Six gears, one down five up.
Depends. Bicycles with external gears have chain-and-sprocket gears. Bicycles with internally geared hubs have both a chain-and-sprocket gear and spur gears (usually in a planetary configuration) inside the rear hub. Then there are the rather rare shaft-drive bicycles, which use bevel gears. And maybe an internally geared hub as well. Then there's the occasional belt drive bike of course. And one or two CVT designs.
6 gear
It depends on the brand. A lathe could be supplied with anything from two to seven separate interchangeable gears for thread cutting purposes. If you are asking how many gears a single standard center lathe has in total, the number could exceed fifty.

It depends on the bike if the engine of bike is heavy it has more gears. Usually 5 gears are max gears.
4 to 6
Depending on the mountain bike that you have will depict the amount of gears. Most bikes for adults typically have about 21 gears. If this does no answer your question then what are levels?
This bike has a six speed gear box, so six gears.

well from my experience "if understand the question correctly" take the number of gears on the back derailleur and multiply that number with how many gears are on the front derailleur
Depends on the make and model of the bike. Some motocross bikes have 4 gears while most of the cross country thumpers are 5 or 6 speeds.
