Our disappointment is not evidence of any inherent limitation with e-bike technology, says Marc Fenigstein, CEO and Co-Founder of Bay Area eBike start-up BRD Motorcycles, but, rather, a problem of application. Electric superbikes are a non-starter, Fenigstein says-the energy requirements necessary to compete with a 400-pound, 186-mph internal-combustion superbike are simply too high. But what if you draw a bead on something more accessible, like a 250cc, four-stroke motocross bike? This is what BRD has done with its forthcoming RedShift, and unlike eSuperbikes that pale in comparison to their I.C.E. competition, a short test ride confirms the RedShift could be the best Lites-class MX bike on the market—regardless of propulsion.
