Best Answer

Bikes with external gears are available in two different rear wheel designs. One is called a freewheel, in which the sprocket cluster together with the one-way clutch that makes coasting possblke is treated as one unit. The other is the freehub design, where the one-way clutch and the sprocket cluster are treated as separate units. With a freewheel you replace the chutch bit too when the sprockets gets worn, with a freehub you only replace the sprockets.

Freehubs also have the bearings further apart which makes them less prone to bending/breaking the axle.

Can you put an 18 gear back wheel on a 21 gear bike?

It is possible to put a 6 speed back wheel on a 21 gear bicycle but you will never be able to use more than the 6 gear allowed by that cassette sprocket.The best way to take advantage of the 21 gear bicycle is to change that 6 speed cassette sprocket and replace it by a 7 speed cassette sprocket. This way you will keep that back wheel and also be able to use all 21 gears of your bike.

How do you remove the rear gear of mongoose rebel 20 bike?

I'm assuming you're asking about how to remove the freewheel, as the Mongoose Rebel 20 is a single-gear BMX. In that case you need the correct freewheel puller to get the freewheel off. Check out www.parktools.com for more info.
