I'm about to head on vacation to Emerald Isle North Carolina, where I've been in the habit of doing 30-40 miles a day on my recumbent bike and trike. I have a Challenge Fujin SL two-wheeler and a Challenge Trike. This year I'm taking just the trike. Here's a photo of it on the rack for my now-departed Chevy Volt. At first I thought that I'd not be able to take it with me this year because I don't have a hitch for my Model S. But then I folded down the rear seat and took some measurements. Much to my surprise it will fit -- that's a cavern back there with the rear seats down. As the photo indicates, it's a large machine: about 80" long, 34" high at the top of the seat back, and 32" wide at the two front wheels. With the seat removed from the bike (only two bolts to do that) and the rear seats of the Model S folded down I can roll the bike into the car rear wheel first and it will fit easily. When I load it in the car Saturday am I'll take an post a few photos. BTW, this thing is a blast to ride. It's fast, incredibly comfortable to ride (especially for someone with a bad back like me), and very aerodynamic for a bike.
