I got my first hybrid bike "marin alp luvas valley" 2 days ago and boy...i am excited.

Anyway, the sales guy at local bike shop did not bother to tell me how to remove and install wheels so here am i..

How can i know i have tighten the quick release tight enough? i noticed the quick release (cam lever) on the rear wheel is very tight, after i unlocked it, i had to use two hands to push the lever back really hard to get it in lock position, i was afraid i was going to break the quick release.

Is it supposed to be this hard, or i did something wrong?

thanks
