About AmTrykes®
AmTryke® therapeutic tricycles, owned and operated by National AMBUCS™
Inc., are designed for people with disabilities who are unable to operate a
traditional bicycle. AmTryke tricycles or “trykes,” can be operated by feet,
hands or both, and include a wide variety of models. The trykes can also be
adjusted to fit the needs of different riders, including frame size, type of seat,
trunk and leg supports.
AmTryke’s 1020 Junior Handcycle provides a good mobility option for larger
riders and features an adjustable easy slide wheel chair seat for transfer of
riders. Riders who are comfortable with the normal wheelchair position find
this seat familiar and easy to adjust. This hand crank tryke operates easily and
includes a 3-speed Shimano hub for ease in riding on gentle slopes and hilly
terrain. A tight turning radius makes this tryke easy to maneuver. An adjustable
foot platform provides secure foot positioning. This tryke also features a basket
for shopping, a coaster brake for additional safe riding and a front hand brake.
1020 can be adapted with several accessories. See Optional Accessories in this
manual for more information. You can also visit our website for most up to
date information at www.ambucs.org.
About This Manual
Read this manual carefully before assembling your tryke or using it for the first
time. This manual includes important information about safety, assembly and
maintenance. Keep this manual in a safe place for information and for ordering
accessories/parts.
AMBUCS/AmTryke reserves the right to make changes to the design and
technology of AmTrykes. The assembly instructions are accurate as of the date

Safety
Safety is very important to us. AmTryke products are designed in accordance
with the latest safety standards and are constantly monitored for quality. We
use information from this quality control to develop our products.
We urge all riders to seek the opinion of their health-care provider(s) before
riding their tryke.
AmTrykes should be used for their intended purpose only.
Safe Riding Tips
Before riding, familiarize yourself how the tryke operates —it’s steering,
braking and shift gears (if applicable). Adjust the seat, handlebars and pedals to
fit the rider. Please see Fitting AmTryke for Rider section in this manual for
more information.
Here are some tips about riding safety:
•AmTrykes should be used with close adult supervision.
•Riders must wear helmets. All our trykes include a free safety-rated helmet.
The helmet must fit appropriately. A properly fitting helmet sits on the head
comfortably −a helmet that sits high on the head is too small. Some
movement is acceptable, but a helmet that moves a lot is too large. See the
illustration below for reference:
Correct Way to Wear Helmet
Wear the helmet flat atop your head,
not tilted back at an angle.
Make sure the helmet fits snugly and
doesn’t obstruct your vision. The chin
strap should fit securely and the buckle
stay fastened.

For more information about
finding the correct size helmet,
see Helmet Sizing Chart on page
18.
NOTE: Be careful not to pinch the
skin when fastening helmet buckle.

•Riders must wear shoes. If shoes have laces, they must be tied properly.
•Most trykes are equipped with a steering pin and have three steering options
available:
oFull steering: No steering pin. This option allows riders to make sharp turns
and is appropriate for riders who ride at slow speeds or in close quarters.
Close adult supervision is required.
oLimited steering: This option allows riders to turn 20 degrees in either
direction, thus, reducing the risk of over-steering or tipping over.
oNo steering: This option allows for riding straight only. A supervising adult
is required to turn the tryke.
•To avoid tipping the tryke over, approach wheelchair ramps or thresholds at
a 90-degree angle.
•Use caution on sloped parking lots, driveways and sidewalks. Avoid excess
speed by having an adult restrain the tryke from behind on sloped surfaces.
The trykes have many options for control features. Consult AmTryke to find
out the best solution for your rider.
•Many riders do not have the motor skills required to be able to use the hand
brake effectively.
•Depending on trunk stability, behavioral compliance and body awareness,
some riders may need supports (e.g., lateral, head), belts (e.g. lap, shoulder),
hip abductors or other specialized equipment. A physical therapist/health
professional can assist you with any recommendations.
•Riders should only be allowed to ride trykes that are the appropriate size. If
you are uncertain, refer to AmTryke Sizing Charts in this manual or contact a
physical therapist.
•Before riding, always check that all tires are inflated properly.
•If parts are broken or missing, the tryke should not be used until repaired.
WARNING: DO NOT RIDE IN OR NEAR TRAFFIC, OR WHERE THERE IS
A RISK OF FALLING OFF CURBS, STAIRS, POTHOLES OR OTHER HAZARDS.
WARNING: NEVER ALLOW MORE THAN ONE RIDER ON AMTRYKE.
WARNING: DO NOT RESTRAIN TRYKE BY GRABBING HANDLEBARS
OR HAND BRAKE —THIS MAY CAUSE IT TO TURN SHARPLY AND TIP
OVER.

Brakes
If your tryke has brakes (front or coaster brakes) be careful when using the
brakes. Operate the brakes gradually. If your tryke has front brakes (front
caliper brake or both front caliper brake and rear disk brake) squeeze the brake
lever(s) gradually until you feel brake(s) working. The left brake lever operates
the front caliper brake and the right lever operates the rear brake. To stop your
tryke, use both brakes. It is advisable to start braking by operating the rear
brake slightly before the front brake.
Shift Gears
If your tryke has shift gears, use precaution when shifting gears. When shifting
gears keep pedaling but reduce pedaling pressure. Do not try to change gears
when pedals or wheels are not moving. Also, never change gears while back
pedaling and do not force the gear shifter when changing gears.
WARNING: BE CAREFUL WHEN OPERATING BRAKES. SUDDEN
BRAKING MAY CAUSE TRYKE TO TIP OVER.
CAUTION: USE CAUTION WHEN SHIFTING GEARS.

Handgrips
To install the handgrips, stand in front of the tryke and carefully hand thread
the left handgrip counterclockwise and the right clockwise onto the crank arms.
When you are sure that they are threaded correctly, tighten with a 15 mm
wrench or socket.
Foot Platform
To install the foot platform to the frame, begin by putting a thick washer over a
large Allen bolt. Hold foot platform
assembly to the underside of the frame
and align holes. Start threading each
Allen bolt with thick washer by hand
until both are threaded enough to hold
foot plate assembly in place. Use the
Allen key provided to tighten the bolts
until secure.
Seat
Start seat assembly by first putting
together the seat:
1. Slide the backrest into the seat and
align the holes.
Crank arms (pictured from front)
NOTE: The handgrip with the brake lever
goes on the left crank arm and the
handgrip with the shifter lever goes on the

2. Slide a large flat washer over an Allen bolt and through the seat belt
grommet, and put the bolt through the hole in the backrest.
3. Put a small flat washer and nut on the other side of the bolt. Use a 13 mm
wrench or socket to tighten the nut. (Repeat process on the other side).
Next, install the seat to the frame:
1. Remove four nuts from the
bottom of the seat and place
the seat on the rear frame
with the threaded bolts
protruding through the seat
plate. 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.

Seat Mount Control Kit
Part #: 30-24-1424-3
Tools: 5mm Allen Wrench, Phillips Screw Driver, Scissors
This kit helps mount the brake lever and/or twist shift under the wheelchair
seat. Mounts on left or right side. This removes the cables from the handsets.
1) To begin, remove the first corner screw holding the seat fabric in
place. Once removed, it allows for space to mount the bar stub.
Slide the bar end over the seat frame as pictured below. A 5mm
Allen Wrench is needed to open and close bar end. It usually helps
to use a larger blade screwdriver to gently pry open the bar end so it
will slip easily onto the seat frame. You may have to do this as well
with the brake lever.

2) Once the bar end is installed, attach the brake lever first followed by
the grip shifter or thumb shifter (if applicable). If needed, please
follow the instructions concerning twist shift and brake found in
your tryke manual. Use the zip ties to help position cables along the
tryke frame to prevent damage during rides.
Note: Your 1020 or
1024 may have come
with a thumb shifter,
rather than the grip
shifter pictured. If so,
it will still mount to the
front corner of the
seat.

To install the basket, follow these steps:
1. Attach the basket support using two short black Phillips screws, two nuts
and two black brace brackets.
2. Attach the basket to the backside of the seat back using two clamps, two
long lag bolts and two nuts.
3. Attach the basket support bar to the rear frame using two bolts and two
nuts.
Wheel Reflectors
To install the wheel reflectors, place the reflectors in an area on the rim that is
opposite the valve stem, behind a single
spoke with two spokes on the opposite
side. Align the front of spoke with the clot
in the reflector. Insert the white pin with
the slotted end going over the spoke into
the hole in the reflector. Use a
screwdriver to turn the white pin until it
locks in place.

Troubleshooting
Here are some common troubleshooting issues with answers.
Pedals/handles will not thread into crank arms.
Check to make sure that the right pedal is used on the right side and the left
pedal is used on the left side.
Rear wheels make noise.
Axle nut(s) is too tight. You need to loosen it slightly.
Brakes squeal or rub against the tire.
Brakes are adjusted too tight. Readjust.
Cable wraps around crank arms.
Only happens when pushing backward. Hold onto cable while doing so and
direct the cables.
For other issues not answered here, please contact AmTryke at 1-800-838-1845
or email us at [e-mail].
Maintenance
Maintenance is important to help keep your AmTryke in good working order
for years to come. This section includes some general maintenance tips.
Wheels and Tires
Wobbly wheels cut braking power, so keep all wheels running true. Wheels can
lose alignment over time when spokes stretch. Wheel alignment takes special
tools and know-how, so have this done by a professional/bike shop.
Proper tire pressure is also very important. If tire pressure is too low, it can
cause a flat and rolling resistance, and if tire pressure is too high, it can cause a
tube to blow out. Keep tires inflated to the pressure marked on the tire.
Correct pressure assures longest tire life. Repair tube punctures with a self-
adhesive patch, follow instructions that came with the repair kit.
Brakes
Brake shoes wear out so inspect them at least every six months. Make sure that
they are properly aligned on the wheel rim for maximum braking power. Make
adjustments if necessary.

Documents/FileShares/FileShares/Documents/Amtryke/Manuals and Instructions -
2016/Models/1024/1020 &1024.docx
It is best to let a professional to replace brake shoes. If you, however, decide to
replace them yourself, remove the old brake shoes and install new shoes in the
brake arm. Tighten the brake shoe clamp bolt.
Chain
Clean the chain at least every six months, more often if you have been riding
your tryke over sand and dirt, or through water and mud.
You do not have to remove the chain for cleaning. You may clean the chain
with an environmentally safe chain cleaning product and brush. If you use a
solvent (such as kerosene) then remove the chain (with a chain rivet tool) and
immerse it in the solvent to avoid spilling/staining, particularly on the tires or
brake shoes.
