V. ADJUSTMENTS V. ADJUSTMENTS
A. REAR AXLES - CENTER OF
BALANCE
1. Notes
a. The position of the rider’s weight relative
to where you set the rear axles
determines the center of balance.
These are the most important
adjustments on your chair.
b. You can adjust the center of balance by
moving the rear axles forward or back in
the axle plate. On the Zippie GS and the
Quickie IRIS, the axle plate itself moves
forward or back on the side frame to
adjust the center of balance (Fig 11b).
2. Reasons to Adjust
a. Moving the rear axles FORWARD in the
axle plate will lighten the force needed
to turn the chair.
b. Moving the rear axles BACK in the axle
plate makes the chair more stable.
c. Moving the Zippie GS or the Quickie IRIS
axle plate forward lightens the force nec-
essary for turning, while moving it back
stabilizes the chair.
Consult your doctor, nurse or therapist to
find the best rear axle setup for your chair.
Do not change the setup UNLESS you are
sure you are not at risk to tip over.
3. Forward or Rearward Axle Adjustment
(Figs. 11, 11a & 11b)
The center of gravity is adjusted by moving
the rear axle forward or backward to the
additional bearing position (preset with bear-
ings at the factory). For additional
forward adjustments, the axle plate may be
moved forward by inverting the axle plate
and thus giving two additional positions.

Always adjust rear wheel locks after you
make any change to the axle position.
Make sure lock arms embed in tires at least
1/8 inch when locked. If you fail to do so,
the locks may not keep the rear wheels
from rolling. Refer to User Instruction
Manual for directions.
B. REAR AXLES - SEAT HEIGHT
1. Seat Height - Quickie 2 and
Zippie 2 Only (Fig. 12)
Seat height can be adjusted by moving the
axle plate vertically in the predrilled frame
holes. This allows a 2 1/2” seat height
adjustment. Refer to User Instruction
Manual for directions.
2. Seat Height - Zippie GS Only
(Fig. 12a)
On the Zippie GS, adjust seat height by
moving the rear axle sleeve up or down
in the axle plate. 1.25" adjustment possible
(Fig 12a).
NOTE: Only 20",22" and 24" wheels available with
one-arm drive.
If you raise the seat too high, you may “out-
adjust” the caster forks. If this occurs,the
seat will tilt toward the front, and may
cause the rider to fall. To avoid this, you
will need to use a longer caster fork or
fork stem. Refer to User Instruction
Manual for directions.
3. Seat Height - Breezy Series Only
(Fig. 13)
Seat height can be adjusted by inverting the
axle block. This allows a 1” seat
height adjustment.
