I can´t report my experience with it yet but the front fork looks quite tough and I am sure would not be out of place on a real mountain bike. I think the wheels (maybe even the skewers- I have bent them before on other bikes hammering over kerbs) would be the week link if you started some real kerb jumping as 28 inch hybrid wheels don´t usually stand up to this as well as 26 inch MTB wheels.
