"The Co-Motion Supremo is our second tandem since 2001, and by far the lightest and best riding we've owned." C. More
" It has been a long time since we had such a high average speed. There were a few stretches where we were riding 21-22 mph, and actually felt a few times like we were "running out of gears. It was REALLY fast." Greg R.
