  1. @esaj, I have been riding motorbikes for years and a suggestion to make :-) For me, the fun-factor of riding increased significantly when I started using an open (cross-)helmet^1 and glasses^2, instead of a visor. It's hard to say why, but getting the air in the face, the nose in wind, just feels so much better. I can't remember the lowest temperature which I found tolerable without visor though. ^1 https://www.louis.eu/artikel/madhead-x2b-helmet/215563?list=100450365 ^2 https://www.louis.eu/artikel/spare-glasses-shark-raw-vancore/20015551?list=100450745
  2. The sentence is factually wrong. What carries (most of) the weight is completely irrelevant for the position of center of gravity. Right, if the seat of a bike is positioned correctly (i.e. not "too low", which it often is), it raises the hip by somewhat above 10cm (compared to standing up-right), but 10cm is also the lift with an e-wheel due to the pedals (in low-position). That wouldn't give us much of a conclusive reasoning on which has the higher center of gravity, besides that they are likely to be pretty close to each other. EDIT: Another measurement: the pedal hight of my EUC / bike is around 11cm / 13cm, respectively.
  3. For making it mandatory I would request solid data (i.e. several independent studies) that confirm and quantify its net positive effect (i.e. also take into account possible harm due to such regulation). Besides the frequency, one should also consider the seriousness of injuries for recommendations. Having said that, the first thing I personally put is gloves and I would put wrist guards next, if I had them.
  4. Really? How do you figure this? What does "much" mean? To my feeling my head ends up being higher when standing on an e-wheel compared to sitting on a bike. EDIT: just did the experiment. On my bike with very moderate seating position (in terms of forward body inclination) my head ends up about 2cm lower compared to standing on the e-wheel.
  5. Great points, I feel this is pretty spot on. I also agree with Chris Bruntlett, that which would equally apply to EUCs (and various kind of protections), except that I don't think we have developed this collective obsession so far.
  6. Mandatory safety gear is quite likely the death penalty for wide acceptance. sure, you can drown in a puddle, c'mon. It's not about what is possible, it's about what is probable. You honestly don't get it? Here is why (sorted by estimated importance): it takes time and is annoying to put on and off and take care of inbetween. Of course, if unicycling is a hobby of yours and not a necessary means of transportation, the ritual becomes enjoyable and almost indispensable (I know, I have been riding motorbikes for years). But there also is a reason why you would rather take your bicycle than your EUC for a 1km trip then. it is not comfortable (of course, if it's a hobby of yours, wearing it becomes a rather enjoyable ritual...)it makes you sweat more (not much of a concern in Finland)it messes up your hair and original clothes (remember, we talk about a means of transportation, not a hobby for which this would be perfectly acceptable for most people)it makes you look ugly (of course subjective, but certainly not the opinion of a small minority only)it reminds you that driving could be dangerous (regardless of whether it is or not)it might increase the risk to be involved in an accident (oneself and others become less risk-adverse)When I think of global acceptance of EUCs in urban transportation, I think of distances typically somewhat shorter than those taken with bicycles (which is, according to the studies, typically around 5km). I believe a few others have expressed similar views here. I don't think EUCs will become very popular for traveling larger distances than bicycles. This is the spot where pedelecs are more likely to succeed. This seems to deviate from the prominent use cases you have in mind.
  7. well, we talk about urban transportation and unicycles, so why would we look only at suburban cycle lanes for this purpose? I assume they looked at a place where cyclist go rather high speed (that's what they are concerned about), it's very unlikely to be representative as average speed and IMHO consistent with an speed average of 16km/h. I'd rather go with the data from actual studies with a protocol to data collection etc. than someones personal observations. What about you? If you have reasons to believe that the data collection of actual studies is systematically flawed, I am interested to learn about the flaws. I don't understand why that would or should be the case. It seems easy to accomplish that the wheel just doesn't go faster, period (OK, the involved control strategy must be a little more sophisticated, because loosing balance and increase speed generate the same input signal). Only if you lean so strongly and quickly forward that you get close to the limits of power flow, you will get a warning (e.g. via pedals or beep). Otherwise, and in any case, the wheel just does't go faster, regardless of pedal inclination angle. IIRC, this has already been implemented by KingSong for Germany to sell a perfectly legal device, where by law 6km/h are allowed on sidewalks for any device. Of course, you can remove the 6km/h limit with a few clicks in the app (which makes, of course, the EUC illegal then). I don't think a speed cap at 25km/h will be of any hinderance for the broad acceptance of EUCs (including guys like you, as you will just find simple ways around). Most current models come not even close to 25km/h anyway. There is anyway no choice, as not limiting the speed is no realistic legal option. You might be right, though your argument is somewhat flawed. If I am not mistaken, power-assisted vehicles that allow unlimited speed require invariably a drivers license. This seems in general a good thing and it won't change just because of the beauty of EUCs. Requiring a license for EUCs would be a significant hinderance in their broad acceptance, so limiting their speed seems to be the preferable alternative to me. With the risk to become very unpopular here: balancing all pros and cons including number of fatalities, a 20km/h cap is probably even better. It would not be my personal preference, but that's probably what the data would tell us when we would compare both scenarios (which we will probably never be able to do reliably enough), of course depending on how you balance saved minutes with prevented serious injuries and deaths.
  8. @esaj, I doubt that you are a representative cyclist, just as I doubt you are a representative unicyclist (most of us don't use a helmet, let along a motorcycle helmet). In my experience I need far more than 1/2 hour to travel a 10km distance with a bicycle in big cities. I googled this a little bit and found, that "the average travelling speed in Copenhagen is 16 kph for cyclists and 27 kph for cars" and A comprehensive review by Allen et al. examines bicycling speed in general (5). They conclude that bicycle free-flow speed lies between 6.2 mph (10 km/h) and 17.4 mph (28 km/h) with a majority of the reported speeds in the literature being between 7.5 mph (12 km/h) and 12.4 mph (20 km/h). Maybe your city is a specific case, or your data collection method hasn't been as rigorous. Wasn't it you posting the story talking to a cyclist who complained and then saying good-bye to her while pushing the throttle? Just one data point though. Another interesting set of slides on bicycle travel data for Portland, Oregon: http://www.slideshare.net/otrec/where-do-people-bicycle-the-role-of-infrastructure-in-determining-bicycling-behavior In particular: 80% of the trips are <=7 miles, 10% are >10 miles (slide 12), long trips are mainly done for exercise, not transportation (slide 13). Average speed is 10mph (exact same number as for Copenhagen), 4% of the trips have an average speed >=16mph (slide 14), my guess is that many of the "high"-speed trips are connected to exercise, not transportation.
  9. For the most part I admit that I find it difficult to follow. I agree that child seats and EUCs for carrying loads will not be the future. I also understand that bicycles tend to be able to go faster than EUCs. Yet, for the average speed and typical rides I think the difference is likely to be small, even almost irrelevant. I would believe that many cyclers go rarely if ever above 25km/h top speed. On the other hand, I couldn't think of any new technology that had repair shops or parking spaces ready even before the technology was introduced. Those usually come as consequences of the success, not as prerequisites. I haven't heard of any bicycle which has unlimited range (sure, the energy comes from a food store rather than from the electric plug, yet...). I would believe that 95% of all urban bicycle rides go for less than 12km one-way and most cyclers are not prepared to go further anyway. EUCs tend to be smaller and (in future) lighter than bicycles, let alone pedelecs. That they are easy to carry around inside and taken in trains or busses or cars is in my estimation a relevant factor. Another factor is that they are less exhausting to ride than bicycles. Yet, I would think that the typical one-way travel distance will be rather 2-5km than 10km. I agree, it will take one generation, and in this sense it is different from pedelecs which took a transportation spot in only a few years. EUCs won't become a widely accepted means of transportation for those who are now 25+ years of age. I don't think however one needs to fight an uphill battle to convince kids that EUCs are a nice toy to play with. If this is happening, it's not happening due to pushing someone or something, but because these grown up kids choose it naturally. I can't remember to have thought for a second that the Segway would play a relevant role in future transportation. They are too large, too heavy and too expensive, and any of these are not likely to change through technological development. In some way EUCs are the necessary changes to the Segway to become a widely accepted means of transportation. I wouldn't talk about revolution anyway, even though I could imagine that in 30 years from now more inner-city distance is traveled with EUCs than with bicycles. In any case, as someone has already said, it is difficult to make predictions, especially about the future.
  10. @EDL, you seem to suggest that driving an EUC is too difficult to learn to become a main stream means of individual transportation. Do you think that it's more difficult to learn than riding a bicycle?

    The difference is, I just feel that safety should concern everybody anywhere and must be as openly and frankly discussed as possible, while modding is for each individual to decide.

    @Chuts, I don't appreciate that you diminish safety concerns and even aggressively oppose them.
  13. Re EUCs for shopping:

    well, I guess then it's "ridiculous" thoughts which often prevent smaller and larger catastrophes in the first place ;-) To me it's common sense that people will make mistakes all the time. Therefore we try, by design, to keep the costs for making mistakes as small as possible.

    It depends on all kind of conditions and they might become loose only after 500km or 2000km or 8000km, or, if you are lucky, never in the life time of this EUC. The problem is that you don't want this to happen even once, ever. I guess, Loctite is your friend :-)
  16. I have similar experiences, obviously. It's mostly (though not only) middle-aged men approaching me wanting to know what this strange device is and how it works... That doesn't however mean that more than a small fraction even of this specific group will consider buying one. In my experience even many of them immediately find excuses why they can't have one, often because of their balancing issues... The good news is that even 1% of all middle-aged men is a huge market, so I am not at all worried.

    They better don't get loose while driving. I would have some safety concerns, as these screws can get loose over time.
  18. We might not like it, but to me that seems to be the very rational choice for the manufacturers. At this point in time, only a small fraction of adults will seriously consider to buy an EUC, while almost every kid who gets to know about them will want one. This will somewhat change in future, when most adults learned how to ride an EUC when they were ten years old.

    GW 18 5000km Trip

    It's a physical device subject to repeated acceleration forces, if not invariably used on perfectly smooth surface, weather, dust, etc. Therefore, sooner or later about everything will wear or break, the only question is how long it takes. So it seems perfectly valid to wonder what maintenances/repairs were necessary within 5000km. The most obvious is anyway the tire, possibly the wheel bearing...

    Recommendations? (IPS, Ninebot, etc.)

    IPS Zero is 14" however.

    Why would the Zero-260 and the Zero-340 have exactly the same weight?
  22. What is the future of EUCs? My guess: in 25 years from now EUCs will be a natural means of individual transportation, as bicycles have been for decades and, by now, pedelecs are at least in some places. For EUCs it will essentially take one generation: in a few years from now, most kids will want to have an EUC, many will get one, and most will at least have learned how to ride one. The rest will be history, determined by the usefulness/cost-effectiveness of EUCs as transportation device when these kids have grown up. I don't want to say that this scenario is certain (new means of individual public transportation could make it obsolete), but it seems a likely future scenario to me. Even significant architectural changes of cities might follow suit, which would indeed be awesome. My point: I doubt that EUCs will be just a fashionable trend for a few years and then forgotten.

    Kingsong 14C first impressions

    Except that the King Song is, as far as I can tell, about 2kg heavier. I know, you have your personal feud with Gotway, but I would not want to trade it for a much heavier wheel. Re. Gotway speaker volume: it would be (much) better if the volume were depending on the speed, but given the volume is constant I wouldn't actually change it (I don't drive under a constant speed warning, I just reduce speed). In noisy environments having a lower volume would be IMHO dangerous. The main cons in my books are the missing lights and the somewhat tiny pedals. Just my 2 cents.

    Recommendations? (IPS, Ninebot, etc.)

    If I am not mistaken Ninebot vs IPS is the choice between stylish design with all the accessories vs a purist but powerful wheel. Though, I guess, you have all the specifications yourself (I don't have any insider knowledge on these). The variety of choice for good 16" e-wheels under 1000 bugs is IMHO not that great. You might also want to check whether the max speed / speed warning settings suit your needs. Personally, I'd prefer to go, say, at least 18km/h without getting a speed warning.
