Those are decals I made with decal paper I bought. I tried a bunch of different kinds which didn't work, I even got some custom printed from a company, but they ended up being terrible.
Eventually I tried this:
Papilio Glossy Self-adhesive Inkjet Vinyl
(atleast I'm pretty sure that's the one I ordered, they have a lot of products)
It's not super durable, you can see the difference between the freshly painted frame and a season of touring/riding, but that's what a bike would look like after a week on Isla Sorna

I had trouble finding high res logos too, I ended up having to remake them in illustrator, here's the files if you're interested:

And I'd care about you making a bike like that as much as the original makers of the trucks probably care about me copying their design for my bike . You could always make it in the red and grey style jeeps
