How to Measure Your X-Seam

At ElectricTrike.com 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.

You can see how to take the measurement in our video here.

 

Or you can read about how to measure it in-depth here:

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.

 

Start by placing the board against a wall at 60*. You can use a protractor (or print this one out) to measure the angle, or just measure the length of your board, divide that length by 2 and place the end of the board that distance from the wall. Example: a 36" long board will be placed 18" away from the wall to get a 60* angle.

 

Now, measure the length from the end of the board to the end of your feet. This is your X-Seam.

 

If you're having trouble with the measurement or want to size your bike a different way, feel free to choose "I'm not sure" from the drop-down menu and we can discuss your needs after you place your order.

The Eco Delta SX is the most affordable SUN delta trike and it's full of features. It has a fully adjustable mesh-back saddle with a padded bottom that keeps you cool and comfortable. There are spare bottle mounts on the handlebar and seat frame.

Setting this electric trike apart from others is its traditional handlebars, higher seating position and lower cranks better suited for casual riding. This e-trike utilizes the compact yet powerful 1000w performance electric drive system paired with a 36 volt Li-ion battery pack for 20 mph top speeds and plenty of torque.
