It's very much less convenient than a bicycle since it's bigger, less maneuverable, harder to get in/out and harder to "park".

Also, when commuting you don't need "fast". A bicycle or a regulated ebike are sufficient enough given the constraints you will encounter (lights, stops...). What makes using (e)bike to commute awesome is not the speed per se, it's the reliability. You won't be stuck (= taking part) in traffic, so if on Monday you take 30 minutes to go to work, it will be the same each day of the week. No need to rush to +30kmh between lights.
