XO Competition Bike

The XO Competition from Swiss Bike folds in half, and with the front wheel and seat removed, everything stuffs into a 36-by-28-by-12-inch carry bag.  Dad can put one in the trunk of his car or slide it under his desk at work.  $2,299 (the DX Crossover also folds and is $499): www.swissbike.com
