This is a Costco purchased SportRack heavy duty 4 bike rack. This bike is really good because all the straps are rubber and the way the bikes are loaded there is no rubbing of the bikes against each other or against the frame. I used this bike rack for loading racing road and mountain bikes. You do need a trailer hitch. Also, if the bikes are not on it you can tilt it down to gain access to your vehicle trunk. This a one of the best ones out there.
