Well, they call it the "Empluse". Maybe that's some secret combination of the Enertia Plus and the Empulse.. but maybe it's just sloppy journalism.
They also quote range and battery lifetime for the ZF9 bike at the top of their specifications list at the end, then quote weight, charge time, and then battery lifetime (again) for the ZF6 bike below. Plus they mention 10 spoke wheels.. my bike and the pictured bikes reviewed have six spoke wheels.
Despite the sloppiness, it's a pretty positive review of the Zero .. and I agree with some of their conclusions.
