The Eco Delta SX is the newest edition to the Sun Seeker delta trike family. This is our most affordable trike, but just because its affordable doesn’t mean that it is not full of features. It has a fully adjustable mesh-back saddle with a padded bottom that keeps you cool and comfortable on long outings. There are spare bottle mounts on the handlebar and seat frame to let you carry plenty of hydration for the long hauls.
