I'm interested in folding bikes. This is a great device if you can afford the price tag $1300+ there is also the a bike. http://a-bike.co.uk/product-category/bikes/

The difference between the A-Bike and the Kwiggle is: With an A-Bike you can make max 12-15 km/h, with a Kwiggle you will ride at relaxed 25 km/h and can do even much more.

What am I missing. I looked at the Bromton and it’s ~$3,800 or roughly 1/12 of the Decathlon.

Build quality and longevity. After five years of daily use you will be able to resell your Brompton for 80% of its initial price, while I would guess you would be lucky to get more than $100 for your old Decathlon.

The most you can lose out on the Decathlon is those €289, whereas 20% of the quoted Brompton price of $3800 is double that :)

Resale value is important in the sense that you know you are risking at most X, which with Brompton sounds to be €600 — in case you dislike it or don't have a need for it anymore, or are in a need of cash, so the risk you are willing to take is still larger.

Ultimately, as with anything, if Bromptons are really of such a high quality, the best purchase is a used Brompton which you might be able to resell for the same price you got it at. If you really end up using it to the max, you can resell it early and get a new one specced to your liking.

For something you'll end up using daily, the most important thing is quality, and then you should look for the best price next.

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 a…

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...

Thank you for having us here to discuss Kwiggle. I am the inventor and owner of Kwiggle and would like to give you some insights: We have been developing Kwiggle for 10 years and producing Kwiggle for almost 3 years. Every detail has been carefully designed to create a 10kg lightweight folding bike that can even be folded into hand luggage and still go as fast as a normal bike. We have selected materials and manufact…

Question: Why the trolley? Was it an afterthought, or was it not possible to make the bike wheel(s) perform that function when folded?

Good question: The trolley mode needs two features: Rolls and handle. The distance between both should be up to 1 meter. We couldn't use simultaneously the handlebar as handle and the wheels as rolls for the trolley.SO we decided to use the adjustable handlebar as handle and put extra rolls for more trolley comfort. Compactness means short measures all over and that requieres extra rolls.

We are swiftly destroying the planet because people don’t want to look goofy in a small car, and insist on an aircraft carrier-sized truck. And now the same attitudes go for bikes too?!

Why would a larger bicycle be less eco-friendly than a small, intricate bicycle with many bespoke components?

I presume the parent meant that "not riding a bike because it makes you look dorky - and instead riding a car" is less ecofriendly.

Honestly, you'd go flying over the handle bars upon hitting the tiniest twig. I've been riding Montague Bikes for years -- on the other end of the folding bike spectrum. Full-size wheels, rides so much smoother. Doesn't fold down as small but it goes in the trunk of a car or can be carried on the train and that's all I really need.

I also ride Montague Bikes. I'll give my use case. I need a normal, full size bike for most of my riding. However, sometimes I need to put my bike and a few others into the trunk of a car - the Montague folds small enough to make this happen. To have the ability to fold it into vehicles I think there is some added weight compared to other bikes in the frame thickness as it does not have the durable standard diamond frame shape. Also, their flip down bike rack to kick stand is a really cool design.

Folding bikes are better at most of what bikes do; sitting around waiting to be ridden. There’s no good way to store a regular bicycle. All of them are compromises of convenience, security, floor space and weather protection.

Storing vehicles is a social problem not an individual one, given that by their nature people tend to use them to commute, go shopping etc.. (If you live in some crazy jurisdiction that has decided to allocate lots of public space to car storage and not bike storage, then you have a problem, but, uh, don't do that)

The issue with bicycles in public spaces is that they get stolen all the time, even the shitty ones. Folding ones neatly avoid that since you can rather easily store them somewhere safe wherever you go.

What do you mean by efficient?

https://www.schwalbetires.com/tech_info/rolling_resistance : “Tires with a smaller diameter have a higher rolling resistance with the same inflation pressure, because tire deformation is proportionally greater. The tire is flattened more and is “less round”.”

This only means that smaller diameter tires need higher inflation pressure for the equivalent rolling resistance (or rather, deformation). That only becomes a problem when you approach the limits of the material (eg. you can't inflate it any more).

I'm basically sold on your product but I have a question I wouldn't ask even a month ago, though now it feels relevant. Where do you (and your suppliers) source your raw materials from?

The seat is attached to the front column, not to the bottom bracket like on most other bikes (folding or not). This seems to give them a better portability return for sacrificing wheel base than other designs. So that's what they did, apparently: the side views look like on the brink of a wheelie from even the slightest acceleration or incline, all while not getting the CoG all too far from stoppie tipovers. The adve…

That's what you get when you put a mountain biker on a road bike.

"One thing became very clear, and every mountain biker will certainly be able to confirm this: when riding uphill on a racing bike, there is always the conflict between riding standing up, which puts more pressure on the pedals, but you have to keep lifting your weight onto the pedal, and riding sitting down"

This is simply not what riding uphill on a roadbike is, unless you are not used to that position at all. The switch between seated and standing is not done to push harder, it's done to get a bit of variation in position and muscle use. It's not a conflict, it's an opportunity.

Except for those particularly steep slopes where you need to move your center of mass forward to not literally tip over, where it's not an opportunity but the only one. That threshold is sits in the vicinity of 20% incline, depending on size and seating position. This is with a wheelbase about twice as long as the kwiggle, and with a considerably lower center of mass. The author even seems to emit that, in a way, with the suggested tweak "So if you ride the Kwiggle in the mountains, always place the saddle a bit more forward". Good luck descending afterwards if it happens to be a route where you might actually need to brake.

The difference in the climb the author was so enthusiastically describing is simply that he went up more than 10% slower on the kwiggle than on the roadbike (92 minutes instead of 81). If you have ever measured endurance efforts in that game, for example on an ergometer, you will know what a huge difference 10% means.

I mean, nice publicity stunt and it surely was a lot of fun given the weather, but if you want to do that more, get proper equipment.
