I hope it's okay to ask this here. I am wondering if there is a way a first rider could communicate directions or what is ahead to a second rider behind and do it hands free. My first thought was if both riders were using earbuds they could communicate through a phone call. Then I wondered if there is a multi platform iOS/Android walkie talkie app available. I found some but they seem like they all work like an actual walkie talkie where you have to push a button to talk and let up on it to listen which defeats the hands free requirement. The whole idea is to be able to communicate without having to take hands of the handle bars.
Has anyone else thought of an idea of communicating with another rider(s)?
