Those jumps aren't that big they're fine though.
I wouldn't recommend riding trails without having any bike control at all.
I was pretty stoked today was actually the first time I ever went riding legit trails, in years I was never able to ride any because there weren't but since I have moved to Munich I have found some pretty dope ones.
I actually found it pretty easy, but still really enjoyable, the riders there were amazed when I landed a transfer 360 from one line to another.
Not having a helmet I kept on borrowing different friends ones and one of them had one of those full ones (motocross style), and I swear I am probably the first 4 pegged trail rider with a full helmet, gay as fuck but I only used for like 10 minutes.
