My father bought this bike 3 months ago for me. It is a very good bike. It gives mileage of about 80 kilometers per litre. It also have a power start which is very helful during jams and traffic. After using 3 months it is in very good condition.The i3 system is fuel efficient system which helps to increase some mileage.In terms of power its engine is not that powerful but is enough for daily rides.
