@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.

A3. We use handheld FRS radios to communicate during #eastbaykidicalmass rides, and we use them just like another poster mentioned - comms between leader/sweepers/corkers/mechanics/medics. Basic, cheap, rechargeable radios that are easy to use.

@Heyweldon @ascentale @skyfaller @bikenite A3) In case it helps, UK equivalent might be PMR 446, Australia has UHF CB (set to low power). #BikeNite
