Quick answer
A fan bike is a stationary bike with a large fan attached to the front wheel. The fan creates resistance as you pedal, making the exercise more difficult and intense. It is also called an air bike or an assault bike.
- Riders use both the handlebars and the pedals, and the fan adds natural resistance.
- Types include standard, big, small, and dual action fan bikes, plus models with a display screen.
- Consult a licensed doctor and a personal fitness trainer before starting an exercise regimen.
One of the most popular and oldest types of exercise machines is known as a fan bike.
What is a fan bike?
A fan bike is a stationary bike that has a large fan attached to the front wheel. This fan creates resistance as you pedal, making the exercise more difficult and intense. Harvard Health lists moderate stationary cycling at 210 to 294 calories per 30 minutes, depending on body weight.
This is your ultimate guide to fan bikes.
What Is a Fan Bike? (Detailed Explanation)
A fan bike is a stationary machine that you can ride.
You turn the handlebars and pedals to make it go. The whole thing has a large fan on the front wheel. As you pedal, the fan creates natural resistance, making it a more challenging and effective exercise.
A fan bike is also called an air bike or an assault bike.
One of the best-known fan bikes is the AirDyne, made by Schwinn.
Types of Fan Bikes
There are a few different types of fan bikes. The differences usually come down to size and features.
To truly answer the question, “What is a fan bike?” it’s essential to know the types.
Major types of fan bikes:
- Standard fan bike
- Big fan bike
- Small fan bike
- Dual action fan bike
- Fan bike with display screen
Standard Fan Bikes
A standard fan bike is around 40 x 30 x 40 inches in size.
It’s made of alloy steel and weighs approximately 60 pounds. A good example of this type of fan bike is the Marcy Fan Exercise Bike.
Big Fan Bikes
A big fan bike is any air bike bigger and heavier than the standard version.
A good example of a bigger fan bike is the Octane AirdyneX.
The Octane specs:
- Length: 55 inches
- Weight: 113 pounds
Small Fan Bikes
A smaller assault bike is around 44.5 x 23 x 48 inches in size.
Or, anything smaller than a standard-size air bike. It weighs approximately 40 pounds and is made of steel alloy.
A good example is the Body Rider exercise fan bike.
Dual Action Fan Bikes
Dual-action fan bikes have both a wheel with pedals and two push/pull levers.
This setup gives you a more varied workout. You work with different muscle groups with each type of movement.
Fan Bike With Display Screen
Some fan bikes come with display screens that show your progress and stats.
This can include things like heart rate, calories burned, time, speed, and distance. Display screens might also offer different intensity workouts.
The Schwinn AirDyne AD7 is an example of a fan bike with a display screen.
Note: Console power varies by model. Schwinn says the AirDyne AD7 console takes 2 D batteries, and Rogue says its Echo Bike uses four AA batteries.
What Do Fan Bikes Do?
Fan bikes provide a great cardiovascular workout.
If your assault bike comes with hand levers, the bike also works the upper and lower body simultaneously, making them a total-body workout machine.
The function of fan bikes offers another good answer to the question, “What is a fan bike?”
Fan bikes are excellent for high-intensity interval training (HIIT).
HIIT is a type of exercise where you alternate short periods of intense activity with short periods of rest or low-intensity activity.
The American College of Sports Medicine says HIIT improves insulin sensitivity, blood pressure and body composition about as much as moderate-intensity continuous training. It also says injuries are likely to be more common than with lower-intensity activity.
How To Use a Fan Bike
When you first get on the fan bike, start by adjusting the seat height and handlebar position.
These two adjustments will help you get into the correct riding position.
Once you’re seated, grasp the handlebars and slowly start pedaling.
If you’re new to fan bikes, start with 10-15 minute workouts and gradually increase the time as you get stronger.
Fan bike workouts can be done either indoors or outdoors.
If you’re working out indoors, make sure the space is large enough to allow for a full range of motion.
What Do Fan Bikes Not Do?
Fan bikes are great, but there are limitations.
First of all, they are heavy and harder to move than some other exercise equipment.
Additionally, fan bikes are not always ideal for people who are rehabilitating an injury. It’s always a good idea to check with your doctor before starting an exercise routine.
Fan bikes are not going to result in major full-body muscle growth.
Who Are Fan Bikes For?
Fan bikes are ideal for anyone who wants a great cardio workout.
They are especially good for people who are looking to improve their endurance or lose weight.
Fan bikes are also great for people who want to do high-intensity interval training. Crossfitters, athletes, and everyday exercisers use fan bikes.
They are perfect for working out indoors on cold or rainy days.
Who Are Fan Bikes Not For?
Fan bikes are not for everyone.
You probably don’t want an air bike if you don’t want a stationary exercise machine.
They’re also not good for everyone who is rehabilitating an injury.
In particular, injuries to the lower half of your body.
Are Fan Bikes Good? (Pros and Cons of Fan Bikes)
Fan bikes are good for exercise and your health. They help with cardiovascular health, overall fitness, and weight loss.
The faster you pedal, the better the workout. There is a reason they call it an assault bike.
The more the fan blades spin, the more the fan cools you as you exercise.
Fan bikes build leg muscles, boost your endurance, and help you maintain balanced health.
Here is a chart with the major pros and cons of fan bikes:
| Air Bike Pros | Air Bike Cons |
|---|---|
| No electricity is needed for the bike | Display console needs batteries |
| Great cardio workout | Intense workout |
| Cheaper than some comparable machines | Expensive for quality bikes |
| Weight limits of 300 to 350 pounds | Heavy |
| Full body workout | Takes up space |
What Muscles Do Fan Bikes Work Out?
Fan bikes with handlebars provide a full-body workout. They work your upper and lower body muscle groups.
Here are the lower body muscles that fan bikes work:
- Calves
- Thighs
- Quadriceps
- hamstrings
- Glutes
- Hip flexors
Here are the upper body muscles that fan bikes work:
- Core
- Shoulders
- Biceps
- Triceps
- Chest
- Back
Fan Bike Vs. Other Bikes
Many people ask whether fan bikes are better than other types of bikes and exercise equipment.
This section compares air bikes with ellipticals, stationary bikes and the Peloton bike.
Fan Bike Vs. Elliptical: Which Is Better?
Neither machine is a clear winner.
Harvard Health lists a general elliptical workout at 270 to 378 calories per 30 minutes, and moderate stationary cycling at 210 to 294. Which burns more depends on how hard you work.
A fan bike’s resistance rises the harder you pedal, which suits short, hard intervals.
Ellipticals are low-impact and suit longer, steady sessions.
Fan Bike Vs. Stationary Bike: Which Is Better?
A stationary bike is also called a spin bike.
The two bikes suit different workouts.
Here are the main differences:
- Calorie burn on either bike depends mostly on how hard you ride
- Weight limits vary by model on both types of bike, so check the maker’s specifications
- Fan bike weight limits range from 300 pounds on the AssaultBike Classic to 350 pounds on the Schwinn AirDyne AD7
- A fan bike with moving handles works your arms as well as your legs
The downside is that an assault bike is heavier and more expensive.
If you want hard, full-body intervals, a fan bike is worth the money.
Fan Bike vs. Peloton: Which Is Better?
For hard interval training, the fan bike is the simpler machine. It works your arms and legs together, needs no mains power, and the fan cools you as you ride.
That means you can use a fan bike anywhere without any power source.
Well, any power source other than your body.
If comfort and versatility are your main concerns, the Peloton offers a more adjustable seat, a better display screen, and access to a massive database of Peloton workouts.
What about the price?
The Peloton bike is more expensive, and its classes need a paid membership. Check Peloton’s site for current prices.
On price, an air bike is usually cheaper to buy and to run.
Where To Buy Fan Bikes?
You can buy fan bikes at most fitness equipment stores and online at Amazon, Rogue Fitness, Schwinn, and many other places.
How Much Do Fan Bikes Cost?
Prices vary widely by brand and build. As a guide, in October 2026 the AssaultBike Classic was listed at $749, the Rogue Echo Bike V3.0 at $945 and the Schwinn AirDyne AD7 at $999 on the makers’ own sites.
As with most exercise equipment, sturdier bikes cost more.
Popular Fan Bikes
Here are three well-known models, with the maximum user weight each maker lists:
- Schwinn AirDyne AD7: 350 pounds
- Rogue Echo Bike V3.0: 330 pounds
- AssaultBike Classic: 300 pounds
FAQs for Fan Bikes
Here are answers to some of the most common questions about air bikes.
Do Fan Bikes Make a Lot of Noise?
Fan bikes are louder than most exercise bikes, because the noise comes from the fan moving air. The harder you pedal, the louder it gets.
Some newer models are quieter than older ones.
There is still some noise. They are not silent.
The volume depends on:
- How hard you pedal (as the noise originates from the fan blades)
- The size of the room
- The sound proofing of the room
If you want to make your fan bike quieter, pedal slower in a larger room with padded surfaces (such as carpet and blinds).
How Often Should I Ride My Fan Bike?
You can ride at an easy or moderate pace on most days. The American Council on Exercise says hard interval sessions should only be done two to three times a week, with at least 48 hours between them. The CDC recommends 150 minutes of moderate activity or 75 minutes of vigorous activity a week for adults. Depending on your exercise goals, you could focus on strength, endurance, or some combination.
Riding your fan bike every day can help with:
- Fat loss
- Weight management
- Getting stronger
- Heart health
- Lowers your risk for some health issues
Keep in mind that daily high-intense exercise can put pressure on your joints.
What Is a Good Fan Bike Exercise?
Some of the best fan bike exercises include sprinting intervals, speedrunning a distance, and maintaining a certain heart rate range.
These workouts are adapted from routines published by bodybuilding.com.
Sprinting intervals (8-10 Rounds):
- Warm up with a low intensity pedaling for 5 minutes
- Sprint with high intensity pedaling for 20 seconds
- Pedal with low intensity for a 30 second “rest”
- Repeat steps #2-3 (alternating sprinting and rest) 8-10 times
- Cool down for 5 minutes with low intensity pedaling
Speed run a distance:
- Choose a distance (1-3+ miles)
- Warm up with low intensity pedaling for 5 minutes
- Get to your distance as fast as possible
- Cool down with 5 minutes of low intensity pedaling
Hitting a heart rate range:
- Choose an appropriate heart rate range (60-70%, 70-80%, or 80-90%)
- Warm up with pedaling in the 60-70% heart rate range for 5 minutes
- Pedal in a heart rate range of 70-80% or 80-90% for 4-5 minutes.
- Pedal in the 60-70% range for 2-3 minutes
- Alternate step #3-4 for a total of 4 rounds/times
- Cool down for 5 minutes in the 60-70% heart rate range
Here is a good video with a 15-minute Fan bike HIIT workout:
How Many Calories for One Hour Fan Bike?
Harvard Health lists moderate stationary cycling at 210 to 294 calories per 30 minutes for people weighing 125 to 185 pounds. That is about 420 to 588 calories per hour. Vigorous stationary cycling is listed at 315 calories per 30 minutes for a 125 pound person and 441 for a 185 pound person. Harvard does not give a separate figure for fan bikes. Your own number depends on your weight and how hard you ride.
