I ride my bike every day ...
but: I'm riding my bike today

I ride my bike every day as long as it isn't raining
would be my immediate reaction (but if looking into the future I would say I will ride my bike every day as long as it doesn't rain).

sorry, you meant the raining part.

I'd say "I ride my bike every day as long as it doesn't rain."

You can say both.
I'd probably say "as long as it isn't raining"

Als Alternativvorschlag/Ausweichmöglichkeit.

Grundsätzlich aber mit dude in #3: present continuous, nicht present perfect (denk ich mal, aber ich kann heute Abend nicht wirklich noch klar denken).
