if you have a towball/towbar fitting at rear of van you can easily fit a bike carrier. just go to ebay and search to find one that suits. i have a 3 bike carrier on mine. best to get one that folds down the benefits will be obvious when you own it. if you have a rear bumper but no towbar, just get one welded on (properly reinforced etc) and away you go. just beaware of the extra weight on the rear as it will affect the overall balance and may require some adjustment elsewhere. you can also fit these to the A frame with due planning. there are plenty of other style carriers available - just do some research to check how your van will be able to have it fitted before you buy. good luck

Most steel constructed bike carriers will start at about $79, then go upwards into the hundreds depending on the brand, quality, build material, mounting etc. I cant coment on the specific one in the article, but I would imagine a ball park figure based on similar bike racks at the $199+

My two cents.
