Wow! Lots of fun. I might be hooked. I’ve ridden on roads for years, and did a couple cyclocross races last year.
I took my road bike out with 30mm cyclocross tires. It did really well. There were just a few short spots where I had to put a foot down to get through some big roots. Or uphill rocky sections. Probably could ride all of it on a real mountain bike, or even on this bike once I get more confidence and experience.
Was able to go pretty quick on most of it since it was mostly smooth dirt. Even did a few wooden ramp things (the banked riding ones, not the jumping ones).
I went to Town Run Trail Park in North Indianapolis. I’d call it a very good introduction place for newbies like me.
