E-rickshaws everywhere in agra and way cheaper than regular tuk-tuks if you know the real rates. Taj east gate to agra fort should be ₹80-100, not the ₹300 they'll quote tourists. To sadar bazaar from anywhere central is ₹50-80 max.

The trick is to walk away when they quote double. They always come running back with the real price. Share with other tourists if heading same direction — I've split ₹60 rides four ways before.
