How can u turn a dirt bike into a petal bike?

Answer 1

Adorn your nice little dirt bike with flower petals letting them fall all around and there you have it,  petal bike!

Answer 2

I am assuming you mean a motorcycle into a 'pedal' bike?

This would involve welding a bottom bracket assembly into the frame(after removing engine) and sorting out your crank/chainline.

This bike would be heavy and cumbersome (although built like a tank!)

It would take a lot of engineering work.

My Advice: Don't bother!
