The brake lever has no adjustment. Down by the wheels, each brake has what appears to be a standard Sturmey-Archer drum brake cable adjustment mechanism, but its hard to access and nearly impossible to adjust. Its also partly covered by a rubber part presumably designed to keep water out, which is itself hard to get out of the way.
