2. Bicycle gearing - Wikipedia

   en.wikipedia.org/wiki/Bicycle_gearing

   A single-speed bicycle is a type of bicycle with a single gear ratio and a freewheel mechanism. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle. Adult single-speed bicycles typically have a gear ratio of between 55 and 75 gear inches, depending on the rider and the anticipated ...

3. Gear inches - Wikipedia

   en.wikipedia.org/wiki/Gear_inches

   Typical gear ratios on bicycles range from very low or light gearing around 20 gear inches (1.6 metres per revolution), via medium gearing around 70 gear inches (5.6 m), to very high or heavy gearing around 125 gear inches (10 m). As in a car, low gearing is for going up hills and high gearing is for going fast.

4. List of bicycle types - Wikipedia

   en.wikipedia.org/wiki/List_of_bicycle_types

   Track bicycles, intended for indoor or outdoor cycle tracks or velodromes, are exceptionally simple compared with road bikes. They have a single gear ratio, a fixed drivetrain (i.e. no freewheel), no brakes, and are minimally adorned with other components that would otherwise be typical for a racing bicycle.

5. Single-speed bicycle - Wikipedia

   en.wikipedia.org/wiki/Single-speed_bicycle

   A great "on road" gear ratio, for the 26″ wheel, is 42:17, approximately a 2.5:1 ratio and 64.2 gear inches for versatile tour riding. Many British enthusiasts used to tour on 27–inch–wheeled lightweights on a single fixed–gear of 69 inches before multi–speed gearing became universally popular, though this certainly made for tough work.

6. Hub gear - Wikipedia

   en.wikipedia.org/wiki/Hub_gear

   A hub gear, [1] internal-gear hub, [2] internally geared hub [3] or just gear hub [4] is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and mechanism are exposed ...

7. Derailleur - Wikipedia

   en.wikipedia.org/wiki/Derailleur

   A larger sum requires a longer cage length. Typical cross country mountain bikes with three front chainrings will use a long cage rear derailleur. [citation needed] A road bike with only two front chainrings and close ratio sprockets can operate with either a short or long cage derailleur, but will work better with a short cage.
