The Bicycle Pulling Puzzle
bicycles reviews | bicycles videos | bicycles online
If you pull straight back on the lower pedal of your bicycle, will the bike move forward or backward? This classic puzzle has a surprising twist, so be sure to think about it carefully before watching the answer in this video. The puzzle is discussed in many publications, but none of them present the whole story shown here, as far as I know. Source: http://www.simonsfoundation.org/

What about the 'equal and opposite' force on the ground relative to the bike? Would the bike move back if you were on it and reached down to pull the string?

Depends on how hard you pull, gear ratio, etc.
