Answers.Text: Perfect! Just a note, i had to use those 4-part sticks in a regular round hole, or else it wouldn't turn. I had at first used a double part stick, half round and half split, but the round part fit too tightly to spin.

  I would like to create a LEGO bike. I can imagine how most of it would work, but i'm stuck at the chain.
  
  I need a way for the turning pedals (at one spot) to cause the wheel (in the back) to spin with them. A design like the classic bike chain would be nice, but something else that does the job would also work.
  
  It would be best if a solution uses standard pieces, but i do have a few special pieces.

  It looks like LEGO sells [chain and sprockets](http://rads.stackoverflow.com/amzn/click/B00G1OURZ2), don't know if you'd have them lying around though.
  
  You could also try using pulleys instead. If you don't have any of the actual pulleys, take the tread off of two wheels and stretch a rubber band across, that should work too.

  The Technic [Riding Cycle](http://www.bricklink.com/catalogList.asp?catType=S&catString=36.682.225) theme features several bikes that may be of inspiration. One particular set [Moto Cross Bike (42007)](http://www.bricklink.com/catalogItem.asp?S=42007-1) uses several [3711: Technic, Link Chain](http://www.bricklink.com/catalogItem.asp?P=3711) parts to make a chain.
  
  ![enter image description here](https://i.sstatic.net/48inv.jpg)
  
  Based on [Bricklink prices for the last six months](http://www.bricklink.com/catalogPG.asp?P=3711&colorID=11), 39 chain pieces (the amount shown in the set above) would cost £4.29 (Aprox. $6.91 or €1.26).
  
  Pulleys and rubber bands are generally more commonly found in sets but they don't tend to provide as much traction as a gear and chain.
