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.
RETURNS & REFUNDS
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. It is also imperative that you retain the shipping pallet and box should you decide to return a complete tricycle. If these packing items are discarded, the return will become that much more complicated and expensive.
For more information on Returns, Shipping Charges, and refunds, please visit our Terms & Conditions.

With liftgate service, the truck can only lower the pallet to the ground. They cannot deliver it inside your house. You will need to open the box and dispose of the pallet afterward.
