Planning to ask someone out

I’ve been ‘seeing’ this person for a while and things are going well. I plan to ask her out. We do a lot of bike rides in and around the city. We’re going out for a breakfast ride this Saturday. I’m planning to ask her out at sunrise. Problem? Can’t seem to decide a pretty sunrise place 🙂‍↕️ plis help! Don’t mind a 100 odd km ride but above that will be a little difficult!
