Lawless Rocket electric drag bike does quarter mile in 6.94 seconds, breaks 200 mph
The Lawless Electric Rocket drag bike recently achieved a National Electric Drag Racing Association record run of 6.94 seconds at 201.37 mph over a quarter mile from a standing start
Top motorcycle drag racer Larry "Spiderman" McBride has entered the record books once again by piloting the Lawless Electric Rocket to a National Electric Drag Racing Association record run of 6.94 seconds at 201.37 mph (324 km/h) over a quarter mile (402 meters) from a standing start. While the electric drag bike looks monstrous when posing for the cameras, it's simply jaw-dropping when on the move – as you can see from the video after the jump.
It's not the first time that the Rocket has broken records at the Virginia Motorsports Park near Petersburg, VA. McBride managed a time of 7.469 seconds at 177 mph (284 km/h) with a 363V version of the drag bike in September 2010. At the time, the build team said that once they'd found a way to put more horsepower to the pavement, the vehicle should be able to achieve 200 mph (321 km/h).
Ohio's Lawless Industries and Orange County Choppers (the custom bike shop responsible for the rather gorgeous electric Siemens Smart Chopper from 2009) found the answer in a newly-designed 355V/14.2kWh Li-ion battery pack weighing in at 268 pounds (121 kg) and packing 1,350 hp that was built by Derek Barger of High Tech Systems. The bike features an electric DC Drive System, a 13-inch diameter, 36-volt GE motor with a peak output of about 1,000 hp built by NEDRA veteran Dennis Berube and a 4,000 amp Zilla 4K EHV motor controller designed and built by Otmar Ebenhoech.
Shawn Lawless told us that the ultimate goal is to get under six seconds and over 255 mph (410 km/h). For now though, enjoy the following video of the bike's brief but astounding record run:

Way to go Shawn and the Lawless Team!! You've worked hard for yrs and it's paid off.
Wow it sounds insane too
I love how when you first get to the video, it shows the bike and what sounds like a monstrous gasoline motor idling in the background...First thought is "that's not an electric bike! I can hear the motor!"
That's really nuts and takes a person with a really big set of them to ride this thing.
I wonder : What are the G-forces on take-off and acceleration ??
It's a good thing that he is almost laying down and the G-forces would transfer through his body to his feet instead of just trying to hand on for dear life !!!
I was so confused about the engine sounds too. Luckily someone killed it before takeoff. Still i was expecting a quiet little whir, maybe some tire noise but something about that bike is loud and crazy still.
It looks like a handful to drive,its either on or off,instant full torque all the way.This from a little 13 inch diameter 36 volt GE motor, putting out 1350 hp.Electrics are 80-90 percent efficient.Electrics are the future
I'm guessing by now you guys know the "36 volt motor" was a misprint. @ @36 volts, the motor would need ~ 28,000 amps to produce 1300 horsepower and top speed would be anemic.
Considering they're using a 355 volt, 4000 amp battery pack, my guess is the motor was capable of handling 366 volts.
