Rowbike

Unlike traditional bicycles, where power is supplied primarily by the rider's legs turning pedals connected to the drive wheel through a looped chain, a Rowbike delivers power through a swinging lever that moves a chain back and forth over the rear cog in a reciprocating motion regulated by a bungee cord.

Rowbikes are marketed as providing a full body workout through the rowing motion[1] which is gentle on the rider's knees, hips and back due to the system being non-load-bearing.

[2] Though Rowbike is primarily marketed as a fitness machine, as a rowing cycle it may also be classified as a human powered vehicle, as opposed to a stationary indoor rowers.

[3] As with most bicycles, a stationary bike converter stand can be obtained from a third-party vendor to allow the Rowbike to be effectively used as an indoor rower.

The front fork is controlled (or steered) with cables in a manner similar to a recumbent bicycle.

Rowbikes transmit power from the rider to the wheels using a standard bicycle chain, rear gears, and derailleur.

[6] The idea of a rowed cycle dates back to at least the 1870s,[7] and several variants have been developed commercially and sold, but there does not seem to be any evidence of a successful mass market design.

As of 2018 Rowbikes and other rowed bicycles have not found broad appeal, possibly due to their having a relatively high asking price when compared to indoor rowers.
