STS073-355-003 (20 October - 5 November 1995) --- Doing her version of "Look, Ma, no hands" is astronaut Catherine G. Coleman.  The STS-73 mission specialist works out on the bicycle ergometer on the flight deck of the Earth-orbiting Space Shuttle Columbia.

This is a wide-angle view of the Orbital Workshop lower level experiment area. In center foreground is the ergometer bicycle. In center background is a litter chair for the Human Vestibular Function experiment (Skylab Experiment M131) and in right background is the Lower Body Negative Pressure System experiment (Skylab Experiment M092). The ergometer bicycle was used for metabolic activity experiments and exercise. The purpose of the Human Vestibular (irner ear) Function experiment was to examine the effect of weightlessness on man's sensitivity and susceptibility to motion rotation, and his perception of orientation. The Lower Body Negative Pressure experiment investigated the relationship between the zero gravity environment and cardiovascular deconditioning. A characteristic of cardiovascular deconditoning is the partial failure of the blood vessels resulting in the excessive pooling of the blood in the legs when a person assumes an erect posture in a gravity field. The Marshall Space Flight Center had the program management responsibility for the development of Skylab hardware and experiments.

STS040-211-019 (5-14 June 1991) --- Astride the bicycle ergometer, astronaut Rhea Seddon, mission specialist, breathes into the cardiovascular re-breathing unit during the exercise phase of an experiment. The investigation, In-flight Study of Cardiovascular Deconditioning (Experiment 066), was developed by Dr. Leon E. Farhi of the State University of New York in Buffalo. It focuses on the deconditioning of the heart and lungs and changes in cardiopulmonary function that occur upon return to Earth. By using non-invasive techniques of prolonged expiration and re-breathing, investigators can determine the amount of blood pumped out of the heart (cardiac output), the ease with which blood flows through all the vessels (total peripheral resistance), oxygen used and carbon dioxide released by the body, and lung function and volume changes. Measurements are made both while crew members are resting and while they pedal the exercise bicycle, as Dr. Seddon is doing here. This scene was photographed with a 35mm camera.

The small and compact workout gear will be evaluated in the orbital outpost’s microgravity environment before being used on longer term missions to the Moon, Mars, and beyond.

ISS042E082884 (12/27/2014) --- Expedition 42 Flight Engineer Terry Virts of NASA straps into the station’s stationary exercise bicycle known as the Cycle Ergometer with Vibration Isolation System (CEVIS). Each crew member spends an average of 2.5 hours a day exercising to combat the negative effects of prolonged weightlessness by maintaining bone and muscle mass and cardiovascular health.

The STS-119 mission specialist is working out on the bicycle ergometer which the crew earlier deployed on the floor of Discovery's middeck. While Acaba goes outside the International Space Station on March 21 to participate in a spacewalk, Antonelli will remain inside to contribute support, along with other astronauts and a Russian cosmonaut.

S122-E-011220 (18 Feb. 2008) --- NASA astronaut Daniel Tani (left) and European Space Agency (ESA) astronaut Hans Schlegel, both STS-122 mission specialists, pose for a photo as they float on the middeck of Space Shuttle Atlantis. A beverage container floats freely in the foreground. The shuttle's bicycle ergometer is visible at bottom center.

This Skylab-2 onboard photograph shows astronaut Charles "Pete" Conrad exercising on a stationary bicycle (ergometer) used for monitoring the metabolism of the astronauts. The ergometer was used to conduct both Vectorcardiogram experiment (M093) and Metabolic Activity experiment (M171). Experiment M093 was a medical evaluation designed to monitor changes in astronauts' cardiovascular systems, while Experiment M171 was to measure astronauts' metabolic changes during long-duration space missions.

STS109-E-5479 (7 March 2002)-- Astronaut Duane G. Carey, STS-109 pilot, takes a leisurely "spin" on the bicycle ergometer on the mid deck of the Space Shuttle Columbia, while waiting to assist Flight Day 7's assigned space walkers--astronaut James H. Newman and Michael J. Massimino. The extravehicular mobility unit (EMU) space suits of the two can be seen in the background.  The image was recorded with a digital still camera.

STS046-24-025 (31 July-8 Aug. 1992) --- Astronaut Andrew M. Allen, STS-46 pilot, exercises on the bicycle ergometer device on the flight deck of the Space Shuttle Atlantis as it makes one of its 127 total orbits for the eight-day mission. Allen, equipped with sensors for monitoring his biological systems during the run, was joined by four other NASA astronauts and two European scientists on the mission.

STS050-21-035 (25 June- 9 July 1992) --- Astronaut Ellen S. Baker, mission specialist, works out on the bicycle ergometer on the mid-deck of the Earth-orbiting Space Shuttle Columbia.  Baker was joined by four other astronauts and two scientists from the private sector for the record-setting 14-day United States Microgravity Laboratory 1 (USML-1) mission.

iss065e144326 (June 22, 2021) --- NASA astronaut and Expedition 65 Flight Engineer Mark Vande Hei sets up the International Space Station's exercise bicycle, also known as the Cycle Ergometer with Vibration Isolation and Stabilization (CEVIS), inside the U.S. Destiny laboratory module. Vande Hei later strapped himself on the CEVIS and attached sensors to himself for a workout study measuring aerobic capacity in space.

ISS010-E-25226 (20 April 2005) --- European Space Agency (ESA) astronaut Roberto Vittori of Italy is pictured in the Zvezda Service Module of the International Space Station (ISS). A patch representing the Italian flag and a toy bicycle float freely near Vittori. After spending eight days on the Station under a commercial contract between ESA and the Russian Federal Space Agency, Vittori will return to Earth with the Expedition 10 crew on April 24 (CDT).

S93-45371 (29 Sept 1993) --- Astride the bicycle ergometer, Martin J. (Marty) Fettman, DVM, breathes quietly into the cardiovascular re-breathing unit during the resting phase of an experiment.  The payload specialist for the Spacelab Life Sciences (SLS-2) mission was participating with six NASA astronauts, also assigned to STS-58, for data collection and training.
