Finished mine today, took it for a quick ride too.
Feels like I’ve just got a big boys bike after outgrowing my 26er! Not sure if that’s a good thing or not at this stage? It certainly feels fun if a little slow steering. I need to drop the front a bit, so flat bars will be a must.
I will put gears on, but it’s just not worth it right now as it’s more about bog snorkeling then MTBing.
I also had trouble with the rear post mount for the caliper, it seems to be about 1-0.5mm too long, I didn’t need to drill anything but the bolts were a bit tight. Also the seat tube is a bit slack, I’ve got three 31.6 seatposts and all had a bit of play round them. I’ve had to really tighten the seatpost clamp to stop slipping.
And some more pics of the tyre clearance with a 2.3.
