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.

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.
