One brake on 3 wheels? This would hardly be safe with any sort of motor or engine anywhere. And if one rides in hill country it would not be safe with human power. I once rode a one brake trike that slid its only braked wheel down the dry paved road on which I live from a dead stop with me (all 220 pounds) on board. Brakes on every wheel are an absolute necessity on American roads.
