Front-wheel drive and two-wheel drive systems can be implemented. (See two-wheel drive) Drive can double as a hydraulic brake, eliminating the weight, cost, and maintenance of regular brakes. The hydraulic (hydrostatic) transmission could be useful for recumbent bicycles because the hoses may be easier to route than a long chain.
Dynamic Runabout 7 shaft-driven bicycle Drive-shaft housing A shaft-driven bicycle is a bicycle that uses a drive shaft instead of a chain to transmit power from the pedals to the wheel . Shaft drives were introduced in the 1880s, but were mostly supplanted by chain-driven bicycles due to the gear ranges possible with sprockets and derailleurs .
Shimano Alfine SG-S700 11 speed epicyclic internally geared hub, without auxiliary components. Alfine is a comfort and urban oriented product series by Shimano.It is mainly known for internally geared hubs, but includes also hydraulic disc brakes and levers, chain tensioners, dynamo hubs, cranksets, shift levers, and complete wheels.
Common hydraulic fluids are based on mineral oil or water. [1] Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, automatic transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery.

Mineral oil is used as a laxative to alleviate constipation by retaining water in stool and the intestines. [11] Although generally considered safe, as noted above, there is a concern of mist inhalation leading to serious health conditions such as pneumonia. [12] Mineral oil can be administered either orally [13] or rectally. [14]
Most brake fluids used today are glycol-ether based, but mineral oil (Citroën/Rolls-Royce liquide hydraulique minéral ) and silicone-based (DOT 5) fluids are also available. [1] The origins of modern braking systems date back to an event more than a century ago - in 1917, Scotsman Malcolm Lockheed patented a hydraulic actuated braking system.
Hydraulic transmission may refer to various transmission methods for transferring engine power to drive wheels, using hydraulic fluid: Diesel-hydraulic transmission , used in railway locomotives Hydrostatic transmission , using hydraulic motors to convert the fluid energy into rotary propulsion
