Sun Seeker EZ-3 USX HD Review on December 17, 2020
Every trike has it place and every person can find the perfect trike for their needs by doing there home work. The Sun Seeker EZ-3 USX HD can be the perfect trike for someone who is mobility challenged or over 300 pounds. The HD at the end of the USX name stand for Heavy Duty and that is exactly what this trike is all about. Sun Bicycle the manufacture of the USX HD is the largest manufacture of adult triycles in the world and have been building trikes for over fifty years. Sun trikes are at the lower end of the market cost wise compared to other brands yet still offer good quality.
Frame: The frame is TIG welded together out of steel and is heavy and a bit overbuilt compared to other trikes on the marker. The USX HD is capable of carry very heavy loads; you should have no worries about the durability of this frame no matter how heavy the rider.
Paint: Any color you want as long as it is silver. The paint is more the adequate, sprayed on evenly with a nice finish. The paint should last the life of the trike even if you live in a harsh weather environment.
Drive Train: The Drivetrain is a 21 speed Shimano with a grip type shifter. The Drivetrain is an entry level Shimano and works adequately for an entry level rider.
Brakes: The Sun USX HD has unique brake system where the right brake lever controls both the rear brakes. The rear brakes are disc that are attached to each wheel. The left brake lever controls the front brake and both brake levers have a parking lock. For people with special needs the brakes can be switched from left to right or if someone just prefers to have the rear brakes controlled by there left hand it can easily be switched. The brake have good stopping power and stop the trike sufficiently while not marking the trike pull to one side or the other.
Seat: People find the seat on the Sun USX HD very much to there likening. The bottom is very wide and uses a very nice soft gel material. The seat back is independent from the bottom so the back can be positioned very upright if someone so desires. The seat back is made from a very breathable mesh so your back should not get hot and sweaty.
Wheels: This is where most problems happen with trikes. The Sun USX HD wheels are exceptional, and I will go so far as to say that they are the strongest recumbent wheels on the market period. The Sun wheels have 48 spokes per wheel where most trikes have 32 or 36 spokes per wheel. The rims on the Sun USX HD are also wider and heavier duty than rims on other brand trikes. Sun also chose a premium tire the Maxis Hookworm which is wider and more durable than most tires used on other trikes. The Hookworn tire has a smooth tread to improve the roll of the trike an can be inflated all the way up to 110 Psi. Sun also chose a heavier duty read axle which can withstand significantly more punishment than standard diameter axles.
Ride: The Sun USX rear wheels are cambered giving the trike increase stability when cornering. The USX frame is hinged in the middle with a shock absorber which smooths out the ride considerably over a rigid frame. The trike handled well and the steering had a light feel to it. I am sure Sun Seeker had a target person in mind when they were designing this trike. The trike can fit people and X-Seam between 36 and 47 inches.
In conclusion: I think this trike could be a good choice for someone over 300 Lbs, if you weigh less than 300 Lbs you should probably look at some lighter more efficient trikes.
Pros: Full Suspension, Strong, Durable, dependable, comfortable and built to last.
Cons: Heavy and slow, handlebars feel a bit awkward on the placement if the seat is in a very upright position. Not stable on down hill compared to a tadpole style trike.
