Age is just a number for 87-year-old Mandakini Shah and her sister Ushaben, who zoom around the streets of Ahmedabad fearlessly on their scooter, earning the nickname 'Biker Dadis'.

Videos of Mandakini, aka Mandaben, riding a scooter with her sister, Ushaben (84), sitting in the sidecar, have gone viral on social media, with people comparing them to Jay and Veeru, characters portrayed by Amitabh Bachchan and Dharmendra in the Bollywood cult classic 'Sholay'.
