then lets asume that I have a bike with me and pedal in the oposite direction just as fast as the station spins, effectively cancelling my rotational velocity.
as I rode faster on the bike I would lose more and more "gravity" until it eventually stopped and even the smallest bump would see me floating free in space again
No need to bring your bike - if anyone built such a spaceship, they would obviously include a non-rotating section for zero-g thrills.
Assume the spacecraft is a long cylinder with a spinning section at the centre (i.e. artificial "gravity") and a non-spinning section at either end. As you sat in the gravity bit, you would see your crewmates in the stationary sections appear to tumble round and round whilst they floated about.
You then take a running jump into the stationary section. What happens?
Well, you carry your angular momentum with you into that section, so you hit the floor, bounce off it, collide with your crewmate, send him tumbling into another wall and so on until you steady yourself on a grab handle or lose enough energy bouncing into the cushioned walls.
