Long time listener, first time caller here
So I will try to keep this short...
Bought a used fatty a year ago and it sat in storage for a bit over winter... I took it out and tried to move it, and the rear wheel was locked up and wouldn’t go backwards.. Have been poring over this page and the Facebook page and I’ve gotten pretty far but now I need some advice
I’ve replaced the throttle (the button was broken so was needed), and upgraded the controller (it came with the bike so I figured why not while I’m at it...) I didn’t think those were really solutions, so no surprise when that wasn’t a fix.
Ao now the throttle works. I press down, the voltage is reading in the lcd and I can hear a “click” in the motor. But no response/movement otherwise....
am I correct in assuming this is a motor issue? Have checked all cable connections and they are good. Tested the battery, it read at 38 when off and went up to 40/41 when on... so seems like battery is good...
I thought I might take it apart and check, the Luna motor instructions made it seem like a simple 3 step easy removal.. so I finally removed the rear wheel and then got to “Remove the sprocket...”
I’ve read everywhere that removing the sprocket will destroy it soooo... before I destroy my sprocket and take apart my motor... are there any other issues I could check?? Or am I right in assuming it’s a motor issue?
the sprocket is pretty rusty... there’s a good amount of rust in places there probably shouldn’t be rust.... I have some simple green cleaner/degreaser but would really appreciate some advice on removing rust tooo!!
And I guess while I’m here, and if it’s needed, can anyone recommend a good replacement sprocket/motor?? Is luna good, despite their instructions are not so simple as they seem? what confuses me is that they don’t think you will need a new sprocket, or is that included?
Thanks for listening y’all, hopefully my bike isn’t a total lost cause...
My lcd has just died on my Fold sport from water damage I'm quite sure so this is my perfect opportunity to upgrade I have been looking at the 750w bafang rear hub motor and they say it will lace in 350w motor no problem but I have the 250w bafang rear hub motor. Will it fit? But first I want too upgrade the sondors lcd to the ktc3 25 amp and 25 amp controller and will wait till sondors have the 48v 14 amp available in Europe until i upgrade the motor as the 38v 8.8amp battery won't be powerful enough. Any suggestions or problems with my plan I would appreciate feed back
Hello everyone, I currently have an Original Sondors Fat Tire bike from 2016 (I believe). I purchased it from a friend who had performed some upgrades to it.
As the bike sits today:
Luna Storm 48v 20ah Battery Controller Model KT36/48ZWSRMD-SLSLD02 Rated for DC 36v or 48v, Rated current 12A Maximum current 25+-1A (Assuming this is from Luna as well) Original Motor Bafang RMG06 36v 350W(10) 26-1-1508195560-6 LCD Luna LCD Dashboard for Sondors KT-LCD3 Took the bike out for a ride the other day after it had been sitting in the garage for about a month and received a motor hall connection error on my LCD screen. Tried the usual unplugging the connection under the chainstay and making sure I had charged the battery. I'm wondering if I am able to replace the cable coming out of my motor (if that is the culprit) or if I need to replace the motor altogether. If that is the case, would anyone recommend I upgrade to a 48v motor? Would it make a difference/ work with my existing upgrades? I'm new to the forum and Ebike scene in general so I appreciate any help. Thanks!

SONDORS X arrived on January 7, 2019.
Living in Southwest Florida has made it easy for me to ride every other day. I am recovering from a bone on bone knee with a damaged medial collateral ligament.
After a full year of daily PEMF treatments and two Prolotherapy injections, my Prolotherapy doctor recommended that I start exercising using a bicycle to stimulate the natural lubricant within my recovering knee joint. I started exercising with a standard road bike, but was not able to “Spin” with minimal effort as instructed. I own a 2010 electric recumbent trike, but is it is next to impossible to get in and out of a bike several inches off the ground. I recall seeing the SONDORS advertised several years ago and decided on the SONDORS “X”. I use the thumb switch to move the Fat Tire “X” up to 16+ miles per hour, then put the bike into 7th gear and move the pedal assist to Number 3, this allows me to Spin at the optimal level, without causing stress on my knees. I started with five minutes the first week and I have added five minutes per week, I am now at 20 minutes, and this technique has allowed me to build muscle riding it every other day. I have been able to move the pedal assist down to number 2, my goal is to ride on Fort Myers Beach after I have built enough muscle in my legs. My target for the beach is early March!
My SONDORS X is a very well-built fat tire bike and has been the perfect platform for my recovery! I don’t see myself going back to my electric trike or the road bike, the sign on my front lawn, “BIKES FOR SALE”
Thank you SONDORS!
P.S., Super easy to accessorize
