I hope that sort of price drops continues to similar devices like the MXB Motocross-boards (motocrossboard.com) I have been looking at them for a while as alternative to driving, as work home and classes are not exactly close together for walking and biking.
not really true - if you walk 10-12 hours a day, i'm pretty sure you could eat anything you were capable of and not gain weight (assuming that you start in reasonably good shape - if you're already overweight then just walking would put you out of the fat-burning "zone")
According to Mayo Clinic, walking at 3mph burns between 314-469 kcals/hr [1], depending on weight. That's 3140-5628 kcals for 10-12 hours of walking, depending on weight.
Now consider the amount of calories available [2].
I could have the IHOP meal for breakfast, walk for 12 hours (side note: who the heck has time to walk for 12 hours?), not eating anything all day, then eat the Dickie's meal for dinner, and still be well over the kcals burned.
jp555 is right, you can't out-exercise a bad diet - what you eat matters.
The fat burning zone (I prefer the term "fat burning bias" because it's not a switch but a gradient) would only begin to dominate as you use up all the energy in the food you eat. Any food you eat (not just carbs!!!) will cause insulin to be released, which "smothers" the fat release signaling (just like you wouldnt dip into savings when you have cash on hand). Only when available food energy diminishes, and therefore insulin diminishes does the catecholamine (epinephrine, etc) signal dominate, driving body-fat release for use as metabolic fuel.
"Why do Segways provoke this reaction? The reason you look like a dork riding a Segway is that you look smug. You don't seem to be working hard enough."
The funny thing is all these "hoverboards" are the same exact device from China. You can get them off alibaba for $200 or spend $1,500 for some American branded version that is the same exact thing.
Tons of reviews on Youtube, a lot of people take them apart and find that modelX is the same as modelY and so on. If they look close to the one she has, it is the most rebranded model. Check out Amazon and search for 2 wheel hoverboard, peoples reviews tell you too.
Yeah, I was reading a little about it and it's fascinating. It's a case of the full product development capabilities moving into the actual factory, so no outside company needs to design or own the product. The actual factory stamps it out and the outside company just brands it and sells it retail. And when combined with nonexistent intellectual property protections, in this case, no one even seems to be sure which company or factory originated the design. And no one cares.
The downside is there is no way for the consumer to rely on a trusted brand with good quality. It's a total crapshoot.
From what I understand there are differences in the quality of the components, but it's impossible to tell which brand has which set without doing a teardown on it.
Reminds me that a design company was pitching the conversion of the London underground into a network of conveyor belts.
5 lanes, 3 speeds, so that the ones closest to the edges were just about walking speed, while the innermost was somewhere close to a jog (or perhaps even a run).
To be clear, with most of the celebrity adopters, they're often given the device and sometimes paid to use it.
Here in Toronto, I've seen marketing teams of people handing out this device and rolling around Yonge-Dundas square (sometimes cast as times square in feature films) in a guerilla marketing push.
It doesn't mean they're not cool and fun, but the breathless articles about how cool, hip, and trendy people are "suddenly using the device" are often coordinated.
I have one of things. Bought off Alibaba for about ~$300 shipped.
It is fun, but you have to be very careful about stepping on. It is one of those things where the more you panic the more something goes wrong as you overcompensate. I fell when I tried to step onto one on concrete and it was way faster than I was use to so I overcompensated for the pressure my foot was causing and landed hard around my tail bone. And by that point I was pretty experienced getting on (just not on concrete).
Snowboarders seem to have a pretty easy time with it. But again, getting on without help is probably the most difficult step.
I'm not sure the ban on public use is a bad thing. I imagine they'd become a nuisance if a lot of people were using them. There's quite a difference between someone walking into you and someone crashing into you at 14mph on a 10kg set of wheels. Bicycles are used on bike lanes and on the road for a reason.
>I imagine they'd become a nuisance if a lot of people were using them.
My image of them was already soured by just one guy in an airport a couple weeks ago doing a lazy slalom in front of me while I was trying to get around and to my flight.
Well, as long as people are willing to risk life and limb in the pursuit of fun and thrills, I can't really talk down on them.
Also I can't wait to get some more traction in my side project so I can get my "recreational personal flight device" into a prototype and testing stage. Think of it as akin to JetMan, version 2.0, and not needing a helicopter.
"All of them should be allowed on the pavement, because people aren't stupid, they will get out of the way if they see one coming."
Speaking as someone who sometimes puts his back out and spends a few days hobbling slowly about, I shouldn't have to quickly get out of someone's way if I see them coming and they shouldn't be allowed on pavements.
I doubt having your back out is ideal condition for riding a device where you may have to hop a couple of steps to catch your step if you mess up anything.
You shouldn't ever have to move out of someones way if they are not walking. I live in NYC so perhaps my perception is skewed but pedestrians should always have the right of way.
Don't move for runners, bikes (shouldn't on sidewalks unless it's a kid) or these things. It's up to the user to manage themselves and prevent themselves from hitting and potentially hurting others.
I see these around here and there, more and more, and don't mind them for now but if we start to get a problem with users hitting people then I'll support a sidewalk ban on them.
I wish this were the law everywhere. It varies by jurisdiction. "Each city in California has its own rules about riding a bicycle on the sidewalk. Some cities allow sidewalk riding, some don’t. Check with your city’s municipal code." (http://la-bike.org/resources/california-bicycle-laws)
Assuming you mean where it is an offence to ride on the sidewalk, I'll always choose angry peds or a penalty over getting killed by a coffee-drinking, cell-phone talking urbanite in their range rover. Or non observant lorry driver. Or bus running a red light. Etc.
Cycle a bit in a city and you'll change your view.
I don't own a car and ride almost everywhere. In all the cities I've lived, my experience has been the exact opposite. Since the majority of accidents involve intersections, riding on the sidewalk doesn't do much other than put you in a less visible position, where drivers don't expect you to be and won't be looking for you.
Cycling on sidewalks feels safer, but it's actually more dangerous. [1] The problem is that cars don't expect something moving quickly on the sidewalk, and so hit cyclists at driveways and intersections.
There are places that are shared pedestrian/bike paths. The east side of the GG Bridge when the west side is closed for instance. In those cases I think pedestrians should at least be aware of cyclists, instead of walking 4 abreast and blocking the entire way.
Don't give me that crap. I can't count the number of times I've been nearly run over by cars who refuse to give me my right of way and try every possible trajectory just so they won't be in any way impacted by a person on a bicycle. The only good part about riding on the road is the satisfaction from hearing the honks of asshole cars. I'm taking my right of way and we're paying with our lives if we have to. Fuck cars.
And before you start saying I'll be endangering pedestrians with the same outlook - no. Pedestrians have the ultimate right of way. If there are 8 walking abreast and don't make way when I ring, then so be it, I'll go at 2kph until it's safe to pass them. I'm not in a hurry.
The people who hit pedestrians are assholes. Pedestrians have the ultimate right of way. If they refuse to move, then you have to go slow. Just increase fines for hitting people and the problem will go away. Responsible people shouldn't be impacted by assholes who have to shave that last second from their hipster commute.
A bit off topic, but have you tried yoga to help your back problem? I've thrown my back out a couple of times and am in the process of integrating yoga into my daily routine, want to know how well it works (if it works).
Not OP, but while I've had a lot of success, the evidence doesn't support blanket application of 'Yoga' to back pain. The real problem is that back pain typically goes away regardless of treatment modality, which leads to a lot of people who grab the last thing they tried as "the real thing that fixed my back".
yeah, I realize it's not going to cure back pain, I just want it to improve my musculature. I think I keep pulling things because I'm at a computer all day and don't do a lot of movements/stretches.
Completely agree. I don't see any hovering going on. Of course, I'm still on the losing side of the battle against the "sharing economy" phrasing, so I might as well accept this one too.
How fast do these go compared to a bicycle? I saw a few of them on the street and they didn't seem to be moving faster than a brisk walker.
My impression was that bikes are generally banned because they move fast enough to cause serious injury yet are silent enough that pedestrians don't hear them coming.
I've seen a few of these in London they aren't really faster than a fast walking speed which makes people who use them look very silly.
They are quite often laughably used in shopping centers or and super markets mostly because allot of the pavements in London are horribly uneven which probably doesn't provide a very good surface for those.
I've seen 2 guys on those things at Westfield last weekend arguing with a bunch of confused staff that didn't knew how to treat them.
I don't really get this device it doesn't help you to commute any faster, it doesn't increase your pedestrian commute range if you aren't fit to walk you won't be able to use one of those (they got quite a stringy weight limit, and require quite a bit of effort to balance yourself on) anyhow.
It's a bit funny to see fit and young hipsters pretty much using a 500$ mobility scooter...
I'm guessing, the larger single wheel gives you a smoother ride? They're easier to pick up and carry like a briefcase, too. But I imagine, harder to ride.
I was working on iBot cost reduction stuff back in 1999 when that patent was filed. I was under the impression the company (our customer) had a lot of balancing machines running around at the time and figured the patent must have been a few years old at that point. Guess not.
It's not practical to design everything in the world with the very slowest people in mind. The efficiency losses would be huge. Imagine if every pedestrian crossing light went for five minutes. Vehicular traffic would grind to a standstill.
Actually, there was a study in the UK a couple of years ago that didn't get acted on, but which demonstrated that pedestrian crossing lights in British streets allowed so little time for crossing that able-bodied teenagers had to hurry -- middle-aged, elderly, unfit, or handicapped people really need about triple the time.
The solution is probably a combination of the sensor-controlled systems showing up in newer crossings in the UK (IR sensors block traffic by setting a red light until the crossing is clear) and cutting down on automobile use in densely populated areas like urban cores. Ahem. (Hint: why should your one ton rolling steel status symbol trump anybody else's right to use the highway?)
The study was very flawed. The 85 percentile walking speed for pedestrians (1.2 m/s) is for when people start the crossing at the end of green man. So some 15 percent of the people are slower. However if youo take into account most people start crossing before the end of the green man, then the time is ample. "the sensor-controlled systems" - are hopelessly inefficient and actually confusing for pedestrians.
A countdown which displays the time until the red-man is best for a balance of all users.
The green man is intended as a sign that it's safe to _begin_ crossing the road - at least in the UK. You'll notice that the man changes away from Green long before the light sequence. That's intended.
How are you supposed to know how long it has been since the green man appeared? Presumably if it turned green while you were waiting, you would have started walking immediately. Do you have to wait until the next green man if you arrived at the intersection while the light was green?
"The very slowest people" are actually the majority: the elderly, the very young, the temporarily or permanently disabled- if you put all of those people together they're many more than the young, strong and fast.
What's more important, each and everyone of us, will inevitably, at some point in their lives be very young, elderly or disabled. In fact most of us will probably be each of those things during our lifetime.
So it's not so much a matter of efficiency as accepting the fact that human beings are not born with wheels, but with feet and that they should always get priority, despite any misunderstandings about what the purpose of "efficiency" is in the first place.
>"The very slowest people" are actually the majority: the elderly, the very young, the temporarily or permanently disabled
That is quite simply not true. http://www.censusscope.org/us/chart_age.html As you can clearly see, most of the population falls in the age range that has no trouble walking at a reasonable speed. I don't have exact figures on how much of the population is disabled or seriously injured at any given time, but experience says it's not enough to make up for the fact that the very young and the very old are very very far from constituting a majority.
I'll qualify my comment: "the very slowest people" are the majority _in the developed world_ where the median age is 35+ (Wikipedia). It's also where people are the most likely to use hoverboards.
In any case, you can dispute the numbers and it makes no difference. People are not born with wheels. We need space to walk about. By convention and by law, the pavement is not for vehicles.
Despite that, I'm prepared to share the pavement with people on wheels but it has to be absolutely clear that it's not my responsibility to avoid them. It's theirs. They are the ones choosing to put me at risk, they should take full responsibility for it. And watch where the bloody heck they go.
What's fascinating to me is that now, 14 years after the Segway failed to take over the world and became indelibly associated with upper-middle-class nerds, similar technology is now 90% less expensive, has found a more socially-acceptable form factor, and is actually becoming associated with celebrity tastemakers.
It would be quite the irony if the breathless hype about the Segway circa 2000 ended up being realized a decade and a half later, without the Segway.
I've thought about that a lot, and I think new tech adoption relies more on the social framework that's in place around it than we think. Simply put: if it makes you look/seem like an asshole then it's not gonna happen unless it's too good to ignore.
Smart watches and bluetooth headsets are great examples: they work fine but they make you look like a tool because of the social frameworks we have in place (it's rude to check your watch while in a conversation, it makes people feel weird when they think you are talking to them but you are just on your bluetooth.) Smartphones didn't deal with this friction because there's a long history of social rules around reading in public, and smartphones are essentially the same thing. We know when it's rude and when it's not, we know how to handle somebody reading next to us in the train, etc. In short, using a smartphone didn't make you look like a tool, it was just the next logical step from reading a magazine.
It's way more conspicuous than those sneakers with the wheels on the bottom and those sneakers really took off in some parts of the US. Did they cause a lot of problems for people?
I don't know, but these hoverboards probably won't be as popular as those sneakers.
> American rapper Wiz Khalifa claimed on Twitter that he was handcuffed by customs and border patrol officers at LAX airport because he refused to disembark from his transporter.
I don't know whether the officers were justified in ordering him to get off the transporter (I tend to side with civilians), but this is kind of dumb. What was he expecting to happen? I can understand getting arrested intentionally to make a political point, but is this really the political stance he wants to take?
Either he was too dumb to know he was going to get arrested, or he's making a pretty irrelevant political point.
Well, it's not that different from writing blog posts in the hopes that they show up here. Humans are social and connections even asymetric ones are valueable.
My objection is that Wiz Khalifa's bid for attention worked, despite the fact that he had nothing of value to say. I'd hope that if someone wrote something of no value it wouldn't make it onto the front page of HN.
Is there any open source for the control system? It's not rocket science but from what I understand getting a control system running with dynamic feedback is not trivial either? Anyone experience with the theory? Any books/papers you can suggest?
Don't want to sound like a killjoy but those seem absolutely pointless. If you made one so small it would fit in a sole of a shoe I'd reconsider but in their current form they're just as inconvenient when not in use as a bike and infinitely less useful when riding.

Skateboards burn much less energy than walking too. I don't see anyone calling them obesity boards. Or calling motorized bikes obesity bikes, etc.
Per distance traveled, sure.
But probably not per minute, in typical use.
In a place like London that's very walkable, but very large, it makes sense.

The price is prohibitive, but the market now has something like 7 or 8 brands competing, so I expect the price will come down in the next year or so.
Honestly I'm not sure what order they came in, but the Magneto electric board has several look a likes that are in the ~$300 range:
