  2. Thanks for the heads up, so it needs to be the 7205 to charge the KS 16X (20S = 84V battery pack). Edited my post above.
  3. On a quick glance at the Cycle Satiator page, it says: The wheel battery only has DC plus and "minus" (ground), there's no temperature sensing, so just solder the + and ground. Take care to check that the polarity is the right way around. Double check that, I don't have a wheel with the Lenovo-plug, but just because Lenovo has decided that one part of the connector is "-" and one part is "+" doesn't mean other manufacturers using the plug actually follow their scheme (although probably they do). Someone with knowledge of the wheel Lenovo-connector polarity can probably confirm it (like @Seba perhaps?). EDIT: After @z3n's clarification about the Cycle Satiator maximum voltages below, do check that your model is the 7205. The other models can't reach high enough voltage (84V / 20S battery packs) to charge your wheel.
  4. This thread is now outdated and unpinned, see here for new lists:
  5. Split the lists into multiple posts to ease maintenance and removed a lot of dead links. Some might have been 404's or 500's or outdated certs, with a list of hundreds of non-working links I didn't go through them that closely... if your shop was removed accidentally, post here or send me a personal message and we'll get it sorted.

  9. Country list (NOTE: This is split into multiple posts to keep things working better, the countries are in alphabetic order) This is an alphabetical list by country with resellers who are located/ship from that country and which brand(s) they sell (at the time of adding to the list, as always, the information may not be up to date). Note that while city may be listed, the reseller may not have a physical shop there or their unicycles might be available for online-orders only and/or they might ship from a different country or city than stated. At least most sites/shops/resellers/distributors/callthemwhatyouwill probably ship to anywhere in the world, the per-country listing is to help people who want to order domestically or find out about possible physical shops near by to visit.

  11. Late 2019 version, the old thread with all the lists in first post became impossible to maintain, as the forum backend would timeout trying to update it. As there have been numerous questions about where to buy electric unicycles in country X, or which shops sell some specific brand/model, I've tried to compile a list of resellers and such to help you. It's by no means anywhere near complete, as there probably are a large number of resellers/agents/manufactures/etc who are hard to find by search engines alone, or don't have their own websites, but at least it should give you a few options where to look for. The original list was painstakingly compiled by me, using nothing but what I found here in the forums, and search engines and translation tools, and probably I can't even find most non-english sites, as I don't know the correct search words or understand the language... Hopefully you, other people and the resellers themselves will chime in to make the list more complete over time. Disclaimer While it should be common sense, let's go over a few things: This list is not a complete set of all the manufacturers/resellers/agents/etc. worldwide, and can contain errors, omissions, out-of-date information etc. While I try to avoid any errors or misinterpretations, I do not guarantee that the information here is correct in any way or at any time. I am not affiliated with or compensated by any reseller, EUC manufacturer or such in the list, nor compensated by electricunicycle.org for any volunteer work I do here as a moderator. I take absolutely no responsibility of any errors or omissions in the list or other information in this thread, or anything that may follow from viewing, using or misusing the list or this thread, visiting the sites or contacting the entities mentioned in this list, including but not limited to: any problems with the resellers, warranty issues, shipping problems or scams; loss of money, profit, time, life, limbs or organs, virginity, faith or any other damage, liability or loss you may suffer or unwanted side-effect or end result when engaging directly or indirectly in any way with any reseller, agent, manufacturer or other entity mentioned in the list. You do so at your own responsibility. While I at the minimum try to check that the site at least looks legit, I give you no guarantees of anything, as I have nothing to do with these resellers/web-sites/entities other than listing them (well, I might buy a wheel or some accessories from some of them, but it doesn't affect this listing). Basically, if something goes wrong, don't come crying to me. The list is here to maybe help you find a suitable place to get an EUC, but as it is probably never complete or up-to-date, there may or may not be more suitable options in your case elsewhere. Use the search engines, Luke. I reserve the right to remove any single entity mentioned in the list and not re-add them in case there's strong evidence that points that the reseller/entity is not legit, is dealing with illegal items or is a fraud, or for any other reason I see as a reason for removing the said entity from this list, and reserve the right to change this disclaimer and any contents of this post/thread at any time without warning. While I have expressed my opinions on some manufacturers, wheel models and such in other topics, and reserve the right to do so also in the future outside this listing/thread, I DO NOT endorse, advocate, give better or poorer visibility to, or otherwise recommend or shun any single reseller or brand over another within this listing or thread, whether I've used certain brand/model or not, or whether I've bought something from a listed reseller or not, or recommend ordering anything either from abroad or domestically or otherwise, nor breaking any international or local laws regarding importing wheels or related parts or accessories, using the wheels or in any other way. The choice is entirely yours. To put it simply, I hope this list and other information in this post is correct and useful to you, but on the other hand won't take any responsibility about anything Phew, I hope I made myself clear. Is your shop or a shop you know missing from the list, or contains wrong information? Are you reseller whose information is missing/wrong in the list? Please post to this thread, and I'll add/fix it to the list as soon as possible. Please give a link to the shops' front page or a section which shows the wheels (URL), mention the country or countries (and city or cities, especially if you have physical shop or are able to showcase the wheels in person) where the shop is located/shipping from and the brand(s) being sold. Do not advertise your shop/wheels with extraneous comments like "We have the best wheels/offers/accessories" or "Our wheel is the best and latest technology", stick to the needed information only and create a separate topic under Advertisements & Promotions for your wheel/shop/whatever, if you want to. Only resellers who sell directly to individuals (eg. private persons) one piece at a time are accepted. No whole/bulk-sales only, although it is ok if you sell both in bulk and one piece at a time. Ordering from Ebay / Amazon / Banggood / DXGate / Alibaba / other large e-commerce site (or whatever they're called) You can probably find lots of bigger and smaller resellers and manufacturers and (pretty much) any brand selling through these sites. I do not list such links here, visit the site and do your own searches to find what you're looking for. Ordering directly from manufacturer At least most manufacturers seem to sell also directly to consumers, so you can (usually) order directly from them. I have not included the contact information of the manufacturers here, but you can probably find it in their webpages, if you have a specific brand in mind and want to be sure to get the latest model. However, I have added direct manufacturer representatives who are registered in these forums, you can (probably) contact them directly with a private message to ask about the wheels/make an order. Ordering abroad vs. domestically Basically, the difference between buying from a domestic reseller or abroad is that you may need to pay additional customs duties and/or taxes when ordering abroad, depending where you are and where you are ordering from, and on the other hand, pay (maybe) more when ordering from a domestic reseller (as they've already paid the customs duties importing the wheels, and add taxes + margin on the price), but (probably) get faster turnaround and less shipping costs and such for any maintenance or warranty issues. Or not, this may vary from reseller to reseller and country to country. Compare the prices, costs and services yourself. To get more information about any taxes, customs duties or such when ordering abroad, check your local government, customs or such web pages for details and rates (and possible import limitations, if such exist anywhere for EUCs?). Warranty shipping especially overseas may also be costly, should such need arise, and if you have to pay for it yourself. Some manufacturers/resellers apparently have just sent the spare parts directly, without needing to ship the entire wheel or even parts back for warranty. Some may require the parts or the entire wheel to be shipped back. There may be costs to you or not, and they may vary a lot. I don't know, ask them what their policy is. There's also probably variation in warranties, defect liabilities, consumer protection etc. between countries, and those may or may not depend on where you have ordered the item and where you live. I suggest you find out such things before ordering. When ordering from anywhere, please note also that any transaction- and shipping-costs and such may or may not be included in the price. Locations the shops ship from Although a shop/site/whatever may be listed under country X/city Y (I've usually only extracted the location information from the "contact"-information or "about us"-section in the sites, if such is available and tells their location), it is possible that they only have an office or such in said country/city, and ship through a warehouse or other location in a different city/country. I leave it up to you to find out any issues this might affect (warranty, shipping, import duties, taxes...) before making any orders. If unsure about anything, contact the reseller/manufacturer/local goverment/customs/whatever seems suitable in the case directly and ask them. If you have any suspicions about any entity, the simplest solution is to not order from them.
  12. I guess it's a cultural thing, there is no tipping-culture in Finland, in restaurants you pay what it says on the menu, and that's it. Waitresses don't expect to be tipped, but I guess some people might still tip them every now and then, vast majority won't, and it's considered totally normal. Nobody will spit in your food because you didn't tip (but I guess they might if you're an asshole otherwise )... Nowadays since most people pay everything with plastic, it would be even more "difficult", as instead of giving cash you'd need to tell beforehand that you want to tip them so they can add it to the bill. DipJar was created originally for tipping with cards, but nowadays it looks like they've expanded to (or found better market in) fundraising: https://www.dipjar.com/
  13. Maintaining the list has become harder and harder over time, for a pretty stupid reason: the forum backend times out when doing edits to a large post, like the first one with the list of resellers: CloudFront attempted to establish a connection with the origin, but either the attempt failed or the origin closed the connection. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner.If you provide content to customers through CloudFront, you can find steps to troubleshoot and help prevent this error by reviewing the CloudFront documentation. It usually times out almost every time that I edit it, but after a few tries the changes still show up (despite timeout ). "Some day" I'll take the time to make a new post with the list split into multiple posts to get rid of this...
  14. At least the old King Song "green app" would say "Keep cycling for XX km" to show how many kilometers the battery should still last with current charge. It was just an estimation and not really accurate, but it might be what you're seeing:
  15. Even if they have 100+ previous configurations/firmware modifications, that's not a reason not to make the firmware OTA-upgradeable for the future models. The old ones wouldn't support the upgrade anyway. Saying that they "can't do this because there's so many revisions out there" is a moot point, basically they're just saying that they don't want to manage and track their production at the level required. I write vehicular ECU-bootloaders nowadays for living, it's not really super complicated to do. What is complicated, is the "tracking" of a vehicle life-cycle, with all the "birth certificates" (what ECUs / other hardware components & revisions / firmwares etc the vehicle contains at manufacturing date) and maintenance / repair tracking (firmware updates, replaced components etc). It certainly adds up to the time and cost of production & maintenance. "Some modern motor vehicles have up to 80 ECUs. Embedded software in ECUs continues to increase in line count, complexity, and sophistication.[2] Managing the increasing complexity and number of ECUs in a vehicle has become a key challenge for original equipment manufacturers (OEMs)." https://en.wikipedia.org/wiki/Electronic_control_unit But wheels have only one MCU (MicroController Unit, I guess if stretching the definitions, the entire mainboard could be called an "ECU") running a single piece of firmware. It should be much, much simpler, if they just keep good track of what board revisions, peripheral devices (BT-audio, lights etc), motor and firmware revisions are there in model XYZ, along with proper version "stamping" (hardware and software) so that the bootloader knows to reject incompatible firmware as a failsafe, and can tell the "programming device" (ie. an app in a mobile phone for wheels) the hardware & software configuration of the wheel, so that the app knows to fetch the compatible firmware version. It's not even complicated to make it possible to update the bootloader itself (which is actually required in ECUs) through the same software and communication method which is used for updating the firmware itself, ie. without any special-purpose programming device that would need to be shipped back and forth between reseller and manufacturer, or separately purchased by the reseller. Whether it happens over-the-air with Bluetooth or over CAN-bus, doesn't really make much of a difference from the the functional standpoint.
  16. Check that your multimeter probes are connected correctly (current vs. voltage measurement) before measuring. The power spike before the BMS cuts the power / meter fuse blows is enough to vaporize your probes if you plug them in the battery connector with the meter set up for current measuring... guess how I know? Acetone can be used to "weld" plastic, it liquifies the plastic, which then hardens again once the acetone evaporates. Use small amounts at a time and be careful, the plastic starts to melt pretty quickly. Also inhaling the fumes a lot isn't exactly healthy, so good ventilation isn't a bad idea. Never had more than a slight headache though Mixing plastic (such as Lego-blocks, which are ABS, or something like 3d-printer filaments probably would work nicely too) with acetone creates a "slurry" which can be used to fill in small holes or cracks, or create new threads for screws in plastic (fill the hole to re-thread with the slurry, insert the screw, maybe move it a little bit up and down to ensure the liquid plastic settles in the threads and leave it there until the acetone has evaporated and the plastic has hardened). Easiest way to make small amounts is to take a small glass jar (preferably with a lid), pour some acetone in there and drop the blocks or 3d-printer filament or whatever there, close the lid and swish it around for some time until it has even consistency (the time it takes depends on plastic, sizes of blocks, amount and purity of acetone... if you just leave it sitting it will take a long time, but twirling it around makes it much faster). More acetone vs. plastic makes it more runny and vice versa. Somebody with more understanding of chemistry once said that using solvent-based "gluing" is far superior to "normal" glues, because the bonds occur at molecular levels, ie. basically the parts melt together instead of being held together by a layer of other substance. Draining the caps is a good idea before touching anything on the mainboard, probably pressing the power button is enough, or just place a small resistor across the cap legs and wait a bit (careful not to short anything else with the resistor legs!). But when plugging back in, the discharged caps will pull a high current spike when they recharge and can cause sparking, people have destroyed the connectors this way and in at least one case, the MCU fried (Rehab1's ACM). Either use a XT-90 with "spark arrestor" or use small resistors (if you don't know what I mean or how, then don't try it, I don't have the time to draw a diagram right now ) between the battery and mainboard connectors first to recharge the caps, then connect normally.
  17. The ubiquitous term used most commonly has been "wheel" ("wheels" for plural) for years now.
  18. I don't actually check the voltages themselves, but over the last winters, I've stored the wheels discharged to something like 30-40% for 6-7 months at a time, and they've never discharged enough to even drop much, ie. looking at the LEDs showing the charge, I've had 3-4 LEDs on out of 9 on both KS16's when putting them to storage and still had 3 LEDs on in the spring. All batteries were left connected to the wheels, since KS's don't draw power from them when off (most wheels don't, with the exception of Ninebot Z-series which have relatively huge vampire drain that sucks full batteries to empty in about a month or so, those things need to be charged often during storage, or preferably, disconnected from the wheel mainboard!). For other than Ninebot Z's, likely the only thing using power when the wheel is off is the BMS, and the current it draws seems to be somewhere in the microampere-range, and then it won't matter if the packs are connected to the wheel or not. Four 16S1P -packs each with their own BMSs I've stored in a ground basement under the house, that has temperatures ranging from freezing to maybe 15-20C, have been there for about 2-3 years without charging in-between, when I checked this spring, they were around 56V (I think I charged them to around 57-57.5V when I put them there).
  19. The ACS712 is a current sensor microchip using the hall-effect (magnetic field caused by flowing current) to measure the amount of current and output it as an analog voltage signal. https://www.allegromicro.com/~/media/Files/Datasheets/ACS712-Datasheet.ashx My best guess would be that the controller might go into some sort of overvoltage lockout if the motor isn't turning and it senses too high voltage (48V controller sounds like it's meant for something like 11S or 13S batteries). Have you tried discharging the batteries to a lower voltage to see if it then starts running? Then again, if it starts running without load (if you mean you turned the bike upside down by "backwards"), it might be related to the ACS712 (controller detects overcurrent when the motor's still stalled at start-up), in which case maybe a small voltage divider to drop the detected current value might work? EDIT: No, it won't work, the sensor's bidirectional, so it would move the offset away from the "zero current" -point at half the supply voltage, it would need a more complex set up with an op-amp or such... But I'm really just guessing... Either way, perhaps it would be best to get a controller that has suitable maximum voltage for the batteries? A better place to ask might be something like the Endless Sphere (e-bike) forums: https://endless-sphere.com/forums/
  20. Yeah, time has flown pretty fast looking back. I removed the foam after the first summer, no video though Not that there'd be much to see, I purposefully used a crappy 2-sided tape (not the 3M-stuff) that was easy to peel off and left without leaving marks. If it would have left residue, I'd have just cleaned it off with IPA anyway... But here it is in its original beauty: <3
  21. Yeah, the funny thing is that the price has stayed pretty much the same since the release. Guess there's enough demand for them still that there's no need to drop the price. I've been happy with mine, zero issues after 3 summers and while I haven't measured the actual battery capacity since the first summer, I haven't noticed a drop in the capacity so far (although likely after that long there is some).
  22. I guess they're pretty random. But you could try mailing them directly and ask. The owner seems like a nice guy.
  23. Yeah, the sale price is only for the 420Wh version. Check out other possible options here:
