Indoor cycles, also known as Spin® bikes have become a staple piece of equipment in many home and commercial gyms. Over the last couple of decades, the market has diversified to supply a range of different indoor cycling bikes. In this article, we’re going to help you decide which indoor cycling bike is best for you.
What Is an Indoor Cycle or a Spin Bike?
Indoor cycles, or Spin® bikes, are designed to be a stationary version of a traditional road bike. Both the design and feel of the bike replicates the experience of being on a road bike. Instead of gears, indoor cycles contain a flywheel that mimics the resistance felt on a traditional road bike.
Indoor Cycle vs Upright & Recumbent: What Is the Difference?
Stationary bikes can be further divided into indoor cycles, upright, and recumbent bikes. While they all require a pedaling motion, their appearance and feel differ dramatically. Take a look at the table below to see the key differences between the three.
|Difference||Indoor Cycles||Upright Bikes||Recumbent Bikes|
|Resistance||Heavy flywheel.||Light flywheel.||Light flywheel.|
|Seated Position||Seat is above the handlebars. Rider sits with a forward lean. Pedals are beneath the seat.||Seat is below the handlebars. Rider sits in an upright position. Pedals are beneath the seat.||Seat is below the handlebars. Rider sits with a backward lean. Pedals are in front of the seat.|
|Gadgets||Some models are compatible with apps, but others lack real-time data.||Typically display real-time data.||Typically display real-time data.|

The 3 Most Important Things You Should Know Before Deciding
The differences within indoor cycles are typically characterized by their resistance, flywheel and drive system, and multimedia/connectivity. These differences are likely to be the deciding factor as to which indoor cycle you decide to invest in.
Indoor cycles contain a heavy flywheel used to generate resistance. Resistance is created by magnets, friction, or a combination of both. Magnetic resistance is adjusted by magnets moving closer or further from the flywheel. The closer the magnets get to the flywheel, the greater the resistance. Friction resistance is adjusted by strong cotton felt pads moving closer or further from the flywheel. Magnetic resistance is typically quieter, requires less maintenance, and doesn’t need to be replaced often. But, friction resistance is much more affordable.
Flywheel and Drive System
Indoor cycles contain a flywheel. Their flywheel can be perimeter-weighted or center-weighted. Perimeter-weighted flywheels are typically heavier but have less consistent flywheel weight distribution compared to center-weighted flywheels. Perimeter-weighted flywheels can provide more resistance, but put more stress on the knees.
Indoor cycles can contain a chain or belt drive. Chain drives are typically seen on classic outdoor cycles. They replicate real-life road biking but are subject to more wear and tear. This is due to the connected chain links. Since belt drives don’t have chain links, they’re less susceptible to damage. Belt drives are also typically quieter than chain drives.
Gone are the days when an indoor cycle had just a seat, handlebars, and some pedals. In today’s society technology is everything, even when we exercise. More advanced indoor cycles come with wireless multimedia technology that allows you to track your workouts and compete against others. These features can be a great asset to training and help with your motivation and adherence. However, these extra features also come with a hefty price tag.
So, what is the best spinning bike for home use?

What You Should Consider Before Buying a Bike for Indoor Cycling
Now we’ve looked at our indoor cycle top picks, let’s help you determine which one is best for you. We all have our criteria when it comes to making an investment. Here are the main things you should consider before buying your indoor cycle.
Adjusting the resistance on your indoor cycle allows you to work at different intensity levels. Training at different intensities helps you train towards your individual fitness goal. Playing with the resistance can also aid progression as you get fitter. The Schwinn IC4 indoor cycling bike includes magnetic resistance with 100 micro-adjustable resistance levels. Most bikes do not need this many levels, but the more levels, the more you have to play around with.
Additionally, you’ll have to consider how the bike creates resistance. Resistance is created by magnets, friction, or a combination of both. Magnetic resistance is typically quieter, requires less maintenance, and doesn’t need to be replaced often. But, friction resistance is much more affordable.
Flywheel weight is a popular topic of conversation when it comes to indoor cycles. The greatest question is whether a heavier or lighter flywheel is better? The answer depends on what you’re looking for. Heavier flywheels make pedaling controlled and less jerky. They produce more power at a steady rate, thus placing less pressure on the joints. But, heavier flywheels do require more energy to get moving and typically cost more. Conversely, lighter flywheels need less effort to get moving and are typically more cost-friendly. However, its light weight makes the movement less smooth and thus can aggravate the joints. Most indoor cycles are designed to suit heavy flywheels. But, advancements in engineering have shown indoor cycles can provide a smooth, stress-free ride with a light flywheel. Indoor cycles such as the Keiser M3i Indoor Cycle have proven this with their impressively designed bike.
Most indoor cycles operate with a chain or belt drive. Chain drives mimic that of a real-life road bike. Many road cyclists prefer this feel as it crosses over into their primary sport. But, chain drives are more susceptible to wear and tear due to their connected chain links. Therefore, chain-drive bikes often require more maintenance. Belt drives don’t have chain links, therefore, are less likely to need regular maintenance. Belt drives are often quieter than chain drives, perfect if noise is a concern.
Q-factor is defined as the distance between the pedal attachment points of each crank. Essentially, it measures your stance width when standing up. A narrower Q-factor allows for greater speed because less force is needed to rotate the cranks. Additionally, Q-factor is used for people with knee injuries and rehabilitation. Q-factors that are too wide or too narrow may cause additional knee problems.
Inseam refers to your individual leg length. Finding the optimal inseam can make your ride safer and more comfortable. Just like your clothes measurement, inseam is the distance between the highest point of your inner thigh and the heel of your foot. You’ll need your bike to accommodate your inseam measurement to provide maximal safety and efficiency. Most bikes accommodate the majority of the population. But, if you’re particularly small or tall, you may want to double-check before investing. The Keiser M3i Indoor Cycle accommodates riders from 4’10” – 7’ tall.
Many indoor cycles are compatible with specific cycling or workouts apps. If you want to get data specific with your cycling or follow non-cycling-specific workouts, connectivity is a must. While they’re great features, they often come at a cost. If data isn’t your thing and you just want something to get you moving a bit more, basic, cheaper models are generally just as good.
Indoor cycles are designed to mimic traditional road bikes. They provide real-life cycling feel from the comfort of your own home. Whether it’s time or convenience, we don’t always want to take the bike outside. This is where indoor cycles ride in. While everyone has different needs, you can be sure there’s an indoor cycle for you.
