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.
In 2010, Daimler introduced the Smart eBike, a power-electric hybrid bicycle featuring Gates Carbon drive-belt system. The eBike is designed for a clean, grease-free ride. [13] Other notable eBike brands include Grace and Pi-Mobility. In 2012, Continental AG’s subsidiary ContiTech introduced the CONTI® DRIVE SYSTEM for bicycles. [14]
The most common type of CVT uses a V-belt which runs between two variable-diameter pulleys. [2] The pulleys consist of two cone-shaped halves that move together and apart. The V-belt runs between these two halves, so the effective diameter of the pulley is dependent on the distance between the two halves of the pull
The systems were more dangerous. Down time due to mechanical problems was higher. It was not as easy to change speed. Factory layout was designed around access to the line shafts, not in the most efficient manner for the work flow. The line shafts and millwork took up a lot of space; Baldwin Locomotive Works estimated 40% more than electric drive.
The DW-link is a subset of the common four-bar system used widely in bicycle suspension. The four-bar system has been used on mountain bikes since the early days of suspension. Similar suspension systems to the DW-link have been used by Schwinn, Fisher and Karpiel. Currently a similar system is used by Giant and named "Maestro".

Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns. On some bicycles there is only one gear and, therefore, the gear ratio is fixed , but most modern bicycles have multiple gears and thus multiple gear ratios.
