I recently bought a used XC 200 EPAS mountain bike. It was 480 km, like new. I am trying to tame the beast, the battery has an amazing autonomy, I did 70km with a half charge, I live in a very hilly region "Les Monts du Lyonnais". I'm quite big, and the transmission lacks gear reduction, that's the only complaint for me, 21 speeds would be great. The EPas is a step forward, why are you the only ones to implement it.
