bought a three wheeler to try and get back into shape. The usx has a nice upright seat and is pretty comfortable to ride. I typically ride between 30 minutes and an hour and do not experince any discomforts. the steering takes a little bit to get used to. My biggest complaint is the grip shifters, I much prefer the trigger style shifter and I wish they were an option for this trike.

I had a very bad knee ,painful for walking, and I read about biking instead of walking.

This is the perfect trike because it is a recumbent and does not hurt my knee at all. My legs are as strong as they were in high school and I am 76. I bike seven to eight miles a day and more on Saturdays. This is a great bike for seniors. I had this bike for four years and it is my prized possession!

We have a bikers group and as they age, more guys and gals are getting this model.

The Sun Seeker EZ-3 USX HD suited my needs for a heavy duty recumbent. I am close to 400 Lbs which limited me to just a couple of recumbent. The Terratrike Rove, Trident Titan and the Sun USX HD. I had a bit of trouble getting around the cranks on the Rover and Titan and was afraid of falling which led me to the Sun USX HD. The USX was just easier to get on and off which made my choice easy. The USX HD is a heavy duty trike, that is what the HD stands for. The USX HD has a 400 Lbs capacity and I am sure the frame and wheel could take a lot more weight than that. I would bet the shock, rear axle or seat bottom is probably the limiting factor. My trike has forty eight spokes in the wheel where as other trikes have only thirty six so I know my wheels are very strong and can handle my weight. The frame is made of steel and is very strong and should easily be able to handle 400 Lbs plus. My trike has twenty one speed which are enough for my needs.

I like that the trike has two rear disc brakes one for each rear wheel and a front brake as well. The two rear brakes have a soft feel to them, I would prefer that they felt more like the front brake. I wish the handlebar were adjustable for width not just forward and backward. I also feel the handlebars a back a bit far for my taste but that might be ok if you are taller than I am. I would have like to seen an upgrade to the shock, like and air shock so it would be more adjustable. The trike seems to be a fair amount heavier than other trikes that are designed to carry 400 Lbs.
