Hi,
Recently I purchased this bike Activa 3g. It has a 110 cc engine and gives a mileage of roughly about 55 - 60 km/l within the city.
Its great for within the city rides. Its very comfortable to ride in busy traffic as well. The bike is safe for anyone to ride.
The handling and comfort is pretty smooth.
The moment I think about gear less bikes, this one comes in my mind first. The look of the bike is also very stylish
If you are looking out for gear less bikes, I would strongly recommend Activa 3G.
