Spinning® Bike Advice, Indoor Cycle Reviews and Benefits

Introducing Spin® Bikes

You’ll often see these types of bikes at the gym or in cycle studios. They are used for high intensity cardio training.
Though a lot of people think of “spinning” as a generic word for exercising on an indoor cycle, it’s important to note that the words SPIN®, Spinner®, and Spinning® are terms that are copyrighted by a company called Mad Dogg Athletics. Only their bikes can be called Spinning® Bikes. The generic name for this type of bike is indoor cycling bikes. But most people call them spin® bikes.

Strengthen and Tone

Cycling will strengthen and tone your leg muscles. The primary muscles worked on a bike are the quadriceps (front of the thighs), glutes (bottom), hamstrings (back of the thighs), calves (back of the leg below then knee) and hip flexors (bottom of the stomach).

Weight Loss

Spin® class training is a very effective form of exercise for weight loss. The number of calories burned will depend on your age, gender and so on but as a guide a young man can burn around 500 calories cycling for 30 minutes at around 17mph. Once you’ve finished your cycle your body continues working to repair the muscles used during your workout. This burns calories even once you’ve finished exercising.

Cardiovascular Fitness

Indoor Cycling is an effective and simple form of cardiovascular exercise. Cardio training on an exercise bike can help you prepare for marathons or just help you deal better with daily demands. A healthy cardiovascular system increases the supply of oxygen to your blood and the supply of energy to your body. It helps reduce your risk of stroke and disease and can lower blood pressure.

Improve Your Sport

An indoor training bike can be more than a piece of home gym equipment. It can allow for specific training focused towards the discipline of road cycling. The controlled environment that an exercise bike produces can help improve and track your cycling fitness as well as improve your technique. Exercise bikes let you work on the elements you need to improve on, whatever the weather!

Low Impact Exercise

The low impact nature of indoor bikes make them a good option if you want to lessen any risk of injury or strain. Their smooth motion and low impact action combine to make a workout that is easy on your muscles and joints. As long as your bike is properly configured and set up in line with your biomechanics the pressure is taken off of knees and ankles making indoor cycling a popular alternative to higher impact activities such as running.

Convenient and Cost Effective

Our bikes are compact and sleek machines that don’t take up much space. They also let you make maximum use of your time: you can watch TV, read a book or listen to music as you workout. Cheaper than paying gym fees, all of our bikes come with fantastic warranties that ensure you get years of exercise out of them.

Buying an Indoor Cycling Bike For Home?

If you’ve taken part in a Spinning® class or used a Spin® bike at your gym you’ll be aware of the type of high intensity workout you can achieve. Working out in a group can help improve motivation. However having an indoor bike at home will mean you can benefit from the convenience of exercising regularly without the time constraints of going to the gym or waiting for your next class.

Exercise Bike Flywheel Size

The flywheel size of a bike is important as it will determine the bike’s maximum resistance. An enjoyably smooth and silent ride is also only possible with a large flywheel, if the flywheel is too small the ride will be more jerky.

Adjustable Seating Position

To enjoy cycling as a low impact, long term form of exercise it is vitally important the bike is set up perfectly in line with your biomechanics. As such a fully adjustable bike is highly recommended.


The key considerations with a cycling computer are accuracy and options. You will want confidence in your data and it is worth checking what is tracked as the number of metrics recorded do vary. Programs are a great way to vary your workouts and stay motivated.

Build Quality

This is clearly vitally important but notoriously difficult to decipher online. It is worth checking out the total product weight here as lower quality, less stable bikes will tend to weigh less.


Often warranties are from the original manufacturer rather than the company you bought the machine from. Make sure the warranty covers in-home repairs or the delivery and collection costs for your machine. Otherwise you may find bike repairs which cost as much as the original purchase.

Choosing Where You Put Your Exercise Bike

We recommend that you don’t keep electric fitness equipment in cold rooms or garages. In the winter months, the temperature fluctuates which causes condensation inside the computer and circuit board.

Check Customer Reviews

Reviews are a great way to understand if a company is as good as they say they are. We collate our reviews in association with TrustPilot, which means you can be absolutely sure they are independent, authentic reviews from genuine customers.

Money Back Guarantees

If you are buying fitness equipment over the internet make sure you have the right to change your mind once you have assembled the machine and tried it out. Most reputable companies have a 28 day money back guarantee as long as you return it in the original packaging and pay for delivery costs. See our ‘no quibbles’ returns policy.

After The Warranty Period

If the machine has a short warranty period it’s worth enquiring how much it will cost to fix the machine and the cost of parts.

I had been researching spin® bikes for some time, and ended up on the Cyclo 6. Thankfully that research paid off, as the bike is fantastic. The construction itself is great, it feels very sturdy, feels great to ride - and looks the part too! On other points, which I think pretty much confirmed my sale was team at JTX fitness, who were nothing short of excellent. Customer service is something that's being lost in today's online age, but the guys were brilliant from my initial call through to delivery. All of my questions were answered quickly and easily, and with minimal fuss - in short, a master class in service which is worth it's weight in gold. But, back to the bike - It's been fantastic, really good quality and is getting a lot of use. So my gluteus maximus are in pain, which means my face is smiling. Thanks again to JTX Fitness for a top product. I can certainly recommend!

Jody Minton (TrustPilot Reviewer)

After the ancient road bike I used on a turbo-trainer finally gave up the ghost, I decided to go for an exercise bike which my wife could use as well, and which could deal with a lot of punishment. I saw how good the reviews for the JTX Cyclo 6 were, and decided to go for that model. It is an extremely well-made piece of kit, very heavy, which is essential for spinning® workouts, but also surprisingly quiet. It was straightforward to set up, with two of us being needed to carry the frame and wheel up to our attic even after unpacking it into component parts. I have no complaints about the weight of it though, because it gives an extremely secure base for vigorous spinning® training. A superb piece of kit, and very good value for money.

I ordered my exercise bike on aTuesday afternoon, and it came, as promised on Thursday. We tried to assemble it on Saturday, but a part was broken. I contacted JTX on Monday, and on Tuesday morning, the replacement part arrived. Customer service was excellent, and very friendly. The bike, now it is fully assembled is great. Lots of different programs I can use, as my fitness levels improve, and it is very comfortable to use - no need for a replacement gel seat! A great company, and I would certainly recommend it to anyone considering purchasing decent quality exercise equipment.
