check ur pm 😉

i use google chrome with autotranslate. of coz me also cannot read in chinese

Only 1 tip. Carefully.

I don't think so. The FnHon vg2018 (the vg actually denotes Verge, I think  ) folded size is (according to Tern's website) 38cm X 77cm X 71 cm while a normal 29 inch luggage size (external) is 67cm X 53cm X 33cm. So, very clearly you are unable to fit in.

BUT if you were to loosen the handle bar, take out and also take off the 2 wheels, line with foam, very likely you will be able to fit it in. Just a guess though.

originally,
the non adjustable height handlepost are come in as stock parts fnhon frame/bike. and yes, u change it later

oh ya,
from my experience buying fnhon frame, u can order what height do u want even though they didnt offer adjustable height handlepost. like my zephyr, i oder 31.5cm while stock height are 35cm bundle with.i had my friend oder for 39cm..

the price for bundle package (frame+handlepost) much more cheaper than u buy it separately.i've compare the different is around rm100+

if u got back pain, for 20inch wheel the best is to get around 35-39cm height depends on ur riding style

as for me, i cant go for lower than 29cm on my 20inch bike. the reason is i want to setup my bike accordingly same like my roadbike due to feel and riding position..my fnhon do have same position like my rb
