Exercise Bike Buying Guide - How to Choose the Best Exercise Bike for Your Fitness Goals
Buying an exercise bike should feel straightforward - but once you start looking at the different types available and the range of features on offer, it can quickly become overwhelming.
This guide focuses on what really matters, helping you choose an exercise bike that suits your goals, your space and your budget - without paying for unnecessary extras or cutting back on features that genuinely make a difference.
Before You Buy - Start With Your Goals
Before comparing specifications, take a moment to think about how you will use the bike.
How will you use it?
- How often will you train - occasional sessions or daily use?
- What type of workouts will you do - light cardio, longer endurance rides, or high-intensity sessions?
The more frequently and intensely you plan to train, the more important frame strength, resistance quality and overall durability become.
You will also find that some bike types are better suited to certain workout styles - we will cover that later.
Who will use it?
- Just you, or multiple household members?
- Is there a significant height or weight difference between users?
- Does maximum user weight rating comfortably support the heaviest user?
- A higher maximum user weight also usually indicates a stronger, more stable frame - even if you are well below the limit yourself.
- Seat and handlebar positioning - seat height range, forward/back seat adjustment, handlebar adjustment
Where will it go?
- Will you be using it in a shared living space?
- Consider noise levels.
- Magnetic resistance bikes are typically very quiet, while air bikes are noticeably louder.
- If the bike needs to be moved between sessions, look for transport wheels and check the overall machine weight - especially if stairs are involved.
Types of Exercise Bikes - Which One Suits You?
Understanding the main types of exercise bikes will help you narrow your options before comparing detailed specifications. Each type suits a different training style and level of intensity.
Spin Bikes
Also referred to as studio bikes or racer bikes, spin bikes are designed to feel closer to outdoor road cycling. With a slightly forward-leaning position and the ability to stand while pedalling, they are well suited to interval training and harder efforts.
Best bike if you want:
- HIIT or interval-based workouts - the forward riding position supports higher intensity efforts
- A more performance-focused ride - designed for harder, more dynamic sessions
- Structured cycling sessions - ideal for app-based or coached workouts. Check for app connectivity.
- A bike that feels closer to outdoor riding - similar posture and pedalling mechanics
- Higher calorie burn sessions - intensity is easier to maintain
Not ideal if:
You prefer a more upright, relaxed riding position rather than a performance-focused setup.
Upright Exercise Bikes
For a more relaxed and accessible riding experience, upright bikes position you in a vertical seated posture with handlebars set higher and less forward lean than spin bikes. This makes them comfortable and easy to use for most home users.
Best bike if you want:
- Regular cardio workouts you can sustain long term
- Weight loss training through consistent, manageable calorie burn
- A comfortable, joint-friendly ride that is easy to stick with
- Easy access on and off the bike
- A compact, space-efficient machine for home use
Not ideal if:
You want high-intensity standing intervals or a ride that closely mimics outdoor cycling.
Air Bikes
Using a large fan-wheel to generate resistance, air bikes respond directly to how hard you pedal. They feature moving handlebars which engage both upper and lower body at the same time.
This design allows the bike to scale from gentle recovery work to intense conditioning sessions.
Best bike if you want:
- A full-body workout using both arms and legs
- High calorie burn - resistance increases automatically as you push harder
- Functional or cross-training sessions
- Intense intervals or steady endurance rides - resistance scales with effort
- A bike suitable for recovery work, as you control intensity naturally
Not ideal if:
You need a very quiet bike for a shared living space, as the fan system produces noticeable noise.
Erg Style Bikes
This type of bike can technically fall under air bikes, but the design differs from those previously discussed. For example, no moving handles. It may also be referred to as a fan bike or BikeErg, although the latter is a trademarked name used by a specific manufacturer.
Using a fan wheel, resistance increases as you pedal harder, so intensity adjusts naturally without fixed levels. A clutch-style flywheel allows the wheel to keep spinning when you stop pedalling, creating a more road-like feel when coasting.
Best bike if you want:
- A bike suited to both steady endurance rides and short power intervals
- Performance-focused training based on measurable output
- Resistance that responds directly to cadence and power
- Detailed metrics such as watts, pace, distance, calories and frag factor
- Repeatable, data-driven workouts
Not ideal if:
You need very quiet resistance, as air-driven systems are louder than magnetic bikes.
Recumbent Exercise Bikes
Designed with comfort and support in mind, recumbent bikes place you in a reclined position with a larger seat and supportive backrest. This reduces pressure on the lower back and joints.
The seated position makes them especially suitable for longer steady sessions or rehabilitation-focused training.
Best bike if you want:
- Maximum seated comfort and back support
- Reduced strain on knees, hips and lower back
- Easy access with a stable step-through design
- Longer steady workouts in a supported position
- A lower-impact option for recovery or rehabilitation
Not ideal if:
You want higher-intensity training or out-of-saddle riding.
Key Features to Consider
Particularly for spin bikes the market is flooded with many options. Here are some of the main features to look out for:
Resistance – Spin Bikes
Magnetic resistance has become standard on many modern spin bikes, gradually replacing friction resistance which you might still find on budget models.
Benefits of magnetic resistance:
- Very quiet and suitable for shared environments
- Smooth, controlled resistance changes
- Low maintenance due to minimal friction
Flywheel Weight (Upright & Spin Bikes)
The flywheel influences how smooth and stable the pedalling motion feels.
A heavier flywheel can create a more stable, consistent pedalling motion — particularly during faster cadence or standing efforts.
Note: Flywheel weight affects ride smoothness, not maximum resistance.
Resistance is created by the resistance mechanism (e.g. magnetic or air) and how it is engineered. A heavier flywheel does not automatically mean the bike offers greater difficulty.
When comparing bikes, ensure you are assessing overall build quality and resistance range - not just flywheel weight.
Comfort & Adjustability
Achieving the correct riding position will make workouts feel more stable and reduce discomfort during longer sessions.
Check:
- Bike dimensions when assembled – make sure it doesn’t feel too small for your body size
- Max and min seat height
- Seat adjustment (forward and back)
- Handlebar adjustment
- Pedal options (standard straps or SPD compatibility)
Frame Strength & Maximum User Weight
A higher max user limits usually reflect:
- Stronger frame construction
- Greater stability during harder efforts
- Improved long-term durability
Console & Connectivity Features
App Compatibility
If you plan to use interactive training apps such as Zwift or Kinomap, consider the following:
- Does the bike have wireless connectivity. Is it compatible with your chosen app?
- Is the bike fully functional on its own, or does it rely heavily on app integration?
- If a trial subscription is included, does it auto-renew and how much will it cost afterwards?
Built-In Programmes
Most exercise bikes include:
- Manual mode
- Pre-set training programmes
- Interval workouts
- Heart rate-based sessions
If structured training is important, ensure the console offers enough built-in variety without relying entirely on an app subscription.
Heart Rate Monitoring & Training
Options may include:
- Hand pulse sensors for general guidance
- Bluetooth chest strap compatibility for more accurate tracking
For structured or zone-based training, wearable compatibility is preferable.
5. Space & Setup Considerations
Size & Footprint
- Measure your available floor space and check the bike’s assembled dimensions
- Allow adequate clearance on each side of the bike for access
Moving & Storage
- Most exercise bikes include transport wheels for repositioning.
- You can also get folding designs – but these tend more common on cheaper models few models fold, their compact footprint usually makes folding unnecessary.
Environment
- Avoid damp, very cold or unheated spaces where electronics and moving parts may deteriorate.
- A dry, stable indoor environment improves longevity.
Warranty & Support Features
A strong warranty provides reassurance and reflects manufacturer confidence.
- Most warranties cover home use only
- If you’re planning to use the machine in a commercial setting, it’s important to check that a commercial warranty is included.
- Typical coverage includes:
- Parts & labour: 1–3 years
- Frame: long-term or lifetime cover
Final Buying Tips
- Match the specification to how often and how intensely you will train
- Prioritise comfort and adjustability over headline numbers
- Don’t focus solely on flywheel weight
