What will happen?

I searched already and didn't come up with an answer. What can the police do if I'm caught riding within the 4th ring road? Take my bike from me? Give me a fine? Give me a warning? And what will likely happen? Give me a warning? Ignore me?

I teach at a school once per week that's just inside the 4th ring. I'm trying to figure out if I'm risking a 200 kuai fine or risking losing my bike if I just ride straight to the school. Alternatively, I could probably find a tingche just outside the 4th ring near my school and walk or take a bus from there...

Just wondering if anyone has any thoughts...
