While I have seen a lot of motor cycle modified taxis in Lima and other towns in the Sacred Valley (I do not recall if I saw any tuk tuk in Cuzco though), I saw another very unique transportation in Puno which I have never seen anywhere else in Peru. That is bicycle modified taxi. Just like motor cycle modified tuk tuk, the bicycle modified taxis also have three wheels but two wheels and passenger seats in front and the bicycle driver in the back. I think I have seen bicycle modified taxis in Thailand but it was first time to see such thing in Peru. Perhaps it is good for short ride around the town center, but I never tried.
