Required Tools

WARNING: DO NOT USE NON-RAZOR PRODUCTS WITH YOUR RAZOR ELECTRIC MOTORBIKE. The motorbike has been built to certain Razor design specifications. The original equipment supplied at the time of sale was selected on the basis of its compatibility with the frame, fork and all other parts. Certain aftermarket products may not be compatible and will void the warranty.

Place the handlebars in the handlebar clamps with tools and manual. Note: Handlebar clamps are located in the plastic bag.
Align parallel to the fork and tighten the bolts using a 6 mm Allen wrench. When properly tightened, the handlebars should not move forward or backward.
Adjust the brake lever adjuster to the proper place and tighten it with the 5 mm Allen wrench.

Attaching the Front Fender

Align the fender with the hole in the fork and insert the bolt. Tighten securely using a 10 mm wrench and 5 mm Allen wrench.

Attaching the Number Plate

Remove screw from front fork. Align the number plate with the hole in the fork and tighten with a Phillips screwdriver.

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-style tire pump equipped for a Schrader-type valve, inflate the front tire to the PSI indicated on the sidewall of the tire.
Testing the Brakes
To use the brakes, squeeze the levers to increase the pressure on the brake. 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 outlined below.
Charging the Battery
Your electric motorbike may not have a fully charged battery; therefore it is a good idea to charge the battery prior to use.
Initial charge time: 18 hours
Recharge time: up to 12 hours, depending on the level of charge Up to 40 minutes of continuous ride time
Average battery life: 250 charge/discharge cycles
1. Turn OFF power switch before charging. Plug charger into the charger port on the electric motor bike.
2. Plug the charger plug into a wall outlet. If the lights on the charger do not light up, check the power to the outlet. If nec-essary, try a different outlet.

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.
WARNING: 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 or two LEDs 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 over-charge protection to prevent battery from being over-charged. 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. Be sure to properly align the groove on the charger input plug with the corresponding socket on the case; otherwise, no charging action will occur.

Installing the Front Wheel

Position wheel in front fork and slide disk brake into caliper.
Slide axle through fork, spacer and wheel hub. When axle passes through the other side of the wheel hub, add the other spacer and slide though the fork. Secure with washer and nut.
Note: Front axle is installed with the spacer between the fork and wheel for all Dirt Rockets.
Note: If your model has one short spacer, it goes on the side of the hub with the disc brake.
With a 14mm and 17mm wrench tighten the front wheel screws.

WARNING: Failing to properly adjust and tighten the nuts and bolts that affix the forks can cause you to lose control and fall.

Setup Guide of Razor Dirt Rocket MX650

Setting up the Razor is easy and straightforward. Here are the steps to follow:

Charge the battery fully before the first use.
Adjust the seat height to fit the rider's size and comfort.
Check the tire pressure and adjust it if necessary.
Turn on the power switch and test the brakes and throttle control.
Familiarize yourself with the control panel and the hand-operated brakes and throttle.
Start the bike by twisting the throttle control and enjoy your ride.

REPAIR AND MAINTENANCE

Check the Razor web site for any updates on the latest repair and maintenance procedures. Turn power switch “OFF” before conducting any maintenance procedures.

Adjusting the Brakes

Tools required: 5mm L-wrench

To adjust the 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 for rear brake.
If the brake has too much slack, loosen the rear anchor bolt with a 5mm L-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 37mm and 44 mm.
If the brake rotor is dragging on the brake pads, use your fingers to twist the caliper adjuster in either direction until rotor is cen-tered between pads.

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.

Chain and Tire Replacement

Tools required: Phillips screwdriver and two (2) 19mm wrenches.

Loosen screw and remove chain guard.
Using two 19mm wrenches, loosen both axle nuts.
Push the chain tensioner down to loosen the chain and remove the chain from the wheel sprocket and motor sprocket. Push and remove the wheel downward.
Note: Your hands will get greasy doing this.
Install the new chain or wheel by slipping the chain around the axle. Slide the axle into the slots on the frame. Slide the chain tensioner down and maneuver the chain onto the rear sprocket and front sprocket.
Re-attach the chain guard. Test ride and check. Readjust as needed.

Note: the arrangement of the hardware sequence:

Right Side (Throttle)
Nut
Washer
Spacer
Left Side (Brake)
Nut
Washer
Spacer

Replacing the Fuse

Remove the seat fairing to lo-cate the 3 fuse boxes attached to the batteries.
Check all 3 fuses to see if the fuse(s) have burnt out. If the fuse(s) is(are) damaged, open the fuse cover.
Remove any fuse that is damaged or burnt out and replace with a new one of equal amperage.
Note: Amperage is located on top of fuse.
WARNING: To prevent shock, please follow the instructions accordingly and do not skip any steps.
Close the fuse cover and reattach the seat fairing.

Checking Spoke Tension

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 us-ing 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 wrench.
Start with 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.

WARNING: Regularly check the spoke tension and retighten the spokes whenever loose. If you have any doubt, ask an experienced motorcycle or bicycle mechanic to inspect your spokes to determine if the spokes need tightening or adjusting.

SAFETY WARNINGS
