Bill Dube’ and Eva Hakansson, a husband and wife battery-building and electric motorcycle-racing team, have many world records of their own, but are always happy to help others win a few. According to their Facebook page, “The Drayson B12 69/EV electric car driven by Lord Drayson set a new FIA world speed record today for electric cars under 1,000 [kilograms] (2,200 pounds) of 204.2 mph (328.6 km/h). Bill and I are particularly happy for the Drayson team since we have been involved in the design of the 850 horsepower battery pack.” In fact, at last year’s CAFE Foundation Electric Aircraft Symposium, the couple discussed how they built the pack for the Drayson team, a meticulous and hazardous process that requires thorough grounding, both electrically and intellectually. As explained on their Facebook page, “The KillaCycle team designed and constructed the battery pack for this vehicle.  Mavizen put us together with Drayson and worked all the logistics.

One tenet of the CAFE Foundation’s outlook is that electric automobiles will be a major source of the new technology that will make electric aviation a practical reality.  Large-scale production numbers for cars mean lower prices, ubiquitous motors and batteries, and demonstrated performance.  Motorcycles offer another source for equipment that could see aircraft applications, since cycles share some of the same criteria for success, including light weight, compactness, and high output of both power and torque – especially true in the ultralight and light sport aircraft range. The motorcycle community’s normally lukewarm assessment of the prospects for battery-powered two-wheelers is heated up considerably in the November issue of Motorcyclist, and that bodes well for electric aircraft. Normally crowded with Harley, Ducati, and BMW gas burners, the magazine’s cover features a dynamic rolling shot of the recent Isle of Man electric Tourist Trophy winner. “SHOCKER! The Mind-Bending MOTOCZYSZ E1PC,” the cover blares, “165-MPH TOP SPEED, 135 HORSEPOWER, 250 LB.-FT. OF TORQUE, …
