A major cause of accidents among juvenile riders is riding a machine that’s too large for them to handle physically.

  • Leg Length: While seated with both feet on the footrests, the child’s knees must be bent in at least a 45-degree angle.
  • Arm Length: When seated on the machine, a child’s arms should be long enough to:
    • Operate the brake lever. The first joint of the index finger should extend beyond the brake lever when the child grips the handlebar.
    • Reach the handlebars with a distinct angle between the upper arm and the forearm.
    • Turn the handlebars back and forth while maintaining throttle and brake control.
