Roadie here, I am looking to buy a mountain bike so I can start having fun riding bikes again. I've ridden 26" in the past a little and the wheel size felt perfectly fine to me, made the bikes feel quite playful and nimble. I have also test ridden a 29er with the wide bar meme recently and I hated the way it felt. Never ridden a 27.5", but as far as new bikes go I guess that'll be my only option.
As I said, I am looking to have fun on this bike, not necessarily to go fast- I guess a "trail" bike is the genre I am looking for. Budget is around $800-900. Full suspension would be nice. With this in mind, obviously a used 26" bike is going to be my best bet, but there are a few hardtail 27.5s that I've seen that, on sale, are in my price range. (Chainreaction has a few Cubes with 2x11 drivetrains, air forks, hydro brakes for around $800).
Is there anything in particular I should look out for, besides no coil suspensions?
Thanks.
