Well you can pedal assist to a point you don't want to over rev the engine but to help it up the hills at the rated speed yes. If it's not running the clutch isn't engaged so you can pedal as hard as you like then. The 2 stroke HT kits have a clutch lever to use however you like the FD is centrifigal.
