My bike was converted by a local shop that handles conversions. It is a front wheel motor but still pedal assist and NO throttle. The motor will only kick in and provide assistance if I turn those pedals but I have to supply the torque or it won't provide much assist. I am definitely getting a workout on hills using it. The front wheel motor makes handling a bit more squirrelly or twitchy.
My Specialized Creo with mid-drive handles much more naturally. Also pedal assist and NO throttle. You either pedal or you get no help. The harder you pedal, the more help it provides.
