Per my other post, I am looking at 3 very different ebikes. One of which is the Tern NBD. I like ride and size of the bike (I am only 5'2"), but I am worried it's under powered. Out of all the bikes I tried, it clearly took more effort to get up hills. Does anyone have some real world feedback riding this bike for a bit?

This is not a car replacement for me and will mostly be used for leisure rides and nearby errands. I would like to go 20 miles without thinking too hard about it. I don't have a lot of hills, but some bridges to ride over and some long inclines, but not huge hills.

It's only on sale until 6/1, so I need to decide very soon if this is the bike for me.
