Product I.D. Code: _________________________

Safety Warnings

WARNING: Riding an electric motor bike presents potential risks and requires caution. Like any riding product, it has inherent hazards such as falling off or riding into hazardous situations. Electric motor bikes are intended to move, and loss of control or dangerous situations can occur. Both children and supervising adults must recognize that serious injury or death can result, even with safety equipment. 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 ensure all riders understand warnings, cautions, instructions, and safety topics. Ensure young riders can safely and responsibly use these products. Razor recommends periodically reviewing and reinforcing this manual's information with younger riders, and inspecting and maintaining the product for 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). Selecting appropriate riding products for a child's age and providing supervision are crucial due to the potential hazards. Age recommendations reflect hazards and a rider's mental or physical ability to cope. Razor recommends children under 14 not use SX500/MX500, and under 16 not use MX650. These are estimates based on maturity, skills, and size. Any rider unable to fit comfortably should not attempt to ride. Parental decisions should be based on the child's maturity, skill, and ability to follow rules. Adults are strongly advised not to disregard Razor's recommendations or permit younger children to ride.

Persons with mental or physical conditions that may affect their ability to safely operate the product, understand instructions, or recognize hazards should not use these products. Individuals with heart conditions, head, back, or neck ailments, or pregnant women, should be cautioned against operating these products.

CHECK AND MAINTAIN MOTOR BIKE CONDITIONS

Before use, ensure all chain guards, covers, and guards are in place and serviceable. Check that brakes function properly and tires are inflated with sufficient tread. Maintain and repair the motor bike according to manufacturer specifications, using only authorized replacement parts, and do not modify its original design.

ACCEPTABLE RIDING PRACTICES AND CONDITIONS

Always check and obey local laws and regulations regarding where the electric motor bike may be used. Keep safely away from cars and motor vehicle traffic at all times. Use only where allowed and with caution.

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

The normal powered top speed is approximately 15 mph (24 km/h) for SX500/MX500 and 17 mph (27 km/h) for MX650. This can be affected by rider weight, inclines, tire inflation, and battery charge. Avoid excessive speeds, especially on downhill rides.

Maintain a hold on the handlebars at all times. Do not touch the brakes or motor immediately after riding, as these parts can become very hot.

Ride defensively. Watch for potential obstacles that could cause loss of control. Be careful to avoid pedestrians, skaters, skateboards, scooters, bikes, children, or animals. Respect the rights and property of others.

These electric motor bikes are intended for use on flat, dry surfaces like pavement or level ground, without loose debris (sand, leaves, rocks, gravel). Wet, slick, bumpy, uneven, or rough surfaces can impair traction and contribute to accidents. Do not ride in mud, ice, puddles, or water. Avoid sharp bumps, drainage grates, and sudden surface changes.

Do not attempt stunts or tricks. These motor bikes are not designed to withstand abuse like jumping, curb grinding, or other stunts. Racing, stunt riding, or other maneuvers increase the risk of loss of control.

Safety Warnings (Continued)

  • Never allow more than one person at a time to ride the motor bike.
  • 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 chain 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 motor bike in wet or icy weather and never immerse the motor bike in water, as electrical and drive components could be damaged or create unsafe conditions. Never risk damaging surfaces like carpet or flooring by using an electric motor bike 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. 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 wheels, motor, and drive system. Never ride barefooted or in sandals.

USING THE CHARGER

The charger supplied should be regularly examined for damage to the cord, plug, enclosure, and other parts. If damaged, the motor bike must not be charged until the charger is repaired or replaced.

  • Use only with the recommended charger.
  • Use caution when charging.
  • The charger is not a toy. It should be operated by an adult.
  • Do not operate the charger near flammable materials.
  • Unplug the charger and disconnect from the motor bike when not in use.
  • Always disconnect from the charger prior to wiping down and cleaning your motor bike with a damp cloth.

Chargers have built-in overcharge protection. If the charger gets warm during regular use, this is normal. If it does not get warm, it does not mean it is not working properly.

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

Pre-Ride Checklist

  • Brakes: Check for proper function. Squeeze brake levers; brakes should provide positive braking action. Ensure brakes are not rubbing when levers are released.
  • Tires: Periodically inspect tires for excess wear and replace as needed. Regularly check tire pressure and inflate as needed. If you get a flat tire, the inner tube can be patched or a new tube purchased from Razor or an authorized repair center.
  • Frame, Fork and Handlebars: Check for cracks or broken connections. Inspect regularly.
  • Hardware/Loose Parts: Before every ride, check all parts (nuts, bolts, cables, fasteners) to ensure they are secure and assembled correctly. There should not be any unusual rattles or sounds from loose parts or broken components. If the unit is damaged, do not ride. Reference "Safety Warnings" on pages 1 and 2.
  • Safety Gear: Always wear proper protective gear, such as an approved safety helmet (with chin strap securely buckled), elbow pads, and kneepads. Always wear athletic shoes (lace-up shoes with rubber soles) and keep shoelaces tied and out of the way of wheels, motor, and drive system. NEVER RIDE BAREFOOTED OR IN SANDALS.
  • Laws and Regulations: Always check and obey any local laws or regulations.
  • Insurance: Do not assume existing insurance policies cover motor bike use. Check with your insurance company for information.
  • Storage: Prolonged exposure to UV rays, rain, and elements may damage enclosure materials; store indoors when not in use.

Usage

Starting the Electric Product

Put kickstand up. Sit on the electric motor bike seat with both feet on the ground on either side for balance. Place both hands on the handlebars. Slowly push forward with one foot and apply the throttle (A).

Note: Keep both feet on the foot pegs when the unit is in motion.

Stopping the Electric Product

Release the throttle (A) and apply the brakes by squeezing the brake levers (B & C).

Note: When coming to a complete stop, place both feet on the ground to balance the unit.

Repair and Maintenance

Turn power switch "OFF" before beginning repair or maintenance:

  • Read the instructions.
  • Secure the unit under repair.
  • Remove charger plug.
  • Turn the power switch off.
  • Exercise caution around exposed parts.
  • Contact Razor customer service if unsure about any repair or maintenance.

Adjusting the Brakes

Required Tool: 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 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 motor bike 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: Squeeze the brake levers to increase pressure. The brake levers have a cable adjuster for fine-tuning. If brakes are not engaging properly, follow adjustment instructions.

Note: The brake levers contain safety switches to cut power to the motor when brakes are applied. In an emergency, applying the brakes will always stop the product. Do not disable or replace these brake levers with anything other than genuine Razor replacement parts.
