When the motorhome with rear bike racks went away and the pick-up towing a trailer was gone we tried a number of folding bikes that fit in the back of our jeep GC. Each one fit differently and felt different and we didn't want a custom built $1000 bike that may disappear at a camp ground. We settled on Giant brand, had a loaner for a weekend, The wheels are tubular and with a lot of spokes they are listed for 300# capacity. I may not hit that number but when the dog rides along I get closer. We ride for 20 to 25 miles at time, they are just about as comfortable as our full size bikes, just a couple of miles slower and fold in a minute in a bag. Check the Giant web site for specs on the Expressway. We'll have them in Texas, Utah and BC.
