Also had weight issue converting bike into electric with custom lifepo battery, which ended up being almost 30kg alone.
Rear wheel was shot after like 20kms. But the bike was so cheap it wasnt surprising.
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.
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.
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.
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.
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?
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.
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.
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.
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.
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.
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.
"Fatphobic" (because that's what we call social health consciousness these days) rant incoming:
It's been an issue for a while across all facets of life now and no one is brave enough to be the first voice to say "hey, these things literally were not made to support people as heavy as you." In the past year, a horseback riding trail in my hometown had to close because there were not enough customers whose weight didn't pose a serious risk of injuring the horses. A few years ago I had to install a steel support beam in the crawlspace under the master bedroom of a morbidly obese couple. Together, they probably pushed a half a ton and spent easily 16 hours a day on that bed. The framing had become so sunken that you could see the subflooring through the gaps that appeared between the flooring.
Just the other week my roommate invited an old school friend over, the guy probably weighed about 300lbs at 5'8" and broke a stool (Lyra by Magis, very nice, one of my favorites) in my kitchen. How anyone can be that big and so unaware of the strain their weight is putting on the things underneath them is beyond me.
But bigger people deserve to be able to bike too! It’s just the reality of the world we live in, plus many people have genetic issues that make it fairly difficult to lose weight. They shouldn’t be locked out of basic things like being able to survive without a car. I admit horses are a different story because they’re live animals, but bicycles are human-made and can and should be designed to handle more weight, especially with how many people are bigger.
Deserve to bike and "deserve to force bicycle manufacturers to make mass-produced models that super serve the super-sized even though they're a significant minority of the actual and probable global customer base" are very different things.
If you want a bike for someone 300+, get a used, big steel frame and start assembling. Same for weight weenies the want bikes as light as a feather: customization is on you. Mainstream, pre-assembled bikes are going to be made for the majority of people that are likely to buy them, because otherwise they won't sell.
Again, to emphasize: AT EITHER END--super comp or super weight--bikes are specialized (not the company) bicycles that require parts selection and piece-by-piece assembly. It's not "unfair" to morbidly obese people anymore than it is unfair to someone that wants a super light bike or a super durable, weight-bearing, bike-packing ride.
My friend is 6'5 and all muscle, idk how much he weighs but it's got to be a lot. He had to build a bike from scratch as well. He would pop spokes and mess up frames. It's not about fat it's about weight. Less than 2% of the population in the United States weighs more than 300 pounds, and I imagine only a fraction of that fractional subset of people intend to ride a bicycle.
Also, "custom" does not necessarily mean expensive. It just means building it up piece by piece. Many people who have very little money but want a decent bike also build "custom" bikes from used parts, because you can slap together a decent bike from good used parts rather than spend the same amount on a Walmart special that breaks apart in two months.
I agree that there should be options for bigger people, but that doesn't mean that there shouldn't be bikes as light and high-performing as possible made for those who can use them, and if that's the focus of a given manufacturer, that's not an ethical issue. It's just their specialization, and there's plenty of room for other designers to focus on bikes for heavier riders as that market becomes viable.
Everyone deserves to ride bikes, and bike designers deserve to focus on the types of bikes they want. 7-foot NBA players deserve to be comfortable in cars, but it's not Ford's fault or responsibility that finding a car is more difficult for them than for those between the 10th and 90th height percentiles. No less unfortunate, but changing the design of all cars or expecting app major manufacturers to design for outliers isn't necessarily a solution.
I agree with most of what you said but not It’s just the reality of the world we live in, plus many people have genetic issues that make it fairly difficult to lose weight.
It’s not just the reality of the world we live in. People were not this fat 30 years ago, let alone 50 or 100 years. And it is something we can change, if we cared to.
“Genetic issues” are too much of a crutch or a lame excuse. Yes that makes it more difficult, but it doesn’t make it impossible or justify not trying to get to a more reasonable weight.
But there absolutely should exist a segment of bicycles for almost every range of weights.
I got put on Concerta as a kid and I ended up gaining quite a bit of weight very quickly. You don’t really notice these things when you’re living in that body 24/7. All of a sudden I was not able to fit in my favourite hide and seek places. Just another perspective since you said you couldn’t wrap your head around people who don’t know their own weight.
Yeah I mean even if you're someone who feels that being fat is not their fault or something to be ashamed of, nor are the laws of physics and limitations of structural integrity someone else's.
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.
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.
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.
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.
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.
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 …
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.
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.
Generally 120 or 150 kg judging from Sparta and Gazelle materials. That’s about the same as in the article.
Now, our weight distribution is a bit less extreme than in the US, But there are definitely commuters using their bike outside the manufacturer specifications out there right now.
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.
Your MTB wheel set is tested on the standard it's meant for. There's really no reason to test downhill wheel set for maximum weight limit for commuting or road racing because it's not made for that purpose. It's a specialized product for niche sport.
Although true, it isn't the point I'm trying to get across. My view is that weight limits aren't a great metric. You don't have to go for niche sports, the traditional xc/trail bike is what everybody starts with on mtb.
Say this example xc bike has a weight limit of 150Kg. Rider A is at 170Kg buys this bike ignoring the limit and just rides smooth local fire roads for some excersise.
Rider B is young, athletic 70Kg build. Buys this SAME bike and goes on rides with friends that know all the fun trails. Rider B is getting faster and stronger, and the bike starts to show it's limitations.
It's clear which bike will fail sooner. Weight alone doesn't matter, and both riders are using the bike for it's intended and designed purpose.
Manufacturers cannot reliably slap a max weight to their bikes because of all the other factors involved. And if they do, it will be way conservative to avoid getting into legal trouble.
Regardless, weight loss happens in the kitchen not in the gym. Studies show that compensatory eating from exercise, especially if you're overweight, can actually lead to weight gain. I.e., you should get your diet under control before you start fooling yourself into believing you can exercise yourself skinny. That will only lead to frustration. And that's over and above the real physical toll exercise can take on the joints and organs of the morbidly obese.
That's in an ideal world though. For some people, just walking a mile throughout a day qualifies as exercise because they are so sedentary. But if people are serious about getting healthier, they need to examine and change their diet regardless of how "addictive" food is. Many things are addictive. That doesn't mean that you shouldn't stop doing them or that their addictive nature excuses continued use.
If you're addicted to a harmful substance (and I think we can count junk food in that category), than, like any other addictive substance, you likely need counseling and, ultimately, you need to stop the addictive behavior.
It is difficult to maintain a calorie deficit, but it is also impossible to gain weight while in one. There are good calories that provide a lot of other nutrition, and bad calories that offer nothing to your body, but that doesn't undermine the fact that you can't gain any long-term weight as long as you keep your total calorie intake (good and bad calories) below your calorie expenditure
