What weird bottom bracket is this??? Help!

[Limey16]

Hi all,

Trying to remove a bottom bracket on a 16 inch wheel folding bike...and well it's weird (see photos) - Has 2 notches for a tool but there square?! Took pics of the other side of the bike too, If any wizards out there could tell me what bottom bracket this is and the tools needed/way to remove it would be awesome, have done normal Bbs on mountain bikes, but stumped on this bad boy

You'll need a peg spanner, similar to this

It's an old & cheap model.

The drive side (pic 1) should use a tool similar to the Park HCW-4
Note that the drive side is often a left-hand thread (on English BBs at least)

I take it you've already got the lockring off the NDS (pics 2 & 3).
I believe the correct tool for that side is the Hozan c-207.

The NDS may be removable with a drift/punch (eg a screwdriver) and hammer, or the peg spanner end of the HCW-4 may be up to the job.

Cool thanks for the insight much appreciated, so to loosen I'm going anti clockwise? If I'm looking at that side of the bike. Does the NDS side need to come off first? - which way would that be to loosen

I can bet you'll need s lot of force to remove that with a hammer and punch. Good luck.

NDS is normal thread i.e. NOT left hand thread.
