And I guess your passengers were larger than the average Cambodian! I am tempted to ask one of these guys to let me have a go pedaling - it's flat so I shouldn't embarrass myself too much.
Haha, yes, heavy indeed, and I averaged $10 a day averaging around 70-100 miles, worst business ever. I used to argue with rickshaw and tuk-tuk drivers when I first moved to Cambodia because they were carrying a lighter load than me, going a shorter distance, and also charging me 5 times more than I would've made in my own country. I am almost 100% sure they think I'm lying when I tell them I once did their job, but carried a 400% heavier load uphill for a 1/5th of the monthly income, haha.
The one rare upside is that when going slightly downhill the wind doesn't affect you because the momentum of all that weight keeps propelling you. Random factoid, once had a drunk passenger punch a guy on the sidewalk from my pedicab, talk about a legal nightmare.
