I got a Schwinn Varsity and I want to convert it (I have read all the negative things about weight, but I am ok with all that).

It came missing a front tire so I am going to get a new wheelset

This is the one I think I have decided on

Then
BMX 3/32" Single Freewheel Chrome

Origin8 Singlespeed/Fixed Gear Crank Set 165mm 46T Black

The other things I need are tire/tube and chain

Am I missing anything? Is there a way to do this cheaper (better websites/similar parts for less)?
