Sun Seeker EZ-Tad SX. Sun Seeker's EZ-Tad SX is a blast to ride everywhere! The combination of a low-center-of-gravity frame and 3 quick-rolling wheels makes this low-rider handle like nothing else. It's more than just zippy speed though. A plush, fully supportive seat offers unparalleled comfort, too. You'll also love the under-seat steering, which takes all the pressure off your arms and hands. And, this sweet rig sports powerful disc brakes and a hill-flattening 24-speed SRAM/Shimano drivetrain.
