-Bicycles periodically crash or become involved in accidents for reasons having nothing to do with the trailer, tow bar or receiver, and Burley has received a total of 35 reports since 2009 from consumers who requested a replacement receiver through Burley’s Return Merchandise Authorization (RMA) process. Some of these receivers may have broken as a result of crashes having nothing to do with how the tow bar was attached, but some may have resulted from the way the tow bar was attached.-These numbers are extremely small in light of the number of the units in the marketplace, representing about 0.1%.
