BMX bottom Bracket replacement
Hello
I have recently acquired a new dirt jump bike which is the ZOmbie Hucker 26" dirt jump bike.
I need to replace its bottom bracket and I want to use a new system which is the sealed bearing system for the bottom brackets.
I need to know what type of bottom brackets I have as I am totally clueless about this.

You have an OPC (one piece crank) bottom bracket and you want to replace it with a "Euro" bottom bracket.
In addition to the sealed bearing bottom bracket and crank you need an adapter. I'd try Dan's Comp. I'm thinking they'll have exactly what you need in stock. If in doubt, call them on the phone. I've had good luck with them connecting me to a person who understands what I'm looking for.

SO I need to find a converter/adaptor to convert my bikes bearing from the OPC to a euro bottom bracket. I have 42.5mm sealed bearings which I have bought do I think I can find an adaptor to fit this as well as be compatible with my bike.
Also, thank you for your store recommendation.

That is an American bb shell.
The adaptor is eccentric bb.
Are you running single or multi speed?
If single speed, you can use
1. Bmx euro bb and crank with eccentric bb. Euro is simply bmx cranks and bb mounted in a standard English threaded bb shell.
2. Bmx American bb (simpler).
3. If multi speed, you can use any standard mtb (for english threaded bb shell eg square taper, Hollowtech 2) bb with eccentric bb.
