1.2. Safety First
Riding the GRIT Junior requires some practice. It will likely take a few rides before young
riders feel comfortable with the motions. After that, they’ll be able to work on more technical
terrains and maneuvers, build up their strength, and incrementally increase their distance. We
hope that from day one onward, your young rider and family can have a great time with your
new chair.
This guide holds important safety information. Please read through it before starting your rst
ride.
Like with any mobility device, riding the GRIT Junior involves the risk of injury. By choosing
to ride the GRIT Junior, you assume responsibility for this risk, so it’s important for you to
practice safe riding. Safety information can be found in the following formats:
WARNING: Warnings indicate a potentially dangerous situation. Failure to heed these
warnings could result in serious injury or death. For example:
4
WARNING: TIPPING IS POSSIBLE, especially when going uphill. One way to prevent
this is for the rider to ALTERNATE lever strokes during ascents, instead of pumping both
levers at the same time. Riders should always wear a helmet and ride with an adult who can spot
them from behind. Total independence in the GRIT Junior may come, but safety must be the
priority.
CAUTION: Cautions indicate a potentially hazardous situation. Failure to heed these
cautions could result in minor or moderate injury. Cautions also indicate unsafe practices and
conditions that may damage your GRIT Junior or void the warranty. For example:
CAUTION: Any fall can be dangerous. Always wear a helmet. Always be aware of your
surroundings. This manual does not cover every possible dangerous situation or improper use of the
GRIT Junior. You and the young rider are responsible for your own safety and accept all risks
associated with using the GRIT Junior.
1.3. Intended Operator
• In order to safely operate the GRIT Junior independently, certain levels of upper body
strength and control are required. Grip strength is required for braking and turning, but
adaptations can be made, such as using Active Hands gloves to pull the levers back for
braking and turning.
• It is your responsibility to determine if the GRIT Junior is right for you. If you are unsure,
consult with your physical therapist or medical advisors prior to riding the GRIT Junior.
• The GRIT Junior can be modied to accommodate riders of dierent shapes and sizes. If
your young rider isn’t comfortable in the chair you’ve received, contact GRIT and we’ll be
happy to help.
• The GRIT warranty covers only the original owner of the chair. Subsequent owners will
have access to the GRIT support team but will not be covered under the initial warranty.
modications and adjustments can be made to maximize your performance.

2.2. Unpacking the Box
Save the box! The original packaging is used for returns under the GRIT Guarantee. We hope
you love your GRIT Junior, keep it, and end up recycling the box, but it’s helpful to save the
box during the rst 30-day period.
Step 1: Remove the wheels, seatback, levers, footplate, front wheel, and cushion from the box.
Step 2: To remove the main GRIT Junior frame, lift it up to reveal the footplate clamp, which
will be securing one of the cardboard inserts. Remove the clamp by loosening the clamp and
pulling it away from the chair (try twisting it to free it). Remove the cardboard insert and
reattach the clamp. Note: The clamp has a lip on it, so it can only be put on the tube in one
orientation.
Please use the following images to complete these rst 2 steps:
a) The frame is attached to the
bottom of the box.
b) Lift the frame to expose the clamp
holding it in place.
c) Slide o the clamp to free
the frame.
d) Orient the clamp so that the lip
is at the bottom.
e) Slide the clamp onto the frame.
