Two types of exercise bikes are available. The design of the upright bike resembles that of a typical road bike but they are stationary. The pedals are positioned below the rider and puts added stress on the joints. The seat on the recumbent bike's seat resembles chairs and the pedals are out in front of the rider so that pedaling is more natural and puts less stress on the joints.

Other types of exercise bikes are available as well. Dual action exercise bikes are upright bikes that have moveable bars or arm handles. You use both of your arms and your legs on this bike. While using this bike you will experience aerobic activity and upper body toning.

There is variety with resistance bikes as well. With direct tension bikes you can manually adjust the resistance you use. The cycling motion on a bike with flywheels is like regular cycling motion. Bikes with air assistance get resistance by pedaling against the airflow of a fan blade.

The most sophisticated resistance bikes are magnetic frictionless resistance bikes. These bikes provide greater variety of workout levels. On more advanced bikes there are feedback mechanisms that show the following readouts: speed, time, distance , total calories and fat burned, program mode, resistance levels, pulse, heart rate, and work out levels (RPM, watts, METS, mpm's, and mph/kph).

The bike you choose to purchase will depend on your wants and needs. The type of workout you're looking for will also influence your choice of bikes. A great cardio workout focused on the quadriceps is provided by an upright bike. You are seated in a reclining position on a recumbent bike.

Your back is supported by the seat and your legs are out in front of you. The hamstring muscles and the gluteus muscles get worked. Your lower back is less stressed on a recumbent bike. Some upright exercise bikes will have handlebars that move in a simulated rowing motion.

Your back and chest and your arm and back muscles will get a workout. You will get an excellent cardiovascular workout and calorie burning experience with both of these bikes. The bike should be matched to your size. Exercise bikes for the most part are easily adjusted for almost any body type.

There is a variety of reasons why people use exercise bikes. Cyclists use them to keep up their level of fitness in the off season. Many people feel embarrassed about exercising in front of people so they use them at home. Physical therapy programs also use exercise bikes in their programs to promote healing and the regaining the use of knee and hip joints.

Some cardiac rehab programs use them as well, to promote endurance and greater cardiac health. Exercise bikes can be purchased in sports stores, department stores like Wal-mart or Sears, as well as online. Buying them from a store makes it easier to match the bike to your space, to your body size, and your budget.

Buying online creates the risk of you not getting exactly what you ordered. The bike you ordered may not have the exact specs or may be bigger or smaller than what you ordered. Taking delivery is another problem with ordering online. It is very likely that the delivery company will not bring it into your house, you will have to bring it in and set it up.

Even though you are buying it in a store this is true, unless you contract with someone to do the entire process including setting it up. You can purchase service contracts from a store like Sears, in case of a problem. No matter what the reason you have for purchasing an exercise bike, it will only work if you use it.

You should check with your doctor to make sure you are healthy before starting a new exercise routine. At first you should start out slow and build up endurance. Your endurance will improve if you start out slow.

Have fun, be safe and be healthy.
