It looks like it was 3D printed.
Trigger Style Throttle for Ebikes?!

I always use 1/2 twist left hand throttles, as they have a built in cruse control function.
Just squeeze the 2 parts together, when installing on a Bafang motor, without the plastic insert, there is enough friction to hold whatever throttle setting you choose, against the return spring, sure makes it easy to travel 25+ miles on one setting 12.5mph per gps, and never touch the throttle, once set. You just have to remember to shut it down when you finish riding, and the first thing I do is grab a hand brake on a strange bike. ymmv

Well, what else would you do with a 3D printer early in the morning?

I concur with others - the thumb throttle can get a bit painful after a longer ride. Fortunately for me, my ride home is up 5 km of road, gaining 200 m elevation, so the throttle is pinned the whole time. Fortunately my 'bar grip moves a bit, so I pin the throttle and push the grip up against it to hold it there for 15 min. Hillbilly cruise control

Here's a dashboard photo of my Urban Stealth (semi-street legal) setup. I'll provide additional pictures to my Urban Stealth Build post as parts arrive. On the way to the park, I rode 20mph (while pedaling) on the bike lane and +30mph on streets. Very pleased with the setup and performance.
Edited: The next day, I took it to the park and pushed the controller to its limits, and the results were much better.
*GPS Verified* 35 mph or 41 mph downhill (215-pound rider). The speedo is accurate till 25 mph; it reads 45 mph while I was traveling 35 mph.

The thumb throttle supplied with my BBS01B kit required too much travel for full activation. This led me to angle it acutely upwards, which let in rain (UK) eventually killing it. There's no throttle on my bike anymore - not required because of how my BBS01B controller's firmware parameters have been programmed - but I do keep one of these push-forward throttles in my mobile toolkit for unforeseen emergencies. It clamps over the handlebar, so there's no need to pull things off to install it. I've replaced the securing hex bolt with a knurled thumscrew, for rapid tool-free deployment. Much less of a strain to use, also seems more waterproof.
p.s. The reason why my BBS01B doesn't need a throttle, is because the "Keep current" parameter in firmware is 100% of 18A at level 9, which is pretty much the only level I use - my bike is essentially a throttle-less 648W 20" wheeled moped activated by easy ghost pedalling. Legal in the UK, because the law doesn't say how many amps a 250W manufacturer rated motor's controller can draw.

The two-way aspect of the thumb twist is unique. I’m tempted to replace half grip two-way throttle. The wheel seems not as comfortable

I wish more handlebar attached components had this kind of attachment mechanism style... especially brake levers. I have one single brake lever from an old bmx bike that has a hinge and I can pretty much never find levers besides interrupter levers with hinged mountings.
