This is actually a mountain bike, despite the name (hybrid referring to having a battery, it seems).
You need a 700c (29", ISO 622) rim with a 135 mm OLD hub (a mountain hub spacing) and mounting for discs (your existing rotors are centerlock, so unless you want to use a different rotor or adapter, you should get a hub with that). Width compatibility is another thing to look for -- very wide tire on very narrow rim and vice versa are not good combinations. The freehub should be compatible with your cassette.
Note that a wheel that looks extremely out of true can often be made to work well with a bit of adjustment -- unless you're sure the wheel is a gonner, I'd try that first.
