After buying the two bike trailer hitch my wife and I thought that would plenty. Our grandchildren decided they would like to ride with us. Well after ordering the 2 bike extension which fit perfectly we are now able to take our grands with us. Best part about this is it fits perfectly on our older carrier and folds out of the way when not in use. A good product and a fair price.
