I've been wimming for about 5 months now and my kick, altough a little
stronger than when I started, is not very strong.

On kickboard reps, my legs run out of O2 VERY easily.

Some people think bicycling or running might help, as well as
compliment swimming.

I think my ankles are flexible enough. My quads just run out of
energy.

Any ideas to help this?

Frequent, sub-maximal practice is the key to progress at many things.
Take it easy, take your time, stick with it, and get in the pool three
times each week or more. Have a swimming teacher or coach look at your
kick and give you some pointers. The lower body muscles are much bigger
and can suck up oxygen, which is why you won't see a lot of
long-distance swimmers working their kick really hard.

Using a kickboard is, for many including me, harder than not. Try just
getting into a streamlined position and kicking with your face in the
water, taking a stroke when you need a breath.
