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 the case of delta tricycles, the drive is often to just one of the rear wheels, though in some cases both wheels are driven through a differential. A double freewheel, preferably using no-backlash roller clutches, is considered superior. Trikes with a differential often use an internally geared hub as a gearbox in a 'mid drive' system.

The gearbox is usually incorporated into the frame near the crank , and it may be used in addition to or instead of derailleur gears or a hub gear . [ 3 ]

This gives the cycle the ability to tackle steep slopes and permits handcycle mountain biking. The addition of a wider tire with suitable tread makes some mountain biking possible on standard road bikes.
