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 JT-2000 is a recumbent foot cycle. It has a fully adjustable
recumbent seat that fits almost any adult rider. The cycle features a 14-speed
Shimano hub paired with rear disk and front hand brakes. It is designed for
comfortable riding on paved trails and roads. The multiple speeds allow the
rider to keep pace with family members and friends in most situations and
achieve higher speeds when appropriate. The cycle’s turning radius is 10 feet.
JT-2000 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.

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. 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
23.
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.
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.

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.
It is best to let a professional to replace brake shoes. If you, however, decide to
replace them yourself, remove old brake shoes and install the 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.
Before riding your tryke, always check that it is in proper working
order. Check that all quick release lock levers, nuts and bolts are
properly tightened, and that tires are properly inflated.
