I’ve got the alloy freewheel. It was on the bike when I bought it, so I assume it’s standard. Although; the exploding diagram in the manual shows the plastic one with gaps on the flange.
Tonight; I gave it a new shot after fwd-bwd had kindly pointed me to this thread [url]Strida 5 yearly service - #5 by luketoh] in the Tips and Techs section.
Still now luck 
It feels like the freewheel and the wheel are welded to the bike… This weekend, I’ll put loads of CRC 5-56 on the thing, in hope that it looses.
… or am I missing a step? As I said, it feels like it’s welded. Can a really bad winter do that?
