    @Scatcat Thank you very much for writing this advice and spent a lot of time. Updated firmware/app, where you can set the last alarm at a percentage of power. Like 80% of maximum available power. Audible temperature/overcharge/overcurrent alarms, to avoid stupid accidents. These two have been resolved. 2.5" tire, to heighten stability and comfort on long runs and in terrain. MOSFET 12x247 (Wierzę, że istnieją 6x247 teraz, ale nie sprawdzone osobiście) Design space is not enough, can not change.

    I think I just ran across a "Dudley Do-Right" type, or bored. Either that, or most cops don't know/care enough about the law. Either way, just let glide baby! Let a man glide!

    Don't ask me! I am barely cognizant of my current surroundings and state of mind . We love Amar'kans! Heya neighbour! We might not see eye to eye on all subjects, but that's fine. Trump is always entertaining to watch on the news to see what comes out of his mouth/Twitter/policy planning next. Makes for good TV! @Marty Backe is fine just the way he is. He don't need no stinkin' spelling, grammar, or grandma checker! I don't expect that everyone will always get along with each other on the forums, but I hope that most of us get along with the majority of others in a mature, respectful manner. We're all the same flesh and blood and share common interests. Why not make an effort to be friendly I always say? To each their own of course as not all Canadians are really Canadians.

    I knew a guy who was into processor duels. Always had a chip on his shoulder.

    Yes really helps a lot, I once wrote an entire user manual for a multiplexer in which I repeatedly mentioned "duel processors" Strangely enough my spell checker just didn't notice it, but my students sure did ?.

    I had a Monster Energy drink this morning & so embarked on the ambitious project of completing the 'Choosing the Right Battery Pack' Blog article. Euphoria has since worn off, will adding additional text tomorrow... https://www.ewheels.com/choosing-an-electric-unicycle-with-the-right-battery-pack-for-you/ There are now dozens of different battery cells being made by the big manufacturers LG, Samsung, Panasonic, & Sony. For use in an application like an Electric Unicycle, the two qualities that make a particular cell more suitable over another are it's power output (Amps) & energy density (Ah). Until fairly recently there was an inevitable trade-off between either high-powered cells (e.g. Sony VC3/A123) and energy dense cells—there's the example of the Panasonic NCR18650B, which had capacity, but could only deliver 2-3 sustained Amps. What has been one of the key drivers in powering the Personal Electric Vehicle revolution, is the introduction of >3Ah (>10Wh) batteries which can ALSO capable of sustaining high currents above 10 Amps. The Battery cells which are most commonly found in Electric Unicycles are shown above. Although lacking in capacity & somewhat outdated, the Samsung 22Ps are still quite common for many Self-Balancing devices because the cost per cell is very low. Ideally, a smaller battery pack (<32 cells) would have more powerful cells, like the HG2 (found in our small 12" IPS a130s) or the VC3 (used in the Solowheel) to provide the necessary sustained power even, if the speeds are modest. Because the cells are nearly all capable of the same 10A power output, the calculation then becomes one of how many battery cells you need for your requirements of speed & Rider weight—hill climbing expectations are also important factor for power, but to keep it simple, it's has not been shown here. These figures are probably on the conservative side, but for a device where getting enough power is the vital for survival, erring on the side caution is preferable. This next illustration shows how the battery cells are configured, their capacity & power outputs in several popular Electric Unicycles. There are two defacto standardized voltages for most Wheels: 67.2v, which is comprised of 16 cells in a series & 84.2v, with 20 cells in series. Good arguments exist for both voltages, but for higher performance Wheels, the increasing trend is converging towards the higher 84.2 voltage. This is mainly on account that motors of higher voltages are capable of higher speeds with better brown-out safety margins.

    I think the only time you would consider any wheel as "too fast", Is the day after you face plant on it. Or possibly the split second someone comes around a corner and you just know you are not going to be able to stop in time. And there by hangs the formula for whether a wheel is "fast enough". How much protective gear do you want to be using when you ride and how open are the paths and trails you are going to be using. If you will be riding in wide open spaces and willing (IMHO) to wear pretty much full motorcycling gear then get a faster wheel, if not, in my opinion you should find 30km/h plenty fast enough. What I do know for sure is you will find 30km/h significantly faster than 20km/h.

    I sure wouldn't want to have to tame multiple assailants, or a zonked out druggie, or a guy with a broken bottle or knife with only a baton .... and of course all of Britain is famous for knife crime. A knife is as good as a gun in many situations. I think asking police to put themselves in mortal danger for what could otherwise be fairly routine arrests does them a disservice. And i wouldn't be surprised if it results in what we see here in America, too, sometimes ... police often don't come to violent scenes for a long time. Safer that way, or just pure coincidence? And more importantly ... safer for whom? Don't give people the tools for the job, you can't be surprised if they don't do the job. On the other hand, police in the USA are so reluctant to engage in a scuffle that tasers and taser use have become ubiquitous. If you give people a weapon but give them tremendous leeway in how to use it, citizens can become targets and the police an occupying force rather than people who are there to serve and protect ... two enormously important words fundamental to the very concept of policing. If the type and severity of violence one can lawfully inflict on the citizenry increases, oversight and accountability should increase in tandem with it. I don't believe it is in the public's interest to guarantee the police an overly safe job. It is an inherently risky job partly because of the restraints necessary to keep policing itself under control. But I don't believe we should give police no option of last resort -- that is, no gun to protect themselves against the situations that they may encounter. And I think people in general tend to underestimate the deterrent effect of a gun. It won't always have that effect and shouldn't be used as a crutch in situations that might be more safely defused. But I believe a gun's threat of serious force is capable of bringing order to some situations without it ever having to be drawn.

    Mosfet can be upgraded to IRFP4468PBF, 2 mohm vs 3.7 mohm for existing version. Thicker wire between motor and battery should be an easy improvement for heat reduction. Using better capacitors will also help. Should be possible to make all those improvements for maybe $20 per unit.

    I shop at Walmart Neighborhood Market almost every week, and I place the wheel in my cart while in the store. The store personnel have always reacted very positively. Customers say things like, "I saw you roll into the parking lot! How does that thing work?" I recorded one of my grocery trips:

    Best advice IMO, is the dominant foot on the pedal, and just take a step with the grounded foot, but don't mount. Just take a step and let the mounted foot move forward that tiny bit till you set your grounded foot down. Repeat. Similar to pushing off on a skateboard (very lightly), just take a controlled step with the grounded foot. Forget mounting for a while and simply learn to have one foot mounted, while taking one step after another with your grounded foot. What this does is train your body and dominant (mounted foot) where the balance is in tiny bite sized chunks. You'll find you can take a longer step before putting the foot down and longer. Eventually, you will be amazed to find you can raise the grounded foot and basically take all the time you want to place it on the pedal because you can balance so well with that dominant mounted foot. You'll be dong a smooth, beautiful controlled mount/dismount in no time, but you just have to train a bit. Once the ball gets rolling though, you'll progress in leaps and be trying to ride backwards, trust me. Gliding is simply too fun, too addictive to stop once you get that first controlled ride-feel in your bones. Edit: Oops, Carlos covered it earlier.

    Me too, though I'm too ignorant to share in the knowledge. That leaves me just appreciating the enthusiasm! Now if you folks were discussing things on the level of rolling some dough into a ball or stirring sugar into iced tea, I could follow no problem.

    That's a pet peeve of mine. I ride lots of trails and sometimes a person will say that I shouldn't be there, like I'm some big nuisance. Meanwhile I have to spend time dodging horse crap on the trail - not pleasant when you mistakenly roll over one, and particularly bad when you're riding an MSuper or Monster (you fellow travelers know what I'm talking about).

    This thread is a wealth of knowledge. I too am a new user and have found my beginnings to be quite difficult. I started by taking my wheel to the local best buy parking lot(out of business) and riding along the walls so I could start without mounting. After about a half hour got to the point that I could go back and forth across the parking lot(maybe the length of a football field) and very shakily make a super wide wobbly turn and return to the starting point. The next day the board blew up on my MCM4 and this totally stopped me from doing anything. Took a week to get the board back and installed. After this back to the road(or driveway in this case). Started circling around the cars in the driveway and just trying to perfect speeding up and slowing down. Got to where I thought I was pretty good and the next day proceeded to the street. I could successfully mount(very shakily) and go a short way down the street(very shakily as well). Got a little too confident and started increasing my speed(not recommended). Anyways did a full face plant on concrete after losing control going down a slight hill. No major injury from this except my ego and my wrists have been sore for a week from catching myself. Following that was going slightly uphill and lost control again. No face plant but stepped off the wheel wrong and must have pulled something in my right calf. I couldn't walk for a day and have had soreness and pain ever since, so I took a week off. Now ready to get on again(I'm sure I forgot everything by now lol) and it rains every day =(. Here's to figuring this thing out without breaking my leg first! Thanks to all who have helped in this thread.

    I think he didn't like my comment regarding pushing wheels past their advertised speed, so he hit me back because of some spelling errors. I'm going to have to use a spell check now because I don't want to come across as an imbecile. No worries, it's all in jest

    I thought this forum was immune to criticisms of spelling/grammar/usage, etc, and focused its energy instead on ideas and constructive conversation, for the most part. This is the first criticism I've seen based on spelling since I've been a part of the Electric Unicycle Forum for the last year and a half or so. I hope it is the last, since it adds very little to the merits of a discussion, unless the spelling/usage error makes the question or a response impossible to understand.

    Dear @LanghamP, I guess it won't surprise you that I beg to differ. Being German, we tried a few of those recipes of separation inside our country with infamous consequence. We're cured from that (at least I desperately hope so). We also went through the experience of getting rid of a border lately. Before you protest: both East and West Germany were home to an entire generation of peeps growing up in isolation from another. Same language, but considerable differences in social behavior, economic rules and things taken for granted. Happy to say: we're pretty much over that, too, albeit many experienced a bit of "friction warmth" to get there. When economic conditions required it, Germany saw a highly requested and welcome influx of "imported labor", i.e. Italiens, Portuguese, Greek, Spanish and Turks added to the continued presence of allied military in country after WWII, many of them with family and kids. We have been an immigration country long before it was officially recognized, those "guest workers" came here to stay. Could we have managed integration better than we did? Of course! But I yet have to be robbed or shot at as a result from mixing so different cultures in country. Then, with considerable contributions by "The West", Afghanistan, Iraq and Syria were bombed to pieces, displacing millions. About one million of them found their way to Germany. Some dumb like bread, some highly educated and anything in between. Quite a few traumatized and presumably several hundred incurable fanatics. No argument there: that's a risk. Unfortunately, the "German generosity" towards refugees which made news in 2015 trickled away half way in the process. We let'em in, but now we 'administer' them with all the red tape, German bureaucracy has to offer. Most are not allowed to work, constantly threatened with deportation to the countries they fled from, sheltered with little regard for cultural incompatibilities, supported with food and clothing but little cash and pretty much left to wander around and admire our wealth. Yepp, that's asking for trouble. The question at hand, what to do with "those people", polarizes all across the west. Surprisingly, with the fiercest reactions from those countries, accepting the least refugees in. When you look at the UK, you'll find negligible numbers of recent refugees, but a large muslim population as a heritage from their colonial ties to Pakistan, often living on the island for generations. Either way, treat'em as second class citizens long enough and some of them will likely start to become trouble. Bomb the countries or religious brothers they feel connected to and you may be breeding militants in your backyard. And if there wasn't a religious book justifying massacre readily at hand, somebody would write one (Germany, remember? Been there, done that). You guess, what I'm heading to: strengthening borders will lead to fenced in ghettos and I strongly refuse to accept that as progress in civilization. 80 million Germans can afford to integrate 1 million refugees. And the UK has to find its ways to come to terms with all communities inside its population. @Hunka Hunka Burning Love: for all I know, French police is armed. Your turn

    i have taken a short ride on the 14d and owned a 14c (for about a year) before. the difference is like night and day....the 14d pedal responsiveness is as hard as steel and its agility/answering on feet movements is really fantastic. its from all 14inch wheels the best i have riden, that have been Mcm2s, Mcm3, Mcm4 HS, Ks14c, ks14d and a generic clone the quality of the included trolley is better than on the Ks16 as the grip itself is metal also. the Leds are brighter and that was also first time i got into the new KS pedals with rubber and grip type thing, having a more V positioning a bit also. This thing is a hit for a 14inch wheel, and as it now should also come with higher possible batterie configs (14s with 680 or 840wh) is from my view the best 14inch wheel. Naming is a bit missunderstanding as the 14d for me is allready a "S" version, from drive feeling/firmware. i can and do criticize Kingsong the whole day long for some of there decisions on the 16. Even more critics on the 18 inch wheel or for general business decisions...but here this 14inch thingie is a winner! if you want something special to know...i will try to answer :-)

    @RooMiniPro, so to answer your question, which I must confess I am disinclined to do after your unnecessary rudeness. These motors are brushless outrunners, the controller has to know exactly where the magnets are at any given time so as to energise the correct coil at the right time. I.e. The RPM the motor is doing is inherently known to the controller in order for it to be able to control it. Hall effect transistors mounted close to the magnets are used to detect that magnet position. Muck about with any of that physical circuitry and the motor ain't gonna run properly, are probably at all. Of course there are two easy ways to get it to go faster: Put bigger wheels on it - that will make it faster with the same RPM. Hack the software to increase the RPM parameter.

    Actually the real police in France is called "gendarmerie" Edit: or "police nationale"... ..the municipal police the artical is talking about is a kind of regulatory person/officey.....so this municipal are no real policemen....and the gendarmerie Edit: and "police nationale".... is definitely armed!
