How to Measure Your X-Seam

At Electric Trike Store, we like to use the X-Seam measurement to fit riders on recumbent trikes, and inseam to fit riders on upright trikes (like the Sun Traditional).

We use this measurement to adjust your trike to fit you out-of-the-box, but it's simple to adjust your trike later to suit your preferences. This is just a rough measurement to make things easier for you.

x-seam diagram

Alternatively, if you like reading and diagrams...

To measure your X-seam, you'll need a tape measure, a sturdy board (like a piece of plywood or an ironing board), and an assistant to help you. If you currently ride a recumbent bike, you can use that to take the measurement instead of the board.
