The recumbent riding position results in a smaller frontal area compared to upright bikes and higher speeds are often obtained, especially down hills! When it comes to climbing, most riders find themselves going a little slower due to several factors: No leg or body weight over the pedals, and carrying a little more bike weight compared to uprights of similar quality. Overall, the downhill speed generally makes up for a little time lost on the upgrades. The current hour record for a time trial bike is about 35 miles while a streamlined recumbent has done over 47. The best speed achieved by a recumbent on level ground is 82.33 mph.
