.
Then, What is the difference between a freewheel and a freehub?
The difference between a freewheel system and a freehub system is in the location of the coasting mechanism. On a freewheel system, the coasting mechanism is built into the gear cluster. On a freehub system, the coasting mechanism is a sub-assembly of the wheel's hub.

On the other hand, Which is better freehub or cassette?
A freewheel has a lower number of gears so is better suited for casual riders who don't require the larger selection of gears available from a cassette. It's much better coasting, allowing you to rest your legs, and if done correctly, can be useful when climbing hills and easier coming down them.
How long do Freehubs last?
I had them last anywhere between two weeks and three months (170 miles per week). Eventually I gave up and bought a Shimano R500 rear wheel for £50 and six months later the freehub is still fine. If you're degreasing the cassette mounted to the bike, you're probably washing the grease out of the free hub.

How does a bicycle hub work?

Does my bike have a cassette or freewheel?
To determine if a sprocket is a freewheel or cassette system, remove the rear wheel from the bike. Spin the sprockets backwards. If the fittings spin with the cogs, it is a cassette system with a freehub. If the tool fittings do not spin with the cogs, it is a threaded freewheel system.
Can you use any freehub?
freehub standard accepts only XD cassettes. There are 10, 11 and 12 speed cassette versions (same XD freehub body). Many wheel and hub manufacturers make XD compatible freehub bodies that can be screwed onto the hub instead of the old Shimano compatible freehub.
Can I change a freehub?
You can either buy a new freehub body or if you're lucky your local bike shop or bike recycling project may have a stash! Your replacement freehub body needs to have the same interface as your old one (meaning the same spline pattern) so it can fit onto your old hub.

Do hubs make a difference?
Hubs make a huge difference when it comes to the performance of the bicycle.

What is bicycle hub?
As the part that contains the bearings, your bike's hubs allow your wheels to rotate freely. Hubs function as the center of a wheel and consist of an axle mounted in the frame of the bicycle, a set of bearings around which the wheel rotates, and the hub shell, which allows the spokes to attach the hub.
Are all Freehubs removable?
Most rear hubs allow the freehub body to be removed. However, if the bearings are worn out and require replacing, it is very likely the entire freehub is needing replacement. The blow-up image seen below is a ball bearing type freehub. The freehub pawls and bearings operate only while the bike is coasting.

What are the different types of bike hubs?
There are four types of hubs available: the track hub, the flip flop hub, the freewheel hub or the cassette hub. The recommended way to go for a fixed gear setup is to construct a new rear wheel. You can use a track hub in such an activity.

What is a free hub driver?
Freehub/Drivers are what the cassette is attached to, and this is attached to the hub with bearings and some sort of ratchet or pawl system to allow the cassette to freewheel when coasting, and then engage when you start pedaling. Each one uses a unique spline interface to the cassette.
