The EZ-3 USX HD is designed for riders who want maximum comfort, stability, and confidence — especially for longer rides, larger riders, or everyday utility use.

Advanced Mid-Frame Suspension

The mid-frame coil-over suspension on the electric EZ-3 USX 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 a front v-brake. The electric EZ-3 USX HD can handle 400 lbs, including rider and cargo, and is balanced with its low center of gravity.

Easy-To-Read Segment Display

The EZ-3 USX HD features an easy-to-read backlit display with large text mounted on the handlebars. This advanced segment color LCD includes a battery meter, speed and trip distance readout, and programmable top speed limit.

Cambered for Stability

The EZ-3 USX HD's frame geometry features cambered rear wheels which add extra stability for safer cornering. Each rear wheel tilts inward towards the center of the frame by 2 degrees.

Heavy-Duty Direct-Drive Motor

The 500-1000 watts E-BikeKit motor is can pull over 300 lbs, and the wheels are hand built in the USA with single-butted 12-13 gauge spokes for durability. This is a seriously heavy-duty motor.

Thumb Throttle

The EZ-3 USX HD features an easy-to-use thumb throttle, so you can use the power when you need it. The integrated pedal-assist sensor can also give you a boost to augment your pedaling.
