Features
The Eco-Tad SX is the most affordable Sun Tadpole 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 Electric Eco-Tad features comfortable direct-steering handlebars. This allows for a familiar, natural hand position with higher handlebars than some under-seat steering recumbents.
The Electric Eco-Tad features independently controlled dual front disc brakes – this gives safe, long-lasting brake performance.
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 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.
