Throttle Assembly?

Where can i buy a new thumb throttle assembly for my Sondors Fatty? The LED lights have never worked on mine since I bought my bike about month ago. Sondors doesn't sell them on their site.

Jim if you choke on that price, try one of these:

I use the 'minimal thumb throttle'.  That is Kyle Chittock's site and his supplier is Wendy Xie at Passion EBike.  If you are willing to wait a few weeks, you can order directly from her on AliExpress for several bucks less.  I have bought from both of them.  

If you use one of these, they have no on/off switch so you just use on/off via the LCD.  Strictly speaking this leaves the controller 'live' which over time supposedly will run down the battery.  However I haven't detected any drain over a span of a couple of days (since I ride so frequently I have a hard time testing thoroughly).   If you let the bike sit for an extended period you might want to put in an actual on/off switch, or hold your nose and buy the Sondors switched throttle.

I got one of the "minimal thumb throttles" to replace the broken one on my Fold X. Surprise, it has a 6 pin male for the Sondors 3 pin female. So where do I get a throttle replacement for the Sondors Fold X??  Jim in Md

This might help:

”This is good information, but let me complete the picture. The green wire controls the throttle lights. The yellow and blue are switched power for the 6 pin throttle. If you want to keep the three pin throttle that comes with 7 speed bikes but attach it to an aftermarket controller, you cut off the connectors and do the following:

1) Attach the blue and yellow wires from the controller to each other. This means the throttle is "always on" and doesn't require the switch that doesn't exist with the 3 pin throttle

2) Attach the white, black and red wires from the controller cable to the same color wires on the 3 pin throttle. They color match.

 3) Tape off the green wire because there are no lights on the three pin throttles that Sondors uses”

 Hope that helps

I worked on my Thumb Throttle last night.

Standard thumb throttles located to the left of the brake lever assembly, make for a long reach. Thumb throttles located between the grip shifter and the brake lever assembly move the brake lever to far left, two finger grab? I came up with a down and dirty solution.

The 3D printed Extension is affixed with dab silicone sealant inside the extension, then pressed into place and allowed to set.

“FOR A MORE ERGONOMIC THUMB THROTTLE LOCATION”

I am adding these 3D Part Renderings, along with a Screen Shot of the SLA 3D print generator. These renderings also shows a "Thumb Depression", that was added to the part (shown on the top-left side of the part).

I always start with a relatively clear 3D printed parts to check for fit/interference before the final part. It was important to see how the four small clips/ramps interfaced with the underside of the Thumb Throttle.

If you have access to 2017 SolidWorks and a 3D printer, send me your email address, and I will send you the part and SLA file. You may need to modify the part to fit the Thumb Throttle on your SONDORS bike.
