I'm not an e-bike person but have taken a spin a few. Specialized does OK on theirs. I think Orbea did it a little better in the fact that motor is barely noticeable. Took my friends Orbea for a spin a few months ago and it was OK, but not my thing. No work to get up any of the hills. Matter of fact no effort at all. Kind of defeats the purpose of why I ride.
