[3] Concept2 also manufactures oars for sculling and sweep rowing, as well as two other flywheel-based exercise machines: the SkiErg[4] for cross-country skiing and the BikeErg[5] for cycling.

Their first office was in the back of a bread truck until they bought a farm in Morrisville, Vermont, United States.

[citation needed] Competitive athletes rarely refer to the machines as "indoor rowers," but use the names "erg" or "ergo" as abbreviations for ergometer.

In 1981, the Dreissigacker brothers had the idea of making an indoor rowing machine (the Model A) made mainly from bicycle parts.

At the time, the indoor rowing machines on the market cost $3,000, but the brothers (with help from friend Jon Williams) sold theirs for $600.

This sets it apart from other RowErg models and results in less body mass movement, simulating on-water rowing more accurately.

[citation needed][13] Various modern models of the RowErg are used for indoor rowing events such as BIRC and CRASH-B.

The SkiErg uses the same mechanical concept that the company's indoor rowers do, but the user is in a standing position pulling on two handles emulating the double-pole technique found in Nordic skiing.

Each pull engages the arms, shoulders, core, and legs in a downwards "crunch" making it a total body workout.

[17][18] Starting 1999, the company began facilitating a community of home-based rowers who maintain online logs hosted on the Concept2 website.

[20] Virtual teams (not based on or around a specific physical location) can be made up of anyone from anywhere who wants to participate—friends, family, co-workers, old schoolmates, rowing teammates, and so on.

Greenwich Crew from Cos Cob, CT currently holds the title of the Virtual Team Challenge, winning for three consecutive years in 2018, 2019, and 2020.
