    glitch

    something that really bothers me, when i am riding really fast on a track for example the big ride, and i land hard, my bike stops dead, or on ground hog returns when i go too high on the jump when i land i stop dead, its like i hit something on the side when i really shouldnt, is it supposed to be like this ??

    no bounce? no nothing? just a complete stop?

    I get that too on both of those tracks. On "big ride" during the first 2 jumps if I land with too much weight on the front wheel and "groundhog returns" just after the big jump before the slow portion if I land with both wheels down on the hump. I don't think its a glitch though, I think we're just hitting a plank on the track the wrong way and destroying the momentum.

    Never had that problem. When it happens, its my own fault... I just have to try to make the landing as smooth as possible.

    But one strange thing happened to my yesterday. I was about to do a nice landing after the long drop on classic... the whole bike exploded! Never seen that! I was about to make a good 0-fault time, so it was quite annoying.

    yes i have had the random breaking bike. once it just shattered and another time KABOOM! I've heard those breaks are random and I bet they have been seriously hurt some Marathon Achievement attempts.

    I don't think it's a 'glitch' so much as an undesirable result of the way in which the bike wheels are mathematically modelled. I get a similar effect happening in 'giant ball', where the rider will be happily rolling along, but the front wheel will suddenly grip the ball and the bike is thrown 'backwards' (relative to the ground).

    I'd be curious to hear from one of the devs exactly how these calculations are done. It's far from trivial, because the engine has to consider things like angle of the surface the wheel is connecting with, the resulting normal and frictional forces, suspension, momentum and angular moment of inertia of the wheel, resistance of the wheel bearings, any braking pressure being applied, the list goes on. Future versions could even incorporate tyre modeling and finite traction.

    If I had to guess, I'd say that the cause of this sudden stop has to do with the frictional force acted upon the bike by the ground, not being correctly distributed between translational and rotational effects upon the wheels. So when you land, instead of that force rolling the wheel, it pushes the whole bike back, slowing it down. But that's just a guess.

    Thats exactly what I was thinking

    I always thought this happened because the bike just bottomed out and got caught up on the ground. I don't know though, it might be a glitch
