EZ-3 USX Recumbent Tricycle

Sun USX Delta Recumbent Tricycle Built for Comfort - Not Speed
The EZ-3 USX HD has the stability, comfort and control of a recumbent
trike. Starting in 2009 the Sun EZ USX became the Sun EZ USX HD. HD is
for heavy duty, this trike is warranted for riders up to 400 lb. It is
by far the least expensive trike I know of with a warranty weight over
300 lb.
The USX HD is also the least expensive delta trike with Under Seat
Steering (USS). Some riders find the under-the-seat steering offers a
more relaxing arm position. The only way to know if you like USS is to
try trikes with USS and OSS (Over Seat Steering). The USX can be
adjusted to fit riders from about 5’ to about 6’3”. Its 21 speeds allow
most riders to (slowly) climb most paved hills. Beware the 3 speed
recumbent trikes if you ever want to climb hills. The 3 speeds just
aren’t enough to get a heavy trike up a hill. Several of our customers
just love their USX trikes, but they don’t typically ride over 10-20
miles a day and certainly don’t race.
The USX, like the EZ-3 AX has a lower seat than the Sun EZ-3, and the
rear wheels are cambered giving a low center of gravity to increase
stability when cornering. Three 20-inch wheels mean only one size tire
and tube so you can get matching replacements easily. Its three-wheel
brakes stop this trike well.
The EZ-3 USX is too heavy for an enthusiast and not stable enough for
the daredevil, who may tip one over. The EZ-3 USX is for casual riders,
perfect for sunny days on the bike path and tooling around the
neighborhood running errands while getting in shape.
The USX frame has a hinge in the middle with a spring on it. This
feature makes it foldable and gives some suspension.
As a folding trike it is poor, it does not fold quickly or get very
small. Tools are required to fold it and it does not fold up small
enough to fit into the trunk or back seat of a mid-sized sedan. It is
the least foldable of the foldable trikes. Want easy folding? See the
Greenspeed GT3 or
Trice
trikes. They fold more easily, get smaller and are much lighter to lift.
They also cost 3 to 4 times as much as the EZ-3 USX HD.
The USX has a spring suspension, but the suspension does not do much to
absorb bumps, especially for taller riders who sit right over the rear
wheels. Looking for a suspended (with suspension) trike? Check out the
Hase, Lepus or
Trice trikes. They
have much better suspension and are lighter but cost 3 to 4 times as
much as the USX HD.
I have been pretty critical of the Sun USX here, I just want to point
out three things:
-
It is in no way a performance trike.
-
Its suspension doesn’t do much to absorb bumps
-
Its folding feature is mot or less useless.
The USX HD is a rugged, comfy, fun and relaxing trike that is easy to
get used to. As I said previously, several of our customers just love
their USX trikes, but they don’t typically ride over 10-20 miles a day
and certainly don’t race. Try one and see if it is the trike for you!

If you can’t find a Sun dealer in your area we can have one sent to a
bike shop in your area. We can usually work with your bike shop so we
pay their assembly fee.
NOTE: Sun does not allow us to ship their bikes to customers
in the US. If you live too far away from us to come test ride and cannot
find a Sun dealer in your area we could ship the Sun recumbent of your
choice to most any bike shop near you for assembly. We usually can
arrange to pay the shop for the assembly.
