Eva Hakansson and Bill Dube, a husband and wife from Denver, Colorado, have spent the bulk of their free time over the past five years tooling away in their two-car garage. Their labor of love, an electric motorcycle called the KillaJoule, is now an official record holder. In late August, Hakansson, a 33-year-old PhD candidate at the University of Denver, and Dube, a research scientist at the National Oceanic and Atmospheric Administration (NOAA), took their backyard creation to the Bonneville Motorcycle Speed Trials in Utah.
