Where Discs really shine is in winter riding. With just an inch of snow you will not have any braking ability with rim brakes. I run a studded front tire on my swift and as yet have not put a new fork on to add a disc. My winter bike was stolen two years ago and I'm now riding in the snow. I had a wonderful short ride this morning with 2" of fresh snow. A little slower but the silence and feel is really sweet.

I've always had rim brakes on my folding bicycles - until our customised Vostok-Bromptons.

V-brakes with suitable pads offer superb braking with an ability to cope with fat tyres. Unfortunately not an option with our Brompton.

Dual pivot road calipers tend to restrict tyre width due to their design.

Disc brakes were optioned as: we will be touring very mountainous country; and the Brompton use small 349 wheels - compared to our previous mini-velos running 406. I was concerned that excessive braking may overheat the rim and affect the tyre/tube due to the significantly smaller braking surface area. Overheating is more common in travel tandems running 406- hence their use of drum brakes.

Disc brakes also cope better with a "buckled" wheel - as may be experienced whilst touring. This capability has saved me from having to walk a bike on a few occasions.

The downside: complexity, cost, increased folded width, extra steps when air transporting (I remove discs).

Not a fan of disc brakes on a folding bike mainly because I suspect I would more likely damage them. However given a choice between mechanical disc and hydraulic unless very high end hydraulic I would go for mechanical for their simplicity and ease of adjustment and maintenance. Drum/roller/coaster brakes are for me the best choice on a folding bike, everything else seems a compromise of sorts for a folding bike. However I feel as the wheels get smaller and the disc clearance to the ground gets less then they look far less desirable. I can't see a problem on a large wheeled folding bike unless somehow the fold risks damaging the discs. The clearance of the discs to the ground with kerbs, obstructions, potholes etc makes the bike below not very desirable for me. I think I'd have a high chance of damaging those discs fairly soon in riding before I even think about the issue of loading and unloading the bike from my car, lifting on a train or storing in a cupboard/wardrobe with other items.

I remember hearing a bicycle shop sold a lot of replacement discs although I guess in fairness that was a while ago and probably pretty much exclusively mountain bikes. May not be such an issue with road and hybrid bikes using disc brakes. Saying that some of the disc rotors you see on road bikes look very thin and weak more so than on mountain bikes. Seems like they have used less material in the structure of them to keep the weight down. It looks like I could bend them with one small finger. I guess the quality and strength of the rotors is an important factor in the debate. As with most things on bikes there is a large price range between not fit for purpose pretty much and extremely well engineered.

Disc brakes are good for big hills, especially touring with a load. They do make packing more complicated. Sometimes you may consider removing the discs fron the wheel to fit everything into a suitcase.

I personally like cable pull disc systems more than hydraulic. Easier to keep tuned and service on your own mainly.

Dahon has 3 current bikes with disc brakes.

Full suspenstion Jetstream (or Jet in some markets)
24" IOS D9. (Prior S9 had hydraulic brakes)
Visc D18 Disc version.

Nice rides I feel.

On Dahons the front hub measures increase from 74mm to 100mm in Disc Brake bikes.

Upgrading to disc brakes is an interesting subject for the future.

That said V-brakes are tried and true.

I want to learn more about the Origami Gazelle

Do the Gazelle or Dragon fit easily into your large suitcase? Nice looking bikes!

Tradeoffs around the disc brakes vs V-brakes (since that is the subject of the thread). Nevermind. Pretty much answered in the thread up and down.
Curious still about packing discs in your suitcase though.

Happy Holidays Paul and everyone!

I don’t recommend packing bikes with disc brakes because the discs are susceptible to damage when the wheels are removed from the frame. You can do it, but you need to remove the discs from the hubs to protect them. I will try to fit them in he next week and post photos.

I was wrong! The Gazelle fits nicely into the case, and it is not that difficult to protect the discs. I will post below

Trade offs: disc brakes work well in all weather conditions and they apply the braking force nearer the axle for better control. Disc brakes weigh a little more (maybe 10 ounces) and they cost more. Good quality disc brakes adjust easily and stay adjusted (Walmart disc brakes can be a nightmare), disc brakes donít wear out your rims and generally wonít drag if your rim gets out of true. Rim brakes are lighter, allow for a narrower front hub, are cheaper, are still easy to adjust.

Ok, the Gazelle fits nicely into our airline-legal-sized case. You just have to remove the rear caliper (two fasteners) to be able to fit the front fork into between the rear dropouts to avoid issues with the calipers. Not difficult at all.
