High-end Ori bikes

I just saw the high-end Ori bike in a central London store today. 8.7kg with carbon frame and Mezzo style fold from its 16" brethren. Folds only slightly bigger than a Brommy. Pricey at 2700 but saw on eBay as cheaper from Taiwan and I'm hopefully going there in October anyway!

I'm impressed that the bike only relies on the wheels folding along with the handlebar and the central frame retains full rigidity. Yes it's pricey but I'm going to book a test ride and report back.

Any thoughts welcome!

Pretty cool but i'm surprise why they have those pedals on a carbon bike.

So that's what happened to Velorution. Francis, I see you've been getting around the bike shops of the West End. Did you check out Tokyo Fixed? - found that when I needed some leather toe straps.

Anyway, cool looking bike, but not for me. Enjoy throwing my bag in a plane without much drama. I'd hate to have to xray it every time I arrived at my destination.

:-)

Cool!

At first I didn't notice your reference and thought that the bike would also have 349 wheels. I also think it's interesting that the stem is on the bottom instead of the top of the post.

Would carbon take the abuse on a folder? I do wonder!

If it's built to take the abuse, it will be fine.

While I only have steel bikes now -- I'm cheap -- I've slowly come to the conclusion that carbon fiber can be a durable and fine riding machine.

I'm rather split of why a folding bike would need a carbon fiber frame. On a road bike that is being ridden long distances or for competition, sure. But for a folding bike the only justification for it would be the lower weight when carrying the bike when folded, but you'd have to be carrying it a lot more than riding it in order to justify the cost.

I'd also be concerned about the ability of a carbon fiber frame to take normal wear & tear. The smaller wheels of a folding bike impact pot holes and other road obstacles differently than larger wheels, and more energy is transferred to the frame as a result. Carbon fiber frames are somewhat notorious for catastrophic failure under situations of high physical stress, and although a folding bike won't be ridden as fast as a road bike, I suspect the carbon fiber frame will be subjected to other types of physical stress that wouldn't benefit the material the frame is made of.

In a nutshell, it doesn't seem that carbon fiber frames would be of particular benefit to a folding bike because carbon fiber frames are primarily performance based. Since people aren't exactly buying folding bikes to record personal best times when commuting or on the velodrome, the bike is being marketed to the people who want to be the first one on their block to buy a carbon fiber folding bike, and who are willing to pay for it.

There's better reasons to buy a bike than that.

UK people do distances on folders, I've done several 60 miles and one 120 mile ride on mine. And people have done PBP on Bromptons. So there is a justification of the weight option.

My worry would be travelling. If you pack a steel/alloy folder into a case and put it in the hold of a plane, and it suffers the sort of impact that would normally only occur in a crash (eg dropped 3 metres; thrown around; been at the bottom of a 200kg pile) then it would by bent or dented or ok. So you'd know where you are.

But after a crash with carbon, you are advised to get an x-ray in case the frame has been cracked. That's fine if you know it has sustained an impact, but not so useful if you are unpacking an apparently undamaged bike at your hotel

As a layperson, I understand that it is easier to create carbon fiber frames in non standard shapes. When we think about interesting designs for folding bikes, they often diverge away from the standard diamond frame.

Weight, as (I believe) you mentioned does matter with a folding bike since there are weight limits for flight as well as instances where the bike is carried extended distances.

The maintenance issue with hairline fractures and such, is a real issue. Although I suspect that the failure rate is extremely low,

The failure rate is much less now the tech is tried and tested, steel frames sometimes fail.
If you can have the preformance and the weight saving why not have it ?
I feel some of the anti carbon feeling might be getting a little outdated.
For instance I feel safer putting power through a carbon crank than an old steel crank with cotter pins. It might not be a fair analogy, but it makes my point.
