It just depends on how much range you want. If you want about 20 miles range, then a 48v 15 ah ping remains a good choice.
It's very safe, you really don't hear of pingbattery fires. The only one I recall in many years was a guy who let a sharp edge in the battery box short one.
It should last. My first one took me 7000 miles, and only died because I finally made a dumb mistake.
48v 15 ah is small enough to fit in many bikes frame triangle, or if not, carries pretty good on rear racks. 15-16 pounds
It will run a "typical kit" just fine. A 20 amp controller will not harm one.
What kit to buy? Well, there are cheaper options for sure. But on a firt bike customer service might be more important that cheapest. E-BikeKit has a very complete kit, very well thought out, and very good CS. You'll be dealing with a USA company, shipping from the USA. I like the direct drive motors. If you put 48v on one, you get real world 1200 watts. It's a motor that is a clone, or at least very very similar to a 9 continent motor. Generally rear motor is best, but front is fine for street use, particularly on a beach cruiser or other non suspension bike.

There are ways around the complexities but the end user has to.. i repeaat.. HAS to learn about the specifics.. some people do not, and are not willing, or able to do this. for those people a Ping makes perfect sense.

I am not too intimidated to consider going this route, but there is clearly much more to learn. I will now go research pack construction, but what would you all recommend for # of cells to power a 36V/48V DD motor, and what kind of controller would then be necessary?

I would be open. How slow is slow charging? Is it better for the battery, like I have heard for other batteries? Would I be up all night chaperoning the charge? If so, something faster would need to happen. Or back to Lifepo4's.
choices choices choices.
