When there's girl walking and i ride behind her if i like her shape and want to see her face i just tap bell slightly making 1 short gentle ring and most girl look around and then we meet sights, i smile ride next to her and ask her for a phone number. or if she not my type i just ride on. So yeah bell is very useful.
You need to select a proper classic retro bell, not this modern silly sounding ones that dont even work same way as in the past.
