Comfortable Upright Handlebars

The Electric Eco-Delta puts the handlebars within comfortable reach – the adjustable handlebars are high and close to the rider, providing a more familiar and secure ride than recumbents with under-seat steering.

Rear Disc Brake

The Electric Eco-Delta features a rear Promask DSK-400 mechanical disc brake and front v-brake – this economical combination gives safe, long-lasting brake performance.

SINET™ Smart Display System

The new SINET™ color LCD display delivers clear, easy-to-read ride information with a modern high-contrast screen designed for everyday visibility. Riders can quickly switch between three different display screens showing speed, battery level, voltage, trip distance, range, power output, average speed, and more. Combined with the SINET™ sine wave controller and integrated torque sensing, the display gives riders smooth, intuitive control over assist levels, cruise control, and riding performance — all from a simple handlebar-mounted interface.

Simple 1x7 Gearing

Even if it's been a while since you rode a bike, you'll appreciate the Eco-Delta's simple 1x7 gearing. This system means every gear you need is available at the flick of the wrist. No need to worry about double shifting or gear combinations!

500-1000 Watts Geared Hub Motor

The 500-1000w E-BikeKit front geared hub motor features impressive 84Nm torque and a USA handbuilt wheel with single-butted 12-13 gauge spokes for durability.

Throttle-On-Demand

The easy-to-use thumb throttle allows you to engage the motor whenever you need it. Use the throttle to get a boost when starting from a stop or to help get up to cruising speed. The Eco-Delta also features a pedal-assist sensor (PAS) for operation.

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.

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.

$300 FLAT-RATE SHIPPING

The Contiguous USA Only.

SALES TAX

Sales tax will be applied by the state where applicable.

SHIPS 100% FULLY ASSEMBLED and Ready to Ride 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 $300) 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.
