When we saw the Predator electric drag bike last Spring, it was rockin' a pair of Toyota Prius battery packs. While it ran the quarter-mile quicker as quick as a Tesla Roadster with a time of 12.40 seconds at 94 miles an hour, its quickness wasn't quite as impressive as its Predator-themed appearance. Well, now it is.

Last week, packing a battery made of FlightPower lithium-polymer cells – the kind more often found powering radio controlled aircraft – the sci-fi speeder shot down Rochester, New York's Empire Dragway in 8.6 seconds at 143.95 mph with Jeff "Dice" Disinger behind the handle bars. The performance makes the Predator the new NEDRA record holder in the DMC/A (drag motorcycle, less than 300 Volts) category and marks an end to an amazing season for both bike and rider. Respect.

It was almost a different, much sadder story. About a month earlier at another track, Disinger made contact with a guardrail at 130 mph. He managed to keep the bike upright, but his right hand received multiple fractures despite titanium-reinforced gloves. Luckily, he recovered quickly enough to attend this event and make a number of runs without (too much) agonizing pain.

Disinger hopes to continue improving the bike's performance next year and perhaps make it the quickest motorcycle in the world. Hit the jump to get a look at his record drive, which includes a nice pre-run smoke show.

      it's not bad and quite the showmanship but making it lighter and more aerodynamic would allow him to take a real record. and that probably wouldn't involve that massive predator head up in the wind. as funny as it is : )

        what would you consider a real record?

          faster than the rocket. world's fastest of course :) not that 8.6 isn't fast. it's very fast. few would dare drive it. it can just be faster still : )

        It is lighter. The battery weight is likely cut in half.

      Both the Predator (recent NEDRA record in the sub 300V class) and the Lawless Rocket (holder of the quarter mile World record) have been upgraded to FlightPower Lithium Polymer batteries as also used in the Black Current III (holder of the NEDRA record for fastest street-bodied car) designed by Julian Cox, a leading pioneer and market leader for the past decade in the development of extremely high power Lithium Polymer batteries: www.flightpower.eu

      I can't believe they did this with LiPo cells. There is obviously a lot of room for improvement in these times and speeds. I guess their still in the baby steps stage.

        I can't believe they even bothered with Prius NiMH to begin with. High discharge RC Lipo cells are the most powerful and lightest thing on the market. I run them in my electric bike for a reason.

        FIRST OFF...this was the fastest bike with Nimh to date i believe? it actually ran a 10.24 @ 117mph! money is an issue on why i ran these batteries...i'm poor...lol! so,my main sponsor and good friend and also the world record holder for an EV motorcycle...SHAWN LAWLESS was nice enough to lend a battery pack to make this happen! the bike will go much faster as we raise the amps! the ROCKET has run a 7.13 @ 187....baby steps my ass! lol

          hehe, 8.6 seconds is most certainly fast. much faster than should reasonably be applied to road vehicles. as Bill Dube showed us : ) but even faster records on the drag strip helps us wake up the dead. I think it is possible to do a top fuel dragster time with electric drive. even today's technology. and still be super efficient unlike top fuel.

      The Predator has gone from 12 seconds to 11 seconds, to 10 seconds, to 9 seconds, to 8 seconds in the 1/4 mile, in just a couple of years. This is a 7 second bike with the addition of bars and a few more battery cells. The motors were limited to only 125 volts. They can handle 200 +. Also, This was an initial test of a brand new battery pack that weighs less than 100 lbs and only set at 60% power. The percentage performance gains that the Predator has achieved are almost unheard of in drag racing. This is technically the third quickest electric bike on the planet but stay tuned, The Predator is only just now picking up up the scent of it's prey.......

        hehe sounds good. but you really should try aerodynamics too some day.

          well, roughly speaking the bike is as unaerodynamic as can possibly be. aerodynamics is a very particular lady and if you do it right she really puts out. but if you just make something with little regard for aerodynamics she can be a real bitch. drag race is heavy in acceleration so most of the energy goes into that at least at the beginning so good aerodynamics might not make a huge difference but if it was steady state driving it would be 3 times faster with the same power. I'd guestimate you could cut a second or even more off your time with the same weight and power if it had a significantly more aerodynamic body. wind resistance grows very dramatically with speed. if you look at a glider aircraft like this http://hight3ch.com/wp-content/uploads/2010/08/jet-glider.jpg you can get a sense of what an aerodynamic shape is. basically a monobody meaning one smooth curve from front to end with a front that splits the air either bulb or somewhat pointy and a back side that tapers the air gently together again. just throwing the air out to the side and leave it hanging there really pisses it off. the back is super important. off the top of my head I'd suggest designing such a body to fit over the bike and cut out a profile in the sides where you and your legs fit in. the cut should be in a section where the body work is aligned with the direction of speed such that the air doesn't have to climb furhter out to catch the next surface. the back side can even be a bit smaller. at 144mph you might be spending 200 horses just to maintain the speed against the wind. just the wind. that's power better spent on acceleration. with the right body work you might be able to cut that by a factor 4. maybe more. if you have speed vs time data for a run I can maybe estimate how much the air means. or better yet a coast down test where you just let it slow down from say 100 to 50mph without brakes. also speed vs time data. from that an approximate coefficient of drag can be deduced. as well as an estimate for how much quicker the quarter mile can be with improved body work. shaving off weight is also super important. it might well be possible to optimize it all the way down to 5 seconds.

          body work a bit like this motorcycle but it should cover the front wheel, head and back too http://www.instablogsimages.com/1/2011/07/20/world_speed_record_on_motorcycle_ilixd.jpg and of course better to have the head low because the front profile area is important to drag.

          if you noticed...i did drop my full pred helmet for that very reason! i have many different airbrushed versions and i'm not sure how much more aerodynamic you can get. i stopped wearing the helmet in the top picture a 10.40 as i felt that was just pushing it. 30 years of running bikes and cars so not my first time at this...lol.

      'Bout time they put some real cells into one of these drag bikes. I bet this bike weighs half as much. I run these cells on my eBike because they allow me to have a 30 mile range @ 30-40mph and the bike is still light enough to carry up multiple flights of stairs into my apartment. And the discharge is knock-your-socks-off fantastic. 20C, all the way up to 65C if you want to spend the $.. It would be stupid not to run them on ... well, everything.
