Gas is expensive these days. Perhaps you’ve heard? Cycling seems so appealing except for your sweaty arrival at a dinner a long distance away. Imagine if you could pedal on the flat parts and be powered over the hills. Los Angeles’s Derringer Cycles has come up with a solution by attaching a small motor to a sexy-looking bike. The engine has a 1.8-gallon tank, gets up to 180 miles per gallon, and can push the bikes to speeds of 40 miles per hour at the times when you’re too tired to provide pedal power. It’s a little pricey for a souped-up bicycle, but, as you’ve noticed, gas is expensive.
