The cycle rickshaw, which is a variant of a cargo bike is quite common in Asia. The price for a new one ranges from $100-500. Meanwhile, a bike with elongated rear rack, e.g., a longtail cargo bike (barely counts as cargo bike) can cost $1,000 in the West, and that is the entry level “cargo bike.” A front load cargo bike costs $2500 and upwards. An Urban Arrow ™ cargo bike can cost a whopping $6-7k.
This region is a major training area for professional cyclists. It causes a lot of friction with drivers who act aggressively in response. Road riding should be safer than sidewalks, but culturally here it isn’t. On sidewalks I have a higher risk of being hit by drivers turning/pulling out so I just slow down at each crossing and always let them pass me.
