I Want to Go Bike Riding

I like going bike riding these days.Yesterday and the day before yesterday I spent about twenty minutes to ride a bicycle along the road,I have never rided1 ( the past tense form of ride is rode) rode a bike since I worked later (no need for you to add/use the word later its already understood that it is past) The feeling was so happy when I rided on a rode a bicycle.

I told myself I must stick to ride I must ride regularly,becuase because it keeps me fit, it is a sport 2 (you could also write it this way "because it is a sport that keeps me fit")

When I rided on a bicycle I sang 3 ( this phrase can also be written this way "every time I ride a bicycle I sing) ，4 I could see streetlights and,  pedestrians and cars.

Explanations:

3. If your action is habitual like the example above, try using every time or regularly.
