I was in Chicago this week and visited this shop (in Lombard)

They have some really cool old bikes like this Schwinn track bike

Or this BSA track bike with wooden rims.

And modern stuff like these three. A PK Ripper which is basically a BMX with fatbike tires
What is supposedly a Cannondales entry into the fatbike market
and a fatbike cruiser with Vee brakes. Never seen a fatbike with Vee brakes.
