A belt-driven bicycle is a chainless bicycle that uses a flexible belt, typically a synchronous toothed design, in order to transmit power from the pedals to the ...
A track bicycle or track bike is a form of fixed-gear bicycle optimized for racing at a velodrome or at an outdoor track. Some road racing and club cyclists use a fixed-gear bicycle for training during the winter months, generally using a relatively low gear ratio, believed to help develop a good pedalling style. [5]
A chain drive and rear derailleur gear change, the most popular system in use today A shaft-drive with crankset and rear gear hub. Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels.
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 ...
Chain drive was the main feature which differentiated the safety bicycle introduced in 1885, with its two equal-sized wheels, from the direct-drive penny-farthing or "high wheeler" type of bicycle. The popularity of the chain-driven safety bicycle brought about the demise of the penny-farthing, and is still a basic feature of bicycle design today.
Single-speed bicycles and fixed-gear bicycles have only one gear, and include all BMX bikes, many children's bikes, city messenger bikes, and many others. The fixed gear has no freewheel mechanism, so whenever the bike is in motion the pedals continue to spin. The pedals can, or sometimes must, be used to slow down.

Note that if a normal right-side-drive crankset is installed backwards to create a left-side-drive bicycle, the threaded pedal holes at the end of the crank arms would be reversed. In this configuration, precession may loosen the pedals over time, causing the pedals to become detached and/or damaging the pedal threading in the crank arms.
