For you next bike you may want to consider building you own E-Bike. You can save a lot of money. I am considering the RADROVER bike. But at $1500, it is not anywhere on my priority list. I only paid $850 for my current bike. I got an entry level mountain bike with disc brakes and replaced the plastic rear deraileur and plastic crankset, and managed to get a decent battery. I got a 48V 15Ah Li-ion battery on top of that. I am probably going to get a bigger one, probably a 20Ah or 25Ah battery. i got a good sturdy frame and upgraded a lot of parts. I might add a better controller, motor, and front fork at some point. For a budget of $1500 you can do far better than what I did. Especially with good sourcing of quality parts at good prices.
