RE: I love to ride my Bi-cy-cle, but which type's best
Recumbant (or bent) is the laid down bike.
There are a lot of bent cyclers that will tell you that there's no difference other than your ass isn't sore after a long ride.
I disagree...I find that the intensity of a standard upright is much higher. Also, if you want to do HIIT training on a bike, upright is the way to go because you can stand for some of your intervals, increasing intensity further because you've added your body weight as resistance.
Bent bikes are ususally pretty expensive too.
