Last month a video of the DERBI GPR EV showed up on YouTube. It was posted by someone who appeared to be working with Sevcon and it was hard to tell if DERBI was behind the bike. I recently found the blog of Derbi Project Manager Carles Carrera. And guess what, he has a detailed picture of the Derbi GPR EV front and center.
Carles describes the ground up development methodology DERBI and their partners used in designing and building the bike over the course of 3 months. He cites flaws in Brammo, Zero, Quantya, Vectrix mentioning thier “poorly developed mechanical platform” and saying they fail to deliver an electric motorcycle that has all drive components communicating in an orderly fashion.
