I don’t think $2500 will get me a mid drive.Are you looking for mid drive torque sensor or hub drive torque sensor?
That looks great. I‘m going to see if there are any dealers. I sure would like to try bikes out instead of online ordering. I get apprehensive about who can fix it if something goes wrong.$2499 +tax + freight. You have to page down past all the blather to see the claim for torque sense.ROOK

As a geared hub motor bike, not suitable for climbing 1000' of mountain in an hour. Rolling hills are not the problem since you can carry momentum from one downhill to the next uphill. I cross 80 of them in 3.7 hours on my hub motor bike.
With that small battery you better pedal.My Ariel Rider C class checks your boxes, but I'm doubtful whether they are still available. It's a step thru, upright posture, hydro brakes, Nexus7 internal hub, Tongsheng motor, 48v 10+ ah battery, has low-end fork suspension, and it has both torque and cadence sensing (if their owner's manual is to be believed). $1700 when I bought mine. I got it in 3 or 4 days, as I'm in Bellingham, and it came from Puyallup, WA. I've grown very fond of the bike. No problems so far--except the fender attachments are crappy. I ride 95% in PAS 1, use 2 or 3 PAS (out of 5) only for steep and/or long hills. It has a throttle, which only works on PAS 0, so I never use it. I'd rather pedal anyhow.
Yes, it is small. But so far it has taken me as far as I've needed to go. Would have to get another for decent range.With that small battery you better pedal.
Don't know if you're still shopping, but I bought the 2023 V Rook in September, 2022. The "V" designates a true step-through frame.That looks great. I‘m going to see if there are any dealers. I sure would like to try bikes out instead of online ordering. I get apprehensive about who can fix it if something goes wrong.
