Rowed vehicles
Encyclopedia
A rowing cycle is a wheeled vehicle propelled by a rowing motion of the body. Steering, braking, and shifting are usually done by the handlebars. Feet are on symmetrical foot rests, as opposed to rotating pedals. Unlike many rowing boats

Watercraft rowing is the act of propelling a boat using the motion of oars in the water. The difference between paddling and rowing is that with rowing the oars have a mechanical connection with the boat whereas with paddling the paddles are hand-held with no mechanical connection.This article...

, the rider faces forward. Rowing cycles exist in numerous designs, particularly with respect to frames and drive mechanisms. Commercial production numbers for rowing cycles are small compared to that of standard bicycles.

History

The use of a rowing-like action to propel a land vehicle goes probably to the 1870s, as George W. Lee used a sliding-seat in a tricycle . In the 1920s, Manfred Curry in Germany designed and constructed the Landskiff ("land boat"), a four-wheeled vehicle that would be known as a Rowmobile in the english speaking countries . A newsreel

 from 1937 shows a rowed bicycle that is very similar to today's Craftsbury SS rowing bicycle, Rowbike and VogaBike.

Propulsion and steering

Some rowed vehicles use a stroke similar to a boat, in that force is used only when straightening the body, the drive portion of the stroke, not the recovery. Other rowed vehicles, mostly those that use linkages and crankshafts in their drive trains, use force in both straightening and bending the body. On most, the handlebars move; most also have moving footrests and some have a moving seat.

The handle bars on some rowed vehicles travel on a semicircular path due to the handlebars being mounted to a fixed length lever pinned to the frame. Some attempt to simulate the more level stroke used in rowing a boat, for example Streetrower and Vogabike. Streetrower has "the most natural rowing action of any rowing vehicle to date".

The Street Rower uses a steering system actuated by servos and controlled by the rider with a joy stick.

Drive train

Rowed vehicles generally have one of three drive trains: chain, linkages, or cable.

 on the other. As the rower pulls back the chain engages the rear cog and the bungee cord is extended, and when the rower returns forward the bungee cord contracts, pulling the chain back and ensuring there is no slack in the chain. All Rowbikes have a rear derailleur, even single speeds, due to the need to keep proper tension in the chain.

Rowbikes that use linkages include Champiot and Powerpumper. They use linkages connected to a crank shaft, similar to a pedal car.

The Thys Rowingbike and Streetrower use a cable which coils and uncoils about a spool. Thys calls his version a snek drive.
