A rowbike is an example of a rowing cycle, hybrid fitness/transport machine that combines a bicycle, and a rowing machine. "Rowbike" is a trademark of the Rowbike company. The Rowbike was invented by Scott Olson, the creator of Rollerblade inline skates. "Rowling" is a combination of rowing and rolling and is sometimes used in place of rowing when describing a rowbike. A rowbike is different from a bicycle in that a bicycle is powered by pedals utilizing the rider's legs, yet a Rowbike is powered utilizing the rowlers legs, back, core and arms as they engage in the back and forth, rowing motion. Rowbikes are marketed to people who desire a zero impact, total body exercise which is provided by rowing. The Rowbike works nearly every muscle in the rowler's body - as well as their mind. Although a rowbike could be classified as a human powered vehicle, as opposed to a fitness machine, rowbikes are used in the United States almost exclusively for exercise and fitness, rather than for transportation. European rowlers often use Rowbikes for commuting to work. Four wheel variants also exist, and like most bicycles, rowbikes can be used with a stand that permits use as a stationary bike or indoor rower. == Terminology == While many of the parts to a RowBike are standard to normal bicycles, there are many that are patented and proprietary to the Rowbike, and can only be obtained from the Rowbike company.〔(2006 RowBike assembly manual )〕 *Shock cord - This is a bungee cord with a loop at one end that permits the mounting, with a removable link, of a standard bicycle chain. The opposite end of the shock cord is normally knotted to prevent it from slipping into the power lever. The shock cord is located inside the power lever and is normally not visible unless the power lever is pulled all the way back. The shock cord loses its elasticity over time and needs to be replaced when this happens. *Power Lever - In the picture show it is the blue lever. The rider pulls back on the power lever to propel the Rowbike. *Swing arm - The swing arm is attached to the frame of the Rowbike in a manner that allows it to swing freely. The chain is then attached to the swing arm. *Dave Cam - The Dave cam is the pulley at the end of the power lever. *Seat Wing- The seat is mounted on the seat wings. The seat wings are brackets that have three rollers each, which permit the seat assembly to travel back and forth freely as the rider rows, the 6 rollers wear out and need to be replaced regularly. ==Propulsion and steering== Steering, braking, shifting, and propulsion are accomplished through the handlebars. The brakes and brake levers are standard bicycle components. The handle bars are specific to the Rowbike and cannot be upgraded, although standard grips, bar ends, and other accessories can be mounted on them. The front fork is controlled (or steered) with cables in a manner similar to a recumbent bicycle. The gears on the rear wheel, the shifter, and the derailer are all standard bicycle equipment. Feet are on fixed foot rests, as opposed to moving pedals. The seat, which is specific to the RowBike, slides back and forth on rollers. Unlike a boat the rider faces forward. If the rider's stroke favors the left or right side, the rowbike will pull off course, as would be the case with a boat. Balancing on a two wheeled rowbike while rowing requires some practice, even for a skilled bicyclist. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rowbike」の詳細全文を読む スポンサード リンク
