So my opinion is that the best value ebike out there is the vvolt proxima and Sirius. Both are around $2.1k and both have belt drives and CVT 380% igh hubs as well as mid drive motors.
The only reason to get anything else would be if you wanted a lighter weight road style ebike. Or if you wanted something that was direct drive so you could Regen on hills. Or if you did a custom build that you could hack to go beyond legal limits. Otherwise, mid drive + belt drive + IGH is the best combination for ebikes IMO.
