Looking at bikes for mostly paved roads but also the occasional gravel road. 65 years old, 175 lbs. I'm more interested in how good it can climb a hill than I am speed. On my road bike I ride 15-20 miles quite a bit but anything longer is tougher on me now that I'm older. I want enough range for at least a 40 mile round trip ride once in a while with some reserve in battery to get me home if my legs get tired or my knee acts up and I want to crank up the assist. I like the idea of a suspension fork and the seat post I could always upgrade easy. Was looking hard at the Trek Allant+ 7 but then I noticed the Specialized Turbo Vado 4.0 which is a class 3 bike. I'm not against the faster bike but how much better would the Trek be on hills vs the Specialized ? The other question I have is on the Giant Explore. The dealer I talked to the other day was pushing it. Said it was their best seller. He sells the specialized but doesn't stock it. I noticed the Giant has a 400 wh battery vs 500 wh on the the other 2 bikes. Also by the time you figure the rack, fenders and lights it doesn't seem any better deal than the others. I'd like opinions on these 3 bikes or other suggestions. Thanks
