I cant speak for the dirt jumper but replied about the roscoe I have in your other post. What I can say about the roscoe is at 53 I just crush everything. Wheelies are by far my favorite to ride and manuals I’m still working on but I can ride a good one out every now and then. My roscoe ,because its a 19 and your brandy new are a little different. Yours is slightly slacker and seat tube angle is slightly different as well. Also yours will have a better fork and hubs where as i did the rear hub upgrade almost immediately for tighter ratcheting cassette. Actually just bought my first full sus and still much faster on roscoe so lots to learn. As far as the roscoe, you’ll be very pleased and if you have skills to start with you will on another level instantly. As soon as you sit on it you’ll be grinning knowing you still have what it takes and a new bike just put you back in the game.
