Drive Side and Non-drive Side The right side of the bike is referred to as the drive side while the left side is the non-drive side.

How to talk about gearing Gears closer to the frame are referred to as inner gears while the ones furthest from the frame are the outer gears. High and low in relation to the gears describes the relative mechanical advantage of the gearing. An easy mnemonic for this is Higher gears are harder while lower gears are easier. Also the inner gears on a bike are always going to be the lower gears and the outer gears are the higher gears.

Right-hand vs Left-hand Threading

Almost every threaded component on a bike is going to be right-hand threaded, which means that turning it clockwise will tighten it and turning it counter-clockwise will loosen it. Pedals and bottom bracket cups are examples where you would run into left-hand threaded components. To identify the handedness of a component hold it in front of you as in the picture below. The direction that the threads slant up too corresponds to the components handedness.
