I rode another recumbent for two years and loved the comfort, but it was hard to keep up on group rides. Switching to the Cruzbike S40 was a game-changer. The learning curve was quick, coming from another recumbent, and the performance boost was immediate, especially climbing. I can now keep up on group rides and have completed numerous century rides, all while staying comfortable and pain-free. If you want recumbent comfort, real speed, and climbing ability, the S40 delivers.
