    What does X Seam mean and how do you measure it on these KMX Trikes?

    Measuring your X seam:
    See diagram below:
    Lean a board against a wall at the recommended angle (approx 12" - 16"). 
    Sit tight against the bottom of the board, lean back and straighten your legs with your toes pointing upwards.
    Measure the distance from the front of the board to the bottom of your shoe. This will give you your X seam measurement.
