@skyfaller asks:
Q3. What communications systems do people use for talking with other bicyclists while riding?
We used these Bluetooth helmet "radios" by Sena, and they were extremely helpful on long rides where we couldn't bike side by side, such as when we moved house by bike. But these were mediocre helmets, if either the Bluetooth or helmet dies you must replace both, and annoyingly you had to pair the helmets every time.
#BikeNite A3: Shouting.
I've been thinking how group ride leaders can stay in touch with the sweeps and corkers. Maybe a group call on cell phones? But not everyone has an unlimited cell phone plan.
Maybe whistles? The sweep can whistle twice to get the leader to slow down (spreading out too far is the most common problem I see on group rides), maybe three times for a full stop.
Are there standardized whistle codes for this kind of thing? ( #BikeNitePQ ?)
