Brief Guide to Indoor Cycle Spin Bike

What Are They?

Indoor cycle spin bikes are stationary exercise bicycles that are especially made for spinning. Spinning bikes are made more like racing bikes so that you lean forward or stand up rather than sit upright when you use them. They are designed to simulate a hill, and work you hard at a fast pace.

The machine usually has a weighted flywheel linked to the pedals which results in a bike with fixed gears. This means you can’t just stop pedaling, but have to gradually stop, so you are getting exercise even when you are slowing down to a stop. Just like using an outdoor bicycle, you can also stand up on the pedals in order to go up hills or go faster.

Often gyms will have spin classes where a whole class gets together on spin bikes and the leader calls out when to slow down and when to speed up. Some people might like to practice and train at home, so they can do that with this bike.

They are usually more mechanical than standard exercise bikes, and simpler to operate and use as they don’t usually have a control panel. This also means they are less likely to go wrong. They are usually adjustable too, like an outdoor bike, so the seat can be lowered or made higher, as can the handlebars.

Who Can Benefit?

These bikes are a great buy if you are looking to outfit your gym or fitness facility. You can get several and either use them for a spin class, or just for people to use who are going there to train.

Cyclists can use this type of bike to train when the weather is wet, or too hot or cold to exercise outside, as they are designed to simulate outdoor cycling and will give you a great workout. It is also great for when the daylight hours get fewer, so you don’t have to worry about lights, or cars not seeing you in the dark, and can just exercise at home instead.

If you like cycling when you are at the gym this will save you a lot of money on gym membership in the long run, as you can do the same exercise at home. It will also be more convenient for you, as you won’t have to get dressed to go to the gym or worry about how busy it is there – instead you can just exercise whenever you feel like it, and however you’re dressed.

Spinning is also a great exercise for people who have injuries or chronic health issues, as it doesn’t put pressure on as many joints as some other forms of cardio exercises do. For example if you have knee problems, running will put more stress on your knees – but spinning shouldn’t hurt your knees like running would.

You might also want to consider a purchase like this if you are accustomed to going to the gym regularly but have a separate summer home where you don’t have gym membership. Then you can easily continue your training during your vacation time.

What To Look For?

Primarily you want to look for a good quality and heavier fly wheel as it will add more intensity to your workouts. 40lbs or more is a good place to start. Also look at the weight that the bike will handle – some are designed for lighter weight athletes, and it is a good idea to get one that is OK for a little over your weight.

If you prefer to have a computer linked to your bike and see how many miles you’ve cycled, you can also purchase bike computers that will connect to it. Some models will also have display screens, though many don’t. If you do get one with a display screen, you can often get information such as your heart rate, calories burned, distance covered, and time cycling.

There are two types of resistance that a spin bike works with. Magnetic resistance means that the closer the magnet moves to the flywheel, the harder your workout will be. Bikes that offer magnetic resistance often have several different terrain types and usually last longer since there is no friction involved.

The other type of resistance uses a chain and belt. These models don’t offer such an intense and challenging workout, but they are often known for their reliability, and are quieter than the magnetic type. They also don’t need much maintenance.

It is also wise to get a bike that offers handlebar adjustment to avoid any back pain you might get. And if you think you might be sitting quite a bit then you might want to get one with a padded seat for comfort, although you can always buy a padded seat cover if it’s not soft enough for you. Also look for a good strong and durable frame.

What To Avoid?

When you’re buying on the internet it can be hard to see what the quality of a bike is like, so make sure you check the reviews and don’t get too cheap of a model.


Is there anything I need to do to maintain a spin bike?

It is recommended that you oil the flywheel periodically so that it keeps moving smoothly.

What kind of exercise does a spin bike give you?

Spinning is good for endurance training, as it builds up your muscular endurance. It is also a great cardiovascular exercise and should increase your lung capacity and heart health as well.

Do you have to assemble the bikes?

There is usually some assembly required, but with good models they should have readable instructions and it shouldn’t need too much assembling.

Can you watch TV while you cycle?

Some bike companies offer a kit to attach an iPad, or you can watch TV in front of you. If you want to watch TV then you might be best getting the chain and belt type of model as they are a lot quieter when they run.

Wrapping Up

Whether you are a beginner or a seasoned hardcore cycling master, there is something on this list for you. From economical to high end, or just the basics, these fantastic spin cycles will get you where you need to go.

Enjoy the health benefits without ever leaving the convenience of your home.
