That is why I prefer to use an adjustable bike stem (0-90 degrees) to bring the handlebars closer. It doesn't affect the folding capability, and it allows for adjustment for different riders. There is no adjusting by just rotating the stem, It is what it is... and if I recall, it's about a 6" difference, and to some riders, that's too much. However for short riders, the 6" difference is fine.
