SAFETY WARNINGS

WARNING: Riding an electric motorbike does present potential risks and caution is required. Like any riding product, an electric motorbike has inherent hazards associated with its use (for example, falling off or riding it into a hazardous situation). Like any riding product, electric motorbikes can and are intended to move and it is, therefore, of course, possible to lose control or otherwise get into dangerous situations. Both children, and adults responsible for supervising them, must recognize that if such things occur, a rider can be seriously injured or die even when using safety equipment and other precautions. RIDE AT YOUR OWN RISK AND USE COMMON SENSE.

WARNING: PARENTAL AND ADULT RESPONSIBILITY AND SUPERVISION NECESSARY: This manual contains important safety information. It is your responsibility to review this information and make sure that all riders understand all warnings, cautions, instructions, and safety topics, and assure that young riders are able to safely and responsibly use these products. Razor recommends that you periodically review and reinforce the information in this manual with younger riders and that you inspect and maintain your children’s products to ensure their safety.

WARNING: THE SX500/MX500 IS NOT FOR CHILDREN UNDER AGE 14 OR HEAVIER THAN 175 LB (79 KG). THE MX650 IS NOT FOR CHILDREN UNDER AGE 16 OR  HEAVIER THAN 220 LB (100 KG). Because products, like electric motorbikes, can and do present potential hazards plainly associated with their use, it is well recognized THE NEED FOR  EXERCISE OF PARENTAL RESPONSIBILITY IN SELECTING RIDING PRODUCTS APPROPRIATE TO THE AGE OF A CHILD, OR PARENTAL SUPERVISION IN SITUATIONS IN  WHICH CHILDREN OF VARIOUS AGES MAY HAVE ACCESS TO THE SAME RIDING PRODUCTS, IS IMPORTANT. Not every product is appropriate for every age or size of the child, and different age recommendations are found within this category of product which is intended to reflect the nature of the hazards and the expected mental or physical ability, or both, of a rider to cope with the hazards.

Razor recommends that children under the age of 14 not be permitted to use the SX500/MX500 and that children under the age of 16 not be permitted to use the MX650. This recommendation is based not just on age or weight or height – it reflects consideration of expected maturity and skills as well as physical size. The recommended rider age of 14 years or older for SX500/ MX500 and rider age of 16 years or older for MX650 are only estimates and can be affected by the rider’s size, weight or skills – not every child 14 years old will be suited to the SX500/MX500 and not every child 16  years old will be suited to the MX650. Certainly, any rider unable to fit comfortably on the SX500/MX500/MX650 should not attempt to ride it, but a parent’s decision to allow his or her child to ride these products should be based on the child’s maturity, skill, and ability to follow rules. Razor emphasizes that adults are strongly advised not to disregard Razor’s recommendations or permit younger children to ride the SX500/MX500/MX650.

DO NOT EXCEED THE WEIGHT LIMIT OF 175 lb (79 kg) for SX500/MX500 and 220 lb (100 kg) for MX650. Rider weight alone also does not necessarily mean a person’s size is appropriate to fit or maintain control of the SX500/MX500/MX650. Keep these products away from small children and remember that these products are intended for use only by persons who are, at a minimum,  completely comfortable and competent while operating these products.

Persons with any mental or physical conditions that may make them susceptible to injury, impair their physical dexterity or mental capabilities to recognize, understand, and follow safety instructions and to be able to understand the hazards inherent in a product’s use, should not use or be permitted to use products inappropriate for their abilities. Persons with heart conditions, head, back, or neck ailments (or prior surgeries to these areas of the body), or pregnant women, should be cautioned not to operate these products.

CHECK AND MAINTAIN MOTORBIKE CONDITIONS
Before use, check to confirm that any and all chain guards or other covers and guards are in place and in serviceable condition. Check that the brakes are functioning properly and that tires are inflated properly, and have sufficient tread remaining. The motorbike should be maintained and repaired in accordance with the manufacturer’s specifications, using only the manufacturer’s authorized replacement parts, and should not be modified from the manufacturer’s original design and configuration.

ACCEPTABLE RIDING PRACTICES AND CONDITIONS
Always check and obey any local laws or regulations, which may affect the locations where the electric motorbike may be used. Keep safely away from cars and motor vehicle traffic at all times, and only use where allowed and with caution.
Do not activate the speed control on the handgrip unless you are on the motorbike and in a safe, outdoor environment suitable for riding.
The normal powered top speed of these motorbikes will be approximately 15 mph (24 km/h) for SX500/MX500 and 17 mph (27 km/h) for MX650, which can be affected by conditions, such as rider weight, inclines, tire inflation, and battery charge level. Avoid excessive speeds that can be associated with downhill rides.
Maintain a hold on the handlebars at all times. Do not touch the brakes or motor on your motorbike when in use or immediately after riding, as these parts can become very hot.
Ride defensively. Watch out for potential obstacles that could catch your wheel or force you to swerve suddenly or lose control. Be careful to avoid pedestrians, skaters, skateboards, scooters, bikes,  children, or animals who may enter your path, and respect the rights and property of others.
These electric motorbikes are intended for use on flat, dry surfaces, such as pavement or level ground, without loose debris, such as sand, leaves, rocks or gravel. Wet, slick, bumpy, uneven or rough surfaces may impair traction and contribute to possible accidents. Do not ride your motorbike in mud, ice, puddles or water. Watch out for potential obstacles that could catch your wheel or force you to swerve suddenly or lose control. Avoid sharp bumps, drainage grates, and sudden surface changes.
Do not attempt or do stunts or tricks on your electric motorbike. These motorbikes are not made to withstand abuse from misuse, such as jumping, curb grinding or any other type of stunts. Racing,  stunt riding, or other maneuvers also enhance the risk of loss of control or may cause uncontrolled rider actions or reactions.

Never allow more than one person at a time to ride the motorbike.
Do not ride at night or when visibility is limited.
Never use near steps or swimming pools.
Do not allow hands, feet, hair, body parts, clothing, or similar articles to come in contact with moving parts, wheels, or drive train chains while the motor is running.
Never use headphones, a cell phone or text when riding.
Never hitch a ride with a vehicle.
Do not ride your motorbike in wet or icy weather and never immerse the motorbike in water, as the electrical and drive components could be damaged by water or create other possibly unsafe conditions. Never risk damaging surfaces, such as carpet or flooring, by use of an electric motorbike indoors.

PROPER RIDING ATTIRE
Always wear proper protective equipment, such as an approved safety helmet (with chin strap securely buckled), elbow pads, and kneepads.
A helmet may be legally required by local law or regulation in your area.
A long-sleeved shirt, long pants, and gloves are recommended. Always wear athletic shoes (lace-up shoes with rubber soles) and keep shoelaces tied and out of the way of the wheels, motor, and drive system. Never ride barefooted or in sandals.

USING THE CHARGER
The charger supplied with the electric motorbike should be regularly examined for damage to the cord, plug, enclosure, and other parts. In the event of such damage, the motorbike must not be charged until the charger has been repaired or replaced.
Use only with the recommended charger.
Use caution when charging.
The charger is not a toy. The charger should be operated by an adult.
Do not operate chargers near flammable materials.
Unplug the charger and disconnect from the motorbike when not in use.
Always disconnect from the charger prior to wiping down and cleaning your motorbike with a damp cloth.

FAILURE TO USE COMMON SENSE AND HEED THE ABOVE WARNINGS INCREASES THE RISK OF SERIOUS INJURY. USE WITH APPROPRIATE CAUTION AND SERIOUS  ATTENTION TO SAFE OPERATION.

Inflating the Tires
Tires are inflated when shipped, but they invariably may lose some pressure between the point of manufacturing and your purchase. Always inflate tires to the correct PSI before first-time use.
Lower air pressure can result in a shorter ride time. Periodically check tires. Reinflate when needed.

1. Using a bicycle-style tire pump equipped with a Schrader-type valve, inflate the tires to the correct PSI indicated on the sidewall of the tires.

WARNING: Failing to properly adjust and tighten the nuts and bolts that affix the fork can cause you to lose control and fall.
WARNING: Do not use the electric motorbike for the first time until you have inflated the tires to the correct PSI. Failure to do so may damage your electric motorbike and void your warranty.
WARNING: Do not overinflate, as this could damage the tire or wheel.
Note: The pressurized air supplies found at gasoline stations are designed to inflate high-volume automobile tires. If you decide to use such an air supply to inflate your motorbike tires, first make sure the pressure gauge is working, then use very short bursts to inflate to the correct PSI. If you inadvertently over-inflate the tire, release the excess pressure immediately.

CHARGING THE BATTERY

Your electric motorbike may not have a fully charged battery; therefore you must charge the battery prior to use.

• Initial charge time: 12 hours.

• Recharge time: up to 12 hours, even if the light turns green. Recommended maximum charging time is 24 hours.

• Always charge the battery immediately after riding.

• Fully charge the battery before storing for extended periods of time.

• Unplug the charger from the wall outlet when not in use.

• Failure to recharge the battery periodically may result in a battery that will not accept a charge.

any repair or maintenance

Adjusting the Brakes
Required Tools: 5 mm Allen Wrench (included)

The brake lever is fitted with a cable adjuster to compensate for cable stretch and/or to fine-tune the lever movement to brake engagement.

1. To adjust brake cable play, thread the brake lever adjuster in or out 1/4 to 1/2 turn until the desired brake adjustment is attained. Most adjustments are complete at this step. If the brake still needs further adjustment, proceed to step 2.

2. If the brake has too much slack, loosen the rear anchor bolt with a 5 mm Allen wrench and pull the brake wire tighter. The distance of the brake wire between the end of the cable and the anchor bolt should be between 37 mm and 44 mm.

3. If the brake rotor is dragging on the brake pads, use your fingers to twist the caliper adjuster in either direction until the rotor is centered between pads.

WARNING: The brakes are capable of causing the electric motorbike to skid the tire throwing an unsuspecting rider. Practice in an open area free from obstacles until you are familiar with the brake function. Avoid skidding to a stop as this can cause you to lose control or damage the tires.

Testing the Brakes. To use the brakes, squeeze the brake levers to increase the pressure on the brakes. The brake levers are fitted with a cable adjuster to compensate for cable stretch and/or to fine-tune the lever movement to brake engagement. If brakes are not engaging properly, follow instructions for adjusting the brakes.
Note: The brake levers contain safety switches to cut power to the motor when the brakes are applied. In an emergency, applying the brakes will always stop the product from moving. Do not disable or replace these brake levers with anything other than genuine Razor replacement parts.

Spoke Tension
Required Tool: Spoke tightener (included)

1. Verify the spoke tension by shaking each spoke with your fingers. Spoke should not be loose from hub. Look for any play between where the spoke flanges attach to the hub. Try to turn the nipple using your fingers. You should not be able to spin any nipple by hand. If one or more spokes is loose, all spokes must be checked and need to be tightened with a spoke tightener.
   

2. Start with the spoke closest to the tire valve stem and tighten each nipple, in sequence, exactly 1/4 to 1/2 turn. A single 1/4 to 1/2 turn may not be enough to bring the spokes into proper tension.  Continue tightening all spokes, no more than 1/2 turn, in sequence until all spokes are tight.
   Note: More than a 1/2 turn each can cause the wheel to become distorted and wobbly, thus permanently damaging the wheel.

Chain and Sprocket
Proper chain alignment must be maintained. The wheel must not be skewed. If the chain is noisy or running rough, check the lubrication, tension, and alignment of the sprockets, in that order.
