According to the label it is a TriMotive and would have been fitted at some point in the past 4 years. I am assuming it is a towbar connection and not a bracket for bicycles to be carried? It seems to have the connection for attaching the breakaway cable? All the detachable I have had previously the top end that fits into the bracket has been square and not round? Please advise as can find very little on TriMotive. Thanks.
