There are a lot of good places on the net to visit for exercise bike reviews. You can find essentially two types of reviews. Reviews by manufacturers may be a little biased because they might want you to buy their bike so they talk all about the super-features but leave out the bad things. Then there are the consumer opinions and reviews from different types of bikes. These reviews might prove to be more valuable because they come from real flesh people who have gone through the ownership of equipping themselves with the exercise bike you wish to posses. These sorts of reviews are usually much more objective than a bike's manufacturer review because these bikers list both the pros and cons of their equipment.
