If you have been searching for a bike to use at home, you have probably seen the terms spin bike, exercise bike, stationary bike, indoor cycle and upright bike used almost interchangeably.
That is not entirely wrong. It is also not especially helpful when you are trying to decide what to buy.
The simplest explanation is this: a spin bike is a type of stationary exercise bike, but not every stationary exercise bike is a spin bike.
“Stationary bike” and “exercise bike” are broad terms. They can describe spin bikes, upright bikes, recumbent bikes and, depending on the retailer, air bikes. A spin bike - often called an indoor cycle or speed bike - is a more specific design intended to recreate some of the position and feel of outdoor cycling.
That difference affects how you sit, how resistance feels, whether you can ride comfortably out of the saddle, the types of workouts the bike suits and which features are worth paying for.
At Fitbiz, we help people choose equipment for everything from a spare-bedroom home gym to a commercial training facility. My advice is to ignore the label on the product page for a moment and look at the bike's actual design. The right choice is the one that fits your body, your room and the way you genuinely want to train.
This guide explains the categories in plain English, compares the main advantages and trade-offs, and uses current products from the Fitbiz exercise-bike range to show what those differences look like in practice.
The short answer
Stationary bike: The broadest description. It simply means a bicycle-style exercise machine that stays in one place.
Exercise bike: Usually another umbrella term for indoor stationary bikes. In everyday retail language, it often refers more specifically to an upright bike with a larger seat, an electronic console and programmed resistance.
Spin bike or indoor cycle: A specific stationary bike with a cycling-focused position, substantial flywheel, quick manual resistance changes and a frame designed for seated and standing efforts.
Upright exercise bike: A stationary bike with a more upright torso, comfort-oriented saddle and often electronically controlled resistance and built-in programs.
Recumbent bike: A stationary bike with a supportive backrest, pedals positioned farther forward and usually an easier step-through entry.
Air bike: A stationary bike that creates resistance with a fan, commonly using moving handles to train the arms and legs together.
If you want indoor cycling classes, faster cadence work and a road-cycling-style position, start with a spin bike. If you want a comfortable, straightforward cardio machine with programs and a conventional display, an upright exercise bike may be the better fit. If back support and easy access are priorities, compare recumbent bikes. If you want short, very hard full-body conditioning, look at air bikes.

The labels overlap because “stationary bike” describes where the bike goes, while “spin,” “upright,” “recumbent” and “air” describe how it is built. It is a little like saying sedan, family car and motor vehicle: one machine can sit inside more than one category at the same time.
What is a stationary bike?
A stationary bike is any bicycle-style cardio machine designed to be ridden without moving across the ground. The term can include:
Spin bikes and indoor cycles.
Upright exercise bikes.
Recumbent exercise bikes.
Air bikes and fan bikes.
Compact folding exercise bikes.
There is no single “stationary bike” riding position, resistance system or workout style. When a product is described only as a stationary bike, look for the more specific category before comparing it with another model.
This is particularly important online. Two products may both target the search term “stationary bike” while feeling completely different to ride. A Pure Design SB8 Magnetic Spin Bike is designed around an indoor-cycling position and manually adjusted resistance. A Bodyworx ABX450BT Upright Bike uses a comfort saddle, upright geometry, 24 levels of automatic tension and programmed workouts. Both are stationary exercise bikes; they solve different problems.
What is an exercise bike?
“Exercise bike” is also a broad term, although shoppers and retailers often use it to mean a conventional upright bike.
An upright exercise bike normally has:
A larger, comfort-oriented saddle.
Handlebars positioned to support a more upright torso.
Pedals located beneath the rider rather than well in front.
Magnetic or electronically controlled resistance.
A console with time, distance, speed, estimated calories and often heart-rate information.
Preset workouts, resistance levels or heart-rate programs on programmable models.
The important point is that an upright exercise bike is not simply an easier or cheaper spin bike. Its geometry and controls are designed for a different experience.
For example, the Bodyworx ABX450BT provides 24 levels of automatic tension, preset programs, watt and heart-rate modes, an 8kg flywheel, a larger saddle and Bluetooth compatibility with Kinomap and Zwift. Those features suit someone who wants the machine to guide the session from the console.
By contrast, a spin-bike rider will often follow an instructor or training plan, then change resistance directly with a knob while using cadence, perceived effort or power feedback to manage intensity.
What is a spin bike?
A spin bike is a stationary bike designed specifically for indoor cycling. “Indoor cycle” is the more general product description, while “Spin” began as a branded class term and is now widely used by consumers to describe the category.
Most spin bikes have:
A narrower saddle than a typical upright bike.
Handlebars that support a forward-leaning cycling position.
A prominent flywheel that helps create smooth pedal momentum.
A resistance knob that can be adjusted quickly during a workout.
A frame intended to remain stable during seated climbs, standing efforts and faster cadence work.
Seat and handlebar adjustment to help recreate a cycling position.
Toe cages, straps or clip-in pedal compatibility on some models.
The Bodyworx AIC850BT Rear Drive Indoor Cycle is a good example of a connected home spin bike. It combines an 18kg flywheel, belt drive, manually adjusted leather-pad resistance, four-way seat and handlebar adjustment, cadence feedback and Bluetooth FTMS.
The Sole SB700 Indoor Training Cycle moves farther towards a serious cycling setup with a substantial flywheel, four-way adjustment and pedals that support both SPD cleats and toe clips. At the commercial end, the Spirit SB850 adds magnetic resistance, watt feedback, Bluetooth FTMS, dual pedals and a broad published fit range.
These are all exercise bikes and stationary bikes. Their more useful description, however, is spin bike or indoor cycle because that tells you how they are intended to be ridden.
Spin bike vs upright exercise bike: the main differences
This is the comparison most buyers are really trying to make.
Riding position
A spin bike normally places the torso farther forward. The saddle and handlebars are designed to let the rider adopt a cycling-style position, shift hand positions and stand during harder efforts.
An upright exercise bike keeps the torso more vertical. The saddle is usually wider, and the handlebars are positioned for a relaxed grip rather than a road-bike-style stance.
Neither position is automatically healthier or safer. Comfort depends on the bike's adjustment range, your proportions, your mobility and how the bike is set up. A poor fit can make either style uncomfortable.
Resistance control
Many spin bikes use a manual resistance knob. Turn it slightly and the effort changes immediately. This works particularly well for classes and intervals where the rider needs to respond quickly.
Entry-level spin bikes often use friction resistance, where a pad contacts the flywheel. Magnetic spin bikes use magnets to change resistance without a pad rubbing directly on the flywheel. Magnetic systems are generally quieter and lower maintenance, although they normally cost more.
Upright exercise bikes commonly use numbered magnetic resistance levels controlled from the console. Programmable models can change the resistance automatically during hills, interval programs, watt sessions or heart-rate-controlled workouts.
Choose manual control if you like making your own rapid changes. Choose programmed control if you want to select a workout and let the machine manage the resistance profile.
Seated and standing riding
Spin bikes are designed for both seated and standing work, provided the bike is stable, correctly assembled and suitable for the rider. Standing efforts are common in indoor cycling classes and can add variety to intervals and simulated climbs.
Upright exercise bikes are primarily intended for seated riding. Some riders may briefly lift from the saddle, but the bike's geometry, pedals and frame should not be assumed to suit repeated standing efforts. Follow the product manual rather than treating every bike like the one in a spin studio.
Workout style
Spin bikes are particularly well suited to:
Instructor-led indoor cycling classes.
Cadence-based intervals.
Seated and standing climbs.
Sprint efforts.
Steady aerobic rides.
Training that resembles outdoor cycling.
Upright exercise bikes are particularly well suited to:
Comfortable steady-state cardio.
Preset hill, interval and calorie programs.
Heart-rate-controlled training on compatible models.
Watt-based programs on suitable consoles.
Beginners who want a familiar display and numbered resistance levels.
Multi-user homes where simplicity matters.
Both can deliver easy recovery rides, moderate aerobic work and challenging intervals. The main difference is how the session is controlled and how the rider is positioned.
Console and smart features
Upright bikes often provide more built-in programs at a given price. A model such as the Bodyworx ABX450BT displays time, speed, distance, RPM, estimated calories, watts and pulse, then adds user profiles and multiple program types.
Many spin bikes keep the console simpler because the rider may be following an external class on a phone or tablet. Connected models can transmit cadence, power or other workout data, but the word “Bluetooth” does not guarantee that every app will work or that the app can control resistance.
The Bodyworx AIC850BT and Spirit SB850 list Bluetooth FTMS. That is useful for compatible fitness apps, but compatibility still needs to be checked against the exact phone, tablet, app and feature you want to use.
Saddle comfort
Upright bikes usually feel more comfortable immediately because the saddle is wider and the torso more vertical. That can make the first few workouts more approachable.
Spin-bike saddles are narrower because they are designed for active pedalling and a cycling position. New riders sometimes assume the saddle is faulty when the real issue is a combination of unfamiliar pressure, poor height, excessive reach and too much time too soon.
A larger saddle is not automatically better for longer, harder cycling. It can create unwanted movement or rubbing. The right answer is a saddle and setup that suit the rider, with duration built gradually.
Noise and maintenance
A magnetic belt-drive spin bike is generally one of the quieter indoor cycling combinations. The Pure Design SB8 pairs magnetic resistance with a belt drive and is a sensible place to start for an apartment or shared home.
Friction pads create contact and eventually wear. Chain drives can sound and feel more mechanical. Upright magnetic bikes are also usually quiet, although the drive, bearings, pedals, frame and flooring can still create noise.
No exercise bike is completely silent. Use a suitable equipment mat, level the frame and investigate clicking or movement rather than turning the television up until the problem becomes someone else's mystery.
Spin bike vs recumbent bike
A recumbent bike places the rider in a supported seat with a backrest and positions the pedals farther forward. Many models have a step-through frame that is easier to enter than the higher saddle and central frame of a spin bike.
Choose a recumbent bike when your priorities include:
Back support.
A larger seat.
Easier mounting and dismounting.
A stable seated position.
Comfortable, longer-duration cardio.
Programmable resistance and console-led sessions.
Choose a spin bike when your priorities include:
A cycling-specific position.
Standing efforts and indoor cycling classes.
Fast manual resistance changes.
Higher-cadence or sprint-style training.
Clip-in pedals or road-cycling familiarity.
Fitbiz recumbent examples include the Bodyworx Deluxe Programmable Recumbent Bike, Horizon 5.0R and Sole R92.
Recumbent does not mean effortless. Resistance can still be progressed, and a well-structured session can be demanding. It simply offers a different position and support system.
If pain, balance, disability, recent surgery or rehabilitation is driving the decision, obtain advice from an appropriately qualified health or exercise professional. A product category cannot replace individual assessment.
Spin bike vs air bike
An air bike uses a fan to create resistance. On most assault-style models, the handlebars move as you pedal, so the arms and legs contribute together. The harder and faster you push, the more resistance the fan creates.
That makes an air bike excellent for:
Short, hard intervals.
Full-body conditioning.
Work-to-rest sessions.
Sports training.
Simple workouts where effort, rather than resistance settings, controls intensity.
A spin bike is usually better for:
Longer steady rides.
Indoor cycling classes.
Cadence targets.
Seated and standing cycling intervals.
Quieter training.
Riders who want a more bicycle-like experience.
Air bikes such as the Pure Design PRO10 and Bodyworx ABX7002 are not subtle at high effort. The fan produces purposeful noise, and a hard interval can become uncomfortable very quickly. That is a feature for conditioning work, not a defect.
If your ideal workout is 30 to 60 minutes of controlled cycling, choose a spin or upright bike. If your ideal workout includes 10 hard rounds with the machine matching every increase in effort, an air bike deserves a look.
Which bike burns more calories?
No category wins automatically.
Energy expenditure depends on how hard you work, how long you ride, your body size, your fitness and how much of the body is involved. A very hard air-bike interval may produce a high effort in a short period. A spin-bike class may keep you working for longer. An upright or recumbent bike may allow someone to accumulate more total training because the position feels sustainable.
Console calorie figures are estimates, not laboratory measurements. They may be more useful for comparing your own sessions on the same machine than for comparing one bike with another.
For weight loss, the best exercise bike is usually the one you can use consistently enough to support an overall energy deficit. A theoretical calorie winner that becomes an expensive clothes rack is not the winner.
The Australian Government recommends that adults accumulate moderate-to-vigorous physical activity for 30 minutes or more on most days, along with muscle-strengthening and functional activity. Indoor cycling can contribute to the aerobic component, but it should sit within a broader routine rather than being treated as the only type of movement you need. See the Australian movement recommendations for adults.
A systematic review of indoor cycling research reported potential improvements in aerobic capacity and several cardiometabolic measures, while also noting variation across training programs and study designs. That is a useful reason to ride; it is not evidence that a particular bike model produces guaranteed health or weight-loss results. Read the indoor cycling systematic review.
Which bike works the most muscles?
All stationary bikes primarily train the lower body. The quadriceps, glutes, hamstrings and calves contribute in different proportions across the pedal cycle. The trunk and upper body help stabilise the rider, particularly during harder spin-bike efforts.
An air bike with moving handles adds substantial upper-body contribution because the rider pushes and pulls while pedalling. That makes it the clearest full-body option in this comparison.
Standing on a spin bike can increase the stabilisation demand and change how force is produced, but it does not turn the bike into a complete strength program. Regular resistance training still matters.
Which exercise bike is best for your goal?
Best for indoor cycling classes
Choose a spin bike. The riding position, quick resistance changes and ability to move between seated and standing efforts match the way most classes are coached.
The Bodyworx ASB600 is a strong all-round home option with belt drive, Bluetooth and a 150kg maximum user weight. The Pure Design SB8 is the better starting point when magnetic resistance and lower mechanical noise matter most.
Best for a beginner
Either a spin bike or upright bike can work.
Choose an upright bike if you want a larger saddle, a familiar screen and preset programs. Choose a spin bike if classes are what make you excited to train and you are comfortable learning the setup.
For a value-focused spin-bike start, compare the York Performance Speed Bike and Pure Design SB4 V2. For an upright format, the Bodyworx ABX450BT is a useful programmable option with room to progress.
Best for road cyclists
A spin bike or indoor cycle is normally the closest category, particularly when it provides four-way adjustment, cadence or watt feedback and compatible clip-in pedals.
The Sole SB700 offers SPD and toe-clip pedal options and extensive adjustment. The magnetic Sole SB900 is the quieter premium alternative. The Spirit SB850 adds FTMS and watt feedback for riders who value connected data.
An indoor cycle will not perfectly reproduce the geometry, inertia or power accuracy of every outdoor bike. A smart trainer using your own bicycle may be more specific for race preparation, but a spin bike is easier to share and does not require mounting and removing a road bike.
Best for an apartment or shared home
Look for magnetic resistance and a belt drive. These remove friction-pad contact and generally require less drive maintenance than chain systems.
The Pure Design SB8 is a practical magnetic home option. An upright magnetic bike can also be quiet. Use an equipment mat, keep the frame level and consider where the bike sits relative to bedrooms and shared walls.
Best for comfort and back support
A recumbent bike is the obvious category to compare because it provides a backrest and places the rider in a supported position. The Bodyworx Deluxe Programmable Recumbent Bike and Horizon 5.0R are current Fitbiz examples.
Comfort is individual. A backrest does not guarantee that every medical or musculoskeletal issue will tolerate cycling, so seek tailored advice when symptoms are involved.
Best for structured console programs
Choose a programmable upright or recumbent bike. These categories commonly offer numbered resistance, preset profiles, user programs and heart-rate or watt modes.
The Bodyworx ABX450BT is a clear upright example. The Horizon 5.0U and Sole B94 are also worth comparing at higher levels of the upright range.
Best for short, hard full-body intervals
Choose an air bike. Resistance rises automatically with effort, and moving handles bring the upper body into the session.
This is useful for simple training prescriptions such as 10 seconds hard and 50 seconds easy, calorie targets or repeated work-to-rest rounds. It is less attractive when low noise or long cycling-specific sessions are the priority.
Best for several people sharing one bike
There is no automatic winner. Prioritise:
A maximum user-weight rating with sensible headroom.
Adjustment that suits the shortest and tallest riders.
Clearly marked seat and handlebar positions.
Controls every user can understand.
A frame rated for the frequency of use.
Pedals that suit everyone using the machine.
A four-way adjustable spin bike such as the Bodyworx AIC850BT, Sole SB700, Sole SB900 or Spirit SB850 can suit cycling-focused households. A programmable upright bike may be easier when users have different workout preferences and want individual profiles.
A practical buying checklist
Before choosing any stationary bike, answer these questions.
How do you want to ride? Classes and standing climbs point towards a spin bike. Console-led seated cardio points towards an upright bike. Support and access point towards a recumbent. Full-body HIIT points towards an air bike.
Who will use it? Record each rider's height and approximate weight. Compare the adjustment range and leave headroom below the maximum user-weight rating.
How often will it be used? Occasional home use and daily multi-user training place very different demands on a frame, drive system, pedals and bearings.
How important is noise? Magnetic resistance and belt drive are normally the quietest combination. Air bikes are deliberately noisy under effort.
Do you want the bike or an app to control resistance? Many spin bikes use manual control even when they transmit data by Bluetooth. Programmable upright bikes can change resistance automatically.
Which metrics matter? Time and distance may be enough for general fitness. Indoor cyclists may want cadence. Performance-focused riders may want watts, heart rate or FTMS connectivity.
What pedals do you need? Ordinary athletic shoes work with strapped platform pedals. SPD cleats need compatible shoes and pedals.
Will the bike fit the room? Measure the operating footprint, mounting space, ceiling clearance, doors, stairs and delivery route.
How will it be serviced? Check warranty terms, parts availability and maintenance requirements for belts, chains, friction pads and electronic components.
Can you try it? If fit or comfort is uncertain, contact Fitbiz to confirm which models are available to inspect before travelling.
Common mistakes when comparing exercise bikes
Treating “stationary bike” as one design
It is an umbrella term. Always identify whether the product is a spin, upright, recumbent or air bike before comparing features.
Assuming a spin bike is automatically harder
Workout difficulty comes from resistance, cadence, duration and effort. A programmable upright or recumbent bike can be very demanding. A spin bike simply makes certain types of hard training more natural.
Choosing by flywheel weight alone
A heavier flywheel can support smooth momentum, but frame stability, bearings, weight distribution, resistance design and fit all matter. The largest number does not automatically identify the best bike.
Assuming Bluetooth means automatic resistance
Bluetooth may transmit cadence, speed, heart rate, watts or other data. It does not necessarily allow an app to control the resistance. Confirm the protocol, supported metrics and functions.
Ignoring fit because the bike is “adjustable”
Adjustment can mean seat height only, or it can mean the seat and handlebars move vertically and horizontally. The second is much more useful when riders vary in height or want a precise cycling position.
Buying for a fantasy routine
Choose for the workouts you will repeat, not the dramatic workout you might do once after assembling the bike. Consistency tends to prefer equipment that fits, feels stable and is convenient to use.
Frequently asked questions
Is a spin bike the same as an exercise bike?
A spin bike is one type of exercise bike. “Exercise bike” is a broad term that can include spin, upright, recumbent and air bikes. Spin bikes have a more cycling-focused position, substantial flywheel and quick resistance control for classes, intervals and seated or standing riding.
Is a spin bike the same as a stationary bike?
A spin bike is a stationary bike, but not every stationary bike is a spin bike. Stationary bike is the umbrella term for indoor bikes that stay in place.
What is the difference between a spin bike and an upright bike?
A spin bike usually places the rider farther forward and supports standing efforts, quick manual resistance changes and indoor cycling classes. An upright bike keeps the torso more vertical, uses a larger saddle and often provides electronic resistance levels and preset programs.
Which is better: a spin bike or exercise bike?
Choose a spin bike for cycling-style workouts, classes, cadence intervals and standing efforts. Choose an upright exercise bike for seated comfort, programmed resistance and straightforward console-led cardio. “Better” depends on the rider and intended use.
Is a spin bike better for weight loss?
Not automatically. Weight loss depends on total activity, nutrition and consistency. A spin bike can support high-intensity and longer aerobic sessions, but an upright or recumbent bike may be better if it allows you to train more consistently.
Is a spin bike harder on the knees than an exercise bike?
Not necessarily. Resistance, cadence, saddle position, training volume and individual health all influence knee comfort. Very low resistance at an uncontrolled cadence can be as unhelpful as excessive resistance. Set the bike correctly, progress gradually and seek professional advice for persistent pain or a known condition.
Can beginners use a spin bike?
Yes. Start seated, use manageable resistance and keep the first sessions short. Learn to adjust the saddle and handlebars before adding standing climbs or sprints. A beginner who enjoys classes may be more consistent on a spin bike than on a machine they find less engaging.
Can you stand on a normal exercise bike?
Do not assume so. Spin bikes are generally designed for standing efforts, while conventional upright and recumbent bikes are primarily designed for seated use. Follow the manual for the specific model.
Are spin bikes noisier than upright exercise bikes?
It depends on the resistance and drive system. A magnetic belt-drive spin bike can be very quiet. Friction-pad and chain-driven bikes may produce more mechanical sound. Upright magnetic bikes are also usually quiet. Air bikes are the loudest category at high effort because of the fan.
Do spin bikes have automatic resistance?
Many do not. A typical spin bike uses a manual knob, even when Bluetooth transmits workout data. Some premium connected bikes offer electronic control, but this should be confirmed rather than assumed.
Is a recumbent bike easier than a spin bike?
A recumbent bike is often easier to mount and provides back support, but the workout can still be challenging when resistance and duration are increased. It is better described as a different position, not an inherently ineffective one.
Is an air bike a stationary bike?
Yes. An air bike is a stationary exercise bike that uses a fan for resistance. Most models also have moving handles, creating a full-body workout that differs substantially from a spin or upright bike.
Which stationary bike is best for home use?
For classes and cycling-style training, choose a spin bike such as the Bodyworx ASB600, Pure Design SB8 or Bodyworx AIC850BT. For comfortable programmed cardio, compare upright models such as the Bodyworx ABX450BT. For back support and easy access, compare recumbent bikes. For short full-body intervals, compare air bikes.
Does Fitbiz deliver exercise bikes across Australia?
Fitbiz ships within Australia. Freight for heavy, bulky, regional or remote deliveries may require a custom quote or tail-lift service. Check the product page and contact Fitbiz if stairs, narrow access or a difficult delivery route are involved.
Final recommendation
Do not let the terminology make the decision harder than it needs to be.
Start with the workout:
Choose a spin bike for indoor cycling classes, cadence work, standing climbs and a more bicycle-like position.
Choose an upright exercise bike for comfortable seated cardio, automatic resistance and built-in programs.
Choose a recumbent bike when a supportive seat, backrest and easy access are priorities.
Choose an air bike for short, hard, full-body conditioning.
For most home buyers specifically looking for a spin bike, the Bodyworx ASB600 is a strong all-round starting point. The Pure Design SB8 is the more appealing choice when magnetic resistance and home-friendly noise matter most. The Bodyworx AIC850BT is the step up for four-way adjustment, cadence feedback and FTMS connectivity. Committed cyclists should compare the Sole SB700 and Sole SB900, while high-frequency and multi-user training can justify the commercial Spirit SB850.
If you are still unsure, send Fitbiz the heights and approximate weights of the riders, how often the bike will be used, the workouts you enjoy, whether noise matters and which apps or cycling shoes you already own. Those details are far more useful than asking whether a spin bike or exercise bike is “better” in the abstract.
You can compare Fitbiz spin bikes and indoor cycles, upright exercise bikes, recumbent bikes and air bikes online.
