An indoor bike is one of the most popular pieces of home cardio equipment. It's relatively compact, low-impact for many people, quiet compared with a treadmill and easy to use while watching a class or a show. But "exercise bike" covers several very different machines, from upright bikes and recumbents to studio-style indoor cycling bikes with heavy flywheels and connected screens.
This guide explains the main types and what to check before buying. It doesn't rate bikes or make claims about fitness outcomes. For published prices and specs, see our home gym comparison. Talk to a qualified professional before starting a new exercise program, especially if you have a medical condition, joint problems or are recovering from an injury.
The main types
Upright bikes
Upright bikes have a seat positioned over the pedals, a more upright riding position and often a wide, padded saddle. They're usually simple to use and take up modest floor space. Many have built-in programs and a basic console.
Recumbent bikes
Recumbent bikes have a chair-like seat with a backrest and pedals out in front. The reclined position supports the back and can be easier to get on and off. They're often chosen by people who want more support, though they usually take up more floor length.
Indoor cycling bikes
Indoor cycling or studio-style bikes mimic a road bike position, with a narrower saddle, adjustable handlebars and a weighted flywheel. They suit people who want class-style workouts, standing climbs and intervals. Many pair with streaming classes, either on a built-in screen or through a tablet or phone. See choosing a fitness streaming app.
Air bikes
Fan bikes use air resistance and moving handles. They're covered separately in air bikes explained.
How resistance works
- Magnetic resistance uses magnets near the flywheel. It's typically quiet and low-maintenance, and resistance can be adjusted with a knob or electronically.
- Friction resistance uses a felt or leather pad pressing on the flywheel. It's often found on lower-cost indoor cycling bikes, can feel smooth and allows fine adjustment, but pads wear out and may need replacement.
- Fan or air resistance increases as you pedal faster. It's louder and creates a breeze.
Flywheel weight is often listed, but it's not a direct measure of quality. Ride feel depends on flywheel design, gearing and resistance system. If you can, try a bike before buying, or check the return policy.
Fit and adjustability
A bike that doesn't fit is uncomfortable and may stress knees, hips or back. Check:
- Seat height range and whether it fits your inseam. Published rider height ranges help, but inseam matters more.
- Fore-aft seat adjustment on indoor cycling bikes, which lets you position knees relative to pedals.
- Handlebar height and reach.
- Maximum user weight, which manufacturers list.
- Step-through design if getting on and off is a concern.
For many riders, a common starting point is a seat height where the knee is slightly bent at the bottom of the pedal stroke. Bike-fit guidance from the manufacturer or a qualified professional is worth following.
Pedals and shoes
Indoor cycling bikes may have flat pedals with toe cages, clip-in pedals for cycling shoes or dual-sided pedals. Clip-in pedals need compatible cleats and shoes. If you don't want to buy cycling shoes, look for toe-cage or dual-sided pedals. Upright and recumbent bikes usually have flat pedals with straps.
Footprint, weight and noise
Measure the floor space and add room to get on and off safely. Check the bike's listed dimensions and weight, especially if you'll need to move it; many have front transport wheels. Bikes are generally quiet, but flywheels, belts and pedaling can transmit vibration through floors. In apartments or upstairs rooms, a mat helps. See home gym flooring and noise and apartment-friendly cardio.
Consoles, screens and subscriptions
Consoles range from simple displays showing time, distance and estimated calories to large touchscreens with streaming classes. Questions to ask:
- Is a subscription required to use key features, such as resistance control, classes or even basic metrics?
- What happens without a subscription? Some bikes work as basic bikes; others lose much of their function.
- Can you use your own tablet or apps? Some bikes support Bluetooth connections to third-party apps; others are locked to one platform.
- How are metrics measured? Cadence, resistance and power numbers vary in how they're calculated. Treat estimated calories and power as approximate.

Heart rate and tracking
Some bikes have grip sensors or support chest straps and wearables. Grip sensors are often less consistent than chest straps. Our workout tracking and wearables guide explains the options.
Assembly and delivery
Check whether delivery includes assembly, how heavy the box is and whether you'll need a second person. Some brands offer paid setup. Keep the hardware list and manual.
Maintenance
Bikes need some care: wipe sweat off frames and consoles, check bolts and pedals periodically, and follow the manufacturer's schedule for belt, pad or other maintenance. Our caring for home gym equipment guide covers routines.
Warranty and returns
Read the warranty for frame, parts and electronics, and check the return window and any restocking or return shipping fees. These details vary widely and matter more for large items.
Planning your first few weeks
A new bike is easy to overdo. Many people start with shorter, easy rides a few times a week and build gradually, adding time before intensity. Set the seat and handlebars before the first ride, write the settings down (or mark the posts with tape) so every household member can return to their own fit quickly, and keep a towel and water within reach. If a streaming class is too hard, it's fine to lower resistance or ride at your own pace; the instructor can't see you. Note any knee, hip or back discomfort and recheck fit before pushing through it. Our weekly routine guide shows how to fit rides around other workouts.
FAQ
Is a recumbent bike easier on the back?
Many people find the backrest supportive, but individual needs differ. Ask a qualified professional if you have back problems.
Do I need clip-in shoes?
Only if the bike's pedals require them. Many bikes offer toe cages or dual-sided pedals.
Is a heavier flywheel better?
Not necessarily. Ride feel depends on the whole design. Try one if you can.
Bottom line
Choose the bike type that matches how you want to ride, check fit and adjustability for your body, understand the resistance system and subscription requirements, measure your space and plan for noise and maintenance. Compare published prices and specs in our home gym comparison.
