I'm getting no reading on my battery gauge and no pedal assist beyond level 1, although I can set it to any level on the screen.  Also see "Sour 2" at bottom of screen, which I assume is an error code, but it seems like error codes are usually numbers, and I've not been able to find any reference to this in forum nor anywhere else. Has anyone else experienced this "Sour 2" error code?  Any solutions? I'm waiting to hear back from Sondors tech support...

Since you edited in the picture that’s a KT-LCD3.  Have you programmed your display?

Neither the KT-LCD3 nor the KD51C, displays that were shipped with the Sondors X have any such error code. LCD3 have a 01 & 03 but no 02. KD51C displays have only two digit error codes, all in the twenties.  The Sondors X was shipped with either of these displays depending on the manufacture or ship date. 





I’m not sure what your seeing (never had Sour or 5our reported before) or which LCD display you have but previous problems with No Battery Indicator displayed, have generally been a bad controller or LCD, and most commonly with the newer KD51C.  Sondors has replaced them on recently purchased bikes.  If you don’t have the current mph  displayed or if the current mph was intermittent, those symptoms were of a bad controller. 

Most often, Owners have replaced  both the Controller and LCD, due to compatibility, them selves, when upgrading their Sondors for better performance to the 25amp hot rod controller and the compatable aftermarket display.  The switch adds a few MPH and much better torque and acceleration. 

Sondors now forces you to join Facebook for support.  Since your Sondors was purchased last year, and about a year old, my recomendatiin is to save yourself a lot of time and grief and spring for the aftermarket upgrade. It’s about 110$ for the pair.

      I purchased four Sondors and love all four but I love my wife more and she believes we have two too many Sondors so I listed two on the Atlanta, GA Craigslist. I purchased two Fold X, one Sondors X 7 with suspension & LCD and a Thin 7 with the LCD-suspension & the battery upgrade. The Sondors X and the Sondors Thin both are too tall for my wife and almost too tall for me. The Sondors Fold turns out to be the best fit for us for the type of riding we do. I discounted the Thin a little more because I would rather let it go rather than the Sondors X. I am trying to sell the Thin 7 at my cost minus the shipping and LCD Screen cost and the Sondors X at my cost minus the shipping. If we would have been able to ride the Sondors before purchasing we would had discovered the two were too tall and would have only purchased the Folds. If I do not sell the Sondors X I plan to strip the drive system and install it on one of my recumbents. If you live anywhere near Lagrange, Georgia and are interested in a Sondors bike but would like to ride one before purchasing any Sondors bikes contact me and I will try to arrange a test ride even if you are not interested in purchasing mine.  I do not have any other experience with electric bikes other than the four I own but I cannot imagine any others being much better than these except more size options.

      I'm looking for the Canadian Government required compliance sticker to put on my new X (for Ontario Canada.) 
      Our government is kinda goofy about this trivial minutia.
      The requirement is,     " What is a Canadian e-bike compliance label required to include?"
      Sample label:
      The Canadian highway traffic act expects the manufacturer to put this on the bike where it is visible in  both English and French.
      If Sondors  won't help with this I'm going to photoshop one with the required info.

      Hello all. I just got a Sondors x fat tire bike. It has the 17.5ah battery as opposed to the original with the small 8.5 or something like that. My question is ..do any of you know how it would work if I got one of those 54000 portable ac outlet power banks. They are only a few pounds and you can plug the Sondors charger in it and Maybe connect it to the bike as you ride and it pulls its power from there before it takes it from the battery. These power banks would hold about three full charges if I do the math correctly. Any thoughts about this ?

      Sondors X 7 just arrived 8/8 -Assy report
      Just put together the Sondors X, Silver frame and rims, with Suspension, LCD Screen and 7 speeds.
      Arrived by UPS freight (Colorado Springs). 2 packages bike + LCD screen.  Well packaged, took 1:45 hr to assemble, did not need instructions as I previously put together my Sondors Original.  Well protected no scratches, left crank arm pedal thread was buggered up, cleaned out threads with a tap, rear wheel badly off center, striped m4x1.0 screw in grip shift housing (my fault) replaced with new screw.  Has a guard to protect the derailer during shipping- label said to remove. Put battery on charger during assembly fully charged in 2 hours.  Love the silver metallic paint. Both tires at 16 psi.
      Last hour of assembly was to center rear wheel, adjust brakes, adjust derailer, bent kickstand out for greater stability,  build was no big deal as expected. Changed LCD setting to remove 20 mph max speed with motor assist.
      First Ride Impressions
      Very smooth, quite.  I love the feeling of a brand new bike.  Not sure 7 speeds is of much benefit, I think I'll leave it in 7 gear most of the time.  Max seed maybe 1 mph greater than my 36v Steel frame Sondors Original.  The 48V battery system will most likely add battery range vs 36V.  Suspension seems a little harsh- do not see if it is adjustable.  No noticeable difference in hill climbing from my 36V Sondors.  
      Only went for a short 10 mile ride as I recently hurt my shoulder.
      Overall as expected, great bike, great design, great value and tons of fun.
