Acceleration and ride comfort are amazing. It's ride by wire so it doesn't feel like you're riding a bike. In the lower assist modes, it feels like you're riding an exercise bike. I'd probably always ride it in 10 since you can just modulate the assist/speed by how hard you pedal and the max assist would always be available if you really needed it (by pedaling harder). The acceleration builds up smoothly and quickly. It doesn't lurch suddenly away from you like some motors do but you can do a bit of a burn out on gravel anyway. Overall, I found the power delivery very manageable. At first I forgot it was full suspension. Jumping on the pedals, the suspension was very firm - didn't spend any time adjusting it for my weight - but it still felt plush and compliant without being wallowy.
