I built up my yellow Fnhon STORM recently. The frame is made of CrMo 4130 steel, so it is not very light, approx. 9.4kg w/o pedals.
It is considered to be a leisure bike for short distance riding, so not many widgets are installed.
It has flat bar, ETRTO451 wheels, hydraulic brakes and 10s drivetrain, which together provide a brisk and agile ride.

Very nice! I think I'd probably destroy those wheels in about an afternoon and a half of riding though.

Aha~ Do the wheels seem weak for you? But I don't think so, as long as the rider weighs less than 90kg.
I am 85kg, and have been riding this bike for a couple of weeks. So far so good.

They seem similar to the kinetix comp pro that came with dahon Mu SL and premium tern Verge. these bikes were rated for 105/110kg load so like you say, if less that 90kg, it should be fine.
I rode light gravel/hardpack on kinetix pro with kojak and the load was about 78/80kg (70 + work bag with laptop etc.).

I rode a 16-spoke front wheel for years. I even toured on it, and the thing remained intact and true throughout.

<10 kg for a folding bike with gears and disk brakes is actually pretty dang light. I like it.

I built one last winter with some parts from my old Dahon Speed.

Could you please advise how this frame could be purchased online and shipped overseas? I can't find these frames on Aliexpress...
As well, when I entered fnhon.com, I found only V-brake version of the storm frame.
An additional question: it seems you are using 28-451 mm tires; could you please measure radial and sideways clearances at the: (a) fork crown, (b) seatstays bridge, and (c) chainstays bridge? I consider installing thicker tires - I got 44-451 tires from Vee Rubber.
Thank you very much!

if you are in contact with any FNHON dealer on Aliexpress, perhaps you can just ask him if this frame is available.
regarding the tire width, I have tried 35-451 and there is no problem at all, but I am afraid 44-451 doesn't fit any more. on the other hand, the bottom bracket will be too much elevated is your tire is so wide. Maybe you can consider 406 (for example, schwalbe big apple 50-406) tire instead.
