Anyone who is thinking of buying an indoor exercise bike has two basic choices. They can choose a recumbent bike or an upright bike.

Recumbent bikes differ from uprights in that they allow the user to pedal while in a reclining position. This helps save a person's back from strain. Uprights are popular for different reasons such as their ability to offer plenty of exercise while allowing the user to pedal standing up. Also, they offer more convenience as pedaling is done right underneath the body.

A lot of users love uprights because they are capable of letting them get as much exercise as they want while bike riding, no matter what the weather is like outdoors. These can offer the same programmability as recumbent bikes, but they are also great for adding variety to a workout.

For added impact, a user can stand up and pedal on an upright. This flexibility alone makes it popular. Also, because the pedals are positioned just beneath the user's body, it can make it easier to remain on the bike for longer periods because there is less discomfort. This is what make makes these bikes extremely popular.
