Fold X 7 Throttle Sensitivity Adjustment

Recommended Posts

Last week, I had a chance to ride my daughter's Fold X 7, as the ground still had quite a lot of unmelted snow.  It didn't ride as well on top of the snow as I had hoped, but it is much better than my other bikes for sure.

Anyways, while plowing through the snow packs, I've found her throttle literally is like an on/off switch.  It was nearly impossible to modulate the motor assist level other than mostly on or off.  I've tried different PAS levels, but the behavior didn't change.  Is there an LCD user setting to change this?

No.  Sorry.  For what its worth my 2016 Original is roughly the same.  And a Bafang fat hub motor I just installed in a new bike is pretty much the same story.  Leads me to believe this is something essentially built into the platform at a level far below anything Sondors can affect.

Here's something you can do:  C5=0 is undocumented but its a setting that allows full wattage to the motor but a 'soft start'.  On very powerful motors (52v especially) it makes for a much safer, lawyer-friendly experience.  With that setting, power rolls on slowly.  Its safer and once you get used to it allows a somewhat increased level of control, but its not a true fix along the lines of say acceleration curve mapping like you would get with an automobile PCM tuner.

I had another chance to ride the same Fold X 7 again, and I was able to modulate the throttle to produce different assist level (love that real-time watt meter on the LCD) with very sensitive and tiny adjustments.  With that, I concluded that the bike is taking the readout from the hall sensor but not mapping it properly.  If it is not possible to change the power curve from the controller side, maybe a different throttle could mitigate or solve this problem?  Hmm...

You'll have to just go buy more of them and see what you see.  In particular consider the Bafang throttle for the Bafang motor... although you are still running it thru a KT controller.  I believe velomobileshop.com and their Chinese parts source Pasion Ebike  are both offering it, although the velomobileshop.com picture of their 'minimal thumb throttle' is still the small teardrop paddle, and not the large ambidextrous paddle made by Bafang and originally sold only to the BBSxx mid drive market.  I have a couple of them but never installed them... they're just backups.

Be advised that since Sondors started installing these throttles on the 7-speed bikes a number of people have broken them off.  If you install one, set it so the wide-open-throttle setting is pointed straight down, so if you hit a bump your finger slips off harmlessly rather than crunching thru the paddle.  Thats how I set up my mid drive throttles and I have never broken one.

Yes, I have quite a few throttles in the parts bin, and I will experiment some when I find the time and motivation.  Thanks for sharing your experience on this topic.

      I'm putting together my seven speed condors thin and it looks different from the assembly videos in that there is no lighted up grey part on the throttle with a button.  The throttle is just a black lever.  Is this right?
      I did order the LCD screen and am installing it now.

      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.

      I took a superman flight over the bars in a contact event with an auto. I'm OK but my throttle got jammed up as I went over. Now I need to try to re-wire the inner parts, shown in the photo. Can anybody supply a wiring diagram for this throttle, or a photo that shows what colors connect to where? I can solder so if I know where they go, I can get it fixed! (I have another throttle on order from Sierra Bike—thanks for that link in a different topic.)

      Controller making noise & very low power
      Having some trouble with my Fat Tire. On a fully charged battery, the bike barely has any pulling power, and there's a noise coming from the controller. 

      Do I need to replace the controller on this unit? Any suggestions for shops in Los Angeles that are familiar with these?
