I used this bike since 1 year. The bike is awesome at all. U should try this bike on road it gives more comfort.
The bike will not unsatisfy you with the mileage issue because the mileage is 60kmpl and fuel capacity is 5.3 liters which is sufficient for you to travel in city. The space given in activa 4G is more sufficient for keeping anything inside it.
The bike has stylish body which indicates the stylishness on road.
So u should definately try this bike, it just awesome
