The KillaCycle team has been working on their electric drag bike for some years now and it has gone through many evolutionary changes. Designed and constructed by engineer Bill Dube’ it now has a battery pack from A123 Systems consisting of 880 2.3 amp-hr Lithium Ion cells. Each 3.4 volt cell puts out 150 amps! If you’re not an electrically oriented person, trust me, that’s a LOT! The cells connect to a Zilla 2K-HV motor controller, made by Cafe’ Electric which sends a 374 volt, 1350 amp flow of electricity from the battery pack to 2 modified 6.7 inch Model L-91 Advanced DC Motors.
The bike weighs 625 pounds, uses about $.05 worth of electricity per run, can be recharged in 12 minutes, which is a charger limitation since the batteries can actually be recharged in 5 minutes, and it can make 6 runs per charge (not at full power).
What does it all mean? Last December it powered the KillaCycle to an 8.76 second quarter mile at 145 mph, a new record for electric vehicles of any kind, car, motorcycle or anything else. 0-60 mph is 1.4 seconds. Except for the whine, pretty quiet, too.
That kind of performance, impressive by any standards and improving fast, means we’ll be seeing more of this kind of racing performance from a lot more vehicles. It also brings in a new group of racers, a group very comfortable with electricity, electronics, computers and all of the latest technologies which can only be a good thing. If you turn down the power on one of these motors the batteries last a lot longer, too, which brings electric motorcycles into the realm of practical vehicle. Electrics are getting closer all the time.
