The EZ-3 USX HD provides all the stability and control available in recumbent trike technology while offering a little more thrill. The HD stands for heavy duty, with 110 psi tires, 48 spoke wheels with double-wall rims. The direct-drive motor is also HD and designed for heavier loads with 1000 watts of peak power.
Setting this trike apart from others is its low center of gravity attained by three 20-inch wheels that are cambered in the rear to increase cornering stability. The EZ-3 USX HD offers powerful brakes on all three wheels, mid-frame suspension and under-the-seat steering. The EZ-3 USX features Direct Steering, the new Slotted Seat adjustment system, and rattle-free and infinite-adjust seat struts.
