I recently bought hero ismart blue colour. It is a best bike from milage point of view as comparted to other bikes in this range bcz of its beauty with milage and enough power.
I will recommend this bike if you want a good milage with best looks. But if you want a power then go for another option though ismart is bit costly as compared to bajaj milage bikes but you will find good reliability and durability in hero bikes than bajaj.
