My love of cycling in every form is one of the greatest gifts my dad gave to me. I wish everyone was so lucky to find an activity they were obsessed with that has only upsides.

So much North American rhetoric is focused on hatred of the cyclist - while that bums me out, what bums me out even more is that all the haters are missing out on the wonderful world of cycling. Commuter, road, gravel, mountain, track, indoor, fixed, single speed, folding, electric, uni, cargo, whatever.

I'm gonna go ride now.

Yeah, so weird how biking has become an identity politics thingy. (Not sure if it translates well into English).

I enjoy how it's fast and easy to commute, and I keep healthy. Works even in hilly and snowy Norway. I love how fun it is to use my road bike to go fast and get a good workout. I love my gravel into the woods and the serenity.

This weekend I'm bikepacking 6 hours into the woods,sleeping a night in a hammock, and bike back. Can't wait!

I think this is probably a bit selective, but I understand the sentiment. When I'm cycling I keep seeing awful drivers, and when I'm driving I keep seeing reckless and inconsiderate cyclists.

The awful infrastructure (poorly considered bike lanes, at best) doesn't make it easy to co-exist, either.

But unbelievably ergonomic. A decade ago I rented one to do a week's touring (in France and Switzerland). On a standard bike the first two days of such outings were invariably spoiled by sore butt and shoulders. On the recumbent I knocked off 80km on the first day with not the slightest ache. A total revelation.

Recumbent bikes can promote over flexion of the neck, sometimes. Your neck isn’t neutral, it’s bending forward slightly, like tech neck. That’s not to say a recumbent isn’t ergonomic on the whole, but there are trade offs.

by 7e

5/23/2026 at 8:57:02 AM

Yes, absolutely. Although the neck issue is mostly solved by a 3/4 recumbent (which is what I used), where you are not completely flat.

A potentially worse problem is that recumbents allow enormous force to be applied through the legs (because you can push against the lower back, as in rowing). This is one of their superpowers but you need to be aware of it to avoid knee issues.

The three most avid cyclists I know have all had life-changing accidents on their bicycles - my best friend who introduced me to cycling, my brother in law, and an ex-business partner who I introduced to cycling. All broke their hips and various other bones, and all had to have surgery and extensive rehab. So “only upsides” is perhaps a little too rosy.

My impression is that only people in the bicycling social world believe that. It seems like a victim mentality that they reinforce by repeating it to each other. It's always possible I just haven't seen it, but localities around the country are building bicycling infrastructure, which doesn't correspond to hatred. Where do you see it?

I hardly ever hear someone expressing hatred of cyclists. People who ride obviously like it. The great majority don't care about it - it has little impact on their lives. In cities, on streets I see people honk at, yell at, and flip off cyclists just like they honk, flip off, and yell at other drivers. IME the cyclists generally 'drive' as well/poorly as the automobile drivers.

I do notice that people in spandex racing outfits on road bikes tend to behave with attitude problems toward everyone - pedestrians, non-racing cyclists, cars, etc. They are aggressive and fly by people, often with little margin, at dangerous speeds without warning. It's as if they think they own the road. I was just talking to a bike mechanic I know who brought it up. If people don't like them, it's obvious why.

by mmooss

5/22/2026 at 9:26:52 PM

Some drivers seem to resent the idea that they should have to share the road, or slow down for anyone. Even if cyclists do everything right, they're still slower than cars, and so will present at least a minor inconvenience for drivers.

In Canada the fight has gotten nasty, with governments in Alberta and Ontario putting forward legislation that could remove existing bike lanes.

While I think cycling is great - environmentally, for health, apparently for mental health - bikes and cars don't mix unless they are going approx. the same speed in 1-2 lanes.

Driving a car, bicycles are hard to see - I wouldn't be surprised if visibility in cars is specified to be sufficient to see other cars. Bicycles appear out of nowhere and disappear. Also, cyclists - no better or worse than their automobile counterparts - don't always drive well, and they do things that cars don't such as weaving through small spaces between cars; running lights as if they are pedestrians, but on the road; appearing from sidewalks and other places - really anyplace. I don't object to creative driving - as I said, (city) drivers aren't much different in their way - but it makes bikes unpredictable and hard to see. Then there's the speed difference - bikes much slower than traffic are as dangerous as cars driving that speed (again, except I can see the cars). As long as there's one lane - and if cyclists 'own the lane' and don't let cars squeeze by - it's safe: you can see the bike; multiple lanes and the bike ends up in blind spots, weaving back and forth itself, etc.

I read that in (Belgium? The Netherlands?) the law is that if there is a small (10 km/h?) difference in speed between cars and bikes, they cannot share the road.

by mmooss

5/22/2026 at 11:11:52 PM

Cyclists never do everything right, though. Contested stop signs are a prime example. For every cyclist who stops properly, 99 blaze through with attitude. They are lawless, and cause safety issues for drivers who have to deal with it.

You’ll also see them run red lights, cut off pedestrians, bike right into oncoming traffic (in the same lane, no less), cut across three lanes of without blinking. All in the name of laziness, not safety.

> All in the name of laziness, not safety.

Bikes are different machines with different capabilities and parameters. That they aren't used like cars isn't laziness or even lack of personal safety, but maybe lack of discipline to operate as if it has the capabilities and parameters of a car.

Whatever the motive, it's still dangerous because everything on the road needs to operate in an integrated system of rules. Bikes acting like bikes are unpredictable and using different rules.

But consider the functional differences:

> Contested stop signs are a prime example. For every cyclist who stops properly, 99 blaze through with attitude.

Bicycles both stop much more quickly than cars and take more effort to restart. Restarting from a stop and accelerating to full speed takes energy and wears on tired muscles - and it's not just one intersection but 100 in one ride.

So many times I've seen bikes approach the intersection at moderate speed. That's dangerous in a car - you might need to stop short, you might hit someone or something with your 2,000 lbs metal object which could cause serious harm even at slow speeds. On a bike it's fine - you can easily stop your 200 lbs object, which is also much smaller and more maneuverable and thus avoids collisions easily, and which does little harm at slow speeds.

So the bike does the bike thing, but the car sees a car thing: The car see the bike moving at a normal rate, and assumes it will act like a car and drive right into the intersection. The car stops and lets the bike go first.

> run red lights

At lights, bikes are like (very fast) pedestrians. On foot, at least in the US and many parts of the world, if the road is clear people don't wait for the light, they just cross. Functionally, there's no reason for bikes to do differently. That's dangerous to do in a car because their size and lack of maneuverability makes them big targets and makes accidents hard to avoid, and because they cause serious harm even at slow speeds.

> cut across three lanes of without blinking

Again, bikes are much smaller (able to fit in small spaces) and much moremanueverable. It makes some sense for a cyclist; it would be far more dangerous in a car.

by mmooss

5/23/2026 at 3:18:55 AM

>Bicycles both stop much more quickly than cars

They really don't. Even if you slam brakes and OTB on a bike you will still fly further ahead than a car doing double your speed will travel after applying brakes normally. This is the insanity of running stop signs on a bike - you can't stop, you cannot swerve nearly as quickly as a car and you will take much more damage when T-boned than a car driver would yet you believe it's safer because:

> take more effort to restart.

Yeah, it's not laziness, it's science and shiet.

by pandaman

5/23/2026 at 3:36:11 PM

I think that's just wrong. Bikes stop on a dime (unless going high road-bike speeds), and are much more maneuverable due to their mass and two wheels, and are effectively much more maneuverable because their dimensions make it much easier to avoid objects and fit into the many more spaces than cars can fit in.

by mmooss

5/24/2026 at 12:17:17 PM

In my experience as someone who rides a bike with hydraulic disc brakes and drives frequently, they really don't stop very quickly. I pretty much always am more confident I can stop my car faster. The bike may have a lot less mass but it also has a lot less traction and it's much easier to lock up a wheel and skid instead of stopping quickly, especially in poor conditions/on road paint. I do cycle fairly fast, but this is on a mountain bike on the road, certainly not fast compared to a fit person on a road bike.

I will give you that they're much more maneuverabile and accidents can often be avoided by putting the bike into a space in the road that a car couldn't go into.

by reorder9695

5/24/2026 at 5:01:42 PM

Maneuverability of a bike suffers from the same traction issue. At the speed when you can't plant your foot to pivot around bikes need to go much slower than cars in the same corners to not skid out. Check out descends on any road race, bikes are braking to 20-30 mph in sone corners, which cars pass at full speed. Not to mention that a car can skid fairly easily on either axle, while on a bike very few can get out of the rear wheel skid and the front wheel skid is the game over.

by pandaman

5/24/2026 at 1:39:52 PM

> The bike may have a lot less mass but it also has a lot less traction

I've long wondered about that tradeoff: I've heard some (non-physics-aware) people say that heavier cars/trucks stop faster because they have more traction, but obviously there's a big tradeoff in that equation. As a guess, on a moving wheeled vehicle, 1 kg adds forward energy proportional to velocity, and downward energy constant and independent of velocity? And maximizing that tradeoff would seem to be an engineering goal in order to minimize muscle/gas expenditure. (I'm sure it's well-known but I'm too lazy to look up the details.)

That ignores road/tire and air resistance which are proportional to velocity. And I suppose a key question is the degree to which traction depends on vehicle weight: maybe it depends more on tire and road characteristics, for example. Certainly ice or some kind of low-grip tire would be a big factor.

And that ignores locking up the wheel, as you pointed out.

by mmooss

5/24/2026 at 4:37:55 PM

You could just get on a bike and test for yourself your theory. People who ride bikes tell you they are not good at stopping quickly, perhaps you should ask yourself how you became so knowledgeable without riding?

I'm sure lots of cyclists have anecdata about that hatred. My personal favorite was somebody in a Santa Clara neighborhood a block from the DMV shouting at me to "get off the f***ing road!" Clearly they didn't read the part of the DMV manual that mentions that bicycles must "not ride on the sidewalk"[1], and missed that cyclists are allowed full use of the lane.

I now live in rural suburban Michigan, and even on these rural backroads I have jerks in trucks yelling at me on my e-bike going 20+ mph to "get out of the f***ing way".

Maybe those people do not represent the majority, but it feels like they do, and those actions feel threatening when coming from a multi-ton vehicle directed at a 75 pound vehicle. (Fat-bike ebikes are heavy.) It's also odd to experience this on a rural road on a lake shoreline because isn't the countryside supposed to be slow paced?

I see so many groups that take an entire lane and not even care about the cars behind them - it's easy to understand the frustration of the drivers. It's a knotty problem, I wish we had more bicycle lanes.

by sl_convertible

5/22/2026 at 9:44:55 PM

Obviously I wasn't there for the "taking the lane" circumstances you've seen, but where I live there are very few sections of road where it would be safe for a vehicle to attempt to occupy the lane while a group of cyclists are in it, and cars should be overtaking instead. It's no more difficult for a car to overtake when the cyclists are "taking the lane."

But there are almost assuredly social circles that feel otherwise, that revel at the opportunity to roll coal as they pass a group of cyclists, that joke about running them off the road.

A quick google indicates there have been numerous studies on the subject that seem to support the idea that bicyclists are often reviled by some portion of the population, correlated with those who rely heavily on automobiles.

And, I mean, just scrolling this thread seems to show plenty of anecdotes to support the idea. Seems pretty systemic given the breadth of the anecdata.

I know a bike mechanic who commutes by bicycle (of course) in a city. I brought up bike infrastructure and they said they don't need much: side streets that are too slow for cars going any distance are perfect 'bike lanes' - either there are no cars or it's one lane of slow cars and the bike fits in fine. All they need to do is figure out a route, but usually they can find their way the first time without a map.

LA is notoriously car-oriented, but is it different in that respect?

by mmooss

5/24/2026 at 3:16:06 AM

The secret of LA biking infrastructure is that there are a few small rivers / creeks / storm drains running towards the ocean and sometimes those have bike trails.

Those are really next level because they are essentially bike freeways; completely separated from car traffic (no intersections because the river & bike trail go underneath road bridges).

In fact, it's not only safe and fun, but also much faster than driving during rush hour.

Side streets are often designed specifically to make thru traffic difficult. They have dead ends, weird routes, etc.

I'm a firm believer in cars ruin cities.

Cycling is great. I ride both for sport/fitness and for errands, has a ton of benefits, but I agree with you that the biggest boost is not driving.

Car culture/motonormativity in the US is a huge problem and transit here is severely lacking, cycling infrastructure or other wise (trains, busses, safe pedestrian paths and areas, trams, etc.).

People point to traffic and stress, but there are overlooked harms of car culture we tend to ignore. It's responsible for a significant portion of emissions, and drivers and those near cars inhale a staggering amount of microplastics.

Those who use public transit are less likely to be overweight, less likely to devlop type 2 diabetes, and less likely to have high blood pressure.

Driving needs to stop being an unavoidable default. EVs and self driving aren't the answer either, all the same problems, except exhaust, are present with EVs.

Sadly commuters are the least price sensitive, any gas price which would be enough to convince people to stop using gas would justify buying an electric car. There's also not really an alternative in most American cities as the density prevents public transport.

by boelboel

5/22/2026 at 9:12:22 PM

The low density though is a policy choice, not a geographical constraint. The US is low density because zoning laws criminalized denser housing and mandated excessive parking spaces.

Many smaller municipalities wouldn't be able to afford a drastic uptick in EV usage either, they would be much better off focusing on any kind of public transit to reduce the number of vehicles on the road.

Calgary (Canada) as a similar population density to most US cities and its light rail system has some of the highest per-capita ridership rate in North America, so it absolutely can be done. We just need to stop enforcing car-centric design with our zoning laws and parking mandates.

While I haven't given up driving, the fact that I don't rely on it to commute (granted I work from home rather than cycling) means that when I do drive, my relative frustration is really low. About the only thing that annoys me is dangerous driving... for obvious reasons!

Same situation, working from home, although my city has decent public transport so even going downtown is easier without driving. But now when I need to drive for whatever reason, I get frustrated at having to drive. I'll complain about having to take the car, that why can't they put a bus route here, why is it the train doesn't stop at the station I need etc etc.

Which actually surprised me, when my SO said to me: but I thought you liked driving? When we first met you were always working on your car...

Oh yeah. I did, didn't I? It just kinda happened without me realizing it.

Biking is great. Find an excuse to do it. Two that have worked for me: Commuting and coaching the HS mountain bike team.

From what I've read from this study it seems that constant cycling it what helps most, not just from time to time.

Is this impact above and beyond just the same amount of physical exercise? E.g. jogging?

I think at this stage it is well understood that physical exercise has all these positives, so it would be interesting to know if anyone knows if bicycling is even better, or if it's just more of the same?

Is cycling special I guess .... Like, I dunno using a pogo stick might have the same benefit as cycling, since it's all just physical activity at the end of the day?

There's a few things unique/special to cycling. Injury prevention is a big one, especially vs. running. Cycling is non-weight bearing and avoids repetitive loading and joint impact. (runners average 11 injuries per 1,000 hours vs. cycling's 6 injuries per 1,000 hours).

Because of that though you can ride for much longer durations comfortably than any other high-impact activity so cycling lets you have a much higher total volume of work and greater calorie expenditure without overtraining.

this also means that more cafes are easily within reach of a cycle, where a jog can't quite get you there. plus cycling after a huge sandwich and a coffee is a lot easier than running :)

Do you remember the source(s)? I'm hoping to read more about those and other activities.

> Cycling is non-weight bearing and avoids repetitive loading and joint impact.

Sure. I've also seen at least one study [0] that says the lack of weight-bearing means cyclists don't build bone strength and are more prone to fractures. I wonder if just riding in higher gears addresses that.

> Because of that though you can ride for much longer durations comfortably than any other high-impact activity so cycling lets you have a much higher total volume of work and greater calorie expenditure without overtraining.

Doesn't that also make it less efficient? Running seems to provide more exercise/hour. Again, maybe higher gears would solve that problem.

[0] Sorry, I don't remember the source but I discovered it while looking for something else on, I think, PubMed.

Running injuries: https://pubmed.ncbi.nlm.nih.gov/1439399/

The studies were sport specific, so I'm not sure where to find specifics on other activities too but I'm sure there's data out there for other sports.

> that says the lack of weight-bearing means cyclists don't build bone strength and are more prone to fractures

This is true, especially as you get older, and riding in harder gears don't really help either. There is more torque being applied, but its still a smooth, continuous force there's no impact traveling through to stimulate bone density. You need high magnitude, short duration forces (3x+ body weight) to stimulate that.

By far the most effective way is weightlifting/strength training, which IMO everyone should do, at least 1x or 2x/week. Even runners will benefit from strength training, it's necessary for injury prevention.

> Doesn't that also make it less efficient? Running seems to provide more exercise/hour. Again, maybe higher gears would solve that problem.

Running will get you a higher total energy expenditure, yes. A 45 minute run will be more strain than a 45 minute casual bike ride.

The big difference is total weekly volume. With running, because its such high impact, you have a limit on the weekly volume you can hit before you get an injury or start overtraining. About 5 to 10 hours/week for recreational runners.

A cyclist can sustain 15-20+ hours/week of training volume before you run into the same overtraining or overuse risks.

Cycling is technically less time-efficient on an hour by hour basis, but it does allow for significantly more total weekly volume and absolute calorie burn without overtraining stress or injury.

Gearing doesn't really change the formula at all. Gearing changes which system is being used cardio vs. muscular fatigue. If you shift into a harder gear, but your cadence drops proportionally, your power output remains identical. But mashing (a lower cadence) a harder gear changes from using your slow-twitch muscle fibers to fast-twitch fibers. You'll fatigue faster, and burn out well before you hit the time needed for good cardiovascular stimulus. Gearing isn't used to make the ride harder or easier, it's used to maintain your cadence in a specific power band (e.g., 85rpm @ 200W) like the transmission in a car.

Cycling is special IMHO. It can be strenuous exercise like running, or a casual cruise that's even easier than walking. The speed is highly adjustable and easy to get in the sweet spot for that moment. It's not too slow to get bored, and not too fast to miss out on your environment.

Bikes are also a wonderful expression of physics, and the effect of centrifugal force is a key reason why cycling is special. The property of increasing stability with speed is amazing. Leaning not steering is also wonderful. The flow state you can achieve on a bicycle is unreal. Mind, body, and your physical environment in unison.

There's a mechanical beauty as well, that's easy to understand, but with plenty of depth to dig into and enjoy. Wheels and gear ratios are some of humanity's greatest achievements, and you get to pair that with interesting geometry and materials that have a direct impact on your experience. The difference between riding a junker that's not right for your body and a nice/fitted bike, is like the difference between wearing a burlap sack and a tailored suit.

Physical exercise is good, but bikes are much more than just a means to stay fit and produce endorphins. I wish everyone would bike more. Truly one of life's great joys.

And efficiency! A human on a bicycle is more efficient than any other vehicle or animal. If we ran on gasoline, a cyclist would get the equivalent of roughly 1,000 miles per gallon. A well maintained bike drivetrain can reach 98% efficiency. Compare that to an ICE car which loses up to 70% of its energy to heat and friction.

by thewebguyd

5/23/2026 at 2:21:06 AM

Where did you get this? Humans, like all mammals, are not very efficient at converting chemical energy into mechanical work, definitely less efficient than ICE at 30% COP (aerobic process gives about 20-25% COP and anaerobic is horrible 5-10).

by pandaman

5/23/2026 at 4:18:07 PM

Humans are not metabolically efficient, yes, but on a bicycle the total transport efficiency is more efficient than anything else, and 30% for an ICE car is in ideal, optimal conditions. Real world stop and go driving is likely closer to 15%.

A human on a bicycle is efficient because of mass and that the bicycle itself is a very efficient machine. A cyclist will burn around 30cal/mile of riding. If a gallon of gas has about 31.5k kcal of energy, then that's about 1,000MPGe for a human on a bike. A 200lb person + 20lb bike requires very little energy to overcome rolling resistance compared to a 2000+ lb ICE vehicle that spends the majority of its energy just to move its own mass.

by thewebguyd

5/23/2026 at 4:38:33 PM

I don't know what "total transport efficiency" is or how is it measured, I just noticed you mentioned 70% of energy wasted by ICE as if humans waste less than that. As for more efficient than anything else in terms of MPG, you might want to check the current MPG record, it's in range of 15K MPG on some hydrogen powered car if memory serves.

Not scientific but I enjoy actually going somewhere. Jogging you can get to places in your neighborhood, but cycling I can get to places in my region.

That’s why I get on the bike, you’re moving through areas slowly enough to enjoy them but quickly enough to really take in a lot.

Addition to what others have said, it's also therapeutic. Like exploring new places, the feeling/sounds. It's not detached from the environment, like it is in the car, nor it is too loud like it is on the motorbikes. It's not too fast, nor to slow to enjoy the surroundings. And, the sound of the hubs, wheels can feel peaceful even.

In my case, my city is disgustingly depressing. But after I started riding, I realized the city had so much greenery around it. And no car or motorbike could access it. Riding down the village roads, between the trees, that you can not access by a motor vehicle, or walking, is an amazing experience. And, it does not damage the environment, nor ruins the peace with loud noise.

by t_mahmood

5/23/2026 at 7:38:38 AM

FWIW I have found cyclists to often ruin the experience if you are walking or running through said greenery.

They go fast down the lanes, are often shouting and roaring at walkers to "stand back" or "get out of the way" (...at the polite end of the spectrum...) as they approach from behind at 20-30mph etc (assuming they warn you at all and don't whizz by with just a few cm/inches gap), if it is a soil track they will often leave tramlines in the mud that gets baked in and so on. And let's not even start on what they are like in urban environments (tl;Dr - habitually ignore all the rules including red lights etc)

IME cyclists are entitled, arrogant, and selfish. Maybe you are nice and respectful, but in my lived experience in and around London as a pedestrian and runner 90% of cyclists are total arseholes.

And it's not just me - arrogant selfish cyclists who don't give a crap about anyone else are causing issues across London, e.g. two random articles of many: https://www.bbc.co.uk/news/articles/c150n02d10po https://www.bbc.co.uk/news/articles/c62lp6xzzd0o

What is the source for the 90%?

But of course, there are always 2 sides of the coin. So, shitty people exists, but does not represent the whole group.

How many pedestrian, cyclists or runners are killed by drivers? Where did the term rolling coal comes from? How many people gets killed by drunk drivers?

Just some examples.

I've many time faced drivers who thinks they own the road. Coming from the wrong side trying to push me. And, I would be an asshole to them, because, I stood my ground.

You should report that to animal control. In most cities, dogs are not allowed to be running loose off leash and "at large." If they are bothering people, it's clearly an infraction.
