    Features

    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 110psi tires, 48 spoke wheels with double-wall rims. The direct-drive motor is also heavy-duty and designed for heavier loads with 1,000 watts of peak power.

    Advanced Mid-frame Suspension

    The mid-frame coil-over suspension on the EZ-3 HD helps smooth the roughest roads and keeps you riding when other trikes would give up.

    Heavy-Duty Construction

    With 48-spoke double-wall alloy rims, high pressure tires, dual rear disc brakes and front v-brake, the EZ-3 HD is built for a 400lb capacity with a low center of gravity.

    Easy-To-Read Segment Display
    The EZ-3 HD 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.
    Cambered for Stability
    The EZ-3 HD's Frame Geometry Features cambered rear wheels – this adds extra stability for easy and safe cornering by tilting each rear wheel inward towards the center of the frame by 2 degrees.
    Heavy-Duty Direct-Drive Motor
    The 500-1000w E-BikeKit motor is capable of puling over 300lbs and is laced into a USA handbuilt wheel with single-butted 12-13 gauge spokes for durability. This motor is seriously heavy-duty.
    Thumb Throttle
    The EZ-3 HD features an easy-to-use thumb throttle, so you can get power when you need it. The integrated pedal-assist sensor can also give you a boost to augment your pedaling.

    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.

    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.
