Cut off , notch, add a QR band, then put a smaller tube inside, for adjustable height.. ?

It's what I have had, on both Bike Fridays... factory done.

I just wonder whether we are set for some version of the series such as

First foldie purchased in Singapore by this newbie

Cautionary tale - Flamingos (Brompton knockoffs)...

time to *sell* the Flamingo (Brompton-esque folder)

with my anticipation heightened when hearing about a glued nut. In any case there is no rush, if there is something to be learned we will hopefully learn it. For the moment we can seat ourselves comfortably . Nail-biting of one sort or another may come later

Yes if they made them in China they would probably be half the price...
As I've said before, they could've probably knocked a couple hundred quid off the price if they'd moved the factory from London to Hull.

Thanks, looks to be easier if you live in Germany. If it was after market purchase without having to send them my fork, I might do it.

I'd assume he could send you a modified new stem as well - but obviously this is far more expensive as you have to buy the stem. Just ask him.
But other than that I am not totally sure about the usefulness of this mod today. It was initially developed by Steve Parry in the 90ies to achieve front suspension (by using a suspended seat post as a stem) and straight bars. At that time only the M stem existed. Today there's S,P,M and H, so pretty much everybody can find a fitting factory stem. I even own such a modded stem, based on an old MK2 stem but did not use it until now.

I wonder why Brompton chose not to go with an adjustable stem.

So 1.2~1.5kg saving over stock steel ones.
Hi Raxel. Where can one make special orders of a 1100 gram titanium frame? Can you share the link of the pics? Thanks!

One thing to clarify - 3sixty bike is NOT a random noname clone. It has proper dealership and distribution network and covered by warranty, just like brompton.

Those sellers accept groupbuy with specific finish and tubing options (they are build to order, after all) and I guess lighter ones are made with slightly thinner tubings.

Seeking advice

Hi, I tried to send a message but it won't let me. I recently got a Birdy Classic but realized I can't really take it to the bus with me, being on the bulky side. I'd like to seek your advice whether you would recommend the 3Sixty folding bike for someone who needs a bike for the first and last mile (around 3km each way). I planned to sell the Birdy to get a Brompton maybe but you know how expensive they can get. I'm thinking of getting the 3sixty and keep the Birdy. I've been seeing threads about the potential dangers about the rear weld etc but I'd like to take it from you since you've actually used it. What would be your recommendation? Have you also tried your builds on kind of rough roads?

Hoping to hear from you! Thanks!

The brazing line of 360 frame is not as clean as UK Brompton but it's total BS to call it dangerous. They use better material than UK one (4130 cro-mo vs cheap hi-tensile steel) and overall better components as well (one-piece crank, two bolt seatpost, CNC ez wheel etc).
Also the bike has been available in my country for more than a year now(with quite a number of buyers) and had no issues so far.

On the other hand, I have seen many people reporting issues with their expensive Brompton CHPT3 edition (painting issues, tire bursting after days of riding, steerer tube deforming etc.) Potential dangers?

No clue about CHPT3, but I have been over a number of new bikes, for myself, family or friends, and none has been as out-of-the-box reliable as either of our M6Rs. I am going through upgrades, but none of these has been forced on me, unlike with other bikes.

Thank you for your reply. Can you give some review about the riding experience on not-so-smooth roads and going up/downhill? Or maybe just an overall one. If you can also share pointers to make the bike lighter. According to my local retailer, the stock configuration is at 12.87kg so it's kinda on the heavy side and I'd have to cross a footbridge every day if ever I'll pick it up and use it for bimodal commute. Would really appreciate it. Thank you!

Ridiculous! There's no reason to not have an adjustable stem, except just because Brompton didn't want to.

V brakes, the ability to run wider tires, a wider rear triangle for more gearing choices, but even so, it is still good. Being almost 70 I see this bike as lasting as least as long as I will and I have tinkered with it enough to be able to do all the maintenance it might require with the exception of the rear triangle hinge spindle and building wheels. I do look forward to the wheel building at some point but I'd rather pay to have the rear hinge done.
It's NOT the ride quality which Bromptons are known for. It’s the compact fold.

Brompton's Achilles heel has always been the weight, which Raxel addresses. Berlinonaut just doesn’t get it, or just doesn’t understand what is really at stake: Brompton's design is copied because it’s a good design. But NO ONE tries to copy its weight!

(Say "No!" to $2,000 boat anchors!)

Hi Raxel,

Where did you buy those 3sixty bikes?
I live in Europe i would like to buy one!
is it really more cheap than a Brompton?
They've cutted any corners when building the bike?
They use hub for the 3 speeds version of they use "normal gears"?

Thank you!
