Depends on the type of hub. For proper fixies you need a lockring tool(although hammer + drift punch can work) and a chain whip. For single-speed bikes you need a freewheel puller, there are a couple of different versions available.
Many internally geared bikes have the sprockets sitting on splines and held in place with a circlip, for these all you need is a thin bladed screwdriver or two.
For removing the cassette of a freehub bike you need a chainwhip and a splined lockring tool.
That depends on what type of hub it is. Some simply use a spring loaded circular clip. some are threaded on and then use a threaded lockring, some are merely threaded on. You might even have several sprockets(known as a cassette) in which case the sprockets are slid on and held in place by a lockring. Or it might be a freewheel, which is simply screwed on.

Depends on the design of the hub, there areseveral options available. Many needs a special splined tool to be removed.
Depends on what part you mean, and the design. If you're asking about the rear sprocket, (cogs engage other cogs, sprockets engage a chain) I can Think of at least Three different options.
Most internal-gear hubs and some Coaster brake/Single-Speed hubs use a circlip and a splined sprocket. Pry the circlip off with a couple of small screwdrivers and the sprocket will lift right out.
Fixies use a reverse-thread lockring. It should be removed using a hook wrench, but can be removed with a hammer and a drift punch.
Some Single-Speeds use a screw-on freewheel. Real cheap ones aren't meant to be neatly removed and have to be disassembled and then the core removed with a pipe wrench. Better ones can be removed by using a special puller tool bit. There'll be a number of notches around the axle that can engage tabs on the appropriate puller, and then the freewheel can be unscrewed. Remember that pedalling torque tightenes it down so they can be on wickedly hard. Putting the puller in a bench vise, then using the Wheel for leverage is a favourite method of getting them off. A hard left will do the trick.

What is the process for bike sprocket replacement?
To replace a bike sprocket, you will need to first remove the chain from the sprocket. Then, use a wrench to loosen the bolts holding the sprocket in place. Once the bolts are removed, take off the old sprocket and replace it with the new one. Secure the new sprocket in place by tightening the bolts. Finally, reattach the chain to the new sprocket.
What happens when you have a small sprocket?
First you need to be clear about what you're talking about.In regular Bike-speak, sprockets go at the rear, and chainrings/chainwheels go at the front.In BMX-speak, a sprocket goes at the front, and a driver goes at the rear.If you're speaking BMX, the most obvious difference is the size, the tooth count.For the same size driver, a bigger sprocket will make the bike slower off the start, but give it a higher top speed.For the same size driver, a smaller sprocket will make the bike quicker off the start, but give it a lower top speed.If you change the driver to match, start and top speed will remain the same, even with a smaller/bigger sprocket. A small sprocket will increase the ground clearance. Better if you're riding ramps as there's less risk of the sprocket/chain hitting the lip as you drop in. If you're not riding ramps, well, a smaller sprocket is still lighter, which is a kinda-sorta advantage. The downside is that the smaller they get, the faster they wear. And the chain wears too.

The downside is that the smaller they get, the faster they wear. And the chain wears too.Changing to a smaller sprocket on the rear will make your bike heavier to pedal. If you're strong enough to keep cranking at the same speed as before, then your bike will be faster.
What is a good sprocket ratio for very high acceleration?
A good sprocket ratio for take off is 3.0:1 and up like 16/48 combination will have you pulling up in first.
What is the best drive sprocket removal tool to use for removing a stubborn sprocket from a motorcycle chain?
A chain breaker tool is the best tool to use for removing a stubborn drive sprocket from a motorcycle chain. It is specifically designed to break and remove chain links, making it easier to take off the sprocket.
Remove front chain sprocket on 1983 Honda ATV big red 3 wheeler?
Take off the chain and then there should be 2 little bolts holding on the sprocket. Remove those and then rotate the sprocket slightly so its teeth line up with the teeth on the output shaft and it will slide right off.
Is a small sprocket better than a big sprocket on a bike?
it would depend on whither you are riding on a mountain bike or something that wont be doing stunts or a bmx or dmr. for mountain bike it probably will not matter whither it is big or not however for bmx or dmr it would be a good idea to have a smaller one as when at skate parks eg. you where going to drop into a bowl that is quite steep if you have a big on then the chances are it is going to hit the coping (top of edge) and maybe fall off. also if you are thinking of getting a smaller sprocket you will need to get a smaller cassette but don't guess how big the cassette should be for a sprocket just take it to a bike shop and they should be able to tell you. for a smaller sprocket i would recommend a 25t to 30t,, the 25t will have to have about an 8 or 9 tooth cassette. hope all of this helps took me a while to type out anyway :P!!
