time of sale were selected on the basis of their compatibility with the frame, fork and all other parts. Certain after-market products may or may not be compatible with your Razor Electric Scream Machine. Consult your retailer or call Razor prior to modifying or replacing any component with a non-factory specified product. TOOLS REQUIRED FOR ASSEMBLY ONLY 4, 5 and 6 mm hex (Allen) keys Razor recommends assembly by an adult with experience in bicycle mechanics.
2. Proper Fit and Size Adjustments 2. Fit. When properly adjusted, the rider should be able to pedal comfortably and steer with both feet remaining on the pedals at all times. If the rider has to stretch to reach the pedals or is too cramped, the seat should be adjusted fore or aft accordingly. WARNING: The age recommendation is only an estimate. If you are too small or too large to comfortably reach the pedals or handlebars, do not ride the Electric Scream Machine.
WARNING: Cable operated brakes are very effective but must be adjusted and maintained on a regular basis. Check or have them checked and adjusted by a qualified mechanic. Worn brake parts, stretched or frayed inner wires or a kinked housing indicate brake service or parts replacement may be necessary for proper function. 4. Safety 4A. Helmets.
components. Riders with longer hair may risk entanglement in the rear wheels or drive system. Do not allow long hair to get near the wheels or drive system. 5. Safety Check (before each ride) 5A. Loose parts. While straddling the Electric Scream Machine, lift the front wheel off the ground two or three inches and let go so it can bounce on the ground. Does everything sound tight? There should not be any unusual rattles or sounds from loose parts or broken components.
be different than the color of the product you purchased. The colors were altered to make the assembly photos easier to follow. WARNING: Razor highly recommends that you have your Electric Scream Machine assembled by an experienced, adult mechanic. Many retailers provide assembly but some charge extra. If your retailer can’t do the assembly, you can have your Electric Scream Machine assembled at a bicycle shop for a fee.
not tangled or twisted and so the brake cable and trigger wire are routed as shown in 2c. Insert the handlebar and upper fork crown assembly into the fork legs as shown in Figure 2d. Press both the spring buttons (arrows, 2d) and continue to slide the handlebar assembly into the fork until the spring buttons engage the holes (A) as shown in Figure 2e, and the steering tube extends through the upper fork crown (B). The fork stop must be positioned in the slot in the upper crown.
Figure 2f. Figure 2g. Once the fork crown is firmly seated, loosen the adjusting screw approximately 1/4 to 1/2 turn. This relaxes the preloading and allows the steering to rotate without binding. Test by turning the handlebars to full lock left and right. It should steer with slight friction and no binding or tight spots. NOTE: The steering bushings are designed for long life and should require no maintenance. They do not require oil or any type of “wet” lubrication.
Figure 3a. The wheel on the right is the wheel with the power coupler. Notice the blue residue on the axle threads. This is a non-hardening thread-locking “glue” designed to prevent the axle from vibrating loose. You will install the wheel with the power coupler on to the drive-side of the Electric Scream Machine. The coupler is shown in Figure 3b. Figure 3b. The power coupler.
left-side (non-drive) wheel. NOTE: The left side (non-drive) axle and locking nuts have backwards threading. This axle is special and is not compatible with the drive-side of the Electric Scream Machine. This axle is also not compatible with previous versions of the Scream Machine. Using a 6mm Allen key, carefully thread the axle into the frame by turning counter clockwise as shown in Figure 3e. Figure 3e. Tightening the backwards threaded axle.
Figure 3f. Tightening the locknuts against the frame as shown in figure 3f. Repeat the adjustment procedure in 6C as many time as necessary to obtain the proper adjustment. Check www.razor.com for tech updates or video clips on this and other procedures. NOTE: Although we make every effort to keep our manual up-todate, if your Electric Scream Machine does not look like this, then we’ve made product improvements since this document was printed.

Figure 5a. Figure 5b. 6F. Install cranks and pedals. The crankarms, pedals and hardware are supplied in the parts bag and must be installed. The crank marked L goes on the left side and the crank marked R goes on the right side (when sitting in the seat). Figure 6a. Assemble as shown in the sequence below. Tighten securely. Figure 6b. Figure 6c. 13 Figure 6d.
6F. Charging prior to use. The Electric Scream Machine will probably not have a fully charged battery pack at the time of purchase. Therefore it is a good idea to charge the battery prior to use. The charging input is located at the back of the motor cover next to the switch. The charger has two small LEDs that illuminate to indicate the charge status. Red indicates the charger is working and green indicates the battery is fully charged.
Figure 8a. If there is too much slack, the lever will go all the way to the handlebar without the brake being applied. If there is not enough slack, the brake will drag even when the lever is not pulled. Ideally, you want 2-3mm of play in the lever before the brake engages (as shown in figure 8b). Figure 8b. To adjust, loosen the lock ring and turn the barrel 1/4 to 1/2 turn to loose or tighten as required and squeeze the brakes to test. Continue to adjust until the proper cable slack is attained.
Figure 8c. NOTE: The brake system requires a break-in period. You may have to repeat procedure 6F often during the first several hours of use. Repeat as necessary thereafter to maintain proper brake function. The Electric Scream Machine is supplied with a brake lever that adjusts to accommodate a variety of hand sizes. To adjust the brake lever so it is easier for shorter hands to operate the brake, turn the screw in the direction marked “B” in the photo below.
the responsibility of the user to periodically inspect the brake pads for excess wear and misalignment. If you do not understand how to adjust or realign the brake pads, we strongly recommend you seek the help of a qualified mechanic. If the brakes are not properly adjusted the brakes may fail and you can be seriously injured. 8.
8D. Turning without warning. Children are often struck from behind because they made unexpected turns into traffic, or they inadvertently veered into traffic when looking over their shoulder. Observe the following safety tips for left turns: Do not cut across the street, cross only at intersections. Practice looking over your shoulder to the rear without accidentally turning (do this only in an open space free from traffic and obstructions). 8E. Riding at night and in low visibility.
fail without fault of the manufacturer. Activities involving the use of bicycles carry the risk of injury or death. 9.
