If you are not really interested in health and fitness, then you may well assume that indoor cycling bikes and upright exercise bikes are the same thing, but that's not actually true.
Although they are both designed to help you improve your fitness, tone up your body and burn fat, they are two completely different machines.
Upright exercise bikes have been around for a very long time, and are one of the most popular exercise machines that you can buy for your home, but an indoor cycling bike is more like a racing bike because the handlebars are lower and it is easier to pedal in a standing position on one of these bicycles.
As a result of this, they are ideal if you are a keen cyclist who wants to get a good workout when the weather is bad outside.
They are also useful if you want to get a fat-burning interval training workout at home without having to fork out for regular spinning classes at your local gym. You just need to find some YouTube videos or buy a workout DVD, and then you can perform one of these workouts in your living room, bedroom or garage, for example.
You can take a look at some of the bikes that are available by checking out this page, which lists the best indoor cycling bikes based on factors such as build quality, the range of resistance that is available and the smoothness and noise level of the actual workout.
If you want to buy one that is just as good as some of the gym bikes, then you can expect to pay nearly $2000 for a Keiser M3 Plus or a Schwinn AC Performance Plus Bike, for example, but you don't necessarily have to pay this much if you don't want to.
There are several bikes in the $500 - $1000 price range that are nearly as good as some of the top-end models, and even some of the cheaper bikes are really well-made and capable of providing a comfortable and very quiet workout, such as the Sunny Health and Fitness Pro Indoor Cycling Bike, for example.
Therefore you basically need to decide whether you will actually benefit from this type of exercise bike first of all, and then think about how much you want to pay for one of these impressive-looking bikes if you decide to buy one because they can vary in price quite considerably.
