Note 1: In the instructions, the manufacturer must warn the rider that a load added to the bicycle will lessen the stability and alter the riding characteristics of the bicycle. This complication is particularly important when riding with children who are near the high end of the weight range. 1.2 The following safety hazards caveat pertains only to the test method portions, Sections 5 , 6 , and 7 , of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
