For those mathematicians among us, David Finn has
researched the question about whether a bike could
create a single track like a unicycle.
Have fun!

cool!
While this is interesting to a point, some people just have way too much time on there hands.
The animations below show a bicycle (the black line) creating a single tire track.
In actuality, it didn’t show a bicycle creating a single track. It showed a black line making a single track. I find it highly unlikely that especialy in the looping design that you could ever get the rear tire to find the trail of the first tire. Now it would be much more likely the bicyclist could create the track while riding a wheelie.
