The most affordable electric Eco-Delta SX


Based on 3 reviews Write a review


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.

The adjustable handlebars are within a comfortable reach on the electric Eco-Delta SX.
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.

With a rear disc brake and front v-brake, this electric Eco-Delta SX will stop on a dime.
Rear Disc Brake

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

The large easy-to-read LCD is attached on the electric Eco-Delta SX.
Easy-To-Read Segment Display
The Electric Eco-Delta features an easy-to-read backlit display with large text mounted on the handlebars. This advanced segment LCD includes a battery meter, speed, and trip distance readout, and programmable top speed limit.
The electric Eco-Delta's 7-speed gearing is a easy to use.
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!
Using the E-BikeKit front geared motor, the electric Eco-Delta SX trike is built for power.
500-1000 Watt 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.
Boost forward with a simple throttle action onboard the electric Eco-Delta SX.
The easy-to-use twist throttle allows you to engage the motor whenever you need it. At a stop position, use the throttle to boost forward or help you get up to a cruising speed. The Eco-Delta also features a pedal-assist sensor (PAS) for operation.

How to Measure Your X-Seam

At Electric Bike 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 change 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 measurement instead of the board.
