Sadly, no. I personally think tallbikes are rad as hell. I've got this idea of making a tall bike with a triple chain. Using a multicog freewheel and 2 sets of 2 ring cranks(one on the bottom frame without arms, one on the top to pedal) and making a triangle with a chain from one back cog to one ring on the bottom crank, then a chain from the other ring on the bottom crank to a ring on the top crank, then a chain from the other top ring, to another cog on the back. You would lose a ton of pedaling energy, but it would look damn cool, considering you could weld the frame straight enough to keep chain tension. I've never seen it done.
