joint selection- bike falls apart

i am having trouble with joining pars of a simulated bicycle using joints between parts of the bike, in that the bike keeps falling apart even with joints... the odd thing is that it stays together without joints, but wont turn by itself when the bike starts to fall.

Is there a good simulation out there that helps you make good choices for holding a bike together?

 

Did you follow the guide how to stabilize joints? For example disable preprocessing?
Even with those guidelines its not perfect, example from our game
