today is my 15th birthday, and it is also the 10th birthday of my mini bike that I loved to ride when I was little. I remember that when I was five years old, I was given this four-wheeled orange bike by my father. The bike was only one meter high, but he also added two small wheels to the back wheel in order to keep me from falling off. Besides, he designed and assembled a nice small white basket. The bike was painted in a very prominent color -orange. I still remember when I was running around the neighborhood, everyone noticed and complimented my bike, and I was very proud of it. There was a special thing on my steering wheel, and it is a bell for me to click in order to alert other people, but most of the time I just used the bell because the ringing sound was very interesting. Now my pretty bike is no longer running, but I still take care of it carefully. Every month I wipe and examine it clearly, I am afraid of the thought that my bike will be broken because it is not just a birthday present but also a big memory to my whole childhood. I have considered this little bike as my sister as well as a part of the family.
