There is one major issue with this article:

Yet, many bikes and bike equipment are still manufactured with only the other 26% in mind.

No. They are made with the majority in mind, since the European and Asian bike market, where significantly fewer people are overweight or obese dwarve the American market.

Projected North American bike market revenue (2024):
$10.44 billion

Projected European bike market revenue (2024):
$27.89 billion

Projected Asian bike market revenue (2024):
$42.13 billion

On an international market, if you don't matter enough you won't get special treatment.

Just imagine if 74% of Luxembourgians decided that their smartphone must have a USB-A port, as an essential requirement. How many major manufacturers would accommodate them instead of continuing to sell "normal" phones? Sure, they could put a USB-A port onto all phones globally sold, but why bother? It's more expensive and nearly nobody outside of Luxembourg would want that feature.

Edit: Source for the numbers (you can switch the displayed region)

where significantly fewer people are overweight or obese

Hey, not sure if you're getting your numbers from the article, but you may want to double check.

40% of Asia is overweight or obese and over 50% of Europe is overweight or obese, with USA at 75%. (Sourced from WHO)

Also, just an aside: the USA is the smallest of these three by population, so the total number of overweight or obese people in Europe vs USA (240-250M)is fairly close even though the percentages are higher.

[-] chicken@lemmy.dbzer0.com 15 points 4 months ago

A good point, but from the article it sounds like the demographic for which this would be a problem is 300lbs+. The proportion of people meeting the criteria for being overweight is in the same ballpark, but I wonder if maybe there's a more skewed distribution of people who are overweight enough to exceed the safety margin of a standard bicycle.

[-] Cort@lemmy.world 11 points 4 months ago

I think it starts to be more of a problem around 230-250lbs. Like they mentioned in the article, the bikes are often listed at a total weight capacity, meaning rider + cargo, with most brands at or below 300lbs. If the rear rack is meant to hold 40lbs and maybe 5lbs of accessories and water bottles then add 20lbs for a front rack/panniers; your getting into the close to the rider weight limit by being anything more than a little overweigh.

[-] isaaclyman@lemmy.world 8 points 4 months ago* (last edited 4 months ago)

It’s worse than that, even. Some brands (like Tern) go by gross vehicle weight, meaning rider + cargo + bike. And their most popular bike is 75 pounds.

It’s not as much of a problem for Tern specifically because their bikes are rock solid (I’m very big and tall and don’t have a problem with mine) but still a confusing way to measure.

[-] BastingChemina@slrpnk.net 16 points 4 months ago

I think the article is mostly advocating for the weight limit to be on the technical specificationd of the bikes, which seems a fair argument to me.

[-] Showroom7561@lemmy.ca 43 points 4 months ago

I honestly applaud anyone who wants to get on a bike, especially if it's to improve their fitness.

Bike frame weight limits are only one thing to consider. Wheels and tires have weight limits too. And some bikes have a higher center of gravity than others, so weight up top would be very unstable.

I would think (hope) that anyone who is over 220lbs would consider a custom, steel frame bike that is built specifically to handle the extra weight, and not rely on what the weight limit on a website says.

Also, people have to realize that the "weight limit" of a bike can often include other things that the rider might be carrying on their bike. Cargo bikes often have several weight limits depending on what you're looking for, but even those have their limits.

Side note: this was a problem in the e-scooter world, where you'd get people who would be at the upper limit of the scooter's weight limit asking if it would be safe for them to ride. Well, the frame might support the weight if it's not in motion, but the motor likely can't push that weight for very long, and certainly not up hill.

[-] knexcar@lemmy.world 21 points 4 months ago

A custom bike sounds expensive, I really wish there were more east-to-buy prebuilt options. Fat people are pretty common, they’re not a rare body shape or disability that should require a custom bike. And I do wish higher weight limit tires were more common, I’m not overweight myself but I sometimes heavily load my electric bike with cargo (and a trailer that pushes down on the rear axle), and occasionally I have problems with spokes breaking already. Bikes that can carry toddlers are becoming common fast, I wish heavy wheels were more standardized for both heavy people and cargo bikes.

[-] sploosh@lemmy.world 25 points 4 months ago

Fat people are pretty common, they’re not a rare body shape or disability that should require a custom bike.

Bikes are, in general, designed to be as light as they can be for their price point. The reason behind this is that a lighter bike is less weight to move, meaning for the same effort one can potentially go farther or faster than they would be able on a heavier bike. So when a company is designing a bike, they think about the person they believe will buy it and design a bike that will support that rider.

Heavier people weigh more, obviously. Larger loads require more structural strength. Making a bike that can carry a 300lb+ person without breaking involves a redesign if you initially designed for lighter loads. Similarly, building it requires change to your manufacturing processes.

People who have health problems due to their weight, in general, do not buy as many bikes as people whose weight does not negatively impact their health. A company isn't going to go an make a big production run of an expensive product if they don't think there's a market for it, which means it becomes a custom job to get one done.

Want cheaper bikes that can handle 300lb+ riders? Do a kickstarter and see how many customers will put down dollars.

[-] Showroom7561@lemmy.ca 16 points 4 months ago

A custom bike sounds expensive, I really wish there were more east-to-buy prebuilt options.

Yes, it can be expensive, but being obese is expensive. Some people have to go out of their way to buy "big and tall" clothing (at a premium), special beds or chairs, modifications to their car, etc.

Fat people are pretty common, they’re not a rare body shape or disability that should require a custom bike.

Fat people may be common, but heavy-duty bikes are not. For a bike to be stronger, you either have to sacrifice on cost, the weight of the bike, frame materials, or hard-to-find/custom gear.

It becomes a problem when someone is looking for a cheap bike, because none are going to be built to carry an enormous amount of weight.

And I do wish higher weight limit tires were more common, I’m not overweight myself but I sometimes heavily load my electric bike with cargo (and a trailer that pushes down on the rear axle), and occasionally I have problems with spokes breaking already.

They are... for a price. You can get tires and wheels built to handle more weight, but you'd have to pay a premium for them, and be willing to sacrifice their size/weight.

You also have to be realistic of what you're getting. If someone weighing 300lbs wants to get a small folding bike, they aren't going to have much luck with anything.

I fitted new wheels on my MTB turned touring-capable bike, and had to get 36 spokes and very beefy schwalbe tires to accommodate the load. I spent a lot more than someone who doesn't have to worry about carrying weight.

I wish heavy wheels were more standardized for both heavy people and cargo bikes.

They will be. E-cargo bikes in particular have really jumped in popularity, and that will be followed by cargo-specific tires, wheels, and accessories.

But to circle back to the original article. Yes, weight limits and all relevant specs should always be listed and easily available. I personally hate having to dig through stuff to find something as important as torque specs for bolts, as an example.

Custom bikes are actually cheaper if you have like $50 worth of tools.

[-] Please_Do_Not@lemm.ee 10 points 4 months ago

Yeah I just don't see the solution that a lot of people are pushing for. Should everyone's bike be heavier because some people need them reinforced? And should scooters not be popularly used until motors than can push 3x the weight are common?

Having bike and scooter options available that work for everyone should be a goal, but criticizing existing models doesn't make sense to me.

[-] Showroom7561@lemmy.ca 8 points 4 months ago

Yeah I just don’t see the solution that a lot of people are pushing for.

I think it's two-fold.

Yes, in fairness to everyone, manufacturers need to post weight limits (and all other specifications) in an accessible way.

That said, prospective riders should realize that what they need will likely be at a category/size/weight/price they weren't expecting.

[-] bitwolf@lemmy.one 8 points 4 months ago

I don't consider it far-fetched for a manufacturer to list the lowest approved weight of all the components as the bikes rated weight.

Or even certify the frame separately so they have a practical and theoretical weight limit of the bike.

[-] KillerTofu@lemmy.world 21 points 4 months ago

With 74% of adults in the United States classified as being bigger-bodied individuals by the CDC

I’m sure that’s the CDCs preferred term.

[-] Demographics 15 points 4 months ago

I know everyone likes to be mean, but let's be creative here: It's not just the stereotypical fat American. Look at our athletes and body builders, a lot of people who could possibly be in these terms are healthy by all metrics; some Americans are just taller and more muscular.

I'm not downplaying the obesity epidemic, but I feel like a more generic term is appropriate here.

[-] KillerTofu@lemmy.world 15 points 4 months ago

It’s rare for bodybuilders to push over 300lbs in weight, even supplemented. When talking about body mass, sure BMI is just an indicator and not a diagnostic measure.

Of the 74% mentioned in the article, a small percentage of that would be the athletes and other genetic outliers.

[-] SuiXi3D@fedia.io 21 points 4 months ago* (last edited 4 months ago)

I got an e-trike that lists its weight limit as 330lbs. However, the seat post only supports 220. So one bent seat post later, I’m looking for a new post that can support my fat ass and I’m coming up short. Help?

[-] domdanial@reddthat.com 8 points 4 months ago

Solid aluminum bar is pretty cheap, if you have any sort of tools to cut it to length. I don't know what your clamping/attachment method is for your bike.

[-] SuiXi3D@fedia.io 4 points 4 months ago

Was hoping for something premade. I’ve got a Lectric XP Trike.

[-] domdanial@reddthat.com 3 points 4 months ago

Yeah, I haven't seen anything for a more sturdy seat post. Im willing to bet you could find an aftermarket seat and post though, because it looks like it's a pipe-in-pipe attachment to the rest of the bike. As long as it's got the same diameter.

Or fill the stock one up with JB weld or something. Give it some extra stiffness.

[-] qjkxbmwvz@startrek.website 17 points 4 months ago

I just checked, and the company website page on my relatively high end carbon bike has a listed max weight (rider+bike+equipment) of 120kg. Easy enough to find on the page.

That said...were I close to that limit, I think I'd opt for a steel bike, or maybe titanium if I have the money. Carbon is amazing but its failure mechanism isn't pretty.

[-] isaaclyman@lemmy.world 16 points 4 months ago

6 feet 6 inches, 270 pounds here. I spent a couple of weeks tracking down weight and height limits when I was looking into bikes. It wasn’t easy, and it should have been. I don’t expect every model of every bike at every manufacturer to cater to me, I just wanted to find one goddamn mountain bike I could safely ride.

I ended up with an eMTB made by Specialized, and paying more than I wanted to, and calling the bike shop to see if they knew the weight limit because the documentation on the website was unreadable without an engineering degree. (I exaggerate, but it was bad.)

But in the meantime, I spent a lot of time having bike brand website “sizing quizzes” do the surprised pikachu face when I entered my height/weight: https://toot.cafe/@isaaclyman/112714856810902224

[-] MintyFresh@lemmy.world 8 points 4 months ago

I'm 6 ft 6 myself and much fatter by the sounds of it, and I feel your pain! My biggest beef is when they say something is "appropriate for anyone over 6'!" And the other size categories are broken down in 2" intervals. Like a bike built for someone a half foot shorter than me is gonna work. I haven't had a bike that fit since I was a child and shorter.

Another slightly related rant id like to rage is furniture in restaurants. Seriously child sized. I went out last night with friends and couldn't get my legs under the table. Everyone had a good time but me who's ass back and knees suffered.

Fuck being tall. If anyone ever gives you the choice be 6ft even.

[-] isaaclyman@lemmy.world 6 points 4 months ago

Yeah, being tall sucks. If anyone out there wants to be 4 inches taller, I’ll be your donor.

Honestly if airplane seats were less like medieval torture devices and T-shirts didn’t shrink in the dryer, I’d be all right. I can deal with bumping my head on things and getting the same questions/comments every time I meet someone new. But being constantly reminded by ordinary objects that I’m not considered part of the bell curve? Rude.

how well do Dutch omafiets and Japanese mamachari fare in this regard? so much of what’s available in the US seems aimed at sport (racing or mountain biking) rather than the utility and daily commuting focus of Europe and Japan …

[-] Please_Do_Not@lemm.ee 9 points 4 months ago* (last edited 4 months ago)

Well only 15% and 4.5% of adults are obese in the Netherlands and Japan, respectively. Nearly 50% in the US are. I don't see any reason why the few design differences between a classic American hybrid or road bike and either of the types you mention would drastically affect their weight capacity, but it's also just much less of an issue in those countries.

[-] Showroom7561@lemmy.ca 6 points 4 months ago

Those bikes are often steel, and likely could support more weight, but not by much. Wheels and tires have their limits too. I wouldn't consider anything but a custom bike or higher-end steel touring bike if I weighed more than 250lbs.

[-] Tudsamfa@lemmy.world 3 points 4 months ago

mamachari

I picked a random bike on their website and it had the exact same problem the article is about: it doesn't list a maximum weight for the rider.

I guess this is one situation of privilege I and a lot of lightweight people experience: Of course the bike will support my weight, I don't even have to check. Meanwhile people over 200 pounds are told to import bikes and 300+ people don't even get any certainty that an import will support them.

[-] FartsWithAnAccent@lemmy.world 12 points 4 months ago

Obesity aside, it's important to have the weight limits clearly defined just for hauling stuff alone, but I applaud anyone who gets on a bike and rides. We should be encouraging overweight people to ride instead of trying to shame them.

America has a serious food problem where shitty food that is horrible for you is far more affordable and accessible for man than actual proper food that will nourish you. As a result, obesity has become a massive problem. Cycling won't fix everything but it can help a hell of a lot!

[-] Akumakins@lemmy.world 9 points 4 months ago

I'm still pretty new to riding bikes as a adult, but wanted to share my experience in hopes it helps folks:

Im 6' 330 lbs and ended up getting an aventon aventure eMTB. It's held up well over the 400 miles I put on it, but I definitely notice the brakes going quicker than advertised with all the hills near me and my size. I'm sure it won't last forever, but I'm expecting to get under $1 of initial cost per mile ridden, which felt worth it to me as a 2nd car alternative.

I've been looking into a company called Clydesdale also to plan for bike 2.0 in a few years. They advertise titanium framed bikes made for very tall folks. I never used them myself, but they may be a good option for folks willing to pay 5k for a bike.

[-] litchralee@sh.itjust.works 8 points 4 months ago* (last edited 4 months ago)

I agree that there exists a problem with unmarked weight limits and this affects larger riders, but I think the author's proposed change will not be sufficient to increase the availability of bikes with higher limits. The author writes:

My proposed solution, which I presented recently at the National Bicycle Dealers Association annual meeting, is to add the weight limit to the geometry spec sheet for every bicycle next to the standover height and reach

Publishing a spec is (and ought to be) a minimum obligation by a manufacturer, since the consumer has no way to compute these values on their own. So I agree with that. The problem is that unlike the standover height or wheel diameter, the weight limit is artificially constrained downward by limits of mechanical modeling software or destructive testing, and artificial limits like how much product liability the lawyers are willing to permit.

If bike manufacturers have a robust regime for testing up to 136 kg, then testing beyond that would require new processes and test equipment, all of which cost money. So a manufacturer that complies with the author's proposed rule would simply publish the 136 kg and call it a day, foregoing a supposedly narrow market segment. So a frame that could have supported more weight has been marked lower than it ought to be, while fully complying with the proposed rule.

We run into the crux of the issue: economic demand for higher weight limit bikes is not perceived as being significant. So few will supply that market. Which means there's little demonstrable demand. Which keeps the supply small.

If this sounds familiar to this community, it's essentially the same problem as with micromobility from the regulatory aspect in the USA: only the automobile is viewed as "serious" transportation, so everything else is just for recreation and doesn't warrant its own infrastructure. So no separated infrastructure is built. Which keeps viable options like cycling and roller-blading from becoming popular. Which reinforces the perception as not being a "serious" mode of transportation. Repeat ad nauseum.

There are no easy answers to such structural issues, but we can take inspiration from the popularity of ebikes in the past decade: growing from a niche of motors crudly strapped to conventional bikes, ebikes nearly single-handedly transformed the perception of bikes overall, showcasing their strengths in sense urban areas like NYC for delivery vehicles: fast, nimble, cheaper than an automobile. From there, they became popular not just for existing cyclists, but new riders, some whom haven't been in the saddle since childhood. New markets opened up, and combined with a touch of enabling legislation, ebikes have taken off.

I think the author touched upon the niche that could drive higher weight limits, and that would be cargo ebikes. That space is growing as ebikes -- a bonafide transportation answer to American sprawling suburbs -- become more readily accepted, and more fairly-wealthy suburbanites take up cargo ebikes to move the whole family.

Of course, this is going to be a slow process. And it will take a while for cargo ebike prices to come down from the "luxury" range to an "affordable" figure. But I think that's the crack that will grow to break the ice.

As for whether the demand should even be met, I saw that a different comment remarked that today's bikes aren't built for larger people, since in the past, most people weren't as large. And that's factually true, but it doesn't justify not fulfilling a market in the here-and-now. Nor does it support the idea that nobody in the past was over 100 kg (220 lbs).

A quick web search shows that some NFL players in the 1930s Hall of Fame were over 100 kg. If these folks wanted to ride a bicycle with any amount of cargo, it probably would be as difficult to find a sufficient bike then or now. So the problem has always existed, but the degree to which it's a problem has changed to include more people. That should be a reason to encourage more bike varieties, not to shut down the very idea that larger bikes ought exist.

As another commenter notes, these people deserve bikes too.

[-] JohnEdwa@sopuli.xyz 8 points 4 months ago* (last edited 4 months ago)

With bicycles one major hurdle is that they are assembled out of a bunch of components sourced from multiple different manufacturers, meant for different uses. So while you can create a bicycle frame that handles 150kg fine, can you find a saddle, seat post, suspension fork, hubs, wheels, tubes, tires, cranks etc that all also support 150kg? Or will one of those parts be cheaply sourced as only promising 100kg, so that's what the label will say in the end.

[-] litchralee@sh.itjust.works 4 points 4 months ago* (last edited 4 months ago)

Component-level weight ratings are indeed lacking right now, although I will note that the author appears to be proposing a frame-only weight rating, presumably because while all other parts of a bike can be replaced, the frame is at the center of a bike, setting aside Ship of Theseus considerations. Replacing a frame is virtually equivalent to building a new bike, after all.

Of course, a manufacturer of assembled bikes should publish an overall weight limit for the bike as-assembled. But still, it might be nice to know that the frame specifically is overbuilt for that particular assemblage, meaning it has capacity that can be utilized with the appropriate upgrades.

You're absolutely right that just rating the frame alone won't necessarily result in broader marker supply, but it's certainly a start. As I said, there's a vicious feedback cycle and the way to break it is to find a niche and grow it. Perhaps mandating a frame-only weight rating will spur lawyers to require all weight-bearing components to also have weight ratings as legal cover, or something like that. Such a limit might be low, though, but is still progress.

[-] hawgietonight@lemmy.world 5 points 4 months ago

Weight limits on performance bikes are total nonsense. Probably are there just to comply some law. A pro enduro rider weighing 20kg less than me would destroy my setup any day.

I find hard to believe a traditional 26er with 36 triple cross spoked wheel from a reputable manufacturer can't hold up to any rider capable of moving on their own and sitting on a saddle any amount of time.

Unless they are heading to Whistler's a-line

[-] Evil_Shrubbery@lemm.ee 4 points 4 months ago* (last edited 4 months ago)

This is why I'm so pro regulations - a simple (predetermined) fact sheet that every bike sold needs to disclose.

And as society and needs evolve keep the regulation alive and modify it accordingly.

Ofc the industry is gonna bitch about it like it's the end of bike industry for good & try to gift it, but after a year it will be normal, costs negligible, profits the same - but the market more transparent.

And for most things, like this bike thing, it can be super a simplistic requirement, no need to be to the kg exact, it could be defined by categories of 50kg even. However the weight class should mean under a certain higher-than-usual stress on the constriction (bikes mostly arent meant to be used stationary).

But yes, manufacturers should test their products to the breaking point, not let costumes do it (unless it's Bethesda, then it's just expected).

Also - I've recently helped a 130kg friend get an office chair, nothing too demanding I know, but I noticed how weight specs, if even provided, seemed a bit random. Even (separately provided) piston specs were different for what seemed the same model.
