    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.

    SHIPS 100% FULLY ASSEMBLED from Our Warehouse in Bucks County, PA
    The tricycle is enclosed in a heavy cardboard box and fastened to a custom-built shipping pallet. Shipping is by freight truck with liftgate service included.

    We use a variety of freight carriers based on your shipping destination. When the trike ships you will receive an email from us with tracking information. The freight company will contact you before the final delivery is made in order to arrange the drop-off with you.

    The electric tricycles we offer are high quality tricycles assembled by professionals with years of experience, and we stand behind each electric tricycle we build and ship. If, for any reason, after purchasing your electric trike, you are not 100% satisfied, simply contact customer service to discuss the return.

    IMPORTANT: Buyers may return any undamaged and unused products (including fully assembled electric tricycles) within 30 days of delivery for a refund minus a 25% restocking fee (based on the condition of the returned item and at the sole discretion of EBT). ACTUAL ORIGINAL SHIPPING CHARGES (not the flat-rate $250), AND RETURN SHIPPING CHARGES (back to our facility) ARE THE SOLE RESPONSIBILITY OF THE BUYER. These return shipping costs can be significant.
