Electric bikes might just be the healthiest thing to ever happen to teenagers

wbly•6mo ago
E-bikes might be the first tech in decades that actually gets teens off screens and into the real world without feeling like a chore. That’s a win.
y-curious•6mo ago
I think this tune will change once more reliable data comes out about injury statistics, especially serious injuries. Where I live (suburbs in the Bay Area), I see gangs of teens doing extremely reckless things on busy roadways. I can't imagine giving children motorcycles before they know the rules of the road is going to go unnoticed
harambae•6mo ago
I know parents who start their children racing motocross dirtbikes around age 6. (Meanwhile, my brother is making sure his dinner table corners are padded for his 7 year old to not run into... different parenting styles, I guess)
ryandrake•6mo ago
Yea, I don't think we ought to let (real OR imagined) fears of injury suffocate new inventions that might help get kids out of the house and active. Growing up in the 80s, we roamed freely and got injured all the time, sometimes seriously (broken bones, torn ligaments, probably concussions--I don't remember because my brain doesn't work anymore), and most of us turned out fine!
y-curious•6mo ago
This anecdote is survivorship bias quite literally. There are many people that are dead from lack of regulation during the 80s that cannot comment.

I agree that we shouldn't let fear rule us, but I think the risk of fatal and disfiguring accidents is high on roadways in the US. It's kind of like letting your cat be an outdoor cat, but instead of a sad nextdoor post we are going to be seeing teen funerals

y-curious•6mo ago
Racing bikes on a closed course is many magnitudes safer than riding an electric motorcycle on a roadway in the US. I think people don't consider how distracted drivers of multi-ton vehicles are
VeejayRampay•6mo ago
so the healthiest thing to ever happen to teenagers is transportation devices that allow them to pretend they're exercising... we've really given up
amelius•6mo ago
If the lack of exercise becomes problematic we can always give them Ozempic, I suppose.
SoftTalker•6mo ago
Yep, train them early to think that there's a pill for everything. Big Pharma approved this message.
JKCalhoun•6mo ago
No, the kids running around in golf carts in my neighborhood have really given up.
ploynog•6mo ago
No, you are just oversimplifying the issue. Of course, if you were regularly riding before and very fit and change to an e-bike out of laziness, the net effect might be negative, tho even that part is not conclusively proven.

But if you found biking way too exhausting, maybe living in a hilly area, riding an e-bike is ten times better than doing nothing. Would it be even better to ride a non-e-bike? Maybe. Would it happen? Probably not.

VeejayRampay•6mo ago
your reply is oversimplistic as well

we're now in a world where the youth of developed countries are way more overweight than they were before, because of a radical shift in diet and exercise

upon reading that using electric bikes (that are basically mopeds disguised as bikes, i.e. which do not induce "real" physical activity due to assistance from the motor) are the healthiest thing to ever happen to teenagers, I have the feeling that the title is being a bit over the top

I'm not even talking about being fit or anything, just that actual bike riding (normal bikes) or just walking maybe would be actual good news. I understand that people in hilly areas benefit from ebikes, but is this the majority of the people mentioned here? or is it just that we're all like "well, I guess it's better than staying inside all the time eating doritos"? That's why I'm saying that this is a sign that we've given up, we're counting this as some sort of win, which I don't think it is

theshackleford•6mo ago

Maybe you should read more than the title than? Like say...the article? Just a suggestion.

VeejayRampay•6mo ago
that line of "someone says something I don't agree with so I will insinuate they didn't read the article" is tired, seriously

an excerpt from the article you pretend I didn't read (which I did)

  But let’s be honest: even throttle-only riding is more active than sitting on a couch
the article is literally saying that

it's also saying things about mental well-being, the sense of community, which I can get behind of course, but there's some sense of course to the bottom in our expectations

theshackleford•6mo ago
> that line of "someone says something I don't agree with so I will insinuate they didn't read the article" is tired, seriously

Except... you clearly didn’t read it, or you read it and didn’t understand it. I actually gave you the benefit of the doubt by assuming it was the former.

> the article is literally saying that

The article is literally saying a lot more than just that.

You cherry picked one point out of a multi-faceted discussion about health benefits, ignored the rest, and then acted like that narrow takeaway was the entire message. Pro tip: “health” doesn’t just mean physical exertion.

So again, either you didn’t read the article, or you didn’t get it.

> it's also saying things about mental well-being, the sense of community, which I can get behind of course

Cool. But no one’s asking whether you can “get behind it” and nor does anyone care. The point is those are part of what makes it beneficial.

JSR_FDED•6mo ago
It’s all relative I guess. In the Netherlands which has a strong cycling culture, the e-bikes are seen by many as a negative - reducing the amount of exercise kids would otherwise get. It also emphasizes a rich/poor divide (which the Dutch are extra allergic to) where well-off kids have e-bikes and the others regular bikes.
bell-cot•6mo ago
The Netherlands is a rather dense, flat country. Generally not too hot, either. All of which reduce the downsides of pedal-pumping on a regular bike.
Freak_NL•6mo ago
From what I can tell looking at teenagers in the Netherlands: healthy kids have normal bicycles; kids who actually have to cycle 20km from some village to get to school often get e-bikes (somewhat sensible); those with upper middle class parents living in the suburbs get regular e-bikes too (pointless); lower socio-economic classes get their kid a Chinese fatbike.

Mopeds are becoming increasingly rare.

arp242•6mo ago
> Mopeds are becoming increasingly rare.

How will we demonstrate the Doppler effect to kids now?!

I haven't lived in NL for about ten years, but I still have PTST from these 100dB mopeds at 4am. Whatever else can be said about e-bikes: mopeds will not be missed.

graemep•6mo ago
Ebikes are mopeds with less regulation so there is no real reason to get a moped.
windexh8er•6mo ago
In the US this allows kids who are not of age to drive to be able to use their bike like someone would use a moped. But since these kids don't have licenses or any oversight they're flying at 25+ mpg down sidewalks and other areas they shouldn't be.

Saw a hilarious exchange of some cops vs teens on ebikes in a relatively affluent restaurant area a few months ago. The teens were taunting the cops as they had their normal vehicle and obviously couldn't go where the teens were. The teens just ignored the cops as they feverishly got nowhere.

ulf-77723•6mo ago
I moved to the black forest, germany. Rather hilly - but you see as many e-bikes as bio-bikes when being in the woods. Teens use their bikes to drive to school and e-bikes are definitely slowly taking over. When kids live 20-30km away from school I can relate, but not for a short commute. On the other side, they want to use their e-bike as a sport utility in their free time, so they don’t have 2 separate bikes.
rychco•6mo ago
This is cute, but the real reason our teens are inactive & unsocial is because of awful zoning laws + exurban sprawl. It’s not realistically possible to meet your friends anywhere, their homes are too far away & there aren’t any third-spaces to spend time at.
JKCalhoun•6mo ago
That never stopped this 70's kid who grew up riding a bike in the suburbs. (There was a brief moped craze though. I couldn't afford one.)
SoftTalker•6mo ago
Yeah my hometown in the 70s was entirely suburban in style. We rode bikes all over the place.
hombre_fatal•6mo ago
In Houston, my girlfriend and I share a car since I work from home and she doesn't which is sufficient for 95% of our needs.

Yesterday I went to a meetup.com board game night by myself while she was at work and the only option was to take a $17 Uber there even though I live as central as you can get (central means very little in a place like Houston).

It's especially ridiculous after living in Mexico City which has world class mass transit and the liberation to go where you want with nothing but 5 pesos. Houston's mayor calls cyclists "activists" and routinely rips out or rejects bus and bike lanes. Huge lifestyle downgrade, but I love her and this is where she got a job.

poemxo•6mo ago
Won't anyone think of those exurbanite children who live in such uncramped areas?
MarkusWandel•6mo ago
Hmmm. Back in the day it was normal bikes that did all that. Young people can attain the necessary fitness easily.

I fear that once started on an e-bike, with all the benefits the article lists, the one thing that may never happen is changing to a conventional bike later. For example, some serious mountain biking Youtube channels I watch point out that electric mountain bikes are just as good at the cool stuff (berms, jumps etc) but simply take the drudgery out of getting to the top of the hill in the first place. If a less fit teenager on an e-MTB is seen as cooler than a more fit one on a conventional MTB... you know what will happen. The conventional crowd, though fitter, will be seen like the poor Android cousins to the "right coulour texting bubble" iPhone crowd.

Apfel•6mo ago
Sidepoint but they're also a complete gamechanger for the elderly and infirm.

My 70 year old, double-ankle replacement mother who I don't remember ever walking very comfortably bought an ebike a couple of years back.

The sheer joy on her face watching her whizz up a hill made me realise just how transformational these things can be.

rychco•6mo ago
Agreed. E-bikes have gotten my elderly relatives moving too. From essentially sedentary to active on a daily basis.

Teens + other able bodied people are inactive for reasons unrelated to ease of pedaling.

AaronAPU•6mo ago
It’s a weird experience having a grandma in front of me on the trail, and at my normal pace I’m not passing her.

That’s on my slow mountain bike, which I ride for comfort some days. But it’s still a weird experience.

_DeadFred_•6mo ago
I had a 67 year old lady shoot in front of my jeep last week on one of these while listening to iPods, obviously flying into a crosswalk full speed. She ended up flipping over her handle bars when she saw me, had road rash from head to ankles and her calf separated from her leg bone. She's never fully recovering from that spill. Lucky she wasn't on blood thinner or she might not have made it.

Our local bike trails allow them in certain sections and it's wild to see old people just zipping around. Our paths are single track but traffic both directions. Not sure what's going on, they have zero awareness, especially for someone that's made it to 70.

cadamsdotcom•6mo ago
Glad she’s alive - sad she got hurt. Now for the unserious part:

She learned at 70 a lesson she never got to learn as a teenager! She probably has some badass scars.

tim333•6mo ago
Yeah, I'm 60+ and the ebike is good fun and also pretty practical as transport in cities. When I was a teen I was fine with pedaling but have slowed a tad.
j_w•6mo ago
Four comments and only one seems to be related to the article.

The article is about "touching on independence, mental health, social behavior, and even environmental awareness" just as much as not sitting on your butt inside.

It talks about car culture and social challenges. It recommends class 1 e-bikes so you still have to pedal (no throttle). Yes e-bikes are "cheating" the exercise of cycling, but teens aren't getting e-bikes to go cycling they are getting them to travel without asking somebody to drive them.

Throttle e-bikes are a bit of a menace in my area, but that's whatever. If more people can get outside and enjoy life that's a huge win.

Aurornis•6mo ago
> It recommends class 1 e-bikes so you still have to pedal (no throttle).

Where I live, the trend is either to buy an electric motorcycle and ride it around as if it was a bike (on sidewalks, bike trails, crosswalks) or to buy a hackable e-bike and unlock the power limit and add a throttle.

The interest in real class 1 e-bikes seems minimal. The hacked e-bike and electric motorcycle people are making bike paths and trails much more dangerous for everyone.

Even the normal e-bike people have seemingly forgotten that there are rules. I had to jump out of the way of a middle aged woman who blew through a stop sign on her e-bike and turned right straight into us pedestrians. It’s common to see e-bike riders jumping between the sidewalk, road, and crosswalks as convenient and blowing through the four way stop by my house.

BlackFly•6mo ago
> This type of group riding brings back real-world socialization, which is especially crucial right now.

> many teens haven’t yet learned the road rules,

There are few nations in the world that respect cycling as a mode of transportation enough to legislate that cyclists are permitted to ride two abreast (I am only aware of the Netherlands). Instead, in most nations two cyclists out for a "convivial" trip together are forced to ride single file while two seat wide vehicles operated typically by a single driver in a vehicle wider than two bicycles riding abreast speed merrily by.

Let the teens ride side by side.

SoftTalker•6mo ago
Where I am you can ride side by side but are supposed to single up if you are impeding traffic behind you, so that they can pass more safely.
nicktelford•6mo ago
The UK Highway Code was revised a few years ago to explicitly allow and even recommend cycling two-abreast[1].

Teenagers in the rest of the developed world are also spending increasing amounts of time in front of screens despite not have the constraints imposed by American car culture. E-bikes might have removed one barrier, but that does solve the problem.

Kids where I live often, maybe usually, walk or take busses to school. If they pay monthly through the app they get unlimited bus travel in the county. Its not atypical in the UK, and its even easier (albeit more expensive) in big cities. We still have kids spending all their time doom scrolling.

I think it is a combination of over-protective parents and addictive stuff on their phones that is the real problem.

Ebikes are a definite menace here, and e-scooters are worse.

world2vec•6mo ago
Here in London, stolen Lime e-bikes sure seem popular with teenagers. That beep beep beep and click click click sound everywhere I go.
philipwhiuk•6mo ago
Free as in beer.
pfych•6mo ago
Whenever I go for a run in the afternoon there's always a big group of teens down fishing at the river with a bunch of lime bikes next too them. Glad it's made it easier for them to all meet up and hang out outdoors.

It's funny when they wrap up though and you watch all of them kickstart the bikes. Riding off down the trail as they beep and click. Haha.

JKCalhoun•6mo ago
While we have people weighing in on e-bikes in this thread: any recommendations on a decent one?

I want something that's not a cheap Chinese thing, but something of some measure of quality. I kinda hate the fat-tire thing and I'm not a real fan of hub motors (they add so much weight to the wheel that trying to ease a bike down off a curb results in slamming the wheel for me). I prefer mid-drive.

potato3732842•6mo ago
People who don't care about cycling or appealing to the morals of any demographic go out and buy fat tire throttle controlled e-bikes. What that tells me is that those are the best experience for someone who doesn't care about the details. Without personal experience in the details of a subject I would err toward not deviating too far from that. Nobody ever got fired for buying IBM.
mgraupner•6mo ago
Get one with a Bosch CX motor (at least Gen4 or newer with the smart system). They are market leaders here in Europe and they usually ride really well.

Canyon (German brand) sells bikes in the US with this system: https://www.canyon.com/en-us/electric-bikes/electric-touring...

gibagger•6mo ago
For the teenagers of which country, exactly?.

I live in the Netherlands, where the average teenager used to ride a regular Dutch city bike. Internal hub, no-frills bicycles.

Nowadays, however, fat e-bikes are all the rage among that age group. They are quickly becoming extremely popular, and are essentially electric scooters without plates or registration. Many of them require little or no effort to pedal, and can carry up to two riders in them. These are also designed to meet regulations, while also being able to easily be modified to circumvent them, such as removing speed restrictions, and removing the need to pedal itself.

This is also reflected in the shape of these things, which generally does not account for ergonomics. Their seat and handlebars are usually fixed in place. They appear to be designed without pedaling in mind, as exerting effort without proper ergonomics would quickly become uncomfortable and painful. You can actually see some such bikes in the linked article.

Time will tell whether this is truly healthy to them, but I have a hard time believing this to be the case. I think the fat bike demographic might start putting on weight.

arp242•6mo ago
> For the teenagers of which country, exactly?

United States, obviously. Article makes zero pretence being about anything other than that and it's stated right there in the opening paragraph: "among America’s youth".

FirmwareBurner•6mo ago
What was wrong with regular bikes that American youth had to wait for electric bikes to discover cycling?
j_w•6mo ago
American drivers tend to be extremely aggressive towards cyclists. Long distances mean you will get tired and/or sweat. Lot of 2 lane roads without shoulders or sidewalks makes cycling on them scary.

I do cycle (normal bike). These are some of the things that I told myself that kept me from getting into it when I was younger.

FirmwareBurner•6mo ago
> Long distances mean you will get tired and/or sweat.

Yes, that's what happens when you exercise, and judging by how fat Americans are, seems like they could use some.

>Lot of 2 lane roads without shoulders or sidewalks makes cycling on them scary.

How do ebikes fix this? It's still a bike, not a tank.

j_w•5mo ago
Bit of a necro.

On fat Americans: at the time and still I'm likely a 99.9%er cardio wise, and I still had the concern about being sweaty. I wasn't exactly trying to smell bad during lectures.

Ob ebikes not being tanks: Going 20 in a 25 is a lot less scary then going 8 up a hill where cars are BLASTING past you. Lower effort also means you can spend more brainpower on spacial awareness, when you are gassed you tend to notice less around you.

hyrix•6mo ago
Americans travel farther distances for many things, even within cities, and it’s not flat like the Netherlands
BlackFly•6mo ago
Yeah, those fatbikes are just the latest iteration of the old little scooters (bromfiets) with the small win of being more quiet. I feel like the size of them and the seating arrangement should enable them to legislate fat bikes as scooters while only catching a small number of modified pushbikes that the police would likely ignore when the cyclist isn't being a nuisance.

They'll definitely gain weight, it is quite easy to tell that they aren't exerting much effort during pedal assist.

gibagger•6mo ago
Yeah, very easy to spot if you pay a bit of attention to the lower back muscles. They are basically not being engaged.

Tire noise is enormous though. I think their tires are made / selected with this in mind, as young males often do like to get attention. Most e-scooters are way quieter than these ugly things.

avar•6mo ago
Before the "fat bike" phenomena the same demographic used to ride around in "snorfiets" scooters which were theoretically limited to 25 km/h, but pretty much everyone modified for speeds of up to 50 km/h.

But somehow the Dutch have this collective amnesia on the topic, and today nobody remembers how the "snorfiets" problem of 10-15 years ago has pretty much disappeared, to be replaced by a quieter and safer mode of transport (even ilegally modified E-Bikes usually fall far short of modified "snorfiets" speeds).

    > [...]appear to be designed without pedaling in mind,
    > as exerting effort without proper ergonomics would
    > quickly become uncomfortable and painful.
This is a trend in E-Bike design in general, which makes sense. When they first came out manufacturers were just adding a motor and battery to existing designs.

The "fat bike" design is something that wouldn't work well unassisted, because it trades a severe increase in rolling resistance for better ride comfort.

But as a clean sheet design it makes more sense than the alternative. Why incorporate a complex suspension design (which, to be fair, some of them also have), when you can just have the tire absorb the bumps in the road? The marginal cost in electricity is trivial.

Aurornis•6mo ago
> (even ilegally modified E-Bikes usually fall far short of modified "snorfiets" speeds).

Class 1 e-bikes are limited to 32 km/h here, but simple mods push them well above 50 km/h.

Many of these bikes are designed to be hacked, with unlocked power output significantly higher than the locked output. It’s a selling point and a key part of reviews.

gibagger•6mo ago
> This is a trend in E-Bike design in general, which makes sense. When they first came out manufacturers were just adding a motor and battery to existing designs.

It's only a trend because people are not using them like bikes. The people who still want to pedal but need help because of illness, old age or too-long-distances for normal cycling often purchase actual bicycles which use normal bike parts.

> The "fat bike" design is something that wouldn't work well unassisted, because it trades a severe increase in rolling resistance for better ride comfort.

That is an understatement. People would quickly develop knee and/or lower back pain if they had to put any effort for any meaningful distance.

avar•6mo ago

    > It's only a trend because people are not using them like bikes.
Who's using E-Bikes "like bikes"?

The grandmother maintaining an easy 20 km/h against strong headwinds on her Sunday cruise? The petite mother bringing her kids to school at a comfortable 20 km/h in a 50 kg cargo bike, something she'd probably struggle to do at 5 km/h unassisted by an electric motor, if at all?

The fact is that E-Bikes have have opened up all sorts of use cases that wouldn't be practical without motor assistance.

I don't think "Fat bikes" are a particular outlier here. The basic design (or something similar) has been around since the 60's[1] as lowrider bikes. Fat Bikes provide basically the same riding geometry, only with an extra wide tire.

    > actual bicycles which use normal bike parts.
I can assure you they use "normal bike parts", e.g. Shimano shifters, brake discs, or similar. Despite the rhetoric around them, they're not actually in the performance envelope (even when speed unlocked) of requiring actual motorcycle parts.

Yes, the frame and seat are custom/unusual for a bicycle, but the same is true (at least for the frame) for a lot of modern bicycle designs, e.g. VanMoof and Cowboy bicycles (both of which you'd presumably consider "like bikes").

sebazzz•6mo ago
> Before the "fat bike" phenomena the same demographic used to ride around in "snorfiets" scooters which were theoretically limited to 25 km/h, but pretty much everyone modified for speeds of up to 50 km/h.

The difference is, of course, that a snorfiets/bromfiets requires a driving license (AB) and a fatbike does not, nor does it have any age restriction. A classic case of the legislator not keeping up.

avar•6mo ago

    > A classic case of the legislator not keeping up.
This isn't the legislator not keeping up. Not requiring insurance or licenses for E-Bikes where the assistance is limited to 25 km/h has been law across the EU since 2002. There was a deliberate decision to treat them like bicycles, not motorcycles.
gerad•6mo ago
Here in Marin it’s not allowed to use an e-bike or scooter with a throttle if you’re under 16. Nicely catches all the edge cases.
Aurornis•6mo ago
> These are also designed to meet regulations, while also being able to easily be modified to circumvent them, such as removing speed restrictions, and removing the need to pedal itself.

This is the trend near me: Kids buy hackable e-bike, immediately unlock it, and then ride their new electric scooter (motorcycle) around pretending it’s an e-bike.

There’s a separated mixed use bike path parallel to a road on my commute. It’s typical to see e-bike kids driving up it faster than the road traffic on the road, while pedestrians and families jump to the side.

This is exactly the same as the mopeds that were popular when I was a young teen (over 40 years ago).
whywhywhywhy•6mo ago
You need a license to drive a moped, you can hear them coming and people never drove them up the sidewalk, it's completely different.
SoftTalker•6mo ago
We didn't need a license, by virtue of the displacement of the stock engine being small (IIRC the limit was 125cc? Or maybe even less). They also had to have pedals, so small motorcycles or vespa-style scooters did require a license. Or at least a registration.

The mopeds would barely go 30mph as sold. That was hackable though if you were so inclined and had a set of wrenches.

SoftTalker•6mo ago
Too late to edit but I was way off on the engine size.... 50cc displacement or less.
harambae•6mo ago
Yeah 49cc mopeds that aren't registered appear to still be a thing where I am (Boston). And I think it's 49cc 2-stroke so equivalent to like a 90cc 4-stroke (whether that ends up violating a different emissions rules, I don't know).

Still, parking is such a racket in Seaport, including unnecessarily strict ticketing on motorcycles, that I don't blame the delivery guys for using the mopeds. I'm not sure what their realistic alternative would be.

Mopeds are still around. It’s completely different than a bike that can appear to be a normal bicycle on a bicycle path.

I also live here, and while i agree Dutch teens should be riding regular bikes, we here are in the extremest of minorities around the world in terms of what teens would be doing without e bikes

> They appear to be designed without pedaling in mind, as exerting effort without proper ergonomics would quickly become uncomfortable and painful. You can actually see some such bikes in the linked article.

Came here to write exactly that. Those who design those bikes clearly don't know a thing about bicycle design. Want to use them for pedaling? Say hi to knee problems and inefficient pedaling!

amelius•6mo ago
I have seen these bicycles in DE also, they look more like motor scooters.

Can't they be regulated based on weight or otherwise the width of the tires?

muststopmyths•6mo ago
That's just, like, your opinion man. (i.e., it's not some scientific study)

Although I do agree that if it encourages the yutes to get outside and socialize that seems like a win.

IneffablePigeon•6mo ago
There’s a lot of research that for the average person, getting an e-bike will result in more exercise than a normal bike. Not because you work harder on one but because you’ll use it more. My knee jerk reaction was the same as yours but I’ve changed my mind on it.
muststopmyths•6mo ago
I think you are misreading my reaction. All I'm saying is that TFA's not a study but some guy's opinion.

But, as I said if it encourages healthy behavior, that's great.

Unpaid Lime bike use might be the healthiest thing to happen to teenagers in the UK.

As a paid Lime bike user, I don't mind this.

Unpaid, they are terrible heavy bikes - but that is clearly better than no-bike.

Lime already somewhat violates social contracts by having their bikes everywhere.

acheong08•6mo ago
They've been removing those bikes around Cardiff since a year back. Can't find them anywhere anymore

I'm pro e-bike for reasons other people have mentioned:

-It's a big win for the elderly and out of shape who otherwise would not be getting that exercise and fresh air at all. I have a friend who's Aunt has a heart problem and apperently otherwise wouldn't be unable to bike without an e-bike.

-It brings many new people into the orbit of biking that otherwise wouldn't. The more bikers the more demand for good bike infrastructure, and the fewer cars on the road, and the more attractive biking becomes as a means of transport in a virtuous cycle. This could be huge.

Though I do worry about a few things:

-I think with its battery an e-bike is significantly more of an issue when people do stupid things like throw bikes in rivers/lakes/ponds. Even if this weren't common in places it still needs a good end of life for recycling.

-I do think maybe some people will be so used to an e-bike smoothing out the ride that they will never go to a full bike, but this may be a relatively low number (e.g. many people choose to bike over driving because they want to exercise)

-Many people on e-bikes in my area are a bit of a menace. Because it takes no effort to use, people fly around at max speed (well above the limit posted on our bike paths) and e-bikes are heavy; if someone gets hit it might seriously injure them. I think it may end up giving them a bad reputation if they aren't managed well.

yeah on the one hand there are clearly good things about them.

But just solely from my own actual personal lived experience, they are making my rides less enjoyable on a daily basis.

I’m hoping much of it will be ironed out over time as etiquette catches up. But I dunno, once the masses flood any given environment it tends to become permanently worse.

daemonologist•6mo ago
Ebikes are great, but here in the suburban US I only see teenagers on electric scooters (standing/kick scooters), presumably because they're slightly cheaper, or non-electric bikes. The ebikes I do see are used exclusively by adults. There might be some coolness gradient at play in addition to the cost, not sure.
harambae•6mo ago
The teenagers in San Jose ride Surron-style ebikes all over the place and it's pretty suburban where I am.

(Might have to do with the weather and/or affluence? In a lot of places you can't bike year-round and an ebike is a bigger investment for only 6 months.)

amelius•6mo ago
Just a note that:

    exercise : e-bikes == real thinking : AI use
tartoran•6mo ago
Nobody seems to be mentioning electric unicycles which are great for training ballance and the core. Once one gets over the steepish learning phase (a couple of hours or training) they are extremely versatile on all kids of terrain.
