Remember the bullock-cart or kereta lembu? I remember these carts were still lumbering through Petaling Jaya. One driven by a Punjabi man and his young sons used to pass by our house. He sold fertiliser (cow dung) around PJ.
As you know, the bullock-cart is an efficient mode of travel. But you'd need to make one, and find yourself a couple of oxen.
Or, perhaps you'd prefer to get one of these. They're commonly used in Amsterdam. Almost everyone rides them. But, oh...I forgot...Amsterdam is low and flat and the weather is so damn cool. And the roads are cyclist-friendly.
