Now you can have it either way.

BMW motorcycles have a wacky accessory power plug known as a Powerlet Outlet. It's basically like a cigarette lighter, but about half the diameter.

The upside to this Eurocentric receptacle is the positive snap connection. Anything plugged into it really locks into place. The downside is, well- almost nothing plugs into it. Most accessories are made to go into the good old 'Merican cigarette lighter receptacle.

A bike with two driven wheels has long been the goal of motorcycle engineers. But getting power to that front wheel and keeping all that pesky steering motion intact has been a challenge. Over the years designers have come up with schemes using belts, shafts and even cables to flexibly transmit power.

Robert Hackstetter claims to have cracked the problem and offers the world's first "All wheel Drive 1 liter Superbike."

Between 1909 and 1911 the Edwin F. Merry Company of San Francisco built 200 motorbikes under license from the Winchester Repeating Arms Company. This example is the only known survivor.
