SECTION 1 – GENERAL WARNINGS

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.

The 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.

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.

Front Wheel and Foot Contact
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.

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 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 control and fall. If you experience a shimmy, slow down immediately. Take your bicycle to your dealer for inspection and repair.

TRANSPORT OF BIKE
– Always remove battery from bike before transporting
– Never lay your bike on the chain side

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 inflation

• Make sure to check tire pressures using a tire pressure gauge. The tires  should be set between 7psi and 15 psi.

CAUTION
Never set PSI below 7psi or above 15psi.

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.

WARNING

A wheel attachment device that is not properly adjusted and closed may allow the wheel to be loose or come off unexpectedly, causing you to lose control and fall. Make sure the wheels are properly attached before riding the bike.

Wheel Retention System:
15QR: 15mm Aluminum Quick Release Axle

• Slide hub into the fork and line up with axle holes

• Apply grease or anti-sieze to the entire axle

• Slide axle into the fork/hub from left hand side (disc side)

• Gently turn the axle clock-wise to connect to the lock bolt threads in the right side of the fork

• Turn the axle to the fixed position. Tighten the axle to 15mm, then press the lever to the closed position.

• If adjustments are needed, pull open the axle lever and remove the Grub screw. Next, adjust the lock bolt on the axle to the proper position.
  

• Install the Grub screw into the location dimples of the lock bolt. Tighten the axle to 15mm and press the lever to the closed position. Note: Make sure to keep the “location dimples” in line with the Grub screw hole in the fork. You should be able to see the location dimple by looking down the hole.

• Check that the disc brake operates properly.

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.

CAUTION
Disc brakes and discs get very hot during use and could burn skin. Also, the disc edges may be sharp and could cut skin. Avoid touching the disc or disc brake when hot, or when rotating.

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.

Seat Position
The saddle should be adjusted for proper fit 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’teasily reach, you must lower the saddle.
Ensure that the saddle is straight and level.

Seat and seat post
Check that the seat is securely mounted on the seat post by lifting up and down on the seat. This should not tilt or move. Next, check the security of the seat post in the frame by attempting to rotate the seat.  If the seat rotates, then the seat tube is not properly clamped in to the frame.

Check the lights and reflectors
Make sure the reflectors are mounted in the proper 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.

Check frame, fork, and components If you notice that the frame or fork has any visible damage, cracks, dents, or you hear any unusual noises while riding or other problems, do not ride your bike. 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. Carefully inspect your bike before and after each ride.

Certain types of impacts can affect the components of your bike and cause them to fail unexpectedly .After any impact or crash, thoroughly inspect all the parts of your bike for damage. A crash or other impact can put extraordinary stress on the bike. An impact or high force is any situation such as hitting a hole or obstacle in the road, such as a bump or curb.

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.

RULES FOR SAFE RIDING

You must ensure that you understand the safe operation of this bike and follow all traffic, bike laws and regulations in the area in which the bike is being operated. These may include rules regarding helmets,  reflectors, and lights. A few important general rules for riding include but are not limited to:

• Wear a helmet that meets ASTM or CPSC safety testing requirements
• Have reflectors and lights installed on your bike
• Use proper hand signals
• Avoid loose clothing
• Ride on the correct side of the road with flow of traffic
• Always wear bright color and reflective clothing
• Ride single file if riding with others
• Obey all traffic laws and regulations
• Watch for parked car doors opening unexpectedly
• Watch for pedestrians stepping out, pets and children playing near roadways
• Never carry a passenger
• Never ride with earbuds or headphones
• Always obey traffic signals
• Use caution when crossing railroad tracks and carefully cross at a 90 degree angle
• Mount a horn or bell on to your bike to signal others of your approach

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 lightning 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 reflectors attached to your bike impairs your ability to see and be seen by other  motorist or pedestrians. This 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 reflectors 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
• Avoid bike stunts and/or aggressive riding
• When carrying gear make sure it is securely attached  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
• A void riding in mud if possible, mud may cause loss of traction resulting in loss of control of your bike.

WARNING

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

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.

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

WARNING

A bike like any mechanical device is subject to fatigue, stress and wear. Over time and due to use, the frame and its components can fail. The environment and type of riding the bike is subjected to can greatly reduce its useful lifespan. If proper care and main tenancy are not performed your bike and/or its components can fail causing serious injury or death.

SECTION 2 – GENERAL RIDING INFORMATION

Once you have inspected your bike and all components are in proper working condition, you are ready to test ride your new bike. A few important general rules for riding include but are not limited to:

• Strap on your helmet that meets ASTM or CPSC  safety testing requirements
• Have reflectors and lights installed on your bike
• Use proper hand signals
• Avoid loose clothing
• Ride on the correct side of the roadway with flow of traffic
• Always wear bright color and reflective clothing
• Ride single file if riding with others
• Obey all traffic laws and regulations and traffic signals
• Watch for parked car doors opening unexpectedly
• Watch for pedestrians stepping out, pets and children playing near roadways
• Keep a safe stopping distance between you and other vehicles
• Never carry a passenger
• Never ride with earbuds or headphones
• Use caution when crossing railroad tracks and carefully cross at a 90 degree angle
• Mount a horn or bell on to your bike to signal others of your approach.

Braking
Your bike is equipped with two hand brakes. One hand brake operates the front brake and the other operates the rear. Take time to   familiarize your selfish which hand brake stops each wheel. You can complete this task by spinning the front wheel and squeezing each brake lever one at a time to determine which one stops the wheel from spinning; this would be your front brake.

When preparing to slow down or stop, gently apply both front and rear hand brakes at the same time being careful not to over apply the front brake which could cause you to lose control and fall. Before riding your bike for the first time please follow the “Brake Burn in Procedure” in your owners packet. For more information on your brakes, please review the Tetra brakes manual in your owners packet.

WARNING

Avoid applying sudden or excessive force to the front brake system. Doing this can cause your front wheel to lock up and your rear wheel could lift up and lose contact with the ground. Slide your  weight back on the seat and apply pressure to both the front and rear brakes at the same time.

Shifting
Your Bike is equipped with a twist shifter located on the left side of your handlebar.

Twisting the shifter forward will move your  derailleur to the left causing your drivetrain to switch to a larger gear. The larger gear will give your bike more torque and less speed.
When climbing hills always shift to a larger sprocket to give your bike more torque.
Twisting the shifter back will move your derailleur to the right causing your drivetrain to switch to a smaller gear. The smaller gear will give your bike more speed and less torque.
Only shift one gear at a time. Shifting several gears at once will move the derailleur faster than the chain, causing damage to drivetrain system.
For more information about shifting, please review your SRAM manual in your owner’s packet.

Section 5 – Operating Instructions

Operation of control buttons

Operation of control buttons

Press and hold the power button located on the left side of the handle bar to turn on your bike.

Your bike comes with 5 levels of power or pedal assist.
Levels 1-5 can be used with either thumb throttle or pedal assist.
Level 1 is 20% motor power, Level 2 is 40% motor power, Level 3 is 60% motor power, Level 4 is 80% motor power, and Level 5 is 100% motor power.
Level 0 uses no motor power, it is used as a safety feature or for pedaling the bike under the rider’s own power with no assist.
For more information on your LCD display review the manual in your owners packet.

How to use Thumb Throttle
When riding your Rambo Bike, the thumb throttle can be used from a complete stop if you choose.
The rider must select the appropriate pedal assist level according to rider skill and terrain. Then by pushing down on the throttle the motor will engage and the bike will begin to move forward. The pedal assist level can be changed while the bike is in motion. As the power level from the motor is increased, the bike will react with more speed and power. When coming to a stop, after the MPH has reached 0.0, the rider will have 6 seconds to use the same pedal assist level to take off again on the bike.
After 6 seconds, the pedal assist level will return to 0. To use motor power again, press the+ button until the desired pedal assist level has been reached.

How to use Pedal Assist
When riding your Rambo Bike, the pedal assist can also be used from a complete stop if you choose.
The rider must select the appropriate pedal assist level according to rider skill and terrain. Then the rider can begin to pedal, and after 1 or 2 revolutions on the pedals (depending on speed) the motor will engage and assist the rider in propelling the bike. The pedal assist level can be changed while the bike is in motion. As the power from the motor is increased the bike will react with more speed and power.
When coming to a stop, after the MPH has reached 0.0 the rider will have 6 seconds to use the same pedal assist level to take off on the bike. After 6 seconds, the pedal assist level will return to 0. To use motor power again, press the + button until the desired pedal assist level has been reached.

Added Features of your Bike
Brakes: Rambo uses E-bike specific brakes on all their bikes. This means that when the brakes are applied the motor can not run. This allows for safe braking and stopping.
Shift Sensor: Rambo uses an electronic shifting sensor to kill the motor briefly while you are shifting gears. This ensures a smooth shift and less wear and tear on your drivetrain.
Ergonomic handlebar controls: Rambo has configured the absolute best handlebar configuration for e-bikes. This ensures all operations can be done with ease. Shifter, thumb throttle, brakes, etc.

Product repairs and/or updates not covered by warranty will be provided at a set rate. At its sole discretion, Rambo will determine whether the component will be covered under this warranty. This warranty is in lieu of all other warranties expressed or implied. You may have certain legal rights that extend beyond this warranty in certain states.

This limited warranty does not cover installation, disassembly, adjustments of components, normal wear and tear, damage caused by improperly installed parts or components, installation and use of aftermarket accessories or storage fees.
