The DW-link uses anti-squat to eliminate "suspension bob." Squat is defined as the tendency of rear suspension to compress under acceleration. The anti-squat used in the DW-link system is achieved by a minimisation of torque about the centre of mass. The DW-link system has also been designed to minimise pedal feedback caused by suspension travel.
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

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.
Accelerate-by-wire or throttle-by-wire, [17] more commonly known as electronic throttle control, is a system that actuates vehicle propulsion without any mechanical connections, such as cables, from the accelerator pedal to the throttle valve of the engine or other propulsion systems. In electric vehicles, this system controls the electric ...
Six-bar linkage from Kinematics of Machinery, 1876. In mechanics, a six-bar linkage is a mechanism with one degree of freedom that is constructed from six links and seven joints. [1] An example is the Klann linkage used to drive the legs of a walking machine. In general, each joint of a linkage connects two links, and a binary link supports two ...
This was followed by various eastern European tractors through the 1970s (using manual operation via a single clutch pedal), then the Porsche 962 C racing car in 1985. The first DCT of the modern era was used in the 2003 Volkswagen Golf R32. Since the late 2000s, DCTs have become increasingly widespread, and have supplanted hydraulic automatic ...
A single dwell linkage takes advantage of the behavior of a link with a stationary revolute (hinge) or prismatic (sliding) joint and its interaction with special coupler curves. There are two methods of producing a single-dwell: arc-based and linear-based. An arc-based single dwell linkage uses the approximation of a circular arc.
Pedal spindles are hard steel, and gradually fret and erode the crankarm where the two meet. This can eventually be a cause of crank breakage, which commonly occurs at the pedal eye. Some manufacturers advise the use of a thin steel washer between the pedal and crank, but this is ineffective because the hard washer frets against the crank instead.
