    Very excited tonight when I came home to a new Gotway box. Inside was my new whitewall 1300wh ACM. It's dark and cold outside so I just rode it up and down the street a couple of times, but WOW. I have about 800 miles on the earlier versions of the ACM, which was my favorite wheel. Now I don't know if it's my imagination (I don't think so), but the acceleration on this 84 volt version is mad. It feels scary fast, in a good way. I mean I thought the original ACM was a fast accelerator, but this is insane. Can you tell that I'm happy with this purchase Tomorrow I'm taking it on a 20 mile beach ride (on the bike path, not sand), so I'll fully flush it out. But I'm excited.

    If you want to learn riding backwards without practicing, here is how I did it: each time when I had to brake to a full stop, I tried to go an inch or two backwards before to step down, increasing the distance after a while when more and more confident... I believe it took about a month or so to get to a confident yard or two with no sweat involved.

    Starting to get a little more comfortable on the V5F+. The angle of the pedals is really hard to get used to, but I am more stable. The hardest part is getting my second foot in the right place, but I'm sure it'll get better over time. In the meantime, both my kids have gotten over the initial hump and are happily zooming around the neighborhood. They had a really hard time getting started. They did the balance by a wall trick, then I walked beside them for a while, but they almost immediately lost balance as soon as i let go. Most of the time, the remaining pressure on my hand is so light before I let go, but it's like they've come to depend on it like a crutch. Also, I think that having one side keep your balance may be handicapping them. I read a couple of tips about pushing a shopping cart and that kinda made sense to me. They'll be on their own and the balance aid is in front of them instead of on one side. I thought it would be easier to compensate front & back since the EUC already helps them do that. However, I couldn't just go out and steal a shopping cart and I couldn't let them practice in the parking lot of our local store. Luckily, we live in Florida and there are no shortage of walkers in garage sales and on craigslist. Purchased a used one with wheels for $20 so the kids could practice on it. After about an hour each, they got the hang of it and never looked back.

    @Mrd777 Sooo....., I'm not completely sure I'm qualified to answer the question I think you are asking. What I think you're asking: Which one do you like more, the 2017 1200W KS-18B or the 1500W MSuperV3S+? (i.e. the latest models out, both I have never owned) It seems important to distinguish, as: for Gotway: the 67.2V operational MSuperV3's (personally never rode) do not exactly drive like the 84V operational MSuperV3S+'s (personally test rode) and for KingSong: the 800W KS-18A (personally own) does not apparently drive like the newer 1200W KS-18B (personally never rode) I can speak on the 800W KS-18A mkII, as I own this wheel and have ridden extensively. I can speak on the 1600W Monster, as I own this wheel and have (now) ridden extensively (don't think you were considering this model). And I can speak on the 1500W MSuper3S+ from a few hours, test-ride experience perspective only (not enough IMHO to intimately and definitively speak on the idiosyncrasies of an EUC). * And also, the Monster rides different enough from the MSuper3S+ that you cannot infer the same ride even within the same GotWay family line (main difference, besides the implications of size/weight: Monster pedal response / resistance is significantly harder than the MSuper3S+ pedal response / resistance >> both wheels set to the hardest Sports mode) As I have no direct owning experience of either current models, ..... Some observations partly based on this forum / partly based on my experience of previous generation (800W KS-18A) and sister models (Monster/MsuperV3S+): Pedal Response / Hardness: As @KingSong69 has continually stated on these forums, the newer 1200W KS-18B carries a harder pedal response / hardness / resistance than the previous 800W KS-18A (which was not the softest out there to begin with). The MSuperV3S+ in Sports mode, on the other hand, is basically the softest pedals I have ever ridden on an EUC bar none (and I've ridden every brand). Pedal hardness to begin with is a matter of personal preference, but if you are looking for the same brick hard response as your new V5F+, the KS-18B will be much closer than the MSuperV3S+ Not sure what you mean by "agile acceleration", so let me break things down in comparison to what you know in the V5F+, as I own and intimately know that wheel as well: V5F+: I would classify the V5 as most like "agile acceleration", as acceleration on this wheel is a consistent combination of torque-y-ness and ease across all its speeds, both accelerating from rest, and accelerating across the whole range of it's speed. MSuper3S+: Acceleration here for the most part stays true to the Gotway signature acceleration: very floaty and effortless, very little resistance feeding back on your pedals while summoning a tremendous amount of power. The only caveat here is acceleration from rest or accelerating uphill. If you don't know any better, you might be hesitant to lean harder in these situations (which was me previously) due to overlean cutouts, which most other EUCs would be subject to. However, the 84V Gotways (ACM 1300WH, MSuperV3S+ & Monster) I believe have better safeguarding / tuning as a result of the higher operational current (my theory), where you can lean extra harder than the average EUC and summon a tremendous amount of power for these situations. I would define these accelerations more as "power accelerations" than "agile accelerations". (based on my Monster experience and corroboration with a fellow NYC MSuper3S+ owner) KS-18B: I can't speak directly on KS-18B acceleration here, but, FWIW, a.) my 800W KS-18A acceleration is no slouch (falling somewhere in the middle of the V5F+ and MSuperV3S+ in terms of torque and ease), and b.) the newer 1200W KS-18B is supposed to offer more torque. Speed: MSuper3S+ reported safe max speed: 45km/h || KS-18B max speed: 40km/h ...... it is what it is. And now, some annoyances to consider: Quality Control: There are already 3 concrete reports of MSuperV3/V3S+ gyro wires disconnecting due to bad solder jobs. This alone would give me pause in purchasing an MSuperV3S+ (to be fair, most owners have not experienced.... yet), and these stories are always in the back of my head while cruising on my Monster (I've already committed to monthly Control Board checks myself). KingSong, on the other hand, while having had their own share of QC issues, have never had QC issues of the disturbing kind like the aforementioned Gotway MSuperV3/V3S+ gyro-soldering issue. Cripple mode: Both enter crippled, reduced speed mode way too early IMO, considering both battery packs are 1+kWh, but the current KingSong crippling is way way too early at sub-50% threshold (Gotway is sub-20%). Not a dealbreaker for me personally as I usually don't ride far below 50% on any wheel if I can help it, but annoying nonetheless. Beeps: Not mentioned much, but I find the lack of user-settable speed alarms on the Gotways annoying, unlike my KS-18. I personally don't like to ride with the phone apps, so like to custom set the speed alarms on my KingSong more as a speed indicator rather than a warning. (I believe Gotway is 2nd alarm = 34km/h or off, 3rd alarm = 80% power, no off). Also, of note, while both companies offer tiltback, I am too scared to set on my Monster (currently off) due to reported cutouts from 62.7V operational MSuperV3 riders setting their tiltbacks too high (30+km/h). And, on the KingSong side, while tiltback works great, I would love the ability to turn it off, as too much tiltback occurrence seems to throw off calibration faster. Unfortunately, no one on these forums, including me, AFAIK, has extensive owning experience with both the KS-18B AND MSuperV3S+, only one or the other. Also, because of it's form factor, I personally don't really regard the KS-18 series (taller, rectangular) as a direct comparison to the MSuperV3 series (circular). The MSuperV3 handling compares better with other, circular EUCs, like the majority of 16" EUCs out (Ninebot One, InMotion V8, etc), while riding the KS-18 series, when you really put the time in, handles and turns differently. If it were me, I would wait both to see if there are more MSuperV3S+ incidents, and what the specs turn out to be for the rumored due-out-this-year 2 new KingSong 18" models: KS-18B mk3(?) revision and the new form factor (rumored to be shorter) KS-18 (I myself am waiting, hoping KingSong makes the move to 84V operational as Gotway has). I don't think you can really go wrong with either wheel, but I also don't think these wheels are the straightforward, head-to-head comparison you are assuming here; really depends on your priorities, preference. Personally, I will stick to my current 22" Monster, and possibly upgrading (spec dependent) to the next KS-18. Sorry for the long drawn-out non-answer~ Also, if you're on FB, DM me your user name if you wanna be added to the NYC EUC group chat there; a lot of useful knowledge shared by local riders, as well as the occasional group ride.

    As a Star Wars movie machinery in today's reality For fast driving, I like sitting in this wheel ! Then he seems very stable . I did not great here though wery fast because I've already felt the functioning of the speed limiter ! To limiters fast accelerating throws a very very strongly back !!! It may even throw you away ! I am, however,very very pleased with this wheel ! Here a small video : https://youtu.be/cqPki7qFuLk

    Just swapped my shells for the GotWay soft touch Blue. Still need to paint the handle and pedals flat black, but I'm liking how it's coming along. This might be the only GotWay Blue V3 820Wh in existence. 😉

    I came off the other day ( yeah, what's new, right?!) but it got me thinking. Here's what I wrote in another post: the other day I was about to cross from one smooth surface to another, on the same level. No biggie right? Wrong. You see there were women ( why did it have to be women?) walking on the other smooth surface, so I had to cross further down, behind them near where these parallel surfaces ended, and not in my usual spot, somewhere nearer the middle. at about 15kmh, what I didn't notice was that these two level surfaces WERN'T level near the ends, only around the middle. Well you can all write the next bit yourselves, can't you! At 15kmh the wheel hit a 4cm edge and stopped long enough for me to start my low level flight. I did manage to run it off, despite being old and out of shape. The women, who had just passed through, were not impressed, but I got no sympathy either, boo hoo. 😉 Maybe I should have hit the dirt hard, instead. At lower speeds I might have made that unseen edge with a huge wobble and a lot of flapping, but at 15kmh I was a runner before I even knew it 🏃🏻... End quote here's Lassies standing over the true, level surfaces in an area I have crossed several times before: now, here's Lassie at the not so level part: notice leash 3.0, and in the background is the beach where I found it. i was crossing from blue to grey at about a 45deg. angle more or less in line with this photo. this is where I ran off my dismount: See that sandy patch, with the tree and boulders? That's were I finally stopped. if that had been a cliff, or a wall, or a parked car, or a mother pushing a stroller with babies in it, if, if, if... we often ride in a straight line, down a sidewalk or a bike lane, etc, so the next 2 seconds of our journey is like the last two seconds..I.e. Straight infront, no drama. But if we weave, or slalom, or are changing direction; even on an arrow straight path, the next two seconds changes every, eh.. two seconds, or so. So now, if we come off, (and coming off is ALWAYS an option) where will our momentum take us? Out into a busy street?over a cliff?into a wall? Into a tree and or boulders? in this example, I was lucky; my run off path was mostly clear. But if that tree or the Boulders were 1m this way, I would have had a vertical face plant, or banged up wrists or both, like the bike rider with a front wheel for a nose ( see recent post) when I was learning to fly ( real aircraft) and when I flew paramotors, being aware of the terrain, and knowing where to do an emergency landing (at any given moment) was part of the drill; and staying out of situations that afforded no safe "out" too. I suggest, that we adopt (if you have not, already) this, "where will (my face) land if I come off right now" mentally. I'm not saying to wheel in fear, just to build it into your routine, behind the scenes, thought process.

    Where the rubber meets the road, it seems, doesn't get enough love here. So I thought I'd start a thread to share opinions about tire pressure, maintenance, etc. (starting with some of my opinions). I find tire pressure to be one of the most important components of handling and ride, and I'm a bit obsessive about it on my EUC's (probably carrying over from motorcycles and bikes). There are three things that make tire pressure a challenge with EUC's: EUC's only have one tire, low pressure has a direct impact on ride, and tire failures are unforgiving EUC's have unique bent valve stems that make it hard to find inner-tubes, and a pain to fill (you just don't want to do it) EUC tire pressure is a bother to check compared to any other vehicle, because the valve stems are hidden in the EUC cavity, and difficult to attach to a pump ... and there are probably other things. The net result is that you want to maintain the tire, fill to pressure and forget it. To that end, I've Slimed (https://www.amazon.com/Slime-10056-Tube-Sealant-oz/dp/B003V9XYNW/ref=sr_1_2?ie=UTF8&qid=1487706156&sr=8-2&keywords=slime+bicycle) both my V8 and Zero. I used about 1/3rd of the bottle on each one. There is no effect whatsoever on the feel of the wheel, and I think it provides a certain security. In Chicago, I can take my bike into any number of convenient shops to buy and install a new inner-tube; but the same shops would just draw a blank with an EUC, and the inner-tubes are hard to find. Best to maintain what you have. I like to keep my tire pressure up at 3 bar (~44 psi). The sidewalls of my V8 and Zero tires both recommend 40-65psi pressure, and the V8 comes from the factory at 2.8 bar (~40psi). So for me 3 bar seems the right pressure, and both wheels feel good at that pressure. It's a real bother to fit a pressure gauge on the valve stem because they are bent against the wheel. I almost never get a seal on my gauge without several tries. So instead, I pumped the wheels up with my Lezyne pump (https://www.amazon.com/Lezyne-Steel-Floor-Drive-Black/dp/B005UND3CY/ref=sr_1_3?ie=UTF8&qid=1487706504&sr=8-3&keywords=lezyne+pump) -- I recommend Lesyzne as the absolute best bike pump on the market -- and then put a Gozens 44psi cap (https://www.amazon.com/gp/product/B01HRIKIY0/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) on the wheel. That way, I can easily check the pressure at the start of each ride. You do need to buy the Gozens at a particular pressure (BTW, they have bluetooth systems, which I think are a bit of overkill) but you get 4 of the basic caps for $9, so NBD.

    I've just been leaving my V5F+ balanced on the built in "stand" in the garage. When one of my kids accidentally knocked it over (no damage), I realized I had to do something to make it a little more secure when not in use. I had some cable clamps that I figured I could screw into the existing hole on that plastic edge. Rummaging about, the cross bar on those wire shelves fit nicely in the clamp. I cut a piece that won't stick out too far, smoothed it out, rounded the edges, and covered it in heat shrink tubing. After finding a longer screw to accommodate the cable clamps, I screwed everything together. Also added the pad which acted as another stabilizing point. Took about 1/2 hour. I may have to find some black cable clamps, but it'll do for now.

    This is an experiment. Lately I've been recording my rides with a Garmin 60CS. If you have Google Earth installed you can view my recent 43 mile ride around some local Los Angeles rivers and paths. I want to accumulate a large collection of EUC friendly routes to ride Southern California. As people enter the sport in my local area I can point them to a collection of rides to try for themselves. If you have Google Earth installed you should be able to download the file, launch it, and Google Earth will take care of the rest. 20170225 - ACM ride on Coyote Creek and San Gabriel Rivers.kmz

    Commercial airline pilots are trained to know at all times where the nearest emergency airfield is so they don't have to fumble with maps when something goes wrong. I've walked off plenty of times in front of people, and riding a unicycle looks so absurdly difficult that people respect you...they aren't at all thinking what a dunce you are. With a helmet and elbow/knee pads it looks like a dangerous endeavor and you're treating it like a dangerous endeavor. The perception is mad respect for a person that takes such a risk. My personal perception is that electric unicycles is less dangerous than bicycles because bicycles are usually on the road where they get hit hard by cars whereas unicycles are usually ridden on the sidewalk. I almost always redo the thing that forced me to walk off. Those are the experiences (the edge cases) that will bite me in the future. I had a sunken sidewalk yesterday that I walked off; I saw it and knew it was trouble, but I went for it with predictable results. I walked the unicycle back, and tried again, and was walked off in the same way. It took me a few tries, including one where I walked the unicycle across the edges just to understand the dynamics of it all, and finally I was able to go across that questionable pavement in a smooth manner. Also survived an attempted mugging by a pack of little girls. One had her grubby little hand on the handle of my unicycle before being pulled away by her shocked mother. And I thought we lived in a good neighborhood full of unemployed white married women, but no, vicious brutes abound the sidewalk ready to ambush unsuspecting unicyclist. Be careful out there.

    UPDATE: After speaking with Tina(a KS representative) she told me to kindly speak with Carey (engineer at KS) since I spoke mandarin we had no language barriers. All comments were thoroughly explained to Carey and he tentatively listened and responded. 1. Speed should not be reduced We can increase the speed to not allow any speed drops after 50% for KS16-a/b/c Available in the next firmware update v1.25 to be made AVAILABLE TODAY (Feb 27, 2017) HOWEVER it is not possible for any other KS-14 and KS18 wheels due to the safety factor. Carey went on to explain how the wheel would not withstand aggressive accelerations if the speed limit drops. 2. Customizations on Alarms Carey understood and will try to implement these. However Alarms 1 and 2 can be turned off when set to 0 3. Light setting should save The light setting can not save due to the way the motherboard on the wheels are engineered. However it is possible for the newer KS wheels (KS16s). For existing KS16 wheels you may turn on the bluetooth and if the lights are on quickly push the bluetooth button (whilst its on) for around 1 second to turn off the lights. 4. Lights locked in place/ not alternating Carey said this is doable and will be put out soon. 5. Wheel does not "spin out" when lifted off the ground Not possible due to the engineering of the trolley handle. Because there is no sensor for the handle the wheel can not come to a stop when lifted off the ground. 6. More customizations on pedal tilt Was considered 7. Bluetooth Password Understood by Carey 8. Rename KS device name Understood by Carey 9. Headlights Brighter lights are available on the newer KS wheels More Flashing options for existing wheels will be considered 10. Firmware updates consume more power Carey said that this is definitely not true. It may appear as such on Wheellog because the wheel has faster acceleration due to the new V1.23 update.

    There're so many recent posts here it's too time consuming to answer individual points, so I'll type generally. use a loosely held strap; prevents: run always, bad crashes, scratches, attacked ankles ( you can lift wheel off ground killing its energy source) bad back from constantly bending down to grab the wheel, etc. always wear full protection, especially wrist guards and a helmet. Never mind the dork factor. Any injuries you sustain now will be with you long after your perception of people laughing at you. Besides, they are strangers so who give a flip about what they think of you. I'm still nursing a wrist injury from October (with wrist guards) so imagine if I wasn't wearing them! Try to practice in a secluded place. On lookers are not good for your practice karma. don't try to master stepping on, one foot at a time, until you can ride for hundreds of yards at a time, with ease. Use a mounting aid, like a wall, a fence,or lamp post; anything you can lean on to get on calmly, placing your feet properly. Plan your training and rides around these mounting aids. Stepping on, unaided comes much later. You guys are trying to sprint before you can crawl. if you need high heeled boots to move forward, or you can't maintain forward movement, try standing up straight. Or possibly your feet are too far back, move them forward, simple as that. No one else needs heels to wheel properly. don't start on grass, or even ride on grass, mud gravel, or dirt; the smoother the training surface the better. Grass is still hard to start on for me and I ride on every surface, including quick sand( but not very long 😜) grass also hides small holes and dips that will throw you off, I know, I've seen me do it. No, there isn't a lot going on in our heads, once it clicks. We "clickers" talk, text, listen to music, make/take phone calls, sight see, take videos., weave, slalom, dance, eat, drink, mountain climb, do tricks ( not me). None of that would be possible if our minds were preoccupied with wheeling. It just happens, and you absolutely stop thinking about it, trust me/ us. You've just got to put in the hours, but put them in, in the right order. I had over 200km before I even tried to get on Unassisted, and about 100km more before I got it down, and I'm still not good at it at 900km, a bit hit and miss. Once you can ride, the other parts are easier because, if they succeed... You can ride away, and not just fall off. It's much less exhausting that way, and you can start to enjoy this aspect of the experience, even though you can't get on unassisted, or turn, or , or, or... All work and no play makes Jack a dull boy. What's the point of mastering getting on if you can't ride more than 3 feet? Get riding down first, then add the launching unassisted and stopping gracefully ( anyone can stop without grace), and turning, wow, that was a challenging week. Dont believe there is only one right way to do any of it. One solo wheel training video says the way to turn is to twist the wheel left and right. Nonsense, that is only one way to turn. There are several, and they will all come to you as you discover them, while riding for hundreds of yards at a time, over hundreds of km. the distance mounts up fast, believe me. This is the time when you can try little things, or more accurately little things try you. Those many "oh shit" moments, while trying to stay on in a straight line, eventually add up to one giant " I get it now" moment, that is called the rest of your wheeling life. There was a time when if I looked left or right, I fell off. Now, my head's on a constant swivel enjoying the view, watching my path, planning my route, etc, even almost all the way to my rear as @Mono suggested was possible, or riding with my eyes closed, or looking straight up at the sky, also @mono suggestions ( I think he's trying to kill me). Any experienced rider here can do the same, and most of us felt frustrated and defeated, like you do now, at some stage. Some picked it up fast and some not so fast, but everyone who stuck with it gets to enjoy low level gliding, when ever they want. it will come, trust us. One day you will wonder what all the fuss was about. personally, I really enjoy making it look completely effortless as I wheel past gawking crowds, down by the beach. I clasp my hands in the small of my back, check my phone, admire the scenery, ride impossibly slowly, change direction without seeming to move anything, zoom off at will, stop and admire the view, continue on my way like it's completely normal. Its a lot of fun. Some of them must think it's some kind of magic. Which it is, in a way, a magical mystery tour, is coming to take you away. What are you waiting for? oh, and never show off ( as in hard acceleration, hard stopping, etc) it always ends in a humiliating and often painful face plant. Just riding one of these things with ease and grace, is all the showing off the "walking dead" need see to be impressed.

    I got my VF5+ from ewheels yesterday, and was pretty confident I'd be able to hop and go. Instead, this seems impossibly, incredibly difficult. You don't realize just how difficult it is until you're standing next to it. It is, improbably, just a wheel with pedals, the ultimate simplistic form of a vehicle, yet it cannot work with a very sophisticated set of sensors and computers working for you. I'm in awe of this wheel and the technology. Apparently the only way I know of dismounting the vehicle is running off it (all learning on grass). Hopefully that habit can be broken. I don't know if unicycles can become mainstream. Not one person in my office wants to have a go on it. Their reaction is more akin to incredulous horror. After about twenty minutes of practice, I got out my dress boots; the extra heel height and the rigid ankle high leather allows me to place the weight more on the toes while keeping the entire lower leg locked. Also the heavy leather protects my ankles from the pedals during falls. The boots helped a lot--just like shifting into a higher gear. It's remarkable how the human mind works; something so difficult becomes, after a while, not so bad as the human mind adjusts.

    Dispair in the early days was normal for me. Two years into this thing of ours, I barely give it any thought at all while riding effortlessly. That came much sooner than 2 years, but riding with some confidence did take me close to 2 months. I was a slow learner. PS. It is worth the effort.

    I used training wheels in the beginning with a strap, then got rid off the strap, then got rid off the training wheels. I practiced in a tennis court, hanging to the fence wall for balance with all the safety gear. That is helmet, wrist guards, shin pads, knee pads. When putting your foot on the pedal, think of putting your foot on a foam cup without crushing it. Someone here said this, not me, but that was a good analogy. At some point in the beginning you want to give up because it is too hard to balance no matter how much you put effort in it. but DON'T. If we all can do it, you can do it. It's like learning to ride the bicycle all over again. It's hard at first then it's a second nature.

    That's right, and it weighs only 98g. Yet I virtually never carry it with me, even when traveling. With slime, tires lose virtually zero air over time and I haven't had a flat in 4000km.

    I have no problems pumping any of my wheels using a rather smallish conventional bicycle pump which tightly attaches to the valve by moving a lever. It is even slightly easier than pumping my foldable bicycle with 18" tires. Pressure choice: as high as necessary to never get a puncture or rim damage due to hitting curbs, potholes, etc., but not higher (for comfort). I am also using slime in all of my wheels.

    I don't get it why some people try to outlaw all currently available EUCs, including all their natural future technological development and improvements. I don't see so much wrong with any and all of the EUCs that we can buy now. Of course, all EUCs can and should be improved and regulated (say a speed limit and a deceleration requirement), but I would rather prefer to see evolution than revolution. I have the vague suspicion that someone not yet in the market tries to overtake, monopolize and profit big time (as the thread title suggests). I am all for measuring and certifying reliability, however dictating the technology how to achieve it (redundancy) seems to be the wrong approach. And that losing the bell means to push or carry the EUC home isn't in my list of (even remotely) relevant safety priorities either. On the positive side, I have doubts that a legislation outlawing all currently operated and available EUCs is likely to succeed in those European countries where EUCs are currently regarded/treated as legal anyway.

    I Will certainly continue to update what I experience with degradation of battery life over continued use with the other charger. To me the extra range is worth replacing the battery completely down the road, but I know others may not be of the same opinion, so I won't encourage it. That's a choice only people can make on an individual basis.

    The fact that one guy can ride in the water for a few seconds is something, but it doesn't meen that all the units are water resistant, I would say the ACM does resist to a little water or rain, but I wouldn't trust it, due to the way it is built, to resist a storm for example. IP55 pretty much gives you the assurance that it will be able to resist to all weather conditions. About the USB port, it can be useful to charge your phone, I don't use it but it's not a weak point because unlike on the kingsong products, it is well protected, water can't penetrate inside if it's closed

    @Duf nice trip footage to work and back! Regarding the sore legs, have you tried shifting your feet slightly more forwards on the pedals? Not a lot but a little might help. I try to do heel toe heel toe movements on each side as well kind of like when you are standing for a long time. I think every bit helps to keep the blood circulating. Just be careful when you toe to maintain good contact on the front edge of the pedal. I'll also do slight side foot tilts in addition to slaloming which help a little. I'll have to work on one leg riding as that surely will help during longer rides to get all the pressure off the other foot I think.

    Well, copying is pretty rampant in China, but it's not all bad design-wise, check out Rigol Technologies's products for example, although they still probably don't compete in the very high-end professional equipment, but they have at least very decent low- and middle-end stuff with excellent price/quality -ratio. Not that I can really tell, precision circuitry and RF-stuff is still mostly just black magic to me, but I've seen enough teardowns and comments that they can't be all bad design-wise. "A 4 channel, 12 Mpts memory, 30 000 waveforms/second, intensity graded scope of this quality for around 399 USD/299 EUR/235 GBP (plus tax) is nothing short of astounding, even before the hacking possibilities are considered. " Probably other similar "high-tech" companies exist in China, of course there's also lots of the "not-so-good" or just plain awful -variety. But probably it's the same elsewhere too... Wired released a pretty interesting document on the Shenzhen "hardware scene", it's not only copying but (at least in part) more like "open source" approach to hardware (although, to be honest, yes, they do copy a lot of stuff that they shouldn't be ): We examine the unique manufacturing ecosystem that has emerged, gaining access to the world’s leading hardware-prototyping culture whilst challenging misconceptions from the west. The film looks at how the evolution of “Shanzhai” – or copycat manufacturing – has transformed traditional models of business, distribution and innovation, and asks what the rest of the world can learn from this so-called “Silicon Valley of hardware". Also, it's not always just that it's "bad design", it's cheap design. The designers' hands can be tied by demands that the product must be "economical" to manufacture, meaning they have to pick cheaper and lower quality components and make compromises in quality vs. price, or that the product must be designed fast, leaving less time for prototyping and working out the quirks.

    @nomad great video, what a long trail that is. And most of it right on the edge of a steep dropoff. I noticed the white Kingsongs had no handles and wondered why until the part where the rider was standing on top of the wheel. One interesting part was when the rider went down a 35 degree hill, turned around and with only 2-3 feet level ground to get started, went back up the hill. Good power from the Kingsong. It looked like something the military might use in the future, small team riding silently at twice running speed for miles.

    Slime is pretty light, and you'd think it's viscous from the bottle, but once you start pushing it into the tire, it flows very smoothly. I think the spinning tire just spreads it out evenly over the inside of the inner-tube, so there is never going to be a balance problem with the tire (the centrifugal force would see to that). I'd read that Slime's green (denoting it is eco-friendly) tire sealant is composed of fibers, binders, and clogging agents that build up and intertwine to seal punctures in inner tubes and tires. It's based on their branded Fibro-Seal® Technology which they license to others apparently for roof sealants and such. It's produced by the Chicago company Illinois Tool Works. The bottle says good for two bicycle tires = 3 unicycle tires (my guess).
