The KillaCycle is an electrically powered motorcycle purpose-built for drag racing. It was built and is managed by a small motorworks team owned and run by Bill Dubé. For ten years until December 2010 it was the fastest electric motorcycle in the world.[1]

Technical specifications[edit]

  • Weight: 281 kilograms (619 lb)
  • Battery pack: Lithium iron phosphate battery pack, made of 990 A123 Systems M1 cells, combined voltage of 374 V,[2] weighing 79.4 kg. Energy content 27 megajoules (the energy of 572 ml of gasoline), rechargeable in 10 minutes.
  • Motors: Two Model L-91 6.7-inch DC motors, 2,000 ampere each, switchable between series and parallel connection, giving 2,000 foot-pounds of torque on the back wheel.[2]

Performance figures[edit]

  • Power: 260 kilowatts (350 horsepower)
  • 0–60 mph: 0.97 seconds, which is more than 2.5 times the gravity acceleration
  • ¼ mile: 7.89 seconds @ 270.36 km/h (167.99 mph)[1]
  • Top speed: 274 km/h (170 mph)[3]
  • The bike uses 2.12 megajoules (0.59 kWh), or roughly 7 U.S. cents' worth of electricity on a run down a quarter-mile drag strip,[2] which is the same amount of energy stored in 65 ml of gasoline.[4]
