The CPSA of 1972, et al. The part on Bicycles is under 16 CFR 1512. Handlebars are under paragraph 1512.6(c). "Handlebars shall allow comfortable and safe control of the bicycle. Handlebar ends shall be ... no more than 16 inches above the seat surface when the seat is in its lowest position and the handlebar ends are in their highest position".
The CPSA applies to the Commerce (sales) of products, (and their testing), but it could be the local laws that control aftermarket changes and use on public roads - such as a rule relative to one's shoulder height.
However, the above part of the regulation might only apply to mechanically hazardous bicycles for children (12 years age or younger), as it actually stems from the "Child Protection Act" of 1966.
