Comments:
City Bikes: They are designed for comfort and daily commuting, to go to work, to school, to go shopping, etc.. Compromise between performance, comfort and sturdiness. Often loaded with useful accessories increasing the weight.
3 speed: simple and easy to use, perfect for daily cruising around town on a rather flat terrain. Not so good for medium and steep hills, ok for smooth climbs only. - Derailleur: Shimano
Tires 26 x 1 3/8: narrow tires with small thread, for paved road, very common on older bikes.
