hahahha.. im on journey to build my 10th bike one by one collecting parts 🤭😅
hope i can stop it
last time if im not mistaken got oyama bike with sram x4 groupset. but dont know still exist or not.

newer bike nowdays,
more likely will have ltwoo/sensah or some shimano compatible parts but not shimano. if u can find full shimano parts for folding bike, never doubt to buy it.

in your case, if u like sram parts u can build on your own. i love sram shifter bcoz of the ergonomic feel and pull ratio (exact actuation system) between road and mtb are the same. and that is another reason sram dont have like shimano grx groupset coz both road and mtb can be mix and match easily.

as an addition,
if u wanna setup full sram component, bear in mind sram road parts crankset (must gxp, bb30 cant fit folding bike) and fd (brazed on) quite hard to find either used or new coz malaysia market  have tons of shimano parts either new or used.

last time i mix sram mtb and road component. sram x5 9s shifter, sram mtb casette, sram x5 rd, shimano fd and sram apex crankset. after collecting part by parts for 5 years (mostly used), now im running full sram road component.
