Finally riding a big boys bike
Oh! Very interesting note. I intend to get this oma fiets up on my stand this weekend. I will look for more clues. Can't believe the seized bottom bracket is rolling freely now.

shall look forward to seeing what you discover when you disassemble the machine's chainset
at first glance one would assume some manner of a Thun pattern set however the shape of the black dustcap in this image is reminiscent of a Sugino product
the black plastic seal on the non-drive side of the bottom bracket shell may simply cover a conventional adjustable bearing cup and lockring
IIRC the black label visible on the propstand is one of the logos belonging to Intercycle
curious regarding the black rectangular item aft of the bottom bracket and forward of the mudguard
suspect it may be a battery for the lighting system designed to keep the lighting going when the cycle is stopped for a brief time

this image of the markings on front wheel rim shows a marking reading either "03" or "08"
should this refer to a date it would put the cycle later than would have guessed

Finally riding a big boys bike
After disassembling the crankset i learned some disappointing news. The black seal between the nds crank arm and bottom bracket is.simply a split plastic dust cover. It slid off the sq. taper spindle atter removing the crank arm. The bottom bracket bearings were caked with goo and rust. After cleaning all that off is when the disappointment came: It's just an axle on two SKF sealed bearings. They seem to be locked into the bottom bracket shell by some kind of hydraulic press that deforms the edge of the ahell, sealing the bearings in there, seemingly, forever. There is no threading inside the shell. No lock ring. Ugh.
Since they were seized, I pried off the outer bearing dust covers and sprayed in some PB Blaster to get things moving inside. I used some brake cleaner to wash it all out and filled it back up with Phil Wood bearing grease. It spins fairly well, now, but a bit gritty.
I read in some discussion on bikeforums that the bearings can be knocked out with a hammer (thats the manner suggested by Batavus customer service) but getting new bearings in and getting them to stay in may be tough. I found the replacement bearing spec online, but I havent decided yet if that's worth trying. I'm leaning toward not worth it. Fwiw, the bikeforums discussion was from '00 and the bike being discussed was an '88 Batavus Winner.
