Due to Neck, back issues needed something better than a standard bike. First got the S40 and found it comfortable and capable. Wanted to go further faster and added the V20c. I use the S40 for general riding, used it at ride across Georgia, ride across Iowa and when I am riding with a 17-18 mph group. Will use it to ride Pittsburgh to DC this year and BRNW V20 used it for centuries I want to push, fast group rides. Both are great. Everyone is different but once you relax it makes transition to recumbent easier. I also spend time in Winona lake, Indiana during summer months so available there as well. Best decision to use Cruzbike ever.
