micromobility - Ebikes, scooters, longboards: Whatever floats your goat, this is micromobility

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.

Cycling is extremely low impact, and getting exercise on a bike can be a lot easier on the joints than walking or running.

Genetic issues have always been around, but the rise in obesity is strictly modern. Throughout eons of history, people have been at a severe calorie deficit. Your body has many amazing background processes to help you survive famines (your body will try to retain as much fat as possible when starving over longer periods of time), avoid accidentally killing yourself due to excess calorie burns while foraging (your body builds in an automatic efficiency curve into repetitve exercise to conserve calories), and even some genetic changes for those that endured exteme famine conditions, which were passed down between generations after calamities like the irish potato famine, making people more likely to survive. These are great during civilization collapses, but really bite us in the ass in modern times.

However, the rise of ultra processed foods (UPFs) and other calorie dense foods make it extremely easy to take in far more calories than one could ever burn though exercise alone. As more jobs transition from labor intensive (bricklaying, farming, digging trenches, and laying roads by hand and pickaxe), we have created a more sedentary lifestyle at the same time, compounding the issue.

We definitely need to factor in larger people into stuff like biking, but biking alone will not address the root cause of the problem: 1. the proliferation of UPFs coupled with their low costs, 2. a sedentary lifestyle due to cars and office jobs, and 3. the collapse of third places where people can hang out, swim, play outdoor games, sports, etc.

Nip those three problems in the bud, and you improve the health outcomes for generations of people.

Stuff like urban density, lowering the cost of healthy foods while improving signage on UPFs, making it easy to walk, bike, bus, or commute via rail instead of drive, and improve free or low cost social spaces will help. :)

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.

There are no genetic issues which violate the laws of thermodynamics

They're not left out. They just have to purchase the right equipment for their condition.

They have excluded themselves from a segment of the market.

We have to stop infantilizing adults and actually tell grown ups what's actually going on.
