Assuming you want to get the girl you have two options:
1. fast track seduction - do something playful which brings attraction
like cycle back to her, ask her to stop for a second because u got something important to tell her.
when you are not cycling, you can tease her anyway you want, you can tell her you liked her nails..
e.g "i saw the way you cycled and i wanna hire you as my personal driver.. u can take me from home in the morning and drive me to work"
it could be projection, teasing, etc..
qualify
number close
..
2. slow track - it means that you will say "hi" and next time u say also hi.. eventually u will get to situation when you have small talks and u can escalate from there.
i'd go for slow-track for girls u see on regular basis.
i like cycling btw! cheers
