My Bottom Bracket...

I would, but I'm Dutch anyway. :D Looks like you've got pressed-in industrial bearings there and the only option is to smack them out and then replace them - use a rubber hammer for this and smack the axle. I'd only do that if you're having problems with them though, otherwise just leave them there. What brand is the bike anyway?

It's a Batavus Flying Dutchman, trying to work out an age on it at the moment, but not getting very far.....

Single speed, coaster brake on the back.

Looks a bit like this (but now in lots of pieces!

Does anyone know if Armourtex will spray the bike with the bottom bracket still in?
