Whizzer bicycle engines are a line of bicycle engines that were produced in the United States from 1939 to 1965. They were commonly sold as kits to be assembled and attached to a consumer's bicycle thus creating a motorized bicycle. Whizzer U.S.A. re-appeared in 1997 to sell an improved version, pre-assembled on an old Schwinn-style bicycle frame.
A VéloSoleX motorized bicycle. A motorized bicycle is a bicycle with an motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit ...
Four-stroke engines are the most common internal combustion engine design for motorized land transport, [1] being used in automobiles, trucks, diesel trains, light aircraft and motorcycles. The major alternative design is the two-stroke cycle .
Motorcycles with a V-twin engine mounted with its crankshaft mounted in line with the frame, e.g. the Honda CX series, are said to have "transverse" engines, [1] [2] while motorcycles with a V-twin mounted with its crankshaft mounted perpendicular to the frame, e.g. most Harley-Davidsons, are said to have "longitudinal" engines.
A Honda Super Cub engine. The most popular motorcycle in history, with over 100 million produced. A motorcycle engine is an engine that powers a motorcycle.Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.
A race kit is available from the manufacturer that boosts power from the standard 15 bhp to 25 bhp. [ 5 ] The RS4 125 is available with a quick-shift system similar to the RSV4 , in which the engine halts the torque from the engine based on engine rpm, the amount of throttle being applied, and the speed of the bike.
What could be argued is that the Genesis concept (not just the inclination of the engine, although on the FZ750 was a radical 45 degrees, on the FZR1000 a less radical 35 degrees, a feature now generally universally used in the modern (post 1990) sport bike thus allowing downdraft air induction and airbox pressurization, but also the use of ...
The idea for the engine was rejected by BSA, but adopted by Ariel. Thus it became the Ariel Square Four. In 1966 Phil Vincent wrote in Motor Cycle: "Alas, in 1959 the Square Four went out of production, a victim of the modern trend towards small, high-revving modern power units. The demand had tailed off a bit, and with reduced output, the ...
