REPAIR AND MAINTENANCE

11

WARNING: 

The brake is 

capable of skidding the rear tire 

and 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 and/or damage the rear tire.

Turn power button “OFF” before beginning repair or maintenance:

• Read the instructions
• Remove charger plug
• Turn the power off

• Secure the product under repair
• Exercise caution around  

exposed parts

• Contact Razor customer service 

if unsure about any repair or 

maintenance

• Repair and maintenance should  

be performed by an adult only

 Adjusting the Brake

Required Tool:

 5 mm Allen Wrench (included)

1

 To adjust the brake cable 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, 

loosen the rear anchor bolt with a 5 

mm Allen wrench and pull the brake 

cable tight. The distance of the 

brake wire between the end of the 

cable and the anchor bolt should be 

between 37 mm and 44 mm.
