Question

What is difference between ‘of you’ and ‘for you’?
Which of the two sentences is correct?

It’s strange for you to ride a bicycle
It’s strange of you to ride a bicycle

and
What is difference between ‘of you’ and ‘for you’ in front of ‘to verb’?

Answer

They are equivalent and interchangeable. Some people will simply prefer one over the other.

Answer

"It is strange for you to ride a bicycle" (or "for you, it is strange to ride a bicycle") means you don't think it is normal to ride a bicycle, you find it is strange.
  Example: ME: Is it strange for you to ride a bicycle?
                   YOU: Yes, I think it is really strange... I don't like bicycles...

"It is strange of you to ride a bicycle" means "it is unexpected" that you would ride a bicycle. it means "I" find you riding a bicycle is strange.
  Example: If you normally don't ride a bicycle and I see you riding one, I would say "It is strange of you to ride a bicycle"
