Scooter Rear Wheel or Engine Belt Falls Off

Problem Analysis and Solutions

Rear Wheel or Engine Belt Falls Off
If the drive belt falls off the motor or rear wheel but remains on the scooter, the belt is typically misaligned.
Use two wrenches to loosen and tighten the axle nut to avoid damaging the axle hardware.
  1. Loosen the hardware that connects the brake to the scooter frame.
  2. Slightly loosen the rear axle nut.
  3. Adjust the rear wheel until you achieve a perfect balance of belt tension and belt alignment.
  4. Tighten the axle bolt.
Scooter Belt Breaks and Falls Off
When the belt breaks and falls off the scooter, it is often due to too much belt tension, a pebble or branch getting caught between the belt and gear teeth, or belt wear.
It is common for electric scooter belts to break, fall off, and get lost on the road. If your belt is lost, there are several ways to determine what size belt you need.
How to Choose the Correct Drive Belt
  1. Inspect the Old Belt for Numbers and Letters on the Outer Side. These numbers and letters may be combined (5355M15), separated by dashes or slashes (535-5M/15), or only the first 5 digits may be present (535-5M or 5M535). Depending on the belt manufacturer, there may be other variations.
  2. Purchase the Same Model of Drive Belt from a Supplier.
  3. If There Are No Dimensions Printed on the Belt.
a) Measure the Belt Loop Length.
b) Measure the Distance Between Two Adjacent Belt Tooth Peaks.
C) Measure the Width of the Belt.
  1. If the Belt Is Lost or Missing
Wrap a short piece of wire tightly around the scooter’s drive belt gear where the belt would be located. Mark the point where the wire overlaps with a pen. The length between the pen marks indicates the approximate length of the required belt. You will also need to measure the tooth pitch and width of the sprocket.
