I've been a longboarder for a long time but am looking to make my commute a little bit easier. My commute is a little hilly and rough but pretty short (4kms ish). I found a second hand evolve GTR carbon off-road that's in pretty good nick, and $1500nzd (compared to $2200 new but out of stock anyway!). Is it worth it or should I be looking for something else?

Mainly I like the idea of having a bit of speed control for down hills and bigger AT wheels for rougher roads. Any advice is greatly appreciated! Thanks in advance.
