Indoor Cycling Statistics & Data to Know in 2026

Indoor cycling sits at the center of two big shifts in how Americans train. Studio and club membership hit a record 77 million people in 2024, with boutique studios now the single largest membership category at 23.1 million members, according to the Health & Fitness Association. At the same time the connected-bike boom that defined the early 2020s has cooled, and Peloton ended its most recent quarter with 2.88 million paid Connected Fitness subscribers, per Peloton's investor relations. Behind both numbers is a simple point that riders already know. Pedaling is one of the most efficient, joint-friendly ways to train, whether the bike is bolted to a studio floor or rolling down a street.

Key Indoor Cycling Statistics at a Glance

• 77 million Americans belonged to a health club or studio in 2024, a record, and studios were the largest single category at 23.1 million members (Health & Fitness Association).

• 250 million Americans took part in at least one sport or fitness activity in 2025, the first time that mark has been passed (Sports & Fitness Industry Association).

• $2.2 billion was the global indoor cycling market in 2025, projected to reach roughly $3.2 billion by 2035 (Custom Market Insights).

• 2.88 million paid Connected Fitness subscribers remained on Peloton at the close of its fiscal third quarter, with monthly churn of 1.2% (Peloton investor relations).

• 278 calories can be burned in 30 minutes of vigorous stationary cycling by a 155-pound rider (Harvard Health).

• 47.2% of U.S. adults met federal aerobic activity guidelines in 2024, leaving most of the country short (CDC).

• Wearable technology ranked as the top fitness trend for 2026, its third year in a row at number one (American College of Sports Medicine).

Participation and the Fitness Boom

More Americans are moving than at any point on record. The Sports & Fitness Industry Association reported that 250 million people took part in at least one sport, fitness, or leisure activity in 2025, the first time that milestone has been reached. Core participants, the people who show up consistently, reached 158.8 million, up 1.2% year over year. Inactivity fell below 20% of the population for the first time.

That rising tide lifts indoor cycling. The bike is a fixture in nearly every gym, and the studio format built whole brands around it. The catch is that participation is broad but not deep. The same SFIA report found that only 32% of Americans meet the federal recommendation of 150 minutes of weekly activity, so roughly two in three fall short. For a rider, that gap is the whole argument. Getting on a bike a few times a week is one of the simplest ways to close it.

The Studio and Membership Picture

Membership numbers tell the clearest indoor cycling story right now. The Health & Fitness Association counted a record 77 million health club and studio members in 2024, about one in four Americans age six and older. Count non-member visitors and the figure approaches 96 million, close to 31% of the population. Membership has grown 20% since 2019 and rose 5.6% in 2024 alone.

Studios, the home of the packed indoor cycling class, now lead every other category. The Health & Fitness Association put studio membership at 23.1 million in 2024, just ahead of fitness-only clubs at 22.2 million. Foot-traffic data from the first half of 2025 showed overall gym visits up 3.5%, with boutique studios up a slower 0.8% and budget high-volume clubs up 3.8%. The class-based model that made spin a cultural fixture is still growing, only now it competes with cheaper options for the same riders.

Inside those clubs, the equipment mix is shifting. The Health & Fitness Association found treadmills remained the most-used machine at 43.4% of members in 2024, followed by free weights at 32.1% and resistance machines at 26.6%. Small-group training, the category that includes coached cycling classes, reached 32.3%. The bike holds its ground in a room that keeps adding options.

The growth is not evenly spread, which matters for anyone reading the indoor cycling market. Budget high-volume clubs are pulling in first-time members faster than premium studios, so the next wave of riders is more likely to meet a bike as one machine on a crowded floor than as the star of a boutique class. That widens the funnel. A rider who discovers cycling on a basic gym bike is a rider who might later want a smarter indoor setup, a studio membership, or a real bike for the road.

Connected Fitness After the Peak

No brand shaped indoor cycling's last decade like Peloton, and its numbers now read as a market correction. Peloton's investor relations reported 2.88 million paid Connected Fitness subscribers at the close of its fiscal third quarter, down from the pandemic-era highs above three million. Total revenue landed at $624 million, with connected hardware contributing $205.5 million, a sign that subscriptions now carry the business more than bike sales.

The healthier signal is retention. Average net monthly churn held at 1.2%, meaning the riders who stayed are sticking. The lesson for the wider category is that the land-grab phase is over and loyalty is the new game. People who love riding keep riding, and the brands winning now are the ones that earn a place in a rider's week rather than a spot in the garage.

The Market Behind the Bikes

The equipment market gives the trend a dollar figure. Custom Market Insights valued the global indoor cycling market at $2.2 billion in 2025 and projects it to reach about $3.2 billion by 2035, a compound annual growth rate of 3.7%. That is steadier, more grounded growth than the spike-and-crash pattern of the connected-bike years, which points to a market maturing rather than fading.

Steady demand for pedal-powered training is exactly the tailwind that carries over to electric bikes. A rider who builds fitness on a stationary bike often wants that same effort to take them somewhere, and our urban e-bikes turn indoor watts into real miles.

Why the Bike Wins on Health

The health case for cycling is where indoor training earns its keep. Harvard Health reports that a 155-pound person burns about 278 calories in 30 minutes of vigorous stationary cycling and 252 at a moderate pace, putting a hard studio class on par with running for calorie burn. Cycling does it with far less pounding on the body. Harvard describes cycling as a low-impact exercise that is gentle on the knees, hips, and ankles, which makes it a rare cardio option that heavy training will not wear out.

The wider activity data shows why that matters. The CDC found that 47.2% of U.S. adults met federal aerobic activity guidelines in 2024, with men at 52.3% and women at 42.4%. More than half the country still falls short of the movement its own health agencies recommend. A form of training that burns like running but spares the joints is well placed to help close that gap, and riders looking to add distance without the pounding often land on our fat-tire e-bikes for exactly that reason.

The joint-friendly angle also explains cycling's staying power across ages. As the population gets older, low-impact cardio stops being a preference and becomes a requirement, and the bike is one of the few tools that scales from a beginner spin to an interval session hard enough to leave a seasoned athlete gasping. That range is why cycling keeps showing up in fitness planning while higher-impact formats come and go, and it is the same quality that makes an e-bike a natural next step once a rider wants the effort to cover real ground.

Emerging Trends and What Is New in 2026

The fresh signals for 2026 point toward technology and community rather than any single machine. The American College of Sports Medicine surveyed 2,000 fitness professionals and ranked wearable technology as the top trend for the third year running, ahead of programs for older adults and exercise for weight management. Riders now expect heart-rate, power, and cadence data on every session, indoors or out, and the bikes that sync cleanly with a watch or app win the workout.

The other new entry is social. ACSM placed Adult Recreation and Sport Clubs at number nine on its 2026 list, a debut driven by people wanting fitness with connection built in. That includes community cycling clubs and group rides, the outdoor cousin of the studio class. The through-line for 2026 is that riders want data and they want company, and the strongest cycling experiences deliver both. For anyone taking that energy off the studio floor, our off-road e-bikes are built for the group ride and the long weekend loop.

Where Diesel Fits

These indoor cycling statistics describe a country that has fallen back in love with the bike, in the studio, on the screen, and increasingly on the road. Diesel Electric Bikes builds performance e-bikes for riders who want that training to carry them somewhere, with the range and power to turn a workout into a commute or an adventure. If a stationary session has you itching to ride for real, the Diesel RX-1 is where a lot of riders start.
