The Horizon RC-30 is one of two standard exercise bikes (RC-30, RC-40) featuring a low, recumbent-style frame designed for comfort. Though it lacks the iPod dock on the Horizon Bxxx models (B600, B701), the RC-30 has better exercise-related features such as handle-mounted pulse grips for monitoring heart rate; 8 built-in workouts including interval, rolling hills, weight loss, and even tempo-based routines; and 8 programmable resistance options.
