Your bike radar, shared with the whole group.
Domestique Hub reads your Garmin Varia (and compatible) rear radar and does something your bike computer can't: it warns every rider in your group the moment a car is closing on any one of you.
In the Domestique Hub app for iPhone & Android — a mobile browser can't reach Bluetooth sensors. A radar is optional: group rides, trainer control and tracking all work without one.
Why pair Varia with Domestique Hub
Group radar warning
If one rider's radar sees a car, the whole pack is warned on the live map — the rider at the front knows what's coming up behind the group.
On your ride screen
Radar sits alongside power, heart rate and speed on a Garmin-style dashboard — not a separate app to glance at.
Solo, too
Riding alone? Your own approaching-traffic alerts still show, recorded with the ride.
Everything in one place
Radar, smart-trainer control, a live rear-view camera and group tracking — one app, one screen.
How it works
- Open the Live tab and tap Pair a component.
- Select your Varia (or compatible) rear radar over Bluetooth.
- Start a group ride — every rider's radar now warns the whole pack.
Radar alerts support your own awareness of approaching traffic. They do not replace looking, and are not a collision-avoidance system — always ride to the road and local rules.
Questions riders ask
- Do I need a radar to use Domestique Hub?
- No. The live group ride, smart-trainer control and ride recording all work on their own — a radar just adds the approaching-traffic alerts.
- Which radars work?
- Garmin Varia rear radars that broadcast over Bluetooth, and compatible units from other makers. We show approaching vehicles and their position behind you; closing speed isn't displayed.
- Does every rider need one for the group warning?
- No — that's the point. One radar anywhere in the pack warns everyone on the ride, including the riders on the front.
- Does it work on an iPhone?
- Yes, in the app. iPhone browsers have no Bluetooth access at all, so pairing any sensor — radar, power meter, heart-rate strap — needs the installed app rather than the website.
