I got off work around 1am last night and it was below freezing here wich is very odd for Houston. I usually bring the bike in at night off the rack once administration leaves but we got busy and never got around to it. It is a singlespeed and when I got to pedal it like I am back spinning after a few rotations it engages as long as I keep constant pressure on the cranks it stays engaged as soon as I coast same deal a rotation or two before engagement. Bring the bike in my apartment now the problem is gone. Is this common with singlespeeds freewheels?
