My 6 year old daughter and I sometimes bicycle together. She is 4 feet tall and has a 20 inch Specialized Hotrock bicycle. Occasionally we have to ride on streets (We stick to trails as much as possible). I would like to make her more visible to automobiles. As far as I can see there is no way to mount a trailer-style flag on her bicycle. I have mounted white and red flashing lights on her helmet but they are not that visible during the day and her profile is low on the road anyway. What are my options for protecting her on the road (and trails too)? Are there vests with extremely bright LED lights that would fit her? Is there a way to mount a flag on this frame? Thanks!
