Yeah, those uphill pedalling! My legs hurt on the first times I pedalled my dad's pedicab. But he does it all day, under the heat of the sun and even during rainy seasons. There's more passengers when it floods, so more moneys. But greater risk.
It's totally up to you. I don't really mind, I'm just glad I could share some, even very little, to this kind of initiative. Cheers!
