Works great !!!
I've installed a lot of throttles on e-bikes. Fed up with full-twist throttles molded-on horrid grips and ugly housings that interfere w/ my shifter and brake levers placement, I uninstalled my Domino 0 - 5 ohm to find a thumbie. In conjunction, I replaced the JST plug on the controller, soldering in a Bafang Julet fitting cord and (I've published the entire process on 'endless sphere') determined the wiring. I have a couple full-twist Wuxing throttles. Very nice performance but an ugly grip on my beautiful machine. They really hit the mark with this one. Much higher quality materials and construction than other thumbies and I like that it's only 0.8" wide. My brake lever placement is now easily adjusted to my tastes. Since I rarely use throttle but shift constantly, I mounted on the left side and my shifter on the right is now perfectly ergonomic, and my brake levers/ shifter fit just right. On street testing (Class 3 Bike) I find the bike's noticeably more powerful than with any others throttles I've tried. It pulled clear up to 24mph, not the usual (pedelect) 20mph max. It should also be pointed out JST (fittings and) wiring standards are for fixed applications - LED lighting, Computers and such. Being bombarded with sudden shocks, they suffer intermittent failure. Julets are specifically designed for e-Bikes, so I replaced the 26 size JST's with 22 Bafang wires. The wire this throttle uses is (bafang plug) is exactly right. It's tough and the correct gauge. Strip black outer-sheath at 12. Perfect. No damage to three-inner wires insulation. Inner wires strip at 22. No torn strands. Never use a blade to try and cut the outer- sheath, or strip it down the wiring. 12 on the strippers. There's usually one common colored wire, so it's simple to ascertain the other two (GND or Signal). I've clipped those two in reverse numerous times an zero damage to my electronics. If display (1) shows error message; (2) throttle won't work; or (3) motor jumps into to full-throttle mode: Turn off at display, reverse wires and restart and it works. Features I like. The weight. It's light. The design. I'll be doing some more real-world testing, so the convenience of being able remove the throttle without having to remove my brake lever and grips is a big deal time-saver. The geometry and adaptability of configurations. Best I've found. Three six-mile rides and it seems the power input is about same as torque at my pedals. The power ramp up is a lot better than my $175 Domino - even after installing resisters. Placement, either side of my brake lever works fine. No thumb stress whatsoever and no interference with anything. Buy this before it's banned. It's that good. Ride on !!! If you have longer or shorter thumbs, or prefer two finger brake position v fuller hand on the lever, it makes it easy to experiment. but my impression thus far is it's the best yet and Wuxing has hit a Home Run.

love this thumb throttle!
Love this thumb throttle let's me keep a consistent flow of speed . I tried the twist throttle for a bit , but I fond that some time it slid through my grip.

Same as Super73 OEM thumb throttle, only with SM/Higo connector.
We ordered this for a Super73 that has an upgraded controller and thus required the different connector. We were able to compare this one side by side with the Super OEM thumb throttle and they're identical. Good quality, heavier duty than others we've had that broke. This one also has a nice long cord to go all the way back to the controller under the seat. Highly recommend this one!!

Worked without rewiring
Worked perfectly with Swytch Max++. No rework of wires. Plug and ride. Make sure to get extension wire.

Wolf king GT pro has 2 be modified
The throttle response feels smoother than the original. But you have to cut the wires. Black goes to black. Purple goes to Gray, then Gray goes to purple. Very simple fix and best of all. It has my scooter back up and running.

Small adjustment made this an EXCELLENT upgrade
As this throttle comes, it is not directly applicable to my Kaabo Wolf King GT scooter. However, upon switching and reconnecting the pink and grey wires to the plug (pink to grey and vise verse, black stays the same)- this is a MUCH improved throttle to the throttle that originally came with the scooter. This throttle feels much more solid, is much less prone to engage accidentally, and even applies power to the motors in a much improved and more reliable way and without that awful “dead zone” the original throttle has. I suggest it strongly. Note to manufacturer: business could definitely be had to have those two wires the other way to advertise as a plug-and play throttle upgrade.

Didn't work!
Dislike cause it didn't work. Thought it would work on my yume swift throttle electric scooter. Thought it was compatible. My Bag for not seeing the word bike.

Great quality
This throttle has a much sturdier feel than others that I’ve seen. It does so, without adding a lot of weight. It is rather robust, taking up some space on the bars, so I’d consider fit with other accessories. Such as, brakes, speedometer, or phone. Overall, I’m happy as a clam with this throttle.

I'm using this with my Swytch kit. This is really excellent - as first I was a bit annoyed because it came with the wrong connector, so the description could be more clear. But actually I'm not sure that would have worked for me anyway as Swytch seems to use the connectors in a proprietary way so i have to figure out which cable did what. Once figured out and jointed it works sooooo much nicer than the Swytch one and the way it mounts to the bars is nice and sturdy, again, way nicer than the crappy overpriced Swytch on. Would buy again and would recommend for Swytch users

Fits electric bike perfectly

Works well, smooth power delivery. I needed to use an adaptor to fit it to a Fiido twist throttle wiring setup, but other than that can't fault it. Have been using it for a month without problems, and it's been caught in the rain a couple of times.

great bit of kit this.

Plugged straight in and works well. Replaced a twist throttle (on pedaleze e-bike kit) which was becoming flakey. Many thanks.
