New 3sixty bikes (Affordable Brompton Clone)
#26
The issue shown in the picture looks like the root cause would have been an overtightened stem nut. The question would be who overtightened it. Brompton is not free from failures but if they occur they usually handle them very generously (like the bottom bracket one lately). And if I remember correctly something was changed regarding the ti-forks not too long ago.
All others do as well.

They are not my bikes. Owners did place warranty claims and the local dealer said those Bromptons are modified (disassembled) by third party so they lost warranty. Fun part is that one cannot know their steerer tube is intact before taking the fork apart. They got a ton of flak for this policy and I think owners got them replaced eventually.
Dahon i.e. is famous for not doing so. Look i.e. at the thread in this forum dating from 2012 when Tern was founded and how people were joking it would would be a main differentiator from Dahon it Tern would actually offer spare parts.
Would be interesting to see how well 360 is able to handle warranty and support and spare-parts topics.

Pics tell you that something is broken, They do not deliver the context how and why and neither how the issue was handled. So what are you trying to prove? That Bromptons do fail, too? That's pretty obvious. If you want a product with more than 1/2 a million samples in use out there that has not had any issues: good luck. I think I know at least two if not all three of the pics you showed and if I remember correctly there is a story around and behind it that you missed to tell.

Hey Raxel, wondering if the 3d printed tensioner with chain pusher mount is being sold. I've been looking for a better solution than glueing a nut for it which is prone to misalignment since I can't find a guide of someone doing this except for you. 😆

New to this foldie. Previously got a dahon P30 bike but sell it off as its quite a speedy bike to ride. Trying to get a Brompton but it seem to be sold out and too expensive too. Came across this 3sixty on Korea website. Is this a good bike.

Cheap Brompton knock-off, and they don't sell overseas (Korea), which makes sense since those bikes are illegal.
If money is tight, consider the Dahon Curve (~$700), whose three-speed gear hub can be replaced with an eight-speed hub. Doesn't fold as compact as the Brompton, but cheaper, nice to have all the gears in the hub, and the Brompton baggage block can be easily modified to hook a Brompton front bag.

Ti and aluminum are subject to stress riser cracking..
the Ti tube wall thickness should be thicker than the steel..
For the fork steerer, it has to be added outside to fit the steering mast quill.. 1" inside..
so would be machined down @ the top for the headset threading.. ..

They're not. Or at least, authorities don't seem to care.
I meant: They're illegal in the absolute because they're just Brompton knock-offs, and the bikes would be seized if they dared selling them in the West. Which is why they don't ship overseas, especially to Western countries.
As to why Korea allows those bikes to be sold there is a mystery. It's a developped nation now and part of the WTO, but it looks like local judges don't care much about intellectual property when the owners are foreign companies.
Incidently, look what happened to Chedech, also from Korea:

"The CJEU ruling in Brompton’s case is potentially significant for many such creators, as it confirms that the prevalence of creativity in their designs may afford them copyright protection. However, it’s important to reiterate that the Brompton case is not yet over. It will be for the Belgian court to decide whether the design of the bicycle displays creativity and originality. Other recent cases have shown that the outcome of court rulings on copyright can be difficult to predict."

They are about the same strength which means they crack about the same stress. Maybe steel has a little more ductility but I don't know this and was hoping you did.

I've been a fan of your posts for years (partly why I bought a used Brompton)--but have to disagree with you on that one.
Kaizen originally came from William Demmings.
He tried presenting it to GM/Ford/etc. In typical American fashion, they shut him out.
He went to Japan, and was embraced.
His method was called the Deming method....later, Kaizen......later, Six Sigma...etc
Someone actually made a quasi-comic book of the guy and his methods. (highly recommended)

I'm a huge Japanophile, but give credit where it's due.
