Every time I see a video of someone riding an Enertia, I am impressed at how advanced the Enertia was when it was first introduced, compared with the more expensive 2008-2009 Electric Motorsport GPR-S and the 2009 Zero, which were its competitors at the time. The Enertia still has good performance several years later, while the GPR-S (now called Native) is sold as a you-build-it-from-your-own-parts kit bike and the Zero has only just passed the original Enertia in performance, but still does not measure up to the Enertia's quality of its chassis components.
