Talk to the whole group. Even with no signal.

Kolvoy is a group intercom for motorcycle riders. It uses the helmet headset you already own, and your phones pass the voice from bike to bike when the cellular network gives up.

100m

Per hop, roughly. Phone to phone with phones in pockets. Every rider in between adds range.

0bars

No cellular needed. Where there is signal, Kolvoy also uses the internet, with no distance limit.

Hands-free. The mic is open, just talk. Push-to-talk is there if you prefer it.

One look tells you who is talking.

The ride screen is a status board, not a control panel. Who is talking, whether you are heard, and whether everyone is still with you. It reads in under a second, with gloves on, on a handlebar mount.

Your music keeps playing. It lowers while someone speaks and comes back when they stop.

No cellular here. The ride keeps talking.

On a mountain pass with no bars, phones link directly to each other and relay for the riders behind them. The app says so plainly: "Mesh carries everyone".

The honest limit: two phones reach about 100 m with phones in pockets, more with handlebar mounts and line of sight. A rider who drops out of range of everyone reconnects when they close the gap.

From parked to talking in three taps.

The lead starts a ride and shows a QR code. Everyone else scans it. No internet needed, even for joining.

SOS that travels rider to rider.

Hold the SOS button. After a 10-second countdown you can cancel, your group gets your location over every path there is. The moment any rider in the group has signal, your emergency contacts get a text.

What it is not: Kolvoy does not detect crashes and is not a substitute for emergency services. If someone is hurt, call your local emergency number.

Ride with your crew this weekend.

Free to talk. Works with the headset already in your helmet.
