In my school days, I used to have so many cycles, in every 25 months or so I used to change my cycle. My father used to get me only atlas cycles that time because Atlas cycles are very light weight, comes within budget and lookwise awesome.
Very easy to maintain and can get the parts easily. They do offer a huge range of cycles for kids, girls, boys and adults too.
From a large range of design and style, I had to decide any one every time and that was not an easy task.
