I own a 2020 Trek fx-3. It has plenty gearing for attacking hills, in fact after the cassette needed replacement I actually replaced it with one with a shorter range(I don’t remember the exact numbers but I believe the original was something like an 11-37 and was replaced with an 11-34). However i am somewhat disappointed in the quality of the components, specifically the bottom bracket and wheels, In hindsight it probably would of been cheaper in the long run for me to buy a more expensive bike with higher quality components. To be fair at the time I bought it I didn’t envision myself putting 600 + miles a month on it, so depending on the miles and abuse your going to put into it, it could be the right bike for you. On the plus side the handling, ergonomics, and breaks are spot on.
