5. Install Loading lock. Slide loading
lock on the loading lock rod on the
rear frame assembly. Top of loading
lock should be flush with the top of
tube. Take care that the lever is not
touching the tire. The handle is in
line with the tire and points towards
the front of the tryke. Tighten with
10mm wrench. CAUTION: Loading
lock is not for braking during
riding! Loading lock is only for use
in transferring rider onto tryke
when stationary.
6. Handlebars. Install the handlebar set. Insert
the handlebar stem into the top of the front
fork. Make sure the stem is inserted so that the
hash marks on the stem are inserted into the
fork. You should not be able to see the hash
marks when installed properly. Tighten the
stem tube at the top using the hex key
provided. NOTE: handlebars may be installed
with stem in either direction to accommodate
smaller or larger riders.

8. Seat Back Adjustment.
Once the seat is installed you
can position the seat back by
loosening the adjustment
screws located on the bottom
of the seat. The seat back
slides along the chrome tubes
underneath the seat. When
positioned correctly for the
rider, tighten the levers
securely.
CAUTION: FINAL ADJUSTMENTS FOR RIDER’S SIZE MUST BE COMPLETED
FOR SEAT AND SEAT BACK ASSEMBLY AND FULLY TIGHTENED BEFORE
RIDING OR INJURY COULD RESULT!
9. Install Pedals. Pedals
are labeled R (right) and
L (left) on the ends of
the pedal axles. The
right pedal installs on the
foot crank labeled “R”.
Note: the right side
threads clockwise to
tighten. The left threads
counter clockwise to
tighten. DO NOT
FORCE! Hand thread

Revised Date: 4/30/09 Page 7 of 10
until you are certain threads are installed properly. See Figure 16. EASY TIP: Pedal
threads tighten towards front of bike no matter which side you are on! Use 15mm
wrench to tighten.
10. Install Pedal
Leveler String. The
pedal leveler string
threads through tubes
on the bottom rear of
each pedal. First,
install the pulley
assembly in the top
of the rear deck
assembly. The hex
head screw fits into
the hole at the top of
the frame. Start the
pedal leveler cord at
one pedal, thread
through the pulley
and then through the
remaining pedal. Pull the cord tight and either knot the end or pinch the end of the cord
using the small tubing. Use a pair of heavy pliers or a crimping tool to compress the tube.
Trim off the excess cord.
11. Install Steering Pin.
If needed install the
steering pin with loop
strap into hole in
front of fork. The
loop strap attaches to
hook strap on top of
frame so the part will
not be misplaced. The
top hole locks the
steering straight. The
lower hole allows
approximately 20-
degrees steering in
either direction. You
may find it desirable to limit steering so the rider can concentrate on learning the
pedal motion at first. Jiggle the front wheel assembly as you push the pin into the hole
and through the other side of the fork tube. Pin should insert all the way to the split ring
to be correctly seated.

12. Accessories. There are many optional
accessories for the Snappy AmTryke®. Here
is a sample listing of some ideas for use with
this model.
a. Small or Medium laterals. Use
these for additional trunk support.
Small (#30-1501) or Medium (#30-
1502)
b. H-Harness. The standard H-Harness can be added to the Snappy seat back.
Specify 8-inch (#30-0337) or 11.5-inch (#30-0336).
c. Blue bucket chair seat. The small blow molded seat can be substituted for the
full support
Snappy seat. This
option costs less
and comes
standard with the
seat belt.

Fitting the AmTryke® tricycle to your Child
Note: You may need assistance while fitting the tryke to your child.
1. Engage the loading lock.
2. For Snappy seat option. Place child in saddle seat. Slide seat back assembly forward or back to
suit your child’s needs. Tighten spring release levers on underside of seat assembly.
3. With feet in pedals slide rear deck assembly along horizontal frame to the length that when leg is
extended the knee is slightly bent. Be careful not to extend frame so far that the knee locks
when extended.
4. Tighten knobs until frame is snug (no wobbling).
5. Use the two hook and loop straps to help your child keep their feet on the pedals. Pedal blocks
can be used to build up either side if needed. If you add more than one pedal block, you will lose
the heel trap. In that case, you can add optional plastic foot cups. Medium size works great with
the Snappy foot plates.
