Socket Wrench
Extender Arm for Socket Wrench
5mm and 6mm Hex/Allen Wrenches

Step 1:
Lift Boom and connect the Boom’s Brace to Front Fork Assembly with a 6mm Hex and 13mm
Wrench. Tighten accordingly but please do not overtighten.
Step 2:
Attach Rear Deck with the 4 large bolts
found with your parts. Be sure to install
washers, followed by 14mm nuts. The
upper bolts found on top will need to be
tightened with a 5mm hex and 13mm
wrench. Note: Rear hub is on left side of
tryke.

Step 3:
Place rear wheels on Rear Deck. Make sure the Spacer (silver in color) is found on the left axle—
The Spacer helps prevent your left wheel from sliding side-to-side on the axel shaft. The Spacer is
already in place on tryke prior to unboxing, but double-check as it could have possibly slid off
during assembly. Slide wheel in place followed by a washer and large 22mm nut—tighten
accordingly with your Socket Wrench or Crescent. Tighten until snug and then back nut off by ½
turn. If wheels are overtightened, bearings will grind and make noise.
Step 4:
Place wheels on tryke. Directional arrows are found on each tire and should always point
towards the front end of the tryke. The front wheel will appear different as it will house plastic
tabs covering the wheel hub. Please be sure the Quick-Release Lever is featured on the right
hand side of tryke. Slide Quick-Release Lever inside front wheel hub with Spring in place—follow
the connection by installing the second spring on left side, followed by the nut (black in color). You
can make use of the quick-release to torque while you are tightening the nut by hand—please
tighten carefully and do not overtighten.

Step 5:
Install Chain—foot cranks to rear hub. Feed chain through the protective Chain Tubing. Keep in
mind it will need to loop around the Rear Hub (found at rear deck) and back into the second tube
towards the foot crank chain ring on left side.
7/17/2015 N:\AmTryke\Manuals and Instructions\AM-20
Step 6:
Finish feeding chain through second
Chain Tube—making sure chain is
aligned correctly over Rear Hub. If you
are experiencing difficulties in feeding
chain through protective tube, you can
use thin twine/string and/or fishing line
to help you pull the chain through.
Step 7:
Assemble Master Chain Link. Before you do, please leave enough slack to slip chain over Rear
Hub. Once you have the chain resting on Chain Ring (front left side of tryke), you can turn Crank
Arms forward to help slip the chain onto Rear Hub—one solid rotation should be enough to slip
chain over the Hub and Chain Ring—completing the loop.

Step 8:
Install Chain—hand cranks to foot cranks.
Loosen Collar Stem with a 5mm Hex. Slide
Handlebar Stem down—this gives you
enough slack to slip the chain over the
Chain Ring (right side). Once the chain is
in place, pull the Handlebar Stem back up
and retighten Collar Stem hex bolts. Be
sure Handlebar Stem is aligned with Front
Fork to straight ahead position.
*Please note: If you anticipate the need to
lower handlebar stem downward for rider,
you will need to disassemble the Master
Chain Link and remove the appropriate amount of links. We recommend contacting your nearest
bicycle mechanic for this adaptation.
Step 9:
Loosen Front Fork Steering Bar with 6mm hex (located on top). It is vital that you do not
completely remove this bolt—only loosen so that you can expose the etched/dashed lines on
Steering Bar. You should stop pulling upward at this point and focus on aligning the bar and
retightening. Attach Steering Rod to Front Fork Assembly to the Boom via 5mm hex and 13mm
wrench.

Step 10:
Four Thick Washers should
be placed on top of the Seat
Support. It is important to
note that these washers
MUST be in place in order to
slide seat forwards and
backwards—once fully
assembled. We recommend
installing rear bolts first—this
helps hold seat in place as
you install the front bolts.
Both sets require a 5mm Hex
and 13mm Wrench to tighten
properly. The pictures below
help illustrate this process.

Step 11:
Attach both Handles
and Pedals. Please
pay attention to letters
found on inside bolts
of both handles and
pedals—each bolt
indicates where the
handle/pedal needs to
be (left or right).
Handles/Pedals are
mounted onto the
hand/pedal cranks.
The right hand/pedal
tightens clockwise
and the left
counterclockwise.
Hand thread until you
are certain they are
threaded properly and
then use the
Stainless Steel
Wrench you were provided with in your box. Using the 15mm end, tighten securely.

Step 12:
Install your Seat Support Posts. There are two sections of posts. The longer of the two needs to
be installed on the Rear Deck. The shorter bar will connect to the Seat Back. Slip shorter bar
over the longer sections and tighten with a 9/16” socket and 5mm Hex. Align clip holes at the
desired location—this depends on the rider’s level of comfort. Finish by inserting Safety Clips at
desired locations. If you happen to find your seat back moves freely, then you need to double
check your Safety Clips—making sure they are aligned properly with the clip holes.

Step 13:
Attach Loading Brake—can be installed on either
right or left fender brackets on the rear deck. First
tighten bottom bolts with 5mm Hex and center it
above the rear tire or left; again depending on the
rider’s comfort level. You may find the Loading
Brake rests higher up, and when engaged, does not
reach the tire. To adjust this, you will need to
loosen the two silver nuts with a 10mm wrench.
Slide the Loading Brake down to about 2” so that
the brake rests right above tire. When engaged, the
brake should rest firmly against the selected tire;
slightly pushing it inward.
7/17/2015 N:\AmTryke\Manuals and Instructions\AM-20
Step 14:
Assemble Brake and Front Reflectors found in your parts container. Screw both brake and front
reflectors at designated sections (as shown below) with a Philips Screwdriver. Next, install Wheel
Reflectors by carefully, yet firmly, pushing the white plastic tabs into the center of reflector and
desired spoke.

Step 15:
If needed, insert the Steering Pin into the front fork tube from the side. Install the adhesive hook
strip to the frame to keep the steering pin secure from loss. Three steering positions are available:
Top position: Locks steering straight; Lower position: limits steering to 20 degrees in either
direction; No pin: free steering.
Jiggle the front wheel assembly as you push the pin into the hole and through the other side of the
fork tube. The pin should insert all the way to the split ring to be correctly seated. Note: You may
find it desirable to limit steering so the rider can concentrate on learning the pedal motion first.
Step 16:
Apply Foam Cushion to your seat and inflate all tires—keeping in mind psi pressure, which
should range between 40-65 psi (see tire wall). Use a tire inflation gauge so you do not over
inflate or damage your tubes and/or tires.
Step 17:
Lastly, inspect and tighten all aspects of your work (if needed). Before riding, double-check the
Handlebar Stem and Steering Rod and make sure it is aligned with the front tire. This keeps the
alignment straight and in order. Once you feel everything is in place, have fun riding your new AM-
20 Hand and Foot Tryke!!
