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.
6 speed: easy to use and perfect for the city and bike paths. There are enough ratios to gradually build speed without forcing too much. Not great for steep hills, ok for medium grade climbs. - Derailleur: Shimano Tourney
