Hi everyone this is my first post and also ebike. Can anyone tell me if there’s and possible way to extend the thumb throttle?

?? I don’t under stand what you mean

There's usually a small PC/phone repair shop in many shopping malls. They can lengthen a cable for you, if you bring it in, if this is what you are asking.

What DW (more knowledgeable than I) is saying (I think) is there are three wires in a throttle. Either extend them by soldering a piece of wire to each, or have it done by a repair shop.

But if it is a brand new ebike, the throttle wire should be perfect already. Are you putting on higher handlebars?

Check with ATV dealers. I've seen a thumb throttle extension for a 4-wheeler before. It was a piece of plastic that was longer and easier to press that clamped onto the original thumb throttle.

Thank you guys for the guidance.
I was talking about the plastics throttle piece itself. I was able to extend it with aluminum Pieces
And drilled a couple of small holes to
Hold in place. I have small hands lol
