"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.

Drivetrain Options - What Drives You?
You've decided which Co-Motion is right for your kind of riding. Did you know we're also the leader in tandem drivetrain options? These are the available drivetrain options for the Supremo.

  • SRAM Force eTap AXS 1x12 speed kit
  • SRAM wireless eTap shifters and derailleurs are a game changer. They're quiet, smooth and efficient providing faster shifts with no wires

  • Gear Inches- The descriptions above refer to gear inches for comparison purposes. The term refers to the effective equivalent wheel diameter per pedal stroke. For example, if you're pedaling the Supremo with SRAM AXS in first gear, each full pedal stroke will produce the equivalent of one wheel revolution of a 23.2" wheel, while the highest gear will produce the equivalent rotation of a 116.1" wheel.
