Hi, no, it's not finished yet. It is still a work-in-progress as it appears in post #47.

I got my FSIR 5.0 in Bangkok where I paid--if memory serves--THB17,800, or $510. Inner City Rythm marks them up about about $140 higher.

Steel/Aluminum? Incessant debate. Both can be good, folding or otherwise, if the design and manufacturing are good.

The 406 wheels will smooth out irregularities better than smaller wheels, but Singapore's cement and bitumen are quite good. Lived there a year plus so I have a decent sense of the place. Space is at a premium if you don't live on landed property, and are in an HDB flat. If so, you may want to think about a FSIR Spin 3.1. Sweet little rig.




On paper FSIRs look good. Ingenious fold, decent components, decent price, not heavy. Beyond that I cannot say.

Do you by any chance remember the name of the bike shop in Bangkok?
I have friends there, so maybe they can help.
But then again language may be a barrier, in which case I may be better off with Inner City Rhythm, at least they can speak English and has a 1 year warranty.

I am located in HK, where space is at a premium.
But am not sure about the tiny 16 inch wheels on the Spin 3.
So you purchased the Spin 5 after trying out Spin 3 I guess.

Did you live in NYC?
I did too.

If you're interested in the Spin 3, search for a thread by poster who bought a Solorock Spin 3 this summer. Apparently the Solorock Spin 3/5 are almost the same as the FSIRs. Solorock is a Canadian company that also sells in the US.

What do you mean about reports of FSIRs no longer folding? As in the latches no longer holding the bike folded?

This looks like a great design, strong and reliable. I was wondering about the pivot point,s construction...is there some sort of steel bushing or bearing that joins the two parts together?

I bought it at Hyper Bike. The owner/manager is a really nice, patient guy, and he speaks good English. He also responds quickly on Messenger. His shop is near the 'subway' (elevated like the 7-train in NYC), Ekamai stop. This wall art is right across the street.


Check out my thread, 'the Bikes of Bangkok' for more info on options in the City of Angels.

Yes. I grew up in NYC many years ago.

The person's weight exceeded the bike's capacity, and I think that's why the bike stopped folding.

Abu Mahendra:

Thanks for the info, I already touched based with Hyper Bike.

Cheers guys!!

Does anyone know who the manufacturer is?
I'm looking at how to get the Spin 3 in Europe.

The FnHon website says they created the FSIR brand. I tried calling with my few words of Mandarin, but couldn't communicate with the guy on the telephone.

I saw on another forum that someone bought a Spin frame from Alibaba from Banian / typhoon bike. The bikes are labeled Banian.
Spin 3.0 | banian folding bicycle

I asked Solorock but they don't think they can ship to Europe.

I asked the Dutch distributor for FSIR but they only import the Spin 5, won't import the Spin 3.

The main things I would change out would be:
11-34 or 11-36T 10-speed with Zee RD, shifter, chain
58T narrow-wide chanring from LitePro
Needs 130mm BCD crank (stock is 144mm)
Tern Cargo Rack
Schwalbe Marathon (Marathon Plus doesn't come in 305mm)
MKS quick release pedals
Ergon grips
Brooks saddle

I might possibly change:
Thudbuster seatpost
Handlebar stem to a Radius/Litepro/Dahon T for Tern Andros stem

The other things could remain stock but I don't know about the quality:
brakes / levers
wheel and hubs
headset bearings (seems difficult to change)

Hello,
the manufacturer is Typhoon Shenzhen Bicycles. I bought a frame there also, directly. The Spin 3 frames still show up on Taobao. I think the whole Spin line is phasing out, you have to be quick..

Thanks for the info. Any idea why it might be being phased out?

Anyone also know who the manufacturer of LitePro is?

I got a reply from Banian / Typhoon Bike and they don't have the frame in stock.
I could only find the frame online here on Taobao but haven't contacted them yet.

I found another brand, OTD, which advertises the Spin 2, 5 frames.
Spin ? OTD Bikes

They're all located near the same 5km road. Although Banian appears to be in an industrialized area, while the other 2 (OTD, FnHon) appear to be in high rise buildings, according to Google Maps.

Banian says they have fully assembled Spin 5 bikes available, but not the Spin 3.

I'm wondering about the strength of the "rhombus" shape of the Spin frame for loaded touring. If there was a diagonal somewhere in there, it would be stronger.

I'm trying to find an alternative to a fold in the middle of the main beam because of past experience, to avoid irreparable damage. I also want something that can fit inside standard suitcases after disassembly, without having to pay oversize fees for checking into an airplane.

Splithub posted a photo on another forum where he completely disassembled his Spin 2, fork/handlebar, and both main beams out. It looks very simple with light tools that you would normally have on hand.
http://www.faltradforum.de/download/file.php?id=1762

On the other hand, Dahon and Tern hinge pins usually cannot be removed, especially if the pin gets slightly bent because it would be stuck inside. So the size of the folded frame becomes oversize luggage. Whereas a disassembled Spin 3 only needs a 24" x 16" luggage ( 61 x 41 cm). A hardcase (medium) of this size is easily purchased on Amazon cheaply. While a Spin 5 needs 25" x 20" (64 x 51 cm) and needs a "large" luggage. 51cm though usually can only be purchased as 75-80cm long (29-31") and reaches the borderline max check in size, but still do-able.

I was looking around and saw a few posts about Giatex.
Giatex Pony 166




Because of the way it telescopes, it "folds" longer than either mid-hinge (dahon) or rotation (spin), but the Giatex is narrower because the wheels will be in parallel instead of overlapped, and anyway this usually isn't much of a problem in daily use. But what is interesting is that if you take out the safety screw at the back end of the beam, it looks easy to pull apart the 2 parts of the bike for packing into a suitcase. I can't tell how the fork and stem been attached, and they may be difficult to remove. If they're left attached on the main beam, it would need an 80cm ( 31") long luggage. If it's easily removed, then it would need a 70cm long luggage since the beam is longer compared to the Spin.

Other problems:
  • The seat/crank appears to be 5-10cm (2-4in) closer to the rear wheel than on Dahon's (heel strike on panniers, tipping backwards)
  • How did they solve the offset seat post alignment (is the rear wheel at an angle by a few degrees from the main beam?)
  • Finding a compact rear rack that can slip over the main beam when collapsing the bike
  • No eyelets for rear rack upper stays, need a custom bracket to attach to where the fenders go
  • No eyelets on top of the main beam
  • The 2nd rear tightening knob might make more sense being on top than under the beam because of the rotational stress of the parts
