But Bike Friday no longer manufactures it: the frame design is so exotic and weird that they had a number of frame issues and failures they had to overcome in the field, and Bike Friday has a lifetime frame warranty. It was a very popular bike, but by the time they had worked out all the kinks the value of them continuing to sell the bike had probably gone negative. The Tikit was just too bleeding edge for its time.
The Tikit relies on a special part in order to be ridden: its hyperfold cable. This cable is no longer being manufactured for Bike Friday and cannot be obtained anywhere. When my cable gives out, and it'll happen sometime soon, my Tikit will probably wind up on the display wall of a bike store. And I'll be searching for something to replace it. But there is no folder even close to the Tikit in sheer engineering prowess, which depresses me to no end as a tech guy. Bike Friday itself replaced the model with the Pakit, a decidedly inferior bike. I'm not sure what to do.
I remember having mountain bikes and the lycra cyclist fashion norms -- like no road bicycle fenders, no basket -- it looks ridiculous in retrospect. When I lived in a 80K ppl town with fields 5 min ride away, and almost never used bikes as a transport -- almost exclusively for leisure.
I can easily fit my folding bike into my car trunk, and very easily fit another one in the back seat. This enables you to drive to the start of a distant cycling route without having to deal with bike racks behind or on top of your car. So much less friction to you just going somewhere and cycling around.
And the small size means I can skip the common bike storage in my complex and store it in my apartment and it doesn't take up as much space as a full-sized bike. In my city, like most major cities, bike thievery is rampant. And if they can't steal your bike, they strip it of parts.
There are some drawbacks though. You can't really use them for hauling heavy loads, so forget bicycle touring or pulling a little trailer for kids or other things. They are also quite slow. And maybe some models have lots of gears, but the ones I checked out (in my admittedly limited search) did not, so they are not suited for very hilly routes.
I got mine used for $200 off FB Marketplace, it was in great condition and ready to ride. It is some generic brand that was sold in Walmarts a few years ago and I could not find any other information on it. I don't really care though. It got me out and cycling again!
Like "Rediscovering the Handcart"

I went through an extended project to make it faster and wound up with a loop handlebar for body position, replaced the wheelset to move from 355 to 406 for tire selection and did the drivetrain at the same time to accommodate a 9-32 cassette. Between the wheels and the sub-11 tooth sprockets I can pedal up to ~26mph instead of ~20mph on the stock setup (good enough) and the low end is about the same. It doesn't perform like a race bike but it's pretty close to an endurance road bike. I do 20 mile rides a couple times a week on it and I've done a couple centuries.
The Birdy is my main bike but I'm a folding and recumbent enthusiast in general. The addition of the fold or moving the cranks in front of the rider means the obvious solution diamond frame doesn't work and I like seeing the creativity of the solutions. I've also owned a Xootr Swift that I gave away to my nephews, a Bike Friday Sat-R-Day folding recumbent for riding slowly in the parks, and a Baron Optima lowracer recumbent that I prefer for rides over 90 minutes.
The Brompton luggage system (its mount and low, forward position) is amazing. Bags can be massive and carry a lot of weight and the bike still feels great to ride.
For pedals, I use MKS EZY Superior Lambda pedals with street shoes. Long but not wide metal platform. And they're quick release. The stock Brompton pedals are clever, but not awesome for long distance or hammering. I've spun SPD clipless pedals on for spirited riding and those are, of course, a joy.
The Brompton design is genius but if I could improve one thing, it would be to allow slightly wider tires into the frame.
I'm 15 years into owning a Brompton and I know I'll never get rid of it. and I'm still finding useful and/or hilarious new places to take that might otherwise not allow for a bike. e.g. I had to ride a cargo bike across town for service last week and taking the Brommy in the box so I could ride something home was just so nice
For general use, they are in theory thief-proof because you can take them everywhere with you. The downside is they're expensive so you HAVE to take them everywhere with you. Leave them out and they'll get stolen. For that reason I think the happiest I've been is with a dirt cheap bike in Japan. Didn't even lock it properly (just a key built into the frame) and could park it outside any old shop or restaurant for hours. Super convenient.
Where do I keep it is the problem Brompton’s solve really really really well. And incidentally, if you don’t ride a Brompton, the tires don’t get flat spots because when folded the tires don’t touch the ground.
They are amazing pieces of engineering.
Glad to hear biking has gone mainstream. Don't forget to pay respects to many of us pioneers, some whom survived some who didn't.
Brompton is probably the #1 brand bike thieves will target though, everyone I know who has one never leaves it out of their sight. That's way too stressful for me, I don't want to take it with me in the supermarket or watch over it at the pub. I just got a cheap Decathlon with very low thief appeal.
Besides rides in the city, I take it on long 100+km rides on the road, on gravel, forests, rocks, mountains.
It has taken me on every street of Barcelona and around it many times over. I've had it for 14 years.
Because of the small wheels it's extremely agile and allows you to go really slow without losing balance. This makes it like a sharp knife in the city but also off road on rocky trails, steep climbs, eg. in places where you'd never think of going with a Brompton.
If the trail is impossible, I can just lift it up and climb with it on my shoulder. Or I can fold it and carry it like a bag, on the metro, trains or in the trunk of the car.
As I understand, I'm not the only one using the Brompton as a gravel/mountain bike, so they released the G-line, which I still haven't checked out, but it's on my bucket list.
If I were to write one eulogoy for a piece of equipment in my life, the Brompton is definitely it :).
Still, even though I've had it for years, I always feel awkward about bringing it in to a cafe or similar, and almost never do it.

The only "gotcha" is how you deal with luggage. I've used a seatpost rack, but I've also had a seatpost rack fail on me one time.
It's his bike, he loves it, it's not an unbiased independent review.
Tokyo also has a couple of great Brompton shops for maintenance and parts.
stealing this. you will be paid 0 in royalties/licensing
Folding bikes always seem to push engineering into very unusual directions compared to regular bikes.
The biggest downsides are speed and climbing ability. 80k or so has been a reasonable max distance on tour (I've done one 100k day, it was long) and I wouldn't take it to the Alps.
Like the OP, I run Schwalbe Marathon Plus which has been good. But I have had one catastrophic puncture after riding over a particularly nasty piece of glass that cut straight through the tire. After that I bring a folding backup tire.
It paid for itself in saved fuel and parking fees in the first year I had it.
Then again, taking the front wheel of my road bike takes an extra minute. Then i can put it on the train as well. That’s when I start questioning my decisions no matter whether I took the foldable one or non foldable one.
What are the more legitimate reasons for little wheels on bikes? I guess the goal like with this one is to have the least amount of bike as necessary?
I have upgraded the Tern. The original FSA crank would come loose and so I replaced it with a Shimano 105 part which required a Wheels Mfg 386 EVO Adaptor. I've never had a problem with it since. I also replaced the front derailleur with an SRAM Yaw which is just perfection.
It's great out to about 20 miles and you can't go up anything really steep because the shorter wheelbase just pops a wheelie. Tires and tubes are hard to find. But it's an awesome bike to have around.
Maybe it's just my experience, but every folded bike I've seen in the wild looked more or less like a bundle of bike parts, with bits sticking out here and there. You'll never look at a folded bike and think, "Hey, what's that?", because it always looks exactly like what it is.
It seems like there's something about a bike's geometry and mechanism which doesn't lend itself to symmetry and easy compaction.
As TFA notes, they're allowed on trains even during rush hour when full-size bikes are not. They fold effortlessly; folding and unfolding a couple times a day at the station is no hassle at all. They ride much like a full size bike, with the exception of the fact that if you pedal through a turn, you're much more likely to strike a pedal into the ground.
The only downside is that the 16" tires are murder on bumpy roads, of which Boston has many.
I’ve been eyeing up Bromptons for years, especially the new G (gravel) line which has 20” wheels up from 16” and chunkier tires (for ride comfort on potholes and rough asphalt, and being able to ride down a trail). But I have no need for one, and they’re not cheap to buy on a whim.
I’d really like to try a Kwiggle folding bike, too, just for fun. The standing-riding position might feel less like riding a bike and more like ‘accelerated walking’. And it folds smaller than a Brompton tri-fold.

Eh?

This one in particular seems quite bad for it. Removing the tire and the folding mechanism designed to make it stable and stationary doesn't bode well for that use case. It really does seem to be designed only to be folded once you're done riding for the day and not intended for transporting it folded except for loading it into a trunk.
They are definitely prioritizing the ride quality over the foldability, compactness, or transportability. Bromptons try to balance it, which for me is a much better package, but for others, probably making too many compromises to ensure that it can meet those requirements.
Anyway one busybody got all uppity. But the driver and rest of the passengers didn't care. So it was fine.
Even in the Netherlands you need to pay €8.50 to bring your bike on, perhaps so the trains aren’t overrun.
Both of my kids have jobs that let out after the last buses run at night, so they take the bus to work and ride their bikes home.
Yes; for example, YouTuber Susanna Thornton does bikepacking and wild-camping on her Brompton: https://www.youtube.com/@susannathornton/videos
and Darin's Adventure Chronicles: https://www.youtube.com/@darinsadventurechronicles/videos
Many other one-off videos exist too under searches for brompton bikepacking and brompton wildcamp.
I know DC bans them and Boston/NYC/Toronto have limited hours, but every other city with a metro seems to welcome them.
I have two Bromptons (a 3 and a 6 speed). Unfortunately, I've also had TWO stolen .. painful. This was years ago now and both were locked up in central London. The second time, locked via a "Kryptonite New York Fahgettaboudit", a good U-lock. An angle-grinder gets through these easily and they're battery powered. I don't believe ANY bike lock is safe now and never lock the Brompton up outside. Great bikes!
In my experience I only got one sharp-object puncture on either of these brands in over 10 years of riding, contrasted with much more frequent punctures on traditional rubber tires.
I think it is possible to make extremely puncture-resistant bike tires with modern materials, without particularly terrible tradeoffs. Materials progress is amazing. Although these are not used, for example in racing, because there is some performance tradeoff in increasing resistance.
I did look a little further on the manufacturer websites, and it looks like neither is literally kevlar, but both are forms of dense cut-resistant polymer meshes (some kind of nylon mesh for the Armadillo and some kind of polyester mesh and polyamide mesh for the GatorSkin).
There's some subtlety about the difference in materials that resist slashing versus those that resist stabbing; my impression is that it's easier to make the latter (you can get extremely effective cutproof gloves, for example for kitchen use, very cheaply, but stabproof vests remain expensive). The puncture-resistant tires are more akin to stabproof vests, which I think is the more challenging property to achieve.
Edit: the top comment (at this time) has a youtube link that shows it fold/unfold in like 8 secs. I can see the genius in it now
As a German it makes me tiny little bit proud that he mentions two German traditional companies. Schwalbe (tires, tubes) and Abus (locks) are basically the default choice other brands have to compete against. The primary competitor for Schwalbe is Continental which is also a German company.
Boomers legislating away a method of transportation they have no use for, combined with a few people using it with little regard or civility, and rental operators so focused on competition that they're unwilling to enforce the rules.
But really, mostly it's the first of the three factors. Thank god they're avid adoptors of ebikes, making those safe for now.
Once you get to the point where a folder is unavoidable, you may as well get a good one, be it Bromptom, Dahon, or whoever. At that point it's definitely a buy-once-cry-once kind of purchase. As much as I love mine, I wouldn't recommend anyone buying one who isn't already really into cycling for transportation rather than sport and doesn't really need a folding bike.
And yeah, the low end of the market is pretty crap, much as it is for regular bikes.
It cost less than half of the equivalent Bromptons bike that's featured in the article.

Where in the world are you finding a not-stolen bike for less than a hundred dollars!?
> none of them come with big gears that I'd need to get home, with sections that can reach 22%
Personally I'd recommend getting a bicycle with a motor.
given the tiny wheels, a chainring that would be "normal" on a 700c 1x gravel bike should be very easy for climbing on a folding bike.

It folds the rear wheel “triangle” (red in the picture) underneath to make it shorter to fit in a car trunk, and quick-releases the seat IIRC. Also has squishy rubber-lump suspension because the rear wheel pivots.
(ICE being Inspired Cycle Engineering in this context).
It has a built in lock that blocks the front spokes, an alarm and I use a $200 chain lock around the frame to fix it to something.
That's a bizarre rule. What was their justification?
Edit: apparently due to safety concerns about their batteries. IMO they shouldn't allow importing/selling them if the batteries are unsafe.
Now partially that's just my laziness and trajectory in life, but I haven't used the bag once (I'm not even sure how to use the bag, it's...complicated?). And the bike was folded only once, when I moved.
About a year later I bought a road bike because I wanted better climbing and longer distances and more comfort. Ultimately, for me the folding bike - while great fun in general, it's fast and agile - was kind of the wrong choice.

I do find my brompton a lot more convenient for the train, though.
It's a wrong allocation of resources where we decide everyone can have 4 empty seats to drive to work but we can't fit 1 person and a bike on PT.
Bikes are allowed basicly everywhere: https://dinoffentligetransport.dk/en/how-to-travel/bicycles-...
Caveat: Bikes are not allowed in the Metro during rush hours 07:00-09:00 and 15:30-17:30. But it is allowed the rest of the time and has 24H service.
You should also know that the greater Copenhagen area is covered by "S-Trains" which are running on dedicated (not mainline) tracks. So metro-ish.
The S-Trains have dedicated space for bikes: https://youtu.be/hgfOxNRAktI

April 19, 2026 3 minute read
I was chatting to a friend about my folding bike and I had the urge to write about it - because this falls in the category of “Things I wish I’d had decades ago”. And maybe I can encourage some others to try these wonderful devices.
Note: I’m 3 months into a new job so blogging has taken a back seat to drinking from a firehose of new domain knowledge, new people, new tech. I’m still playing with AI-assisted coding, but at a slower pace - I do hope to blog more about this when things calm down.
12 years ago I started cycling in London, commuting by train, and I used the bicycle hire scheme mis-named at the time “Boris Bikes”. It was OK but a bit of a hassle - bikes were heavy, payment was fiddly, and often the hire racks would be empty in the morning and full in the evening.
So I followed the advice of other commuters and got this beautiful device - it cost £1000 at the time, a fair bit of money, but on a Ride to Work scheme I could pay this weekly over a year, so it was £4 a week, pre-tax, which made it quite affordable.

It’s a Brompton - and they are a marvellous brand, but I don’t want to just say “Get a Brompton” as I’m sure other brands must be competing in this space - and Bromptons are pricey. So do your own research.
I also (after a couple of annoying flats) got puncture-proof Schwalbe Marathon Plus tyres - and I haven’t had a single puncture since.
And like I said at the start - I so wish I’d had something like this years and years ago. So many years of commuting in Melbourne where I’d walk slowly to a station, or drive to a station and have to cram into busy parking. So many years where my bike would languish in a shed, probably with flat tyres because I only got it out on specific “exercise” attempts.
The folding bike:
I do have a lock - a folding ‘silver’ grade Abus Bordo lock that mounts on the bike. But I only really use it in my home town where thieves are much rarer, or on the very rare case where I want to go in a cafe and there isn’t room for the bike - but only if I can sit with the bike in eyeshot!
I get it serviced every year or two. And after 11 years, it’s had nothing major go wrong - a few cable replacements and the like, but it still has the original frame, wheels, and gears. That’s pretty impressive for 11 years of commuting, though post-Covid I only tend to commute one day a week.
For a lot of people this should be fairly should be simple economics. Our station parking is £10 a day - current Brompton prices start at £1400 - so even ignoring pre-tax schemes and savings in other transport like the underground, a Brompton would pay for itself in 140 working days, or 28 weeks for the poor folks still commuting every day.
Plus I just love the freedom of cycling, and the exercise!
#protip If cycling in one of the supported areas the free Cycle Streets app is marvellous. It uses Open StreetMap data so users can update it when roads change, and lets you choose quiet vs fast routes. People ask me if cycling in London is safe - it’s fine if you use an app like this to avoid the worst roads, and ride sensibly with a bit of care about passing trucks or busses, and (gasp) actually obey traffic signals.
The only defense is storing your bike inside. And then you get karens on the owners corp whinging that you aren't allowed to take bikes inside. Who also don't give two shits when your bike gets stolen from the basement bike storage.
No issues so far. Internet reviews (https://www.decathlon.fr/r/velo-pliant-fold-500/343354/undef...) are quite positive as well.
I've had other Decathlon bikes when I was a kid/teen, I don't recall any issue either.
- The steering column is made of austenitic stainless steel. This .. even provides a pleasant suspension.
- Of course everyone prefers to ride on smooth asphalt. With the Kwiggle you can also easily drive on paved trails. Even cobblestones are relatively comfortable to ride due to the wide tires.
- Is the Kwiggle suitable for longer distances? The physiologically optimal upright posture and the swinging saddle bring each of your muscles in motion, especially in the hip and lower back area. That's why you can ride even better than with any other bike, without tension, pain or signs of fatigue symptoms. We already rode 200 and 300 km (124 and 186 miles) in one day.
That's referencing their ride around the Dutch Ijsselmeer: https://www.kwigglebike.com/en_US/faltrad-extrem
That’s another reason I like the G-line and am suspicious of the “just buy a cheaper folding bike from Ali express with a Brompton style tri-fold”. Idk how much I would trust a bike to take a 100kg person if it didn’t explicitly say a carrying capacity.
It is almost as annoying to others as taking a bike on a bus.
For my $250 deductible I basically just get a nice upgrade to the latest version / a brand new ebike for ~$200 / year.
The peace of mind alone with insurance (and a really nice lock) have fully mitigated this for me. I've been leaving my ~$2k ebike locked up all over San Francisco for ~3 years without it being stolen. (My first beater bike was a POS locked up in my apartments secure bike storage and it was stolen after I owned it for ~9 days so I figured I couldn't double down on the bad luck).
Not any more. A new generation of locks have an abrasive-filled plastic layer that aggressively wears down angle grinder discs. They aren't completely immune to angle grinders, but the better locks will take 20 minutes and multiple cutting discs to defeat.
https://www.cyclingweekly.com/group-tests/wrecked-and-rated-...
For my money, the sweet spot for a Brompton is 1-5 mile rides as part of a commute. Upthread there's links to people who tour on them, which is cool. I've done a 7000 mile bike tour, and I'm not sure I'd trade a touring bike for a folder for that kind of use. If I only had a Brompton, I'd try it, but I own, uh, three (3) other bikes.
Besides the ride comfort from the small wheels, it really does ride a lot like a regular bike. The ride comfort is a huge compromise, to be sure, but if you can ride a bike, getting on a Brompton takes basically zero adjustment. The steering isn't at all twitchy, and while they note that standing to pedal might feel weird, in my experience, it isn't.
The bike is for biking. Of course it is annoying when people bring it on the bus. Or park it in front of my door.
The bike on the metro is not rare because it is annoying. People do simply not have that much tact. It is more rare because people bike those distances and you pay extra on the metro. It is free on the S-Train which also covers longer distances - hence more bikes.
I find bikes annoying in general as well. But that is because they are usually attached to a human.
The point was that it can actually work.
It is not all of nothing. It is an integrated system which actually works.
This was a reply to a comment which claimed that bikes could not work in a large city with a lot of bikes and public transportation.
The same people often argue that bikes cannot work in cold weather.
