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

   A bicycle with a 26-inch wheel, a 48-tooth chainring, and a cassette with gears ranging from 11 to 34 teeth has a lowest gear of 26 × 48 / 34 = 37 gear inches and a highest gear of 26 × 48 / 11 = 113 gear inches. For bicycles with 700c wheels, some cyclists quote gear inches based on a nominal wheel diameter of 27 inches, corresponding to the ...

7. NuVinci continuously variable transmission - Wikipedia

   en.wikipedia.org/wiki/NuVinci_Continuously...

   The NuVinci CVT replaces derailleurs and other internally geared hubs, and provides a gear ratio range of about 350%, similar to that on bicycles with 8- or 9-speed hub gears, or with double chain rings (most racing or fast road bicycles). [12] This range is somewhat less than the 526% range found on bicycles with a Rohloff 14-speed hub gear or ...
