Derringer Cycles has come a long way since we last featured the company two years ago. The Los Angeles outfit now has a mouthwatering array of custom-built machines on its website. It’s a throwback to the aesthetics of 1920s boardtrack racers, right down to the copper rivets, Brooks leather saddles and even, if you so wish, white tires. Derringer pitches its hybrids as ‘the next generation motorbike’—a claim that some electric moto makers might disagree with. (We’re told that ‘The ultra-clean four-cycle powerplant meets stringent CARB tier 3 emissions standards’—but as far as I can see, the Derringer cannot be sold in Europe, because it’s only certified to the obsolete 1996 EURO 2 mark.) The engine is a 49cc OHV 4-stroke that offers an impressive 180 mpg; the transmission has a centrifugal clutch and freewheel, so the pedals can remain stationary while the engine is doing the hard work. No two Derringers are the same, and they’re absolutely guaranteed to stop the traffic. Would you put one in your garage?
