My understanding is that the Flex can do a bit more in the way of correction and that it is easier to use for longer periods than the Cyclo. With that said, the only one of the machines I have experience with is the Cyclo. I felt that it was well balanced. The main drawback I had with it was that was single speed (and it was bulky at times).
