This inner tube is very similar to the original tube in my ebike, including the bent valve tube. It seems to have the same thickness, and there are no leaks.It also has a great price for the no so common tube/wheel size.

The inner tube is fine, standard quality. I don't like the look of the bent valve stem but it does make it easier to access in a small wheel. Seems like there are better values out there, with some two- or multi-packs being offered for just a bit more money than this single tube.
