      The EZ-3 USX HD provides all the stability and control available in recumbent trike technology while offering a little more thrill. And when we say HD we mean heavy duty, with 110 psi tires, 48 spoke wheels with double-wall rims, this trike will handle 400 pounds. 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. Also, the EZ-3 USX HD offers powerful brakes on all three wheels, mid-frame suspension and under-the-seat steering. The EZ-3 USX HD might not be for the superhuman daredevil, but it is quite perfect for the casual to intermediate rider, and perfect for sunny days on the bike path or zooming down the boardwalks. The EZ-3 USX features Direct Steering, the new Slotted Seat adjustment system, and rattle-free and infinite-adjust seat struts.

      The Sun EZ-3 USX is a human-powered, recumbent, three wheeled vehicle. It engages me in a way that the Segway did not. I am amazed this product, what some call a “bent trike,” is not better known.

      What’s significant about the USX? It’s the most comfortable human powered vehicle ever, more comfortable than many cars. It’s safe, practical, and affordable. I hate exercise but I find myself impatient to get my next chance to ride this thing. The USX is potentially a major step forward in promoting conservation and healthy exercise in America.

      Riding the USX is eerie, because it feels like relaxing on a perfect easy chair and performing aerobic exercise at once. You can go fast or slow, and both are wonderful. You can load the thing with 400 total pounds. You can pull carts. Some riders have decked out USX’s with ipod sound systems and other amenities.

      There are some downsides. It’s heavy: 65 pounds. Going up hills is pleasant, but slower than on a bicycle.

      Another big plus: you sit high enough to be noticed by car drivers, though I also added a flag and extra lights to err on the side of caution. Although it looks wide, and encourages cars to give more room than is commanded by bicyclists, it is actually narrow enough to roll through a standard door. You can stand it up on end so it takes minimal room when parked. You can just stop and rest while going up hill- it has a parking brake.

      There are lots of other bent trikes — dozens — but most are “performance-oriented” — made for athletes. Some of the athletic brands are
      ICE, HP Velotechnik and , Catrike. I have tried some of them, and I think they are fun and interesting, but not what I want. Some of them are expensive, very low slung (you’re practically on the ground while riding), and not so practical for non-atheletes. What I want is something that’s super easy to get in and out of, that’s fun to sit on while standing still, that’s high up enough to be safe around cars, and that is fun to ride slow. I want something for life, not for sport, and there’s not much competition in this niche. There is another interesting comfort-oriented bent trike, the Hase Leupus, from Germany.

      Beware that sometimes enthusiast cults get lost in fantasy. The enthusiasm in the bent trike world sometimes reminds me of what happened with high-end consumer audio. Superstitions crowded out reality. People started to spend insane money on audio cables with impossible physical properties.

      Even though the USX is ridiculed by some hard-core bent bike enthusiasts, it is an important product, even aside from the low price.

      A big help with my weight loss

      <p>So I have had my Sun USX Trike for over two years and almost rider it every day. This trike has changed my life all for the better. When I got my trike I weighed 420 Lbs. which is slightly over the max capacity of 400 Lbs. I had a health scare that help motivate me to lose weight and start eating healthier. My wife was a big help with all her support which help motivate me to get out and rider my trike on the days I did not feel like riding. I have lost 100 Lbs and feel so much healthier, my wife does not have to motivate me any longer, I love to go ride my trike and I know it has been such a big part in helping me loose the weight. The trike is very sturdy and has performed well. I tried a Tadpole style trike and I felt it was two difficult for me at when I purchased my USX but I am sure now I could rider either style of trike. After my first set of tires wore out I replaced them with Schwalbe Marathon Plus Tires which have been fantastic, no flats. I did have to replace my mesh seat back which ripped and the fabric on my seat is starting to look a bit worn, but I realize I am a bit rougher because of my size that the average trike rider.</p>

      Quality Heavy Duty Recumbent

      <p>I purchased the Sun USX HD trike over the summer. I need a heavy duty trike that would handle my weight (390 Lbs) and be able to be ridden on a gravel road. What attracted me to the trike was the heavy duty wheel with extra spokes, wider tire than other trike and a shock absorber in the center of the frame which does a nice job at smoothing out the bumps. I also like the Delta designed trikes more than the Tadpole design that I tested because the Delta trike are easier to get on and off of. The Gel seat and adjustable back rest makes this trike very comfortable. The components are good enough for my riding style and I thought the price was very reasonable for a heavy duty recumbent.</p>


      <p>It has to be the best bike for a senior. I'm 67 with a herniated disc bad shoulders morbidly overweight (well.....350lbs). I am lazy. Sometimes when I ride.......people walking will pass me by. Of course I only ride on, nice bike paths, but if you gear down to the lowest gear, you can ride just fine on most dirt paths or grass. Sand may give you problems, but so far, I have never had any problems. The only thing I have to figure out is how to rig a cup holder on my handlegrips....I have gone up a fairly steep paved hill, only my weight and physical condition slowed me down, but I made it up the hill just fine.</p>
