safeTy warnIngs

WARNING: Riding an electric motorbike can be a hazardous activity.

Certain conditions may cause the equipment to fail without fault of the manufacturer. Like other electric products, the Dirt Rocket can and is intended to move, and it is therefore possible to lose control, fall off and/or get into dangerous situations that no amount of care, instruction or expertise can eliminate. If such things occur you can be seriously injured or die, even when using safety equipment and other precautions. RIDE AT YOUR OWN RISK AND

USE COMMON SENSE.

This manual contains many warnings and cautions concerning the consequences of failing to maintain, inspect or properly use your electric motorbike. Because any incident can result in serious injury or even death, we do not repeat the warning of possible serious injury or death each time such a possibility is mentioned.

APPROPRIATE RIDER USE AND PARENTAL SUPERVISION

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 this product. Razor USA recommends that you periodically review and reinforce the information in this manual with younger riders, and that you inspect and maintain your children’s product to insure their safety.

The recommended rider age of 13 years (MX350/MX400) is only an estimate, and can be affected by the rider’s size, weight or skills. Any rider unable to fit comfortably on the Dirt Rocket should not attempt to ride it. A parent’s decision to allow his or her child to ride this product should be based on the child’s maturity, skill and ability to follow rules.

Keep this product away from small children and remember that this product is intended for use only by persons who are, at a minimum, completely comfortable and competent while operating the products.

Do not exceed 140lbs. (63kgs.) total weight on the MX350 and MX400. Rider weight does not necessarily mean a person’s size is appropriate to fit or maintain control of the Dirt Rocket.

Do not touch the brakes or electric motor on your electric motor bike when in use as they can become very hot.

Refer to the section on safety for additional warnings.

ACCEPTABLE RIDING PRACTICES AND CONDITIONS

Always check and obey any local laws or regulations which may

affect the locations where the Dirt Rocket may be used.

Ride defensively. Watch out for potential objects 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.

The Dirt Rocket is meant to be used only in controlled environments free of potential traffic hazards and not on public streets or sidewalks. Do not ride your electric motor bike in any areas where pedestrian or product traffic is present.

Do not activate the speed control on the hand grip unless you are on the electric motor bike and in a safe, outdoor environment suitable for riding.

These bikes were manufactured for performance and durability but are not impervious to damage. Jumping or other aggressive riding can over-stress and damage any product, including the electric motorbike, and the rider assumes all risks associated with high-stress activity.

Be careful and know your limitations. Risk of injury increases as the degree of riding difficulty increases. The rider assumes all risk associated with aggressive riding activities.

Maintain a hold on the handlebars at all times.

Never carry passengers or allow more than one person at a time to ride the electric motor bike.

Never use near steps or swimming pools.

Keep your fingers and other body parts away from the drive chain, steering system, wheels and all other moving components.

Never use headphones or a cell phone when riding.

Never hitch a ride with another vehicle.

Do not ride the Dirt Rocket in wet or icy weather and never immerse the electric motor bike in water, as the electrical and drive components could be damaged by water or create other possibly unsafe conditions.

The Dirt Rocket is intended for use on flat, level ground without loose debris such as rocks or gravel. Wet, slick, bumpy, uneven or rough surfaces may impair traction and contribute to possible accidents. Do not ride the electric motorbike in mud, ice, puddles or water. Avoid excessive speeds that can be associated with downhill rides. Never risk damaging surfaces such as carpet or flooring by use of an electric motor bike indoors.

Do not ride at night or when visibility is limited.

PROPER RIDING ATTIRE

Always wear proper protective equipment such as an approved safety helmet

(with chin strap securely buckled). A helmet may be legally required by local law or regulation in your area. Elbow pads and kneepads, a long-sleeved shirt, long pants and gloves are recommended. Always wear athletic shoes (lace-up shoes with rubber soles), never ride barefooted or in sandals, and keep shoelaces tied and out of the way of the wheels, motor and drive system.

USING THE CHARGER

The charger supplied with the electric motor bike should be regularly examined for damage to the cord, plug, enclosure and other parts, and in the event of such damage, the bike 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. Charger should be operated by an adult.

Do not operate charger near flammable materials.

Unplug charger and disconnect from bike when not in use.

Always disconnect from the charger prior to wiping down and cleaning your scooter with liquid.

Inflating the Tires

Tires are inflated when shipped, but they invariably lose some pressure between the point of manufacturing and your purchase.

Using a bicycle tire pump equipped for a Schrader valve, inflate both tires to the PSI indicated on the sidewall of the tire.

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 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; you must charge the battery prior to use.

• Initial charge time: 12 hours

• Recharge time: up to 12 hours,

depending on level of depletion.

• Fully charge battery before storing.

• When the motorbike is not in regular use,

recharge the battery at least once a

month until normal use is resumed.

• Run time: Up to 30 minutes of continuous ride time.

Run time may vary depending on riding conditions,

climate and/or proper maintenance.

• Average battery life: 250 charge/discharge cycles

• To ensure long battery life, do not store the battery

in temperatures above 75° or below -10° F.

Charger

Note: Make sure power is turned OFF when unit is not in use. If the power switch is left on for an extended period of time, the battery may reach a stage at which it will no longer hold a charge.

1

Plug the charger into a wall outlet. If the lights on charger do not light up, check the power to the outlet. If necessary, try a different outlet.

2

Turn power OFF before charging. Plug the charger into the charger port to charge unit.

warnIng:

Rechargeable batteries are only to be charged under adult supervision. Always disconnect your electric motorbike from the charger before cleaning with liquid.

Note: If your charger does not look like the one illustrated, your unit has been supplied with an alternative charger.

The specifications and charging procedure would not change.

The charger has a small window with one LED to indicate the charge status. Refer to the illustration on the charger unit for the actual “charging” and

“charged” status indications for your model charger.

Chargers have built-in overcharge protection to prevent battery from being overcharged.

Charger will get warm during use. This is normal for some chargers and is no cause for concern. If your charger does not get warm during use, it does not mean that it is not working properly.

warnIng: Failure to recharge the battery at least once a month may result in a battery that will no longer hold a charge.

q

adjusting the Brakes

Tools required: 10mm open wrench

1

To adjust the tension, 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 brake still needs further adjustment, proceed to step 2.

2

If the brake has too much slack, use a 10mm open wrench to loosen the brake anchor cable for additional adjustment. q

Testing the Brakes

To use the brake, squeeze the lever to increase the pressure on the brake. 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. If brake is not engaging properly, follow instructions for adjusting the brakes outlined below.

warnIng:

The brake is 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 rear tire.

q

chain and sprocket

The chain will typically have a “loose spot” and “tight spot” corresponding with a particular sprocket rotational position. This is normal and common to all chain-driven products due to run-out tolerances of the freewheel and sprocket. The chain should be adjusted to the ideal tension with chain in the tightest spot.

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

q

Battery care and Disposal

Do not store the battery in temperatures above 75° F or below -10° F.
