Actually, this concept bike has been around since December last year. Fully inspired by the TRON: LEGACY movie, the new Electric Tron Lightcycle was designed by Parker Brothers Choppers located in Florida. Their motto is "If you can dream it, we can build it!" and they've certainly delivered that bold claim in this case. The design model they used is shown on the left from a display at a Comic Convention last year. Despite it's engine-like sounds, this lightcycle bike is fully electric. Thus it has no engine and no gas tank. It can move for about 100 miles before it needs a recharge, and I'm uncertain about its top speed.
