List of bicycle parts by alphabetic order: Axle : as in the generic definition, a rod that serves to attach a wheel to a bicycle and provides support for bearings on which the wheel rotates. Also sometimes used to describe suspension components, for example a swing arm pivot axle
Shaft drives operate at a very consistent rate of efficiency and performance, without adjustments or maintenance, though their efficiency has been lower than that of a properly adjusted and lubricated chain, [9] [10] possibly because of insufficiently precise machining or alignment of the bevel gears.
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.
The earliest record of a pedalo is perhaps Leonardo da Vinci's diagram of a craft driven by two pedals. [1] [2] Typically, a two-seat pedalo has two sets of pedals side-by-side, designed to be used together. Some models, however, have three pedals on each side, to allow a person boating alone to pedal from a centrally seated position.
The 1900 Singer Motor Wheel was a wheel incorporating a small ICE powerplant that could be substituted for the front wheel of a bicycle. A later design, the 1914 Smith Motor Wheel, was attached to the rear of a bicycle by means of an outrigger arm, a design later taken up by Briggs & Stratton.
Deutsche Bahn pedelecs with rear hub motors and batteries placed inside the frames.This is the "Jetstream" from Riese und Müller.. A Pedelec (from pedal electric cycle) or EPAC (electronically power assisted cycle), is a type of low-powered electric bicycle where the rider's pedalling is assisted by a small electric motor.
Further, the demise of their main engine supplier, Villiers, and the increasing number of foreign imports, spelled the end of large scale production. Burnard Wade developed and marketed motor cycle suspension units, sold spares and undertook general engineering work to keep the company viable, but always hoped to return to motorcycle manufacture.
In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic ...
