When I do transport my bike I use to use my truck to transport them, I just got a reese style rack for four bikes, on the wife's Van, so we would only need one vehilce to transport both the riders and the bikes. Three of them are no problem, the fourth, while it belongs to my 18 year old son, is a Mongoose XR-500. Tried test fitting the bikes on it today. But could not find a way of mounting the Mongoose to the rack. because of the unusual shape. Anyone out there have a way of mounting it ?
