SECTION 1 - GENERAL WARNINGS
Front Wheel and Foot Contact
Brakes & Stopping Power:
WARNING
!
Improper use of the braking system, including
over-use of the front brake, can cause you to lose
control and fall. Avoid improper braking by
understanding and practicing proper application
of your brakes as explained in this manual.
e Rambo Bike comes equipped with disc brakes.
These brakes are different from other general types
of brakes associated with bikes. Some bikes
typically have rim brakes which operate by
squeezing the wheel rim between two brake pads.
Disc brakes squeeze a hub-mounted disk between
two pads. Stopping power on your bike can vary
depending on adjustments and pad thickness and
wear. Consult your bike shop about brake options
and adjustments based on your specific needs.
Do not pedal when
riding slowly if
the handlebar is
turned. It is possible
for your foot to
contact the front
tire if the handlebar
is turned while
you are pedaling.
This will result in a
dangerous situation
which may cause you to lose control and fall.
This does not occur at normal riding speeds.
WARNING
!
Contact between your foot or toe-clip and the front
wheel or fender can cause you to lose control and
fall. Avoid pedaling when turning at slow speed.
WARNING
!
Disc brakes may have sharp edges that could cut
you. Also, after extended use, your disc brakes
may get extremely hot, take special care not to
touch them until they have cooled.
Additional Brake Warnings
Disc brakes have varying amounts of stopping power
depending on adjustments and pad condition. Use
extreme caution when applying the brakes. Never apply the brakes too hard or too quickly which
could cause you to lose control and fall. Excessive or
sudden application of the front brake could pitch the
rider over the handlebars which may result in serious
injury or death.
Never ride with worn brake pads or improperly
adjusted brakes.
INSPECT YOUR BIKES FRAME AND FORK
If you notice during your pre-ride inspection that
the frame or fork has any visible damage, cracks,
dents, or problems, do not ride your bike and have
it repaired immediately. If at any time you notice a
shimmy or wobble immediately slow down and take
your bike to your local bike shop for inspection
and/or repair.
WARNING
!
A shimmy or steering wobble can cause you to
lose cont
slow down immediately. Take your bicycle to your
dealer for inspection and repair.

INSPECTION BEFORE EVERY RIDE
Before every ride, inspect the bike with the
following check list. If any part of the bike fails the
inspection, repair the bike by following the
information provided in this manual or take the
bike to your bike shop for service. Never ride a bike
with a damaged part; have it replaced.
Check the tire ination
- Make sure to check tire
pressures using a tire
pressure gauge. e tires
should be set between
7psi and 15 psi.
Tires and Wheels
- Spin each wheel and check that the tires are in good
shape with no cuts or abrasions. If these are found,
replace the tire immediately.
- Inspect the rim for trueness by spinning it and
watching for any side-to-side or up-and-down
wobble. If any movement is noted do not ride this
bike until the rim is repaired.
Brake Reach
Some bikes have adjustable brake levers. These can be
adjusted to fit each individual rider’s specific needs.
For example, if you have a short reach you may need
the levers adjusted closer to the handlebar. This
adjustment or brake lever replacement should be
done by a qualified bike technician or bike shop.
Handlebar stem and front wheel alignment
Make sure the front wheel and handlebar stem are
aligned in the proper orientation of each other.
Turn the handlebar from side to side with the front
wheel locked between your knees to test the stem
connection of the fork. If any movement is noted do
not ride the bike until this is corrected.
Inspect cable routing to be sure the handlebars can
turn freely without binding or pinching the cables.
Check to be sure that your handgrips on the handlebars are in good condition and the bars are not
protruding through the grip.
Wheel Retention System:
Some bike wheels are designed with
quick release attachments and others
are bolted directly on using a hex-nut.
Your bike comes with a bolt on style
front axle, make sure front tire is
centered on the fork. Once centered
secure wheel to the front fork with a
washer and nut on each side.
Seat Position
e saddle should be adjusted for proper t and is an
important factor in riding safely.
Place your pedals in the 6 o’clock and 12 o’clock
position. Your bottom leg should be very slightly
bent when the ball of your foot is placed on the lower
pedal. If it’s bent too much you need to raise the
saddle. If you have to rock your hips to reach or can’t
easily reach, you must lower the saddle.
Ensure that the saddle is straight and level.
Seat and seat post

position and they
do not have any
cracks or visible
damage. All
lighting should
be inspected to
be sure they have
fresh batteries and
working properly.

WARNING
!
A bike is a mechanical device. Materials and
mechanisms are subject to fatigue and stress. Over
time, components can fail once they have exceeded
their useful limits and life. Product life is often
related to the kind of treatment and riding you
submit your bike to. Hard and aggressive riding
along with neglect will shorten the projected
lifespan of your bike and its components. If not
properly maintained, your bike and its components
can fail causing serious injury or death.
Before riding fast or in more difficult conditions, try
riding at slower speeds in a flat, open lot to test the
function and performance features on your bike.
Consult your local bike shop if you have specific
needs on parts and functionality of your bike. Many
areas offer cyclist courses or classes which can be
found online or through your local bike shops.
Wet Weather Conditions
Use extra caution when riding in wet weather. Your
brakes stopping power will be diminished in wet
conditions no matter what type of brake system you
have, all are affected by wet weather. In order to
ensure you can stop safely in wet conditions, ride
more cautiously and slowly and brake earlier than
you would in normal road and weather conditions.
Never ride in storms with high winds and lightening
conditions.

Night Riding and Poor Visibility
Riding at dawn, dusk, during poor visibility or night
riding is extremely dangerous. Your reflectors are
not a substitute for required bike lights. Motorists
and pedestrians may not be able to see a bicyclist
during poor visibility conditions. Consult your local
bike shop for night riding equipment if you choose
to accept the risk of riding during these conditions.
WARNING
!
Riding a bicycle in low light conditions without
proper lighting and reectors attached to your bike
impairs your ability to see and be seen by other
motorist or pedestrians. is greatly increases the
chance you will be involved in an accident that
could lead to serious injury or death. Use a light
on the front and rear of your bike and be sure all
reectors are in place before riding in low light
conditions.
Unsafe Riding
While not all accidents can be avoided the list below
outlines a few examples of things that can decrease
your risk of serious injury or death.
- Pay attention and avoid distractions while riding
- Maintain both hands on the handlebars at all times
- A
void bike stunts and/or aggressive riding
When carrying gear make sure it is securely at-
tached to your bike and/or rack.
-
Never strap or latch any item to your bike in an area
not designed to carry gear.
- Only carry gear on your racks and within the
standard weight limits of the rack.
- Do not ride while intoxicated or using medications
which might make you drowsy.
- Never carry a passenger while riding
- Avoid riding in mud if possible, mud may cause loss
of traction resulting in loss of control of your bike.
-
Certain types of riding significantly increase stresses
and abnormal wear and tear on your bike. These are
just a few types of riding that can adversely affect your
safety and lifespan of your bicycle and components.
- competition or stunt riding
- downhill racing/riding
- jumping your bike
WARNING
!
Avoid riding too fast
Higher speeds create higher risks and greater forces
in the event of a crash. At higher speeds, it is more
likely that wheels will slip, or that a small bump can
create a significant impact to your frame or fork.
Keep your bicycle under control at all times. For
children, the limit of speed for safe riding is much
lower, so parents should strictly enforce this rule.
Off-Road or Backcountry Riding
Always use special care when riding off-road or in
remote areas. If you are unfamiliar with off-road
riding start out on moderate terrain and slowly build
your skills until you are confident you can ride on
trails and unimproved roads. Remember, keep your
bike under control at all times and never attempt an
obstacle that is beyond your skill level. Riding at an
increased speed in rough conditions greatly increase
your risk of serious injury or death.
Special Considerations for Remote Areas
- While riding on rough terrain even if a short
distance share your destination and route with
another adult
- Never ride alone in remote areas
- Carry a signaling device such as a whistle, cell
phone, or 2-way radio
- Take identification and emergency food and drink
- Wear appropriate clothing and safety gear for the
of riding you plan
type
- Carry a first aid kit
Respect local regulations and rules / Private Property
Remember each area in which you may ride your
bike may have specific regulations. Always respect
private property and never trespass. Respect the
rights of others with whom may be sharing the trail
with you; ie: hikers, cyclists, equestrians. Stay on your
designated trail and do not destroy vegetation and
minimize your impact on the environment. If you
are unsure of your local laws or regulations please
contact your local conversation officer before riding
on designated wildlife areas
