I have been doing a 20 mile round trip commute with a few steep hills for the last year on a trek verve from 2019. It’s been more than enough for me. I used to do the commute ona regular bike for years, but I was getting old and although I could still do it, I felt like crap on some days and couldn’t always reliably happily do it, especially if I was slightly under the weather, or the weather or wind was really bad. Now I can always do it, no problem at all. It’s about 40 minutes. I don’t think it’d be much faster with a 28mph motor…maybe shave 10 minutes? As for the hills, one is very steep, I crawl up it ona regular bike, and I still crawl up it on the ebike, but go a little faster and im not huffing and puffing. in fact, it barely feels like a hill, but again, im moving slow, maybe 6mph? I don’t think more power would enhance my commute, this is enough. I am not a super strong rider, justa regular recreational rider. Perhaps it would be different if I were a weak rider? I bought the bike because the dealer was nearby and I too was concerned about problems. So far, 5000 miles, zero problems. Except for chain drop. I really dislike the chain drop, chain gets really wedged in there and its difficult to pull out. I paid 2,000, worth every penny, even if the motor dies right after the 2 year warranty, but I doubt it will. To me, the warranty and nearby service is worth a lot. A bit more speed or power would not really change my commute much, although i wouldnt mind having it, just not for a big price jump. id be willing to pay, say, 300 more for the extra speed, just for the fun of it. but the 28 mph treks are way more than a 300$ price jump.. Personally, I think the verve is probably the right choice for your circumstances.
