Hehe... Silly me. Went to visit a bike builder last summer to build me a rickshaw to use to investigate local tourism biz. Eine lokale deutsch-kanadischen that fambilates bike, trikes and carts in his own tiny "car free town". This guy:

Specs included 500lbs of passengers and their gear, riding in something like this:
Weight of rickshaw includes sunshade, ashtrays, bucket of chilled... whatever. Night lighting and cooler fridge, wattEVer. Includes also two brakes and a sound signaling device. Or two. All dragged behind/connected to battery-electric bicycles (summer students, etc riders). Local taxis are regulated "up the ying yang", so... "tips only", but having handy paper cards from various ebike shops. Any/all cards that show up at area retailers (and translate into a new customer)?, Rickshaw Grrrl (or Guy) gets a "kick back" aka commission.
I would expect a guy familiar with "heavy use" bikes, carts, etc. to "over-build", on the theory that "heavy" (well built) vehicles cost more in components, etc. Think "warranty" where higher up front costs hopefully replace lots of maintenance costs, etc.
(Objective? Get young folks REAL business experience. And especially *fun* while they're doing it. NOT a "Mac Job".)
(Oh yeah. And make a small net profit after taxes. For all concerned.)
G'Luck with your "pedicab from China"!
