Years ago I built a cheap low power e-bike out of an old cordless drill. Used the drills motor and gear-box as it was with a single speed freewheel adapter welded to the front of the old key style steel chuck and mounted on the back side of the seat down-tube to drive the top of the chain above and behind the crank chain-wheel.
Worked okay but was low power, annoyingly load, and eventually the brushed motor gave up the ghost.
Anyway, the point is that I used the original variable speed trigger unit of the cordless drill just with longer wires soldered onto it and notched the handlebar tube and embedded it in the hand grip below and underneath the brake arm so the throttle was just like a cordless drill on the right hand hand grip. Just squeeze the embedded trigger to go and when you lifted your fingers up to grab and pull the brake lever they physically couldn't also be squeezing the throttle at the same time. Thus no need for throttle disconnect special brake levers or anything like that.
I'm wondering if I'm the only one to ever do a set-up using that kind of cordless drill trigger type throttle embedded in the hand grip (surely I can't be). Is real comfortable and easy to use with a very intuitive feel and I've tried with some although certainly not complete success to copy the same kind of set-up on some of my more recent builds that use modern brush-less motors and electronic motor controllers.
Anyone know if there is anyone out there selling such a style of e-bike throttle ready to use? Anyone, have a good sources for good quality variable pot trigger assemblies. I'm still salvaging them out of cordless drills and not all of them are suitable for conversion to e-bike throttles and its hit and miss.
Thanks in advance.
P.S. (added in edit) = Before I posted I did use the search function and all I got for trigger style throttles was single hand control units guys were building for electric skateboards not much if anything on trigger type throttles embedded in the grip for e-bikes.

(so pulling a trigger doesn't work for me, but pushing with a thumb does).
