Hi friends iam using I smart from 1 year and my experience is good with it but if you ride this bike above 50 kmph then tha mileage of the bike is get low and you will be get nerves but if u service this bike every month then you get good mileage like 70 to 75 kmph and it was good mileage and one dissadvantage of this bike is that the bike is unstable on a long bridge because the bike is made quint light weight because of is mileage if ur budget is above 70k then u will choose this bike for good mileage and brand.
