Nice FnHon Monsoon frame. I used to own a Blast in the same polished silver finish.
People used to turn up their noses at Litepro, but now it's become rather accepted and mainstream. Ditto for FnHon. I should know for I was possibly the earliest adopter of both product brands going back to 2016. I told you so.

Yeah I was thinking of getting a fnhon blast frame (it is ~30% cheaper here)
But people were saying that the Y-frame of the fnhon Monsoon allows for more power transfer
Was considering between the Tyrell (standard diamond frame with standard stem), Twitter f451 (standard diamond frame with folding stem) and the fnhon Monsoon, but decided to go for the Monsoon at 10x cheaper price
I am not joining any race soon, but I do like the idea of having the most optimized folding bike frame possible

I've seen folding stems from indonesia that have 31.8mm clamps for more handlebar options
I'm curious. In your opinion, which folding bike frame do you consider the best?

But if I had to pick one best, it'd probably be the FSIR Spin 5.
I saw for sale some time back, a very rare bike friday with monostays like the Spin 5, not even sure if production, it had a very low serial number. Almost always on this stuff, the craigslist ad is for Eugene OR, BF's home, so I'm guessing these made it out the back door, or were employee built, that's a fringe benefit, employees can build their own bike.

Those chainstays look stout, but I'm still concerned with no triangulation, although with no place to attach rack stays except the seatpost, that does discourage touring loads. Do the chainstays flex perceptably, to give some ride cushion?

Of course, I wouldn't think of defiling the bike with an eyesore rack.

Good to know. Yeah, it's hard to have chainstays like that with bending flex, without fatigue issues, hard enough with steel, but impossible with aluminum, the latter needs to be designed stiff to be durable. My road race bike is a relatively early aluminum, ultra stiff. Only in later years have I come to understand the appeal of those old handmade lugged steel race frames, in terms of ride.

The Gust 20" lags the Storm because tire clearance at the fork is limited to around 50-406 while the Storm can take up to 60mm meat upfront.
Gust 20"
In any case, the FnHon framesets are all great value as they, save for the Tornado, can be had for around $150.

Now, if you are asking about the FnHon models for 406/451 wheels, of which there are five, the Monsoon, Blast, Tornado, Gust 20" and Storm, I'd have to pick the Storm. But that's because I am partial to steel in these bi-fold frames, the material of the Storm and Gust 20". The great thing about the Storm is that it can be built as as two-wheelset rig with a fat-tire 406 wheelsets that can be swapped out as the need and whim arises to a skinny 451 wheelsets. It's got clearance front and back for both.

Do you prefer steel on a bifold for stronger at the hinge when open and more vulnerable?

Say... that Storm frame looks *very* similar to my 4130 steel Dahon Speed frame, elegantly minimal welds, good in fatigue strength, and in photos online (and yours I now see) it appears to be available with discs. If I tour with long downgrades, I want discs. That might be a good option for me, just switch frames with mine. However, between frame (even at that great price), new wheels for discs, discs, calipers, and levers, I'd be into the same cost as an Origami Bull (aluminum frame) with all of the above and everything else new parts as well, complete. But I'd prefer a 4130 frame.

I prefer steel for should it fail, chances are it won't be catastrophic but rather gradual.

I've been getting by on cheap components for 10 years now, not like my old road bike which was *at least* 105 on everything. The cassette that comes on old Dahons is really junky, incredibly poor attempt at shift ramps, not at all hyperspaceglide. But once I replaced the compact derailleur with a conventional one, it shifts like Campy. My low cost 2X hollow spindle crank with external bearings, been tickled to death by it, for the price of 2 chainrings. Other parts are top quality but got cheap; $80 blackburn rack from nashbar for $20 (the U-lock holder under the deck breaks on all of them, but I never use that). Profile aero bars found cheap used at LBS. Better wheels and hubs would be nice, but I'll put that money toward a new bike with discs.
Smart man, I think you're right about the steel. Even though, 7005 aluminum was a smart development, specifically intended for bikes, the strength of 6061-T6 but not needing post-weld heat-treatment for strength, that costs money, and increased alignment issues. 7005 you just weld and it's done. But I still have a preference for good steel, minimum 4130.

Just announced by Shimano - an 8 speed low profile derailleur with 11-45T cassettes, using standard hyperglide chains and cable pull.
https://bike.shimano.com/en-US/product/component/essa-u2000/RD-U2000.html
Looks like the simplest upgrade out there for an average 8 speed folder looking for a greater range.

While browsing Alibaba for some v brake adaptors, I saw both Fnhon Storm and Zephyr frames for sale. Has Fnhon changed their frame designs to omit the front luggage mount, or do they hide it better than on the aluminium frames where the mounting block is obvious? I can see that you’ve fitted a luggage block but I can’t see how to do it on the photos posted there.

Ka pai, looks like I will need to be careful of that factor when shopping, as that’s a necessary feature for me.

Microshift Advent Super Short with 11-38 9sp.
It's ostensibly a 1x drivetrain but I'm currently experimenting with 2x.
42/34 works but tops out at 71 gear inches. Low end is a nice 16.7 inches (likely a touch higher since I have larger tires than the 1.75" in the calculator)
50/34 works in the smaller (higher) gears but binds when trying to cross-chain 50x32 and 50x38.
May try 46/34 which would give me a 78" top end.

Which calculator are you using John? I ended up getting some odd figures off Sheldon Brown’s calculator that weren’t replicated elsewhere when I was messing around with small wheels there.
Duragrouch, that particular derailleur is designed for an 11-38T max cassette.

I could be wrong, but that derailleur jockey pulley looks too far aft; Not as much of a problem on the big cogs, but on the 11T it means less chain wrap and with that few teeth, it could make a difference in cog and chain wear. Also, because of the "diagonal/slant" linkage, in the current orientation, as the derailleur goes inboard (to larger cogs), it moves the jockey pulley aft; Normally, with the linkage swung more forward, as the linkage moves inward, it moves more down than aft. Very early Campag rear derailleurs had orientation like the pic above; Later derailleurs from everyone incorporated the slant lingage for more consistant vertical spacing between the jockey pulley and the cogs, provided the slope of the freewheel/cassette matches the slant movement angle of the RD. The above RD may not have enough slant angle to match that wide range cassette.

(above video) I guess that's how that one mounts! Only one I've seen with the parallel linkage almost vertical, except for old vintage Campy. Ooo, I notice that one pivots the cage halfway between the pulleys, I don't think that gives more capacity but may be much shorter, better ground clearance that way.

About the same. It's unfortunate that it's not compatible with Shimano 9-speed.
