so i bought a folding bike from decathlon about 1.5yr ago and never been happier since. its following model:

https://www.decathlon.fr/p/velo-pliant-oxylane-120/_/R-p-120...

they actually went up in price since then. swapped stock tires because they were rubbish and also bought better seatpost from upper model. removed all the unneccessary stuff like ringer or mudguards and this thing flies. im getting average speed about 18km/h on my rides and done about 4000km so far without any problems. this is perfect city bike in my opinion. if this thing had disc brakes it would be even better.

I used to like Decathlon but their quality has gotten worse and worse. The bike I bought there 3 years ago or so must be the single lowest quality product I've ever owned. Of course when it's new you don't notice at first until things start breaking. It wasn't the same model as yours so I hope you have better luck but I'll definitely NEVER ever buy a bicycle at Decathlon again. Utter garbage.

Most stuff I bought at Decathlon was of reasonable (above-expectations given the pricing) quality. But now I'll need to find another place to shop, as they (with a number of other French companies) are expanding in Russia, instead of shutting down: https://www.theretailbulletin.com/sports-and-leisure/decathl...

You may have gotten a bad item. I bought an MTB from them 4 years ago, transformed it to electric (which it's not designed for), rode 10,000km+ on it, on many different roads, in all kinds of weather, and the thing is still as good as new. It's really indestructible. I also bought bikes for my kids, and had friends buy bikes from them, etc. Never had any problem.

Hard to do proper disc brakes without hydraulics and hard to do hydraulics on a folding bike. The minimum bending radius of the brake lines is the limiting factor.

[sudosysgen]

I have used hydraulic disc brakes and mechanical (wire) disc brakes. Yes, it's not the easiest to set up, but on my Hayes MX5, it works well enough that I have to seriously worry about locking my brakes :)

Disc brakes with cables work absolutely fine. Yes you're leaving some performance on the table compared to hydraulic, but most folding bikes aren't used for racing.

Cable-actuated hydraulic brakes seem to get good reviews.

[jacquesm]

I've had them, also hybrids (boosted), compared to full hydraulics there is an enormous difference and I would definitely use a cable actuated system over rimbrakes if there was no alternative but only after exhausting every avenue of getting hydraulics to work. I like the option suggested by the other commenter of using an automotive flex hose for the folding part.

[throwaway0a5e]

An automotive brake hose to bridge the hinge will be like $5 per bike. Or just use nylon tube like small aircraft.

[jacquesm]

That would probably work, but you'll have to cook up your own adapters.
