Appreciate the review, I've been considering a road ebike in the next year or two, and the Civante definitely is interesting. Good spot on the price/performance curve. The Giant would probably be the main other consideration, because I already have a Revolt-E and like my local Giant dealer.
Between the two, the Giant is pricier, but also has much nicer componentry (the Ultegra group on the Giant is up a few levels from the Tiagra on the Civante, and I'd bet the house brand stuff (stems, bars, etc) is nicer on the Giant as well. You also get a carbon fork on the Giant vs alu on the Yamaha. So you do get something for your money. Agreed on the battery (I've discussed at length in other threads). I'd have to figure out how consumption would be on a road bike vs my revolt to decide how much it really matters. If I can't get 50 miles on the std battery at basic assist then I need an extender/2nd battery anyway. Any idea what Yamaha charges for a spare?
Super sharp bike! Definitely let us know how it is as you get more miles on it. I'm super curious about the range you see.
