I do NOT need the bicycle for daily commuting or mountain climbing. I need the bicycle for morning and evening exercise and just for roaming around in order to get some fresh air.
I also want a smooth ride on non-smooth roads. I am a female.
What to look for in a bicycle meant for the above described needs?
I searched for and found the following bicycles with suspensions.
They fall near about $ 103.
How do I know whether they are comfortable for exercise and roaming around?
I am an underweight female so loosing weight is NOT my goal. I wish to get mentally fit and therefore I wish to tire myself out without getting bored. They say physical exercise is necessary to get rid of depression. Hence I chose to cycle out.
The most important thing is that it be the right size for you, and after that you appear to want a "relaxed", upright posture rather than a "racing" posture. For that an inexpensively-built "city bike" (such as Andy's illustration) or perhaps a "hybrid" is probably the best choice.
Are the bikes shown above hybrid?
