There are millions of definitions for what street photography is, and I don't care! If you like it and think it is a street photo, it is a street photo. I constantly see people keep telling others what it is or not SP; their comments are just a full waste of time and space.
I really liked this capture. There is a strong subject and unlike what you expect from a cyclist, she is not riding her bike. Great use of shallow depth of field brings nice subject isolation while the subject is sharply focused with plenty of details. The silver car spoiled the scene, but when you are on the street, you compose what it gives you.
