I have been an early adopter purchasing my first Cruzbike, a Silvio 1.0, in 2009. My main objective was to increase the comfort of riding from a standard road bike. I purchased and rode a variety of recumbent trikes over the years, but missed the speed and adjility of road bike. The Silvio facilitated that goal. There is a learning curve to riding a Cruzbike, but it well worth the effort, not to mention the benefit of strengthening your core and having no tush pain. I currently ride a modified S40 Gen2. It has been a great, reliable ride.
