I am having an issue installing a freewheel on my bike and was hoping the (not always so) nice people of bfssfg could help me out.

I am on a wabi classic with the stock wabi wheels that are fixed/fixed. From what I have read I should not have any issues installing a freewheel on this bike yet I am.

I have tried an ACS crossfire and a shimano sf-mx30 with the same issue. When I thread the freewheel onto the hub and then move the pedal a couple rotations the wheel locks up and stops moving. It is not coming in contact with any part of the frame or the brakes. It appears as if when the freewheel is being turned it is causing the hub to tighten down. Did I do something wrong? Is there a different freewheel I should be using?
