I've recently learned how to bunny hop. It's definitely a lot of fun. I've repeatedly tried doing a 180 (with no success). It mostly ended up having the rear wheel lifted, the bike rotated 90 degrees and landed perpendicular to the starting point (either with the front wheel lifted or stationary).
This obviously causes a lot of stress on the rims...
And soon enough, I started feeling vibrations from the rear wheel at high speeds when not pedaling. I've inspected the rear wheel and found out that the rim is bent pretty badly, but not enough to cause noticeable drag or any anyway noticeable affect my ride.
How dangerous is it? Can it make me fall, lose control or anything like that? Can I keep it until I feel comfortable jumping (and not practice this activity on the new rim)?
Can it be fixed in a bike shop (maybe by bending it backwards?), or the only way to fix it is to replace the rim?
If I have to replace the rim, how difficult is it to move everything else (disk brakes, gears)? Do I need to 'calibrate' the rim or anything of this sort?
And generally, anything I should know before walking to the shop and ask for help so they won't rip me off?
The bike is a Specialized Pitch Pro 2010 (Enduro full suspension). I don't really know, but I assume that the rims are aluminium (by look and feel). I believe these are the original rims on on the bike, the DT Swiss 445D, 32-hole.
