I bought Activa 4G few months ago and it ran 450 km till now but didn’t face any problem with the scooter except the mileage, it gives mileage of 35 - 37 where as company promising of 60 km. So think twice before you chose this.my bike batry was low .cheape milage.the hero shorum deler is not responce for my bike problem. Bike battery is not good.battery water was overflow.
