Keep an eye out here on the forum, I will post when it is available to test.

A touring model with 3-pack mounts on the fork could be fun. Similar to the forks of the VO Neutrino and BF All-Packa

My nagging worry is that this Swift is going to end up being a Mule.

Please keep it light, fast and beautiful.

(Nothing wrong with mules btw. It's just that they're a different animal than a swift. Useful and affable as mules are they also lack a working pair of a certain part of their anatomy).

It will be very swift, and strong, and versatile, and beautiful.

I agree with that in principle but disk brakes need some fork stiffness that tends to bigger tires, and it was never 531SL to begin with. I think most of the compliance in this design is going to come from the long single boom.

Looking forward to seeing what off-piste mechanical stunts we can do with the steerer and headset.

Reportedly, during the U.S. Civil War Robert E. Lee asked Jefferson Davis for additional troops to push through Union positions. Davis declined citing the need to defend the Confederate perimeter. To which Lee retorted, "President Davis, the war is here and now. When you chose to defend everything, you defend nothing."

So much talk in this thread about wheelbase and stability, but IME one of the bigger factors for stability is having the grips have some distance from the axis of rotation of the fork. This is one of the reasons why Bromptons feel so "twitchy" is because handlebar mast essentially extends up the axis of rotation of the fork, and the handlebars are not set to give more reach. More distance from the axis of rotation = better stability. With that in mind it's nice to see that this bike has an actual stem, as that's going to do a lot to keep the bike feeling stable without negatively impacting the nimbleness of the whole package.

I have recently become convinced that the twitchiness of the Brompton is mostly from its low trail. So it's a trade-off for its good handling.

Looking good!

It looks like you've made most of the changes I would have wanted on my Swift: luggage rack (biggie), disk brakes (not as much a biggie).

As for the stem bottle mount, I use mine for a foldie lock.
It works quite well.

Pinigis 

We will have bottle mounts on the stem and on the top tube.

Headtube angle, fork rake and trail very much do play roles in stability; it is clearly not just wheelbase.

That being said, leaving everything else the same and changing wheelbase will directly affect stability.

I took a screenshot of this Origami logo on an unidentified bike currently up on the Origimi website. I like the font and the graphic.

Pinigis 

That is actually one of our Crane 8 models from about 8 years ago.

Nice prototype, Pinigis!
However, is there any reason to use a 34mm threaded headset? Otherwise, a standard 44mm internal thread-less headset will be definitely better.

Here are a couple of photos of our latest rear rack design. If you tip the bike back, it rests on the trolly wheels and can be rolled in its folded position.

Tip the back back to roll it on the trolly wheels

Looking good.
How's production going?

Pinigis 

Still trying to get the rack settled before beginning production.

Rack's more streamline. Is that a folding stem release I see or is it vertically adjustable?

Jipe

Didn't you consider to make a folding rack like on the Birdy ? I think that with a clever positioning of the two pivots, one on the main frame and one in the rear \folding part, it should be possible to do the same on your Swift and have a rear rack able to carry big rear panier without hitting them with the heels while pedaling

Here we have Jipe dispensing advise while only a few months ago he was hectoring and haranguing PP for doing morning more than selling PRC-made bikes. Rich. Very rich.

Jipe

What does such a stupid empty post bring to the topic ?

Siu Blue Wind

Stop

Pinigis 

OK, The rack with wheels was not stable enough to be useful, and making it wider is just not going to be an attractive option, so we are going back to the original rack and modifying it to look better.

joey buzzard

The Origami Swift will be most beautiful without a rack. While I think that it's great that there's mounts on the frame for a rack for those who want one, aesthetically such a thing will detract from the bike's sleek simplicity.

Xootr sold a beam rack specially designed to clamp around their model's over-sized seatpost. I toured with it in the Yucatan once and found it worked ok. It wasn't capable of hauling super-düper heavy loads, but carried my clothes no problem and performed better than other beam racks I'd tried in the past, I think owing to the larger surface area underneath the clamp on the enlarged seatpost.

Anyway, good luck whatever you do. For what it's worth I thought your last rack design looked ok, so pity it wasn't up to snuff. Can't help but think that maybe the gods might be saying "keep it simple" though. I realise that's my own bias coming out.​​​​

If you have a problem, put me on Ignore or bring it to the attention of the moderators. Until then, it is you who ought to stop telling people what and what not to post.
