  1. I recently sent my two CLG-150 chargers to a friend who is using one of my bikes as a test to see if she likes ebike commuting. So I needed another charger and scored a near-pristine HLG-320H-54A on Fleabay for $50 delivered. Its near-pristine because it was missing the rubber pot plugs. I found these as replacements. They are stiff but you can use your little Phillips adjusting screwdriver as a mini prybar and stuff them in the hole with it. Then use the tip of your rotating thumb pressing down to 'screw' them in fully. They end up being such a solid, snug fit (still easy to pry back off) I would be comfortable giving them a blast of pressurized water at the local jet wash. I won't... but I could I think. https://www.amazon.com/dp/B07LGNZXLG/ref=cm_sw_em_r_mt_dp_U_O6FVCbDMKVP9R
  2. @BillieC it works both ways. I got into this in more detail in the installation/assembly posts at the beginning of the thread, but to revisit: You want to power this thing up before connecting to the battery (thereby giving it a 'soft start' so there can never be a spark upon connection). When the unconnected charger powers up, you are seeing the source readings. You will see voltage and this is the time you adjust the final output voltage you want to reach when the battery is fully charged. As you can expect, this is usually a set-it-and-forget-it job but if you are smart and doing balance-charging, you can set it for 80% and then one day decide you want 100% for your balance charge. Once you connect to the battery, the readings you are seeing are now a mix. The amp reading is the current level being fed in real time. The watt reading is the wattage output on the charger. The volts are now the volts on the battery rather than the target charger voltage (and under charger load, the battery voltage reading will be higher than it will be when you disconnect unless you complete the charge cycle). The amp-hour reading is a cumulative measure of what you have fed into the battery since power-up and personally I pay no attention to that. Also, if you have no connection to mains power (for example the cutoff timer you should be using expires and shuts the power down) then the meter will read only the battery voltage, with zero watts and amps.
  3. For anyone else who comes by and sees this thread... The aftermarket vendor who sells the 100mm x 177mm bottom brackets that work for the Originals now makes an 80x142 bottom bracket that matches the spec of the Sondors Thin. At least on paper. It will take a few weeks for someone to buy one and for it to get here on the boat so it can be measured/installed/etc. I found it by searching on '80x142 bottom bracket' in case this links stops working: https://www.aliexpress.com/item/ZTTO-Bicycle-80mm-100mm-Square-Tapered-Bottom-Bracket-BSA-80x142-100x155-100x177-80-100-Axis-For/32965224214.html?spm=2114.search0604.3.2.24bf6f36lH7zD7&ws_ab_test=searchweb0_0,searchweb201602_3_10065_10130_10068_10890_10547_319_10546_317_10548_10545_10696_453_10084_454_10083_10618_10307_537_536_10902_10059_10884_10887_321_322_10103,searchweb201603_56,ppcSwitch_0&algo_expid=011a95db-d8e8-40fd-9316-b30d577c856e-0&algo_pvid=011a95db-d8e8-40fd-9316-b30d577c856e&transAbTest=ae803_3 There are presently three separate sales listings for these. Note that the Sondors oem replacement for the 100*177 Original is sold in the same listing.
  4. @BrokenBearingsJosh You need to go to the Sondors Storm Owners Group on Facebook. Once there ask to join (I'm one of several group moderators and we approve new members quickly) Once inside, there is a link to a support form that you can use to get to Sondors tech support. Not sure why you haven't been able to get a direct response as I also know Sondors has a supply of Thin bottom brackets held in the warehouse specifically to deal with situations like yours. While in the Group, I suggest opening up a thread and asking the community for help on this as well. That will trigger folks' to tag the Sondors support reps who frequent that group and who are tasked with fast-tracking help in situations like yours - assuming they do not see your post themselves and contact you directly. Don't worry you'll get it fixed. edit: And yes... that bottom bracket/spindle combo is a unicorn. I know an aftermarket source for the Original/fatty bottom brackets, but there's nothing on the open market for the Thins.
  5. Just the standard lever. No need to mess with anything that also mounts stuff like shifters. I had a set of MT5e's that were take-offs that had the shifter mounts and if you get them, they will still work. Just will have a fitting on them you won't need. The picture in the first post shows the std lever.
  6. By the way, at $120.79 this is currently the best online price on MT5e's from this vendor, 365 Cycles: https://ebay.us/IB6q2H I have bought - I think - three sets of these to date *from this vendor* for various bikes I have built (add a couple more sets from bike-discount.de and the German bike shop guy... Karl Vom Kanal, if I remember coorectly. So I have a bunch of them and essentially have standardized on one brakeset and one rotor size (205mm) so I only have to stock one set of spare parts across what is now a small fleet. Interestingly, that first set on my Sondors sprung a leak on the front caliper. So I backtracked my purchase date and found a) I was within Magura's warranty and b) 365 Cycles was a certified Magura dealer. So warranty claims honored. I contacted them, they contacted Magura, I documented the problem to Magura's satisfaction and Magura sent me a replacement caliper, set of pads and even a rotor. I did point out that a) the pads while contaminated were worn out anyway and b) the rotor was just below its 1.80 mm wear point, so Magura need just replace the caliper. They very nicely sent me the works anyway. FYI I did go to a fair bit of trouble to try and save the pads via the 90%+ alcohol and blowtorch method, and also worked hard to clean the rotor - all during the diagnosis phase of the problem. My conclusion... don't waste your time. Just buy new pads and spend the time you saved out riding. Speaking of pads, Magura Type 8.P pads - the best for the MT5e - are quite pricey from USA sellers. But Rose Bikes in Germany has them quite cheap. As I mentioned, I have a small fleet of ebikes now and one set of common brake parts. So I stocked up on 4 sets of pads for about $17.50 a set. https://www.rosebikes.co.uk/magura-8p-performance-disc-pads-for-mt5mt7-2652120 thats the place to go for pads.
  7. Hi sorry I missed this. You want the NO (Normally Open). AKA "Closer" version. In German: "Schliesser"
  8. "domestic brand" = Chinese no-name. If that weren't so they would say the battery make (Samsung, Panasonic, LG etc.) immediately and out loud. They would also specify the cell type. A 2600mah battery is solidly mundane in its capacity. 18650 cells charge to a range of 3.0v (0% and a forever dead battery at that level) to 4.2v so the 3.7v number is meaningless... its just the 'nominal' number more or less universal to all such cells. When you connect two batteries together like this, its called "parallel'ing" them and there are risks to this. You can overcome many of them by using identical packs of identical cycle counts, with 0 cycles being preferable. Charging separately is the commonly accepted safe way to charge them - disconnecting the batteries from one another - but this is a pain and reintroduces the risks inherent in making the connection back together again. I would google that subject to learn more. There are advantages to parallel'd batteries. The output capacity is doubled. So likely your 30 amp shark packs are now capable of 60 amp draws. Also obviously the overall amp hours (the size of the gas tank) doubles. Long term, if there are failures or degradations in the cells, or the BMS of one starts behaving a bit differently than the other one, you could introduce problems. With potentially catastrophic consequences. Only potentially but the risk exists where using a proper single pack would not have them. Having the packs parallel'd do not give you some of the benefits of a single pack. For instance you cannot do the high charge rate you could get away with on a 13S8P pack... you are still charging with a 13S4P pack that bleeds charge over to another one. And you are charging the second battery thru the discharge port, which will bypass some protections against overcharging (and exploding) on most BMS'. If you are smart you will charge slow and use a mechanical cutoff timer is a mission critical safeguard (if instead you are separating and charging you have the instant-equalization risks that go with connecting the two back together again so arguably not a step up). I've been using a parallel'd pair of Luna Mini Cubes to make a 12ah battery out of two 6's for a couple of years, as part of a 2wd twin-motor, twin battery setup. I haven't had problems but for safety's sake I am switching to a custom built, single pack with a high-discharge BMS. Its not cheap but its the smart thing to do. Your guys are getting the job done via a shortcut.
  9. Yes this is an EU- mandated surcharge on the bikes. Sondors is as much a victim as the consumer is. If you followed the EU bike tariff complaint filed by the EBMA, it really was ... well, disgusting. Protectionism at its very worst. EBMA cited a Stromer as a properly priced ebike and Chinese bikes as therefore 'dumped'. I am oversimplifying greatly but that is what it boiled down to. Take that EU consumers. Bafang is reportedly scouting a manufacturing plant in Eastern Europe. Its within the EU but not subject to Swiss wage levels. They will wind up being just as competitive as they are now but the tariffs have held them off for a couple of years putting this into place. I have heard of other parts mfrs moving to Other Asian countries like Taiwan and Vietnam which are not subject to the dumping tariffs.
  10. None of your links work. Looking at their site, looks like their 'quads' are Surrey bikes, with one neat-looking 4wd fat tire quad (as in four powered wheels) for a princely sum. I'd hope very much they have perfected their driveshaft system to run with decent power. The motor they show in the pictures is a 3000w Cyclone and they are advertising a 500w mid drive. As for pros and cons, generally: Bigger = more range. But also more weight. For a single-person ride, even if its a quad, 40ah is colossal. And colossally heavy. 14.5ah is typical for a bike. Probably too small. Beyond that, battery choice is a complex subject. Just stating 'Panasonic cells' doesn't mean a whole lot other than they are less likely to explode or wear out quickly. But only if the builder knows what they are doing.
  11. Nothing special... Really its about your own preferences. I go for speed. My bike is geared to be able to pedal along at 32 mph and I ride at PAS5/PAS5 continuously, with C14 set to boost my PAS signal, so if I am pedaling, I accelerate harder than if I use throttle... assuming I leave C5=10/C5=10. However over time I have found that if I am running full-blast PAS at all times that acceleration with two motors so strong can be dangerous. So as much as I like to be pinned back into the seat, I have set both motors to C5=0 - the full strength slow-start. Note there are two other levels of lesser slow-start in C5=1 and C5=2. Undocumented on the KT-LCD3 but in the KT-LCD8H manual and functional on the older LCD3. Even with slow-start on both motors (and I have tried it to lesser degrees before settling on the full on slow for both) acceleration is strong. remember C5=0 leaves you with full wattage. So acceleration is still strong... Its just not sudden which I find to be a lot smarter in traffic. On the other side of the coin, Houshmand goes for range. He uses C5=4 rear and C5=3 front. Also his front motor is a 25a/48v whereas mine is 52v and 35a on both. Experiment. But I'd suggest starting slow regardless. Even the lowest power levels will feel like a lot at first.
  12. The Panasonic GA is only a good choice when you are piling it into a very large pack. While it has a relatively high data storage capacity at 3500 mah, It doesn't handle power drains well. It is rated by the manufacturer for a 10A drain, which is not particularly strong (in the battery world of, say, 2015 you had a choice between storage and power output, so the GA went the storage route). Here's where it becomes smart to use GA's in bigger packs: They are rated for 10A but they get unusually hot The DIY battery crowd's rule of thumb with them is to keep them to about 7A (remember, heat is what kills a cell). Thats pretty low, but just fine for any Sondors application you can think of; especially in a big pack like Reddy Kilowatt is describing. https://www.imrbatteries.com/sanyo-ncr18650ga-3500mah-10a-flat-top-battery/ Look at the cost per cell. Also for the era of 2015-ish, the Samsung 25R was on the other end of the storage vs. output world. This cell has a 2500mah capacity so significantly less than the GA. But it is rated for 20A output... and that output rating has turned out to be conservative. You can beat the living snot out of a 25R pack and it will take it and stay cool. Since the cells are also older tech, they are inexpensive. I use a 25R pack on my BBSHD/Bafang AWD bike to run both of my motors. It has a 70a continuous BMS which is higher than anything you will find commercially produced, and it can take that draw no problem. https://www.imrbatteries.com/samsung-25r-18650-rechargeable-battery/ Considering the power and reliability of this battery, its a good thing, right? Look at the cost per cell. The lowest of any described here. Double bonus. The tradeoff is that capacity. If you are targetting a particular capacity you will have to go to a physically bigger pack. But not colossal. I have two 25R packs, one from Luna designed for the Sondors, and another custom built - at 17.5ah and 20 ah respectively and they aren't unusually large. As for the EBW batteries that are so inexpensive, they use Panasonic NCR18650PF cells which are decent storage at 2900 mah and decent output at 10A. And they don't get hot. So... superior output to the GA in real-world, at the expense of some capacity. Look at the cell price. They aren't cheap but also not the most expensive. https://www.imrbatteries.com/panasonic-ncr18650pf-2900mah-10a-flat-top-battery/ So much for the 2015 era of batteries. What about 2019? Remember the inevitable trade-off between capacity and output? Enter the Samsung 30Q. 3000mah capacity and 15A output. Quite the nice compromise vs. a 25R's output. I have two 30Q batteries: First is a pair of 14S2P Luna Mini Cubes wired together in parallel. They get hot. Not a shock considering they are 2P packs. But here's the thing: The 30Q is made to take high heat. Thats more or less unique for an 18650. My second 30Q is a Luna Wolf pack, a 14S4P 12ah potted, crash- and heat-proof super battery, essentially. Not cheap at $600 but their BMS is underrated (its actually capable of 100a continuous and dialed back at Luna) and its been shown to run a Tangent Ascent at full chat without frying. Considering that is a motor that is commonly run at 60-80 amps - or more - thats saying a hell of a lot for a 4P pack. https://www.imrbatteries.com/samsung-30q-18650-3000mah-15a-flat-top-battery/ And look at that cell price. There is no longer a premium on them. I am presently having a battery custom built for me to fit into an XL frame's triangle. Right now I fit my Luna Storm 17.5ah 25R battery, and my two parallel'd Luna Mini Cube 6ah batteries, for a total of 29.5ah. The new battery will be all 30Q's. My current 29.5ah 'pack' weighs 19 lbs. The 30ah 30Q weighs 14 lbs. It is 14S9P so heat will be a non issue, which is a good thing because it will have a BMS rated for 80 amps continuous, with a 150 amp peak and I'll use that. Good luck matching that weight and output with ANY of the other cells listed above. If you want current best-of-breed, its the 30Q. But its by no means the only choice. As you can see from the above, there is no single best cell. You have to understand the ins and outs of the cells in the marketplace: what they are good or not so good for. Your decision needs to take into account size, heat, amp draw (always always always find out what the BMS is rated for and ignore its *peak* capacity. Make sure its *continuous* capacity exceeds your controller's *peak* number or you will trip the BMS when the controller peaks for more than the second or three. Been there done that on throttle going up a hill and the unpowered ride back to the charger to reset the BMS ... sucked). As for UPP/UnitPackPower, you see some folks over at Endless Sphere saying both good and bad things about them. The good usually comes from new purchasers happy they saved a bundle. the bad comes from folks who have been using them awhile. The unspecified-cell packs are Chinese cells - not a big shock. Look carefully at their BMS numbers. Usually they keep them pretty low, and you do not want to be running a BMS at or past its max continuous capacity to run your bike. I personally wouldn't touch them with a 10-foot pole. What is your house worth? What is your house worth after it burns down? Your battery pack business should not go to the lowest bidder.
  13. Ralf, I buy a lot of stuff from Rose Bikes. Especially my brake and drivetrain parts. I just bought four sets of brake pads for my Magura brakes and buying in that quantity offsets the shipping cost from Germany so I am still saving a lot. https://www.rosebikes.de/shimano-b01s-disc-brake-pads-701755 https://www.rosebikes.de/kool-stop-shimanotektro-disc-pads-160817 The pads are the same as Shimano pads so you actually have quite a large variety of suppliers to choose from.
  14. Along the same lines as the link above, Rad Power Bikes owner Mike Radenbaugh has acknowledged that the motor is in fact a 500w Bafang that has been re-marked as 750w because it is warrantied to perform at 750w.. Its better if I let him tell it himself: For the sake of complete context, here is the link to the original full thread https://electricbikereview.com/forum/threads/question-about-the-motors-on-the-radrover.6314/ In a closed ebike group in September of 2018 this issue blew up again in a big way. Mr. Radenbaugh essentially re-stated the above position - that the motor's designation denotes what it is warrantied to run at. I'll skip posting the screen shot but I do have the entire discussion saved as a gigantic PNG file.
  15. There should be no changes needed thanks to your controller switch. Plus you didn't change the motor... so its a direct swap. When I upgraded one of my LCD3's to an LCD8H, all I did was copy over the settings. The exception to that is the initial settings which are different. I changed Km's to mph by setting the third entry to '3' which Kyle notes in his video, linked above. the LCD3 and the LCD8h are essentially identical under the hood. The LCD8H is just easier to set up and its display shows everything you need on one screen vs. the LCD3's three screens.
  16. I had the opportunity to make another charger over the weekend for my daughter and son-in-law, who have matching Original 'X' models. They also live in the EU and as such I needed the appropriate plug - the charger will auto-sense the voltage coming in and adjust accordingly. So for those of you folks outside the U.S., here's what one looks like. My daughter's locale uses a 2-prong grounded 'Schuko' type plug which I got from a UK seller on Fleabay. One nice thing about using international parts is they conform to the same international specs. So there is none of the translation necessary to pick which wire goes to where. Just match the colors and you are done. [click on any image to embiggen in new window] This time I took the time to take pics before and after during assembly. The heat shrink and adhesive on the marine-grade splice connectors make for a very solid connection. There is a trick to doing the best crimping: do it on the very ends don't crimp so hard you tear deeply into the plastic covering the splice ensure the pointy prong on your crimper faces AWAY from the other wires so if you do overcrimp and tear into the plastic, you won't expose metal facing the other wires. Use a halfway decent crimper. I think I made this point in the original post but it bears repeating. Use the wrong tool for the job and your results will suck. There is also a trick to heating the adhesive connectors - First, use a nozzle on your heat gun that narrows the heat exhaust so you can better direct it to a small area. Next, heat the ends that you actually need to shrink up and grip the wire. Stay away from directly heating the metal center. If you do that, any tearing of the plastic over the crimp tends to actually seal itself. If you heat the center, those tears will break open further as the adhesive plastic shrinks from the heat. Its actually pretty easy to do... you just have know to do it... and now you do. Heat shrink over top of those adhesive connectors and you have a stable, solid connection you need to look for to notice. Do it again for the XT60 'universal' output connector. Make sure that external heatshrink is plenty long. In this case I made sure I had plenty of exposed wire on the end because I like the flexibility. If I wanted to reinforce it and maintain that flexibility, self-adhesive silicone tape (sticks only to itself; spiral wrap it around the wire) is the perfect solution. The Sondors-compatible bottle connector I chose for this charger had a male plug end on it, so I needed to make another connection using a short female-to-female XT60 extension. It is important to get your genders right on a charger. You do NOT want a male XT60 or male anything else exposed on the battery side as an arc between the terminals is much more likely on a male plug, and that can destroy your battery. Here's the whole thing put together with a meter added to the end and the Sondors-compatible 5.5mmx2.1mm barrel connector attached. The meter is showing it is configured for an 80% charge on a 52v battery. After I took this pic I realized I needed to set it up for a 48v battery on an Original X and changed the voltage on the charger and the label on the meter.
  17. AND it is touted as "Made in USA". Fat lot of good that did me. The problem with all of these meters is they cannot be calibrated. The Watts Up is advertised as accurate to +/- 1%, which means a 58.8v charge could be read as 59.4 (which means if it says '58.8' you didn't quite charge to 100%) or it reads 58.2... which means if you didn't calibrate it then you will keep charging past the 58.8v limit and literally burn off your potential cycle life on the battery. If one of them could just have a potentiometer like the Mean Well chargers have on them... you could dial the reading up or down a tad and problem solved. No such animal that I have seen. After I tried that meter in the post above I dug out a spare Tenergy (a.k.a. Amazon Chinese clone), put a connector on it and checked it. It was off by -0.40v. I can live with that. Easy to put a label on the meter.
  18. The advantage of using the ETRTO tire measurement system is its supposed to give you a genuinely accurate measurement on casing width. 50mm is a hair under 2". Up to you to decide if that leaves you enough room... assuming the casing width is true to size. Oftentimes they are a little optimistic (real tire is thinner) so in the end... you will either have to find someone who has fit those tires or just jump in and hope for the best.
  19. Well, I was hopeful I would have the same experience Manx Mariner did with his Watts Up meter. What I got was the worst inaccuracy I have ever seen on a meter that cost double the others I own. 55.4v of current is being read as 58.6. Its just as bad if I connect the meter directly to my battery sans charger. So... live and learn. I'm glad Manx Mariner got a good one but clearly the $30 meter is every bit as much of a crap shoot as the $15 Chinese copies.
  20. And another.... Also barely worn. I just picked the last two reports. These are typical examples. Note both tires have almost no wear. Again if you see this issue follow the instructions on the Sondors site and report the problem with pictures.
  21. One more thing, direct to @JCJ: You stated 1148 miles on the tire. Yours is the first of these failures I have seen that took so long to evidence itself. In every prior instance, it was a tire that hasn't been used much. This example is a typical one. This tire had 700 reported miles at 16 psi on it. You have less than twice that and your tire is worn completely down. Since the rubber compound on these tires is known to be pretty durable, there's something going on with your use. Its not tire pressure as 17 psi is not an issue.
  22. Sondors is now managing its warranty and tech support through the Facebook group, as you can see from their web site. As part of that, the separating tires are a known issue and there have been enough reports and photos showing the same problem to conclude there was a bad batch of tires. It is being dealt with individually. In the case of JCJ's situation, there isn't anything to warranty as he already got the full use of the tire... it is completely worn out as pictured (sure you could push it a little further, but no one would argue the move's safety with a straight face even if, as an owner, I might do the same thing myself... I'm just a cheapskate who carries tire patches along with me). Using the model of auto tires, a tire manufacturer or shop gives a percentage credit for the unused portion of your defective tire, which in this case is essentially zero. @JCJ keep an eye out for the front tire. It could go, or be just fine forever. If you do have a failure on a tire that has wear left on it, visit the Facebook group and post pics just like you did here. If its an issue that rises to a warranty service level the admin staff will tag in a member of the Sondors team who will help you personally.
  23. Hmmm. Well, how about taking the meter out of the picture? I usually use an XT60 on the charger and xt60's on the meter so I can run without the meter if I decide to do so (you can just turn the bike on and read the LCD in a pinch). Looks like you used Andersons on both sides so assuming that will work. I use exactly what you are using for my 52v batteries and have stepped down to 48v no problem... so its not the charger unit. NOTE TO PEANUT GALLERY: To save time we went to chat and discussed the situation directly. Battery is at 49v, Manx Mariner has already tried taking the meter out of the picture and has also tried dialing the voltage back to 54v - to his formerly working 48v charge setting that he was using on a 48v battery. Nada. Charger still works on his 48v battery. So that seems to take the charger out of the picture and point to the battery having an issue with its ability to charge. He's working with the battery vendor to diagnose further.
  24. @brassell31 if you are going to pay for an upgrade, you may as well go all the way. You have to pay for a new caliper height adapter, and you have to pay for a new rotor... so make them 203's front and rear. You won't be hurting anything and its better to have too much capacity than too little. If too much, just don't squeeze as hard. In reality 203's front and rear are not going to make the brakes too grabby... the reality of a 50-60-lb ebike means that will never happen. Something to consider: Magura Storm HC rotors are super thick. 2.0-2.2mm thick. Lots of others are a lot thinner. About $28 each on Fleabay delivered. Interestingly enough, your current 160mm Tektro rotors are very nice. They have the same thickness as the Maguras, which is unusual. By way of comparison, Avid rotors are often in the 1.3mm thickness range. I re-used my Sondors stock rotors on my Stumpjumper - that I put a 3000-watt Cyclone on. Stopped freaking great with the AVID BB5's I had on that bike.
  25. @Chad Lauterbach In terms of fitment I have no idea. The FalconEV web site does show a pic with dimensions you can use to take your best guess on that. I actually have two Luna bags on my other two bikes and have found them to be of good quality. I used them when I couldn't fit the very large FalconEV bag... which I have actually had sitting around for over a year waiting for a frame it would fit into. So the Luna bags have been my go-to's for quite some time. They hold up well. But in terms of sturdy construction the Falcon bag is the champ of non-custom ebike battery bags ... its only drawback being its large size. based on what I have seen of them, FalconEV is making them smaller generation-after generation. The picture on the home page is the 3rd gen and thats mine. If you root around in their site you will find a pic of the 2nd gen and the measurements in that pic are larger. I have seen the 1st gen measured out elsewhere and it was larger still. Here's one of my bikes with the Luna bag on it. This bike only uses that bag for storage (my traveling Satiator charger which is no lightweight) and as a rats nest (wires) so its not quite stuffed full. Note I did not use the rear straps around the frame but they are used to hold onto the motor cables running up the seat tube. Looking at this pic, I am thinking the triangle of the Thin is too big for this bag given the already tight fit and the plunging top tube.
