But mountain bikes apparently are very popular with upscale car buyers. BMW has developed a new unit of measurement specifically for the X3 premium sport-utility.
Instead of calculating cargo space based on the number of golf bags that will fit inside, BMW counts the number of mountain bikes.
"This demonstrates how our clientele changes," says Ludwig Willisch, BMW sales director for Germany.
In Germany, BMW certifies the X3 will hold two bikes in an upright position. But in the US, marketing boss Jim McDowell recklessly claims the X3 provides space for "snowboard, mountain bike or kayak" without specifying how many of each.
