  1. Greeting Sondors fans and owners, This is a great place to learn about my Sondors Step. Thanks to all for sharing your knowledge and experience. I will try to chip in whenever I feel I have valid information. Purchased this bike for physical therapy. I am a new Sondors Step owner from upstate New York. My first thought was to get the most powerful ebike I could. Second thought, what if I didn't like it? I had not owned a bicycle in 15 years. Decided to buy a lower cost ebike just to see what it was like, and if ebiking was really for me I could always upgrade. Sondors Step only $975. A great bike at an awesome price. I am short of inseam and have limited ability to climb aboard, so the Steps low stand-over height is literally just what the Dr. ordered. I am very happy with the performance of the Step. I use the factory default settings at this time. So far I have added front and rear lights, a rear rack, left side mirror and a bell. Ordered and received a second battery from Sondors. Batteries are swapped about every 1 1/2 weeks. The battery not in use is stored at about 40% capacity then fully charged just before reinstallation. This bike now has 249.3 miles on it. Weather permitting I try to ride 10 miles minimum each day. Physical therapy is Ok. Fun is number 1.😎
  2. Hi Sondors community! My name is Roy, 30 years old and live in the Netherlands. I will use the bike for commute to work. Round trip is 20km (about 12 miles). After debating back and forth I finally went ahead and bought myself a Fold Sport. Here in the Netherlands we have dedicated bike lanes that are overall in very good condition. So no need for suspension or fat tires. Ordered the bike on the 10th of may and recieved it yesterday 15th of may. Talking about a quick delivery !! Very excited about recieving the package I cancelled all my plans for yesterday evening so I could start the assembly of the bike. With the help of the video's on the Sondors website this was a easy task to complete. In about an hour or so the bike's assembly was complete. Wow this bike looks even better IRL!! In 1 of the video's they gave the tip that you should first charge the battery. This way it should be charged when you finished the assembly. Followed step by step the method to charge the battery. Saw the led indicator on the charger blink green,red,green,red a couple times. Left it in the charger and went ahead to assemble the bike. When the assembly was complete i checked the battery and the LED indicator was showing a solid green. Already charged? Came pre charged from the factory? Sweet!! After unplugging the charger step by step I went ahead and put the battery in my bike. Turned the rocker switch on the battery to 'on' and powered up my LCD by holding the 'i' button in the middle on the controller. The excitement was real........ my first testride was about to happen......... Except on the top left of the LCD there was a blinking and empty battery indicator?!?!? How? I just charged it and the LED indicator was showing green = full battery? Since it was only on charge for about 1,5 hours or so I decided to but the battery back on the charger for another 3 hours. But unfortunatly when I tried it the 2nd time i was greeted by the same empty and blinking battery indicator? What a bummer!! Test drove the bike but there was no power. Not what I was expecting from my first E-bike! I contacted the chat via the Sondors website and they adviced me to make a technical support ticket. So I went ahead and did that! I am sure this will be just a minor thing that can be fixed but it is a bit of a bummer! DId any of you experienced the same issues? How did you get it solved? If someone has any sulutions on how to solve this I would like to hear about them. Thanks in advance everyone. Kind regards, Roy P.s. sorry for my bad English grammar haha
  3. Hi everyone, Apologies if this has been asked before but while searching on the forum I couldn't find that specific info for my setup. I'm about to order a new battery as I'll soon be working "far away" from where I live. I have a fat Sondors 2015 with the 250w stock motor and a Storm Hot Rod 25amp controller from Luna Cycle. I want essentially to increase my range, but I wouldn't mind a bit of extra power as long as that doesn't hurt the motor. So my question is, am I better off buying a 36v battery with 17 or 20am, or would it be fine to buy a 48v 20ah as per the link below ? I'm thinking, if I need to spend that much on a battery I might as well treat myself, but once again I don't want to end up replacing the motor in a month from now. I would be riding something like 16 miles per day (go and return), and I am not really willing to upgrade the motor as it's already barely legal where I live (I might not be tolerated as well if I'm riding even faster) . Thanks in advance for your suggestions ! Yann https://www.amazon.co.uk/gp/product/B07QYQQK8K?pf_rd_p=330fbd82-d4fe-42e5-9c16-d4b886747c64&pf_rd_r=XW1F5VB70PMA5GQTYCNV
  4. I am unable to turn the battery key that came with my Sondor's. See the linked video. Would welcome advice on what might be wrong and/or how to remedy the situation. https://photos.app.goo.gl/skTzajQQiRNPdMDj8
  5. I got home after a ride 2 days ago and my battery was down to 20% so I plugged it in to charge but the charger light stayed green and the battery was not taking a charge? I contacted Sondors tech service ( Sean ) and he emailed me back that it was probably a blown fuse in the battery. A 90% chance that was the issue he said. Has anyone checked and or replaced the battery fuse on their Fold X ?? I am pretty handy with electrical fixes so if it is not too difficult or VOIDS the warranty I am glad to do it myself and save the time involved with shipping the battery & charger in for service. Any feedback on this would be much appreciated. Felipe in B’ham
  6. In LA area. Cant mail. Collect only 4 no. Bottle batteries 14ah 36v. One year old. 4 of them 2 sondors 2 luna highest output Paid 1400$. Will take 1000$. Will split But not selling one by one. 2 or 4 at a time only
  7. So I decided to go for a 52v upgrade on my Sondors Thin using the Luna Cycles 52V TRIANGLE PANASONIC GA 18650 14AH HIGH POWER AND LONG RANGE battery. I carefully measured and I thought I could just barely get it in to my Sondors Thin if I took out the bumpers for the stock battery and some of the cable guides. I got the battery and even after looking it I thought it would work (see attached photos). I used a Dremel to take out the bumpers that were in there and most of the cable guides in the top right. The battery looks like it was made for the box, dimensionally it fits like a glove, but (and I knew this was going to be the tough part) the hard box on the Thin just won't quite close even after my modes. I don't think I'm close enough to quite get it there either. I really like the look of the hard box case on the Thin, so I'm trying to figure out it: Is there some alternative idea to getting this thing to work in the stock box. I'd thought maybe there's some way to modify the hinges... or even cutting off the outer rubber on the battery might save a few mm. Any ideas folks? That's why I'm posting on the forum. Is there another form of hard box, maybe from the non-Thin Sondors, that might fit in it? Is there something dumb I'm just not thinking of here? I guess the final option is just remove the box and put in a soft triangle bag (such as the Luna Cycles one). Does anyone have any experience putts one of those on the Thin? And once I do that I might as well get an even bigger 52v battery, right? I've also got photos of it compared to the ElctroBikeWorld LT48. Appreciate any input anyone has. Thanks! @Reddy Kilowatt?
  8. I have owned a Sondors Thin for 24 hours after 6 months of thinking about it and 3 months of waiting for delivery. Assembled,plugged battery in (green light). They charged it at the factory? Thanks! Twenty fun miles later the battery won't charge and I am deep in buyer 's remorse. What should I do? Green light but the battery is down to one bar.
  9. Hi all, I thought I would share some of my findings regarding Luna's KT-LCD3 and P5 - Power Monitoring Mode. I have the basic Thin with an upgraded screen and controller from Luna Cycle. Once hooked up, I notice that the battery level on the screen did not match the battery level that's on the battery. Once down to 0 level on the screen, I can see there's still some power left on the battery. So here's what I found. If you get to the P5 function on the screen, you'll find that you can change the setting from 0 to 12. For the Thin, I've seen 5 as a default. So off for a ride I go, having a great time, and later found myself down to nothing on the screen. I've figured that I've drained the battery down for the low voltage protector to kick in. Bike was a tank to pedal and had about 2.5 miles to get home... along with a few hills. I then remember someone saying that if you set the setting to 0, then you can get a real time of the batteries voltage. Sure enough, the meter showed 1 bar and was able to get the controller above the low voltage protector for the bike to move. I also noticed that if I set the PAS to 2, the low voltage would kick in as well as using any throttle. So as long as I left the PAS to 1, and provided and extra effort in peddling, I was able to get home. I also want to note that if you set P5 at 5, the battery level drops at a faster rate from 2 to 1 as compared to 4 to 3. YMMV
  10. You may have seen some ads here for the product "Booster Battery" for the SONDORS eBikes. We highly warn against these batteries they are really dangerous. Connecting two different batteries together may/will cause the weaker battery to drain first to the point where voltage becomes zero, at this point the battery will be damaged forever with no way to repair it. That may be fine for some of you but, here comes the dangerous part. The larger battery will continue to draw from the weaker battery which have already been exhausted and it will get extremly hot - a extremly hot and exhausted battery will explode and burst into flames. You are getting yourself and other lives in danger when you're connecting two batteries that are not the same voltage and amp hour. You might have been doing this with no negative effect yet but obviously you have not done long term testing. If it was this simple, someone would have done this along time ago. Lithium batteries in general are extremly explosive and highly flammable especially when you are not utilizing it properly. Here's a video of what happens when lithium batteries get hot:
  11. Hi there, I have had my Sondors Thin for 6 or 7 months. Recently I have noticed the battery is not holding a charge like it used to. Wondering if anyone knows what I should expect. Previously a full charge would get me to work and back twice before needing a charge. I could charge it up and leave it for 2-3 days and then take it to work again. Now it seems if I leave it without charging for more than a day the battery will go down to no charge (from full) without riding it. I always follow the charging instructions. When I do leave it over the weekend I leave the battery in the bike connected but turn it off. Is this just the battery getting old or is this expected? Thanks
  12. I would like to confirm if the attached is the right charger for a Sondors Original (fat bike) from Oct 2015. I haven't used the bike at all and parts were lost/misplaced when I moved. Any help/insight would be much appreciated.
  13. Can stock controller handle 48V? Can the stock controller handle a 48V battery? I guess fully-charged it can get as high as 54V. What would happen if a 48V battery was installed without changing the stock controller? Would the controller melt? Short out? Put out a motor sine wave that's clipped? Ruin the motor? Or would it handle it and there would be no problems? Has anyone tried this?
  14. Living way out in the suburbs, I need more range to get anywhere fun in this town. I decided to chuck the little 8.8 ah bottle battery, and install a triangle battery, and while I'm at it, why not over volt it to 48v? You can find these triangles in different ah ratings. 20 ah would probably be more than enough for most people, but I opted for the 30 ah 48v. Physical size is exactly the same whether 20, 25, or 30 ah. Right off the bat, your biggest obstacle is relocating the controller, which will be in the way. I decided to mount mine on the seat post tube, between the seat post and the tire. A good alternative position would be on the front down tube. In either position you should be able to mount the stock controller without cutting any wires. I used some left over mounts from a china girl motor bicycle kit to mount my controller. Next you'll need to fabricate a support to hold the battery weight off of the plastic box. This was pretty easy compared to mounting the controller. I used a piece of aluminum raw stock, a couple of washers used as spacers to lift the support to the proper height, and a couple button head bolts to hold it to the down tube, same as the stock battery cradle.
  15. I have had my Sondors Thin for about a year now & use it daily to get to work/home. I started noticing the bike was having trouble staying at full speed when the battery was running low a few months ago, it would keep me running at 19 instead of the full 20 when the battery was at about a quarter charge left(one bar on the screens battery indicator). Since then it has gotten progressively worse and is now down to only holding me at 16 with a low battery, when the battery is full the bike performs like it did straight out of the box but only for the first quarter of the battery or so. I have kept the bike factory except for the tires & inner tubes, I am running tubeless on the front & the standard setup on the rear at the moment, doesn't seem relevant but was advised to list any mods. I am wondering if anyone can point me in the right direction for troubleshooting this problem, I am thinking it is the controller going bad because I have taken proper care of my battery per the instructions that came with my Sondors & the fact that it performs perfectly fine when the battery is full but I would like to get some other opinions on the matter before I start replacing/upgrading anything.
  16. The purpose of this thread is to display the various parts of the Sondors Original electric bicycle. These diagrams are meant to annotate all parts on the Sondors Original ebike with an eye towards defining terms for the complete beginner. Have a suggestion for improvement? Post a question in the forum so all can see and contribute. This thread is a reference work that is closed to replies to keep it tidy. Try clicking on an image and bring it up in a new window. These started out life as high resolution images and can be seen larger in their native format. The Frame Here we point out common terms for the Sondors frame. These terms are common to all bicycles and ebikes, and you can use these terms in any discussion of cycling, anywhere. Bicycle Components Here we list the parts attached to the frame, above. We can't point to every single part but we have hit all of the highlights Components - Rear Zooming in on the back to label a few things not easily visible in the full bike view. Components - Front Zooming in on the front axle area to see some details on the brakes. More importantly, if someone wants to see your Sondors' nipples you don't necessarily need to call the police. Components - Middle Now you know the bottom bracket means two things depending on what you are pointing at. And the 'spindle' is the axle of the cranks, and hold on the crank arm via the crank bolt (which takes an 8mm hex key wrench that you should check every so often to ensure it is still at about 35 ft lbs of torque). Plus with this enlarged view we can see the 2-pieces that make up the PAS system a lot better.
  17. This information applies to: SONDORS Thin eBike (all variants), SONDORS Fat eBike (all variants), SONDORS Fold eBike (all variants) and SONDORS X (all variants) Great, you've got your new SONDORS electric bike. But you cannot find the keys for the battery? Don't panic! Here are two possible locations: In the Battery/Controller case, between battery or controller or In the foam packaging of the battery Didn't find them? Please carefully search in the shipping box / shipping material. They are not big so you could overlook them quickly! You searched for the keys in every possible location over and over again but couldn't find them? Please contact support@sondors.com for help. Ride safe! Andi
  18. Hi there, I hadn't used my sondors thin bike for about 3 months, and when I went back to charge it, the plug sparked when I put it in the battery, and will not charge. I bought a replacement charger, (not a sondors official charger but a charger with similar specs) but it will not recharge. The battery still holds charge from when I had charged it prior to the 3 months, but will not accumulate charge now. Any suggestions? Should I purchase a sondors official charger? Or is it a battery issue? Thanks! Edit: After checking the fuse, its seems to be still intact. Any ideas?
  19. This summer I came across a potentially bad issue, the factory did not properly tighten the wires inside the battery holder. Only once while riding did my battery mysteriously cut out for a minute and seemed to work again for several rides. I was removing the battery one day (I don't normally do that) and noticed the wire seemed slightly loser than it should be. I unscrewed the small plate on the bottom of the battery holder and found this: Those are lock nuts and do not move on their own if tightened properly. They are immediately behind the two spring battery contacts in the battery holder. This thing has been rattling around and sparking up a storm for several rides! As you can see, it was partially melted from the added resistance and charring. I would encourage everyone to at least give the battery cables a little wiggle and listen for any looseness. If you are suspicious at all, you need to first remove the battery holder from the lower frame with the two alan screws, then use a small philips to remove the small connection cover. Also, you must put a pin or tiny screwdriver through the hole in the battery spring contact to prevent it from turning before attempting to tighten the hex screws for the wires. If your wire IS fried like mine, first remove it completely and clean off any charring with a wire brush. Make sure the two can't touch and short when back in the holder, add some electrical tape if necessary. Here's a quick video as well: IMG_2501.mov
  20. I am really confused about the specific instructions required for charging the thin. I am very curious about why the charging requirements are so strict and what is at risk for failure if the process is not followed. First, it is very important to turn off the battery switch before charging. Well I forgot to do just that, my charger is hot and the battery didn't charge. Did I cause damage? What is actually being electronically switched within the battery enclosure? Second, it is important to plug in the charger to AC only AFTER the bike has it's DC jack plugged in. I really rarely do this. The charging block is bulky and the plug is hard to move. What damage does this cause? This isn't something I have every heard of with other electronics. I know a little about lithium batteries and charge controllers, I build my own electronics projects and things. These procedures feel weird to me with my experience in DC electronics and probably put in place to cut costs on proper safe electronics. My overarching question is what are these weak points that require these additional steps, Is it a cheap charger, or charging component within the battery that add's these steps. What damage is caused for having the charger plugged in with the battery turned 'ON" What damage is potential for having the DC jack plugged in after the AC power was applied? Thanks
  21. I'm looking to buy a spare x battery 48 volt 17.5 amp triangle , SONDORS doesnt offer one for sale yet! Imagine the range with two spare batteries in the rear panniers , SWEET ! CHEERS...
  22. Battery Dead? I have a Sondors Thin that has been working fine since I bought it over a year ago in May. Today it wouldn't turn on. I have the Luna LCD and it would flash for a half second then go dead. The battery test LEDs on the battery itself will not light either. I tried swapping batteries to my wife's thin (with no LCD) and it does the same on the throttle LEDs (flash for 1/2 sec then nothing). It's been charging all day. All connections have been triple checked. Is it a goner? And if so, what options might I have to repair or replace... this is my commuter bike! Thanks
  23. battery ah advice if i had a custom battery thats 36v 26ah, with pedal assit at 1 or 2, does it sound right that i should be able to get at least 180-300 ride time????
  24. Spare emergency battery 36v 8.8ah from 2 scooter batteries... Extra riding time cheaply.... Even use the stock charger as well...
