Any particular reason (lack of) throttle is a deal breaker? Perhaps you're getting older and have some ailments. The Bafang Ultra is probably the most powerful mid drive with throttle but the flip side is the motor (and bikes) will be significantly heavier. You're having to lift a 60-75 pound bike instead of something more manageable like a 50 pound bike. Conversely you could get something like the M600 which is a bit lighter.
I am with you on the throttle. I see no cons to them though. Weight? I only used mine three times this morning and only for about one to three seconds each time just while cresting short steep hills. I have no issue changing gears or PAS # but there are times that the short burst of convenient power is just what the Dr. ordered. Hey, it isn't mandatory one use the throttle but for the one ounce of weight I will take it.
I love all the bells and whistles that make riding an E-bike fun and of course easier riding. To me the throttle is one of those whistles.
