    Wee J @ his school talent show, they were a bit short on space. We played a video in the back ground as he wasn't able to fit a flying trapeze or aerial silks in his school. LOL

    I designed a motor that has been patented in China, which will change the design of EUC.

    Okay, this may be just another crazy idea but hey, I figured I would throw it out there. There is a bike trail from Washington DC to Pittsburgh PA called the Great Allegheny Passage that seems like it would be a fun trip: https://gaptrail.org/ I checked and their official policy allows EUCs. If they don't check the rating on the motor you could even ride a Gotway Monster! "Bicycles with an Electric Assist System are considered to be any unicycle, bicycle, tricycle, or quadracycle with an electric motor not exceeding 750 watts of power, a maximum weight of 100 pounds, pedal-assist, and top-speed utilized not in excess of 15 miles per hour, or less if otherwise noted.* *This definition is in compliance with the Consumer Product Safety Commission Public Law 107–319, 116 Stat., Act 2776 and the Federal Highway Administration Title 23, United States Code 217." Just to give you an idea of pace and time, take a look at some of the organized tour sites. They have people covering about 50 miles a day which should be easily doable for most EUCs and leave some time for off-trail exploration. The entire trip takes 6 days. https://wilderness-voyageurs.com/adventures/pittsburgh-to-dc-gap-and-co-bike-tour/ Pittsburgh area also has the steepest street in the United States if you want to test your EUC. https://en.wikipedia.org/wiki/Canton_Avenue I am completely out of vacation this year but would really love to do this some day.

    I must respectfully disagree to set at least the record straight concerning my beloved KS14C and to inform others. I did not jump curbs, no drops taken, and am not heavy at 75 kilos and my axle went bad anyway! And also did not ever get over the hip pain hurting stage to ride one foot, still not, so this might have also added stress even for super short periods of time, but it sure seems ANY EUC should be able to handle one foot riding for extended periods of time! I just advise all those with maybe even ANY E U C, but for sure any KS14C, to check the spacing between the pedal supports "pillars"? and the wheel, motor sides. AND STOP RIDING IF YOU HEAR ANY SCRAPING SOUND AND CHECK AS SAID ABOVE! It also could be very well true that some axles are and will remain just fine, while others fail. I am VERY interested to see how my warranty replacement axle holds up? ukj

    12 inch, power 1200W, very suitable for mountain off-road EUC. Also use the 247 package MOS, the controller will be installed in the middle of the motor.

    Considering that the axle needs to be hollowed out to have wiring come out of one side plus it requires a flat side or two, wouldn't it make life a lot better to just have a larger bearing and axle diameter? That way you can pass through heavier gauge wiring easier, flatten sides all you want and eliminate the possibility of axle breakage completely? Sure the motor covers would need to be able to accommodate the larger bearings and thicker axles would be needed, but in the end a little over-engineering can avoid problems from ever occurring. If an axle breaks once, it likely will happen again. Why not eliminate that possibility with some simple changes? How much can a slightly larger bearing and axle cost in the large scheme of things? If you ask someone do you mind paying a little extra for an axle that can never break, or do you want a wheel with an axle that might not break if you're lucky, which one do you think they would opt for after riding somewhere for 30 kms in the middle of nowhere?

    I walk the wheel down, no exceptions. However, I have occasionally dropped off a sidewalk by accident on my V5F, once was a huge drop (to me) and...nothing. The wheel did not skip, there was no loud noise, there was no heavy impact, nor loss of balance. It's as if you'd be better off just pretending the drop doesn't exist. I've fallen many times by slowing quickly and bailing when my wheel gets stuck. Saying that, I absolutely do not drop down any curb. Well, if it's an inch high, and even then I do not do that on my KS14C. Now going up small curbs using a little hop, that's a lot of fun and I do that a lot. Approach the curb (maybe 3 inches max), cruising slowly, bent forward with bent knees, and right when the front tire catches the lip of the curb jump up! I don't squeeze the wheel at all but rather just let it crawl awesomely up and over the curb. Occasionally I make a perfect leap but much more often I'm a bit (or a lot) of balance. Great fun! You'd be surprised at how much fear is involved in jumping up a tiny curb like that which, realistically, you'd have to be a total dork to injure yourself, but I assure you I chicken out plenty of times when approaching a curb to jump. Some of those curbs look like this to me...

    Ohhh, wonderful! It works! Shipping such appliances to the world is part of the "German Initiative for Global Garage Learning Experience (GIGGLE)"! You know, "Give a man a fish..."

    I would feel very disappointed with a machine that failed so catastrophically within a couple of thousand miles.

    The Amish are so gracious! Normally they do not like their photos taken but the father agreed...sort of. Interesting contrast in technology.

    KS changed that with two caps on later versions...my 14 c had this second cap on the same place where you put it, so i guess that is ok.... secure it by some rubber pieces, so that it can not move or brake his legs! to the usb: older versions of this small board had usb...but it was getting rid of because its in no way waterproof! So IF you want use it ME PERSONAL would take a extension cable to make it longer and lead it somewhere out, where water can not go in the shell..... dont use it by pulling a hole into the shell on the upside or if you decide to do that, then do silicon it like hell and use a waterproof plug to secure it properly!

    Here's a cherry I've popped way too many times. My frickin' Bosch piece of crap dishwasher!!! It seemed like such a good deal a few years ago, but gosh darn it German engineering is not so good. I have had to fix it countless of times. So many that I know every component by heart! It leaks (fixed), the soap door doesn't open (fixed), water doesn't drain (fixed), stops prematurely (fixed) and now it quit washing. This is the water pump. It's not really designed to be opened up easily, but I did it anyways. That grey thing is the impeller which has these tiny plastic legs that apparently clip into the thin fibreglassy nipple spinny swiss cheesy thingy to drive water through the spray arms. Notice all the tiny legs have busted off. Why not just make a simple metal propeller pump that would last forever? Nope that would make too much sense. So basically I JB Kwikwelded the impeller back on praying it will stick for a little while until I get a replacement pump. They also use these stupid plastic clips that are impossible to reassemble as you have to press fit the shell back together. Ugh why not just incorporate four bolts with nuts to fasten it all together? That would be too easy. Luckily I managed to reassemble things, and it all works again! Yippee! When it works, it works pretty good, but when it dies it is a pain to fix all the time. I'm glad that I can do it myself rather than call the repair guy in. I have to add appliance repairman to my signature... Bosch. Is that German for "Busted?"

    Have you ever considered axial flux motors? Custom design can be made much cheaper than radial flux motor because stator design does not require custom laminations to be stamped .

    Those are the two electrolytic capacitors. Be careful with them as you don't want to short or damage the metal legs. Is that one cap off board? Wow looks like someone soldered some wires to the cap legs to allow it to be stuffed in the side area because it's too tight around the board? That's interesting and not really a sound kind of design element? It should work, but I would secure that cap with some tape to the casing or something to avoid it bouncing around due to vibration. Are you sure you got the right parts version for your wheel? Regarding the USB there are USB extension ribbon cables you can get, but maybe a correct part would be better? Did your old board have an extension cable?

    I have done over 1000km on my E+ running 1.4. I have not had any problems. I have run my battery down so low that the max speed is a brisk walk. It has never cut out. When you say that most people have little faith in Ninebot what are you basing this on? I thought Ninebot machines were generally considered to be quite reliable, well built and safe, albeit somewhat slow and boring by current standards.

    Yesterday was the most visited for this site ever just a year ago. I don't know why and am hoping someone else does. Also, where was the party at? When do we declare a dedicated day to the art and hobby that is EUC-ing? What day? Do we just toss a dart at the calendar? Who tosses the dart? Do we toss a dart at the member list? Plz Help.

    I saw a second cap on a video about changing a tire on a KS14C. I was wondering why that wheel had two caps instead of one. I considered adding a second to mine when I was replacing the control board, but it was a real chore just getting the connectors tucked in beside/under the battery, let alone another cap. So, I didn't bother. Anyone want to speculate why KS seems to have doubled the amount of capacitance at some point?

    Maybe they have price breaks for larger quantities, if you made a group order then the price could get lower per pair? Of course better make sure the measurements and design is correct before ordering a big bunch...

    These are the ones I used - By having them on the inside of the leg they provided support and padding so that when gripping the EUC (as most do when learning) the pressure was spread across the guards and not on one area of the leg/shin. As I said - without these I was in too much pain to ride the EUC as the pressure was on the damaged/painful area.

    I can only speak for the Rockwheel GT16, and it reacts instantly at 20mph and I weigh in at approx 204 lbs. I can't attest for speeds higher than that, as I avoid going faster for very long...

    @Spark: Great suggestion - I'll make sure we include that when we hopefully get far enough with this to collect a list of design principles! I really like the fact, that it promises more accurate warnings while being pretty easy to implement. What could be a bit more challenging is making it safe for the casual change of riders (you know, that "wanna try mine"-situation at group rides). One idea to solve that: store individual settings on an RFID chip for example in an ankle strap. That could also solve the issue, that any "beginners speed restrictions" for the first 100 km or custom settings to turn off alarm and tilt back should really be dependent on the rider, not the wheel. Letting a beginner ride such an "unlocked" beast, is a bad idea. So, the wheel defaults to the safes possible setting. Only the presence of the RFID switches to the customized settings, incl. riders weight. Geez, now you got me to troll my own thread off topic ....

    Seems to be a shop in Taiwan, neat. People seem nice. I love how the shell is not mirrored, but also flipped, so you only have one shell part that fits both sides. Power button on the one hole, charge port on the diagonal hole, cool. It's just quite neatly constructed.

    Thanks @Carlos E Rodriguez! While we are on the same subject, we are closing in from two different angles: You are talking "fire fighting", I am talking "fire prevention". Bear with me, please, I am little of a technical expert, but a consultant at heart: I have seen time and again, how businesses fail by just reacting to problems at hand, but neglect to develop a systematical approach to prevent such problems to occur in the first place. It's part of the growing pains of small enterprises, I guess. Investing in quality often seems like a luxurious waste of money initially. Why hire a completely unproductive "Quality Engineer", when you don't have enough people to assemble desperately awaited orders? That's where I believe we must step in: Regardless, of what design principles we prefer (enforced safety limits vs. choice to deactivate the safeguards), none of us wants to faceplant, because of crappy parts inside our wheels or stupid, undiscovered mistakes during montage. Here, we all agree! So, it's up to us to let the manufacturers know, that we expect 2018 EUCs not only to be "faster, higher, wider", but positively more reliable. Every. Single. One. Next year, I want to unpack and test ride my new wheel with sweaty palms from pure excitement - not the sweat of fear, my new pal may fail me miserably. And I beg all of you, to help making that happen.
