For a single speed commuter, the fantom cross is better for you.
First of all, the moto track is a stripped down track bike as mentioned. Only water bottle mounts. No rack, no fender, no housing stops for brakes.
The fantom cross uno will fit large tires, has rack mounts, guides for brakes, and comes with your freewheel and dual brakes out of the box.
On a side note, I ordered from bikes direct before and package was perfect. Only complaint was the front wheel needed to be majorly trued. And they never fed the brake cables through the brake levers, yet they were fed through the caliper and had a crimp on it. Which made no sense.
