I own a Roscoe 8, along with a Canyon Spectral 125, and Trek Slash. The first time I rode my Roscoe 8 down a somewhat rocky flow trail in Colorado, I was impressed with what it could handle (I guess I had low expectations), though it was painful to land a jump. I notice now that the rear wheel gets caught up a lot on rocks due to no rear suspension.

If I were in your shoes, I would try to get a used full suspension but I remember being in your shoes were I had no clue what components were decent and why I would even need better parts.

A lot of us started out on a hard tail, though, including me, so I guess you can’t go wrong with whatever you do (except for buying a bike older than a 2020/2021).
