Whatever you get, do lots of research on repairability. How easy is it to get replacement batteries? Are they using a proprietary charger with 5 pins, or an open source standard like XLR? Do they reuse battery standards like Juiced, or do they build proprietary batteries for each bike and generation?
Can it be serviced at bike shops (Aventon, Juiced, Grintech) or does it have things like proprietary bike spokes that take weeks to ship (ride1up)? How long do they plan on producing parts, like motors, sensors, etc. (if they are julet connectors, there might be aftermarket solutions)
These are the sorts of questions you may want to ask sellers when doing test drives at local ebikes shops, or online bike sellers.
As for recommendations, I really like the NYT's recommendation on the Haul ST:

If you can find a Juiced Ebike, I can also recommend them. They were recently bought out by Lectric. I have nearly 2,000 miles on my RipRacer and love it.
