Features

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.

An upright and a comfortable reach handlebars
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.

Promask DSK-400 mechanical rear disc brake
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.

A large easy-to-read LCD screen
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 1x7 gearing makes it easier to shift
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!
An e-bikekit front geared hub motor
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.
Use the throttle to boost your speed
Throttle-On-Demand
The easy-to-use twist 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.

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.
