I think Jetstream series are not intended for extreme riding, sure. However it's a very versatile bike allowing off-asphalt-road : wood trails and even light/friendly stony paths with some modifications. For hostile trails I'd be more careful.

In urban environment, I can ride aggressively without problems including sidewalk jumps.
