What is an air bike at a glance
A stationary bike with a fan for resistance: the harder you push and pull, the harder it gets.
Medians of the 10 air bikes we track on Amazon US, 2026-11-05.
Short answer
What Is an Air Bike: An air bike, also called a fan bike or assault bike, is a stationary bike whose resistance comes from a large fan: the faster you pedal and the harder you push and pull the moving handles, the harder the air pushes back. There are no resistance levels, so one bike covers an easy ride and an all-out sprint.
Key takeaways
- An air bike is a fan bike: resistance comes from the air and rises with your effort.
- The moving handles make it a full-body machine.
- It is loud and long, so it suits intervals more than long quiet rides.
What Is an Air Bike: How an Air Bike Works
Pedaling spins a large fan at the front of the bike. The fan is the only source of resistance, so there is no knob and no magnet: if you slow down, the load falls; if you speed up, it climbs quickly. The handles are linked to the pedals, so pushing and pulling with your arms adds to the work and spreads it over more muscles.
- Fan: turns the effort into moving air; you feel a breeze that grows with speed.
- Moving handles: they swing with each pedal stroke; some bikes also have fixed grips.
- Seat: adjusts for height and often forward and back.
- Console: shows time, speed or watts, distance and calories; some bikes add interval programs or Bluetooth.
Why Air Bikes Feel So Hard
Two things stack up. First, the resistance has no ceiling: a fan pushes back harder the faster it spins, and the drag grows faster than the speed itself, so every extra bit of speed costs more than the last. Second, the arms join in, so more muscle is working at once and your heart rate climbs fast. That is why short efforts of 10 to 30 seconds already feel intense.
It also explains why air bikes suit intervals. A 2023 study in the Journal of Strength and Conditioning Research had 32 active adults train for four weeks on a stationary air bike with short sprint intervals or moderate riding; all groups improved their maximal oxygen uptake. It was small and short, so read it as a sign, not a promise.

How to Use an Air Bike
- Set the seat: your knee keeps a slight bend at the bottom of the stroke.
- Start easy: a few minutes of light pedaling lets the fan spin up and your body warm up.
- Push and pull: drive with the legs and use the handles; keep the shoulders relaxed.
- Use intervals: hard for 20 seconds, easy for 40 seconds is a common start; see our air bike workouts.
- Give it room: the fan needs space to move air, and the bikes are long.
Who an Air Bike Suits (and Who Should Skip It)
- Suits: people who like short, hard intervals, want arms and legs working together, or want one machine that scales from easy to all-out with no setup.
- Skip it if: you want a quiet ride (the fan is the loudest resistance type), a long seated ride with back support, or a bike that folds. Try a spin bike or read spin bike vs exercise bike.
- Activity targets: the CDC count 75 minutes of vigorous activity a week as equal to 150 minutes of moderate activity for adults, and hard air bike minutes count toward the vigorous total.
What Is an Assault Bike?
“Assault” is the name of one air bike brand that spread through gyms, and many people now use it for any fan bike. In how it works, an assault bike and an air bike are the same machine. Our best air bike ranking lists the models sold on Amazon US.
