The bmx donor bike is my old 2013 Sunday Primer. Parts transferred from the bmx are handlebar, and the stem. Other available parts are fork, rims, and crankset. The bmx is a 3 piece crank with 8 spline spindle.
The bb shell is a BSA threaded 68mm wide.
Nothing wrong with the stock crank, but it is my dream to make this bike as much bmx as it can. I already have the crank and a haro spider with 44t chainring.
I'm located in Malaysia.
Be careful trying to do BMX stuff on it. Folding bikes aren't really designed for tricks and such. If I were doing it and I could get a Shimano External Cup BB to work I would do that, they are generally low cost and decent. I don't know the Malay market so well so I cannot speak to availability of everything over there but hopefully you can make your odd dream come true. I would much rather have a more capable bike that is an actual BMX or a sturdy mini velo rather than a folding bike that looks the part but won't handle actual BMX.
