  1. Battery on 2019 Sondors Step will not charge. I plug the charger into it and charger light remains green (never turns red to indicate charging). I reset LCD to default just to make sure it want settings issue. Any ideas? I tried two different chargers as we ha e two of these bikes. When I remove battery and plug in to charger, 3 green dot lights turn on only when plugged in.
  2. Does anyone know how to correct this? My LCD displays 49.6 mph whenever I am coasting. The mph displays correct MPH whenever I am pedaling or using the throttle. 350 watt motor, 15 amp controller , 12.8 bottle battery, KT-LCD3 V1.0 4E 24/36/48V
  3. Commute to and from work... haul propane gas water & groceries uphill for my dry off grid cabin... Year round... In Alaska. Thank you Sondors... Amazing vehicle... Bravo!
  4. * The best way to use this video is to watch and write down the desired options, then exit and program your LCD. if you try and program while watching the video your LCD will timebout and none of the settings will be saved and you’ll have to keep starting over because of the length of Kyles explanations .

C4 = 0 (Handlebar Function Setting Mode, 0 - 4) C5 = 10 (Controller Maximum Current Adjustment Mode, 00 - 10) C6 = 3 (Backlight Brightness Adjustment Mode, 1 - 5) C7 = 1 (Cruise Function Setting Mode, 0 or 1) C8 = 1 (Motor Operating Temperature Display Mode, 0 or 1) C9 = 0 (Startup Password Setting Mode, 0 or 1) C10 = n (Automatically Restore Default Setting Mode, n or y) C11 = 0 (Attribute Selection Mode, 0 - 2) C12 = 4 (Controller Minimum Voltage Adjustment Mode, 0 - 7) C13 = 0 (Brake energy recovery - recuperation - only works with the corresponding controller, 0 - 5) C14 = 2 (Coordination of support levels, 1 - 3, 2 = standard) (description of the C parameters follows) Step by step / Details What you should now to set up your KT LCD3 display: General Settings: Under power off status, hold the „power“ button long, the meter is turned on. Within 5 seconds after boot-up, hold „up“ and „down“ simultaneously for about 2 seconds. Now you are in the settings menu. (between each setting parameter press „power“ to save and to get to the next parameter) Max. Speed: leave it For Europe: set it to 25 km/h to be on the legal side. Wheel Diameter: set it to what it is: 29 inches Metric and Imperial Units: your choice After finishing metric/imperial unit settings, the speed and mileage units stop flashing. Within one minute after stoppong flashing, hold „up“ and „down“ simultaneously for about 2 seconds to enter the P parameter settings environment. Need values for our motor are (http://www.szbaf.com/en/components/component/motor/rm-g06350d.html): Cadence (Pulses/Cycle) 6/1 Reduction Ratio 1:5 Magnet Poles 20 P1 Motor Characteristic Parameter Setting Mode P1 is motor characteristic parameter setting mode. P1 = motor gear reduction ratio x number of rotor magnet pieces, just rounding if there’s any decimal. Sondors: Ratio 5 x 20 Magnet Poles = 100 = P1 P2 Wheel Speed Pulse Signal Setting Mode P2 is wheel speed pulse signal setting mode. If wheel generated 1 pulse signal by a revolution, P2 should be set as1. If wheel generated 6 pulse signals by a revolution, P2 should be set as 6. If users didn’t configure the pulse signal system, and then P2 parameter setting can be 0. The setting range of P2 should be between 0-6. 0 : motor hall sensor only (speed is only shown while motor is working) 1-6: Pulses per Cycle Sondors: Cadence (Pulses/Cycle) 6/1 = 6 = P2 P3 Power Assist Control Mode P3 is for power assist control mode, when P3 parameter setting is1, power assist control mode is gear 5 of “imitation torque control” mode, when P3 parameter setting is 0, power assist control mode is gear 5 of “speed control” mode. P3 parameter needs to be determined according to the distributed function of the controller, its setting range is 0 or 1 Sondors: P3 = 1 P4 Handlebar Startup Mode P4 is handlebar startup mode. When P4 setting is 1, indicating the handlebar is under “non-zero startup” mode, namely, the handlebar can be effective only after startup the foot power assist. When P4 setting is 0, indicating the handlebar is under “zero startup” mode, the motor can be startup by the handlebar directly. P4 setting range is 0 or 1 Sondors: P4 = 0 P5 Power Monitoring Mode P5 is power monitoring mode, when P5 setting is 0, the power monitoring is the “real-time voltage” mode. Namely, it is the method to determine the battery capacity based on real-time battery voltage. When P5 equals to a specified parameter, the power monitoring is the “smart power” mode (this parameter is determined by the battery characteristics, ordinary 24V lithium is generally is 4-11, 36V lithium is between 5_15). P5 setting ranges from 0-40. E.g.: 9 = 24 V 12 = 36 V 15 = 48 V Sondors: 36 V -> P5 = 12 To exit the programming mode just hold „power“ some seconds. After finishing P parameter settings, the P5 parameter stops flashing. Within 1 minute after stopping flashing, hold “up” and “down” for about 2 seconds to enter the C parameter setting environment. C1 Power Assist Sensor and Parameter Select Mode C1 is power assist sensor and parameter select mode.

It is served as identification parameter of different phases of the motor when using sine wave drive and the default value is 0. When C2 setting is 0, indicating that the used Quantum motor phase is an ordinary one. When the setting is a certain value, indicating a particular motor phase is used. C2 setting range is 0-7. Sondors: C2 = 0 C3 Power Assist Ratio Gear Initialization Mode C3 is initialization mode of power assist ratio gear. The setting range is 0-8 (gear). When C3 setting is 0, the meter is switched on, and the power assist ratio is at gear 0. When the setting is 1, the meter is powered on and the power assist ratio is at gear 1, and so on.

  7. I purchased the August 2018 run XS Fat and received in Jan 2019. The admin password for advanced settings is 1515.
  8. need to know what "03 Info" means on my display i just jot my bike in December and already its giving me some weird code.... what does this mean - and how come you sonders is so lazy as to give out information on the LCD controller for my FOLD X. half of the codes and modes of the LCD are not described anywhere. At the moment i'll just settle ok knowing what a flashing " 03 Info" on my display means. Everytime i use the assist throttle on my FOLD X - i get this message and customer support for sonders has been pretty cruddy... can anyone here help as to what might be causing the issue. there is also a slight noise form the motor that i do not recall hearing before (but perhaps its just me).
  9. Hi I've just bought a pre owned fat bike, not sure of the exact model but it has the "Wendy" led controller. I inverted the bike to swap brake pads (being careful not to damage the controller) but it began to rain very heavily so I left it in situ and when I came back to the bike after a day or so I couldn't start it, yes the battery was charged? The screen was completely blank, no led's on the throttle. then after 24hours the lcd screen showed the 'boxes' where the information should be but just the boxes no actual information, this screen is visible even with the battery removed, so I'm thinking rain penetrated the lcd controller whilst the bike was inverted. Ive now opened the controller and left it indoors in the hope that it will dry, and will put it in a bag of rice to absorb any moisture from the circuit board, is there anything else I should try?
  10. Hello Sondors riders! Just want to show you guys and gals the new KT-LCD3 now with a USB port! It still looks the same, functions the same except it now has a USB port in the back so you can charge your phone or power your headlights. Has a 5v output with 2.1amp to charge the latest Samsung & iphones. See more information here https://electrobikeworld.com/products/kt-lcd3-usb
  11. Hi All....Merry Christmas! We received one X7 on 12/12/17 Charcoal/Blue and the other one Silver/Silver on 12/14/17. I ordered them September 1st 2017. We just received the NEW version of the LCD's today 12/23/17. Version A11111. I included some images of the screens There is a Walk button at the back of the LCD control switch. Be prepared, it takes off at about 3.5 MPH. The bikes are awesome. We are thrilled with the bikes. Fun fun fun! I swapped out the stock 4.9" mudders on my wife's X7 for Maxxis 2.5 Hookworms along with the tubes due to my wife's height.(5'2"). The height with the Hookworms is PERFECT for anyone wondering if a 5'2" person can comfortably ride the Sondors X. She was afraid of the 4.9's (To high), with the 2.5's she didn't want to get off the bike! Things I did/added: All add-ons I found on Amazon. The disk brakes were WAY out of whack. I had to adjust them on both bikes. Maxxis 2.5 Hookworms with Maxxis DH Downhill 26x 2.5-2.7 tubes. Planet Bike Big Buck front and rear fenders. Mirrycle MTB Bar End mirrors. MaxMiles Bicycle Handlebar Extensions. TANSOREN 4000 Lumens Eagle Eye Ultra Bright Waterproof Bike Headlight with CREE XM-L2 LED Light (Battery mounted in battery box with velcro) Blackburn 2FER Front or Rear Bike Light.

  12. I have an extra LCD B2222 36v, If you need it make me an offer.
  13. Still figuring out the Fold X LCD settings preference, but it seems the top speed setting will reset if the battery was powered off. Anyway to make it remember?
  14. After two months and 150 miles SONDORS Fold "X" LCD display do not show the battery level in the panel. Has anyone had this problem? everything works., less breast and battery in the LCD., before you could see and work everything.
  15. Luna Cycle's "preprogrammed" LCD and upgraded 20 amp controller combo Does anyone know if the Luna Cycle LCD and 20 amp controller combo is really a different LCD than an original (kickstarter) LCD? Can I just buy the controller and reprogram my existing display or do I really need to buy their display too? https://lunacycle.com/batteries/gauge/lcd-dashboard-for-sondors-bike-hot-rod-programmed-kt-lcd3/
  16. Does anyone have clear instructions on how to actually use the cruise control feature? The directions that come with the LCD panel are weak at best on how to actually use the features available.
  17. I just got my Thin. The assembly went well until the end - LCD cable installation. I found what appears to be the correct cable that goes into the controller (far side, unconnected cable, with a black end cover on it). The problem is that I cannot get the darn end cover off. I cannot get it to separate. In the videos it appears that it simply pulls apart. I pulled, pried, used my teeth, everything. Eventually, I think I broke the cover away from the green connector piece. The black cover seems to have simply separated from the green cap inside. The two green connectors never released - (the bike still works fine in throttle mode). But I cannot plug in my LCD cable because the two green pieces are still attached. My next step is a pair of pliers. Is there a trick I'm missing? Thanks.
  18. Hey guys so I have a question I hope you can help me with. I got an original fat bike last year (no LCD) and added the official Sondors LCD after. I love the bike, especially with the LCD, but I live in a hilly area and it lacks power on climbs, especially with my 185lb butt with a full backpack on it. I think a higher current controller might help the situation, but I understand there are some compatibility issues with the Sondors LCD and the controllers Luna cycles sells. Does anybody know how to identify what controller/LCD combo I have so I can look for a stronger controller that will work? Or is there a better first step for a power increase other than the controller upgrade? Thanks all.
  19. LCD Display not displaying speed, battery, etc Hi everyone, I recently received my Sondors and I can't figure out why the LCD Display is not showing speed nor battery life ? I can change the pedal assist level, the maximum speed, size of wheels etc but it doesn't show my current speed reading and the battery is completely blank, what could cause that ? I bought the display on Ebay, it's this model : http://www.ebay.ie/itm/141957087134?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT And the Sondors on their website (not on Kickstarter/Indiegogo). Thanks ! Yann
  20. Long story short: The generic LCD (KT-LCD3) that you can buy from a lot of vendors, and the "Wendy LCD" that you can buy from Passion eBike (AliExpress) and velomobileshop.com with the Sondors plug will apparently NOT work with your bikes from kickstarter. Sondors has apparently changed to a proprietary Ketung controller and communication protocol for the KickStarter bikes. Only the LCD available from Sondors directly will work with it, and you have to make sure you order the LCD for KickStarter campaign, because they also sell LCDs for the older IGG campaign bikes. What you can do: If you don’t want a LCD Display from Sondors here are a few options: Buy the 20A Controller from Wendy this one will work with your Bike & the generic LCD. If you want more torque wait for the 25A Controller which will be released soon by Wendy. This one will also work with your existing Bike & the generic LCD.
  21. Since the LCD user manual's chapter about the parameter copy fuctionality is a bit ambiguous, here's a step by step guide about how to set up the LCDs and the wiring. Disclaimer 1: In order to connect the two LCDs, you'll need to build an adapter cable by yourself! This requires some soldering skills, as well as some electronics tools for working on cable wiring. Disclaimer 2: I used third-party displays I had purchased from AliExpress. I DO NOT know if this works with Sondors branded LCDs or with a mixture of both, because of the various communication protocols. The user manual says that parameter copy is working with displays using the LCD3 communication protocol. As far as I know, the Sondors branded LCDs and third-party LCDs both used the LCD3 protocol. Step 1: Build your adapter cable Since the LCDs have those small round black/green male-type connection plugs, it is recommended to build up your adapter cable by using the opposite female-type connection plugs. Those plugs can be found on extension cables for the LCD for example. I simply took appart two spare extension cables and soldered the open end wires together, following the above image. Please pay attention to the cross-wiring of the green and yellow wires! Normally, every pin is wired to it's corresponding pin on the other side. In our adapter cable, pin 4 of the source display plug is wired to pin 5 of the target display plug (green line) and pin 5 of the source display plug is wired to pin 4 of the target display plug (yellow line). It is also recommended to put an on-off-switch to the red and black lines connecting the power source, such as the bike battery or any other 36V power supply. Step 2: Set the source display to act as a data source It is recommended that the source display is NOT password protected and the C9 parameter is set to C9=0! This setup should be done while the source display is still connected to your bike. In order to set up your LCD as source dislpay, you need to enter the programming mode and go to the C-parameter settings. Have a look at this post how to do this. Go to the "C11 Attribute Selection Mode" and set the C11 value to 2 (C11=2). Then finish the programming procedure. This enables your display to be the data source for copying parameters. If setting the C11 value to 2 is successful, the display should show the following after finishing the programming mode: Switch off the display and disconnect it from your bike. Step 3: Connect the two displays 3.1 Detach both LCDs from their bike's controllers. 3.2 Connect both LCDs using the adapter cable as shown in the image of Step 1. 3.3 Connect the adapter cable to the power source. 3.4 Switch on the power source. Step 4: Perform the parameter copy operation 4.1 Switch on the source display by pushing its on-off-button. 4.2 Switch on the target display by holding down the on-off-botton until it activates. Within 5 seconds after activation, simultaneously press the up- and down-arrows of the target display for at least 2 seconds. Then the copying process is finished. The actual parameter copying process as very fast and is done in an instant. If successful, the display should now show the following: Step 5: Finishing touches After successful copy, switch off both displays and the power source and disconnet all components. Do not forget to revert the C11 value of the source display back to where it was (probably C11=0). Hint 1: If the source display was password protected (C9 parameter), keep in mind that the password has not been copied to the target display. Hint 2: The C11=2 source setting of the source display has also not been copied. It makes no sense to copy this parameter to the target display. After re-installing the target display to your bike, it should work as normal again. However, it is recommended to check the overall programming.
  22. Hi Sondors Riders. Selling a gently used LCD Display. Reason I'm selling is that I ended up upgrading my controller and had to switch to a third party display. I had originally ordered this display for my Kickstarter Fat Tire bike, but installed it on my Sondors Thin and it worked perfectly fine. Can't guarantee that it will work for you as well, but to compare the setup, the controller part number it was connected to on my thin is KT36ZWSR-LD03. Kickstarter LCD Display in box (but also worked on my Sondors Thin) $60 + shipping US Only Local meet-ups in the San Francisco Bay Area are possible
  23. When I enter my security code and hit the middle button the display just shuts down. It worked great but just shuts down now please help. Gene
  24. I received a Sondors Fat Tire eBike as a gift. I have no way of contacting the original buyer to find out where the bike was purchased from. I desperately need to buy an LCD Screen system and controller to unlock the bike's full potential. Are there any serial numbers or markings on the bike that indicate where it was purchased from so I know which LCD Screen to purchase? (i.e. Indiegogo, Kickstarter, gosondors.com) Any help would be greatly appreciated!! Thank you!
  25. I installed it as instructed, but lcd is not registering all level. Battery is blank voltage is 0 Assist levels work well (bike is faster just not registering on display) GOT BIKE IN: NOV 1015 GOT LCD IN: MARCH 2016 THANKS FOR YOUR HELP DJPJNYC
