The standard nylon bearings can be upgraded to all steel bearings for improved wear
and service life. Wheels and bearings can be quickly swapped out in minutes with basic
hand tools.
3. First Set-Up Assembly
The first time you assemble the GRAZhopper, it is helpful to have a few tools handy: a
rubber mallet; two wrenches in 1/2”, and two wrenches in 7/16”, or two adjustable
wrenches to attach or tighten various bolts and nuts; and a flat head screwdriver. Estimate
1 to 2 hours to assemble and hang test your GRAZhopper for the first time.
To begin assembly of the GRAZhopper:
3.1 Start by separating and checking the parts: the
main frame, the wheels, the front fork components, the
roll bar components, all hardware, and the harness(es).
The small footprint of the basic components makes for
simplified and inexpensive shipping of the GRAZhopper.
3.2 Fill the Rolleeze wheels with the correct air
pressure as listed on the tire.
ATTENTION:
Do not over-inflate the Rolleeze wheels.
This could damage them. Be careful to not leave the
Rolleeze wheels in the sun on a warm summer day or in
a hot vehicle. Also, be careful when traveling to high
elevations. The tires could burst or be damaged due to
over-inflation from high temperatures or drastic changes
in altitude.
3.3 Assemble the roll bar components with the
supplied hardware. See photos in this manual for
specific details.
3.4 Attach the front wheel onto the fork. See photos in
this manual for specific details.
3.5 Attach the roll bar to the main frame. See photos in this manual for specific
details.
3.6 Open up the GRAZhopper. Begin by vertically standing the trike up on the front
wheel, facing and holding the underside of the trike. Next, undo the velcro strap that
holds the trike and cables together. Next, with both hands, carefully balance the trike
by holding the rear wheel axels, one in each hand. Next, lower the trike onto its
wheels by pulling out and lowering the rear wheel axels
to the ground. Next, release the quick release pin on the
end of the roll bar. Next, undo the turn buckle and place
the cable on the back of the main frame. Next, lift the
center frame up and around the roll bar and between
the tabs of the roll bar. Next, align the quick release pin
to connect the roll bar to the lower hole of the main
frame vertical support. Next evenly tighten the
turnbuckles to the point where the cables have just a
little slack and play. The cables should be a little loose,
but the trike structure should be complete.
3.7 Attach the rear wheels. First check the clevis pin is in the correct hole (for standard
12” (30cm) wheels use the outer hole, for the 16” (42cm) or 19” (49cm) wheels use
the inner hole). Next, insert the wheel bearings into the wheel axel with the stem
facing outwards. If you encounter resistance with the wheel bearings going into the
axels, use a rubber mallet to lightly tap the wheel into place. Next, secure the wheel
with a clevis pin and ring in the outer hole.
3.8 Align the rear wheels. First, be sure the cables are loose. Next, loosen the thumb
clamp on the wheel axels. Stand directly over the large main cable and visually follow
