A fun little puzzle if you've not seen it before: You come across these bike tracks in the snow. Was the bike travelling to the left or the right? (I first saw a puzzle like this on Futility Closet)pic.twitter.com/gKnFupKCrU

Left to right? With the larger amplitude wave being the front wheel.

Seems left to right but you can't be sure unless you know the length of the bike. 1. The wheel that turns more is the front wheel. 2. The rear wheel follows the front, and it's tangent should point to the front wheel at all times. This looks like the rear wheel orientation:pic.twitter.com/cDLlt6m7RD

Damnit! You posted the solution while I was writing my response.

left to right: the one with the smaller amplitude is the back wheel. at every point on the back wheel track, there should be a tangent line from that point intersecting the front wheel track such that it’s smaller than some distance (bounded by the separation of the wheels).

The front wheel must be the one making the biggest sways, and the back wheel should be follow at a lag. Ok, I stop here

Right, and phase of the smaller swaying curve should follow the bigger one (say -ve phase shift). Suggesting the bike is going left to right. Flipping the laptop screen upside down shows +ve phase shift (smaller swaying curve is leading) which isn't possible.
