Garmin Varia Radar compatible

You already have the phone.
Get it on the bars.

Your iPhone is the bike computer. Your Apple Watch is the heart-rate sensor — no strap. Plug in a Garmin Varia and cars land on a live tape: green, amber, red, their speed, a watch buzz/haptic, and faster beeps as they get closer. BigVelo is the crew chief that keeps just the info you need, right where it needs to be — on your bars.

01 · Your kit

Phone on the bars.
The watch on the pulse.

BigVelo treats the iPhone like a bike computer, not a camera you ignore. Speed, heading, heart, weather, the map drawer. Night graphite when the trail goes dark. Daylight glass when the sun is on the bars — same cockpit, two atmospheres.

  • iPhone is the computer — dashboard, map, radar, climbs
  • Apple Watch is the heart-rate sensor. No chest strap.
  • Start, pause and end from the wrist. Hands stay on the bars.

02 · Behind you

Your Garmin Varia just got a cockpit.

BigVelo daylight dashboard with radar tape at 360 feet and a red closing wash

Pair it and the road behind you is no longer a guess. Every vehicle lands on the tape — range, color, speed — with faster beeps as they get closer and a haptic on the watch when the tape goes hot. Same glass that holds your speed holds the car at 360 feet.

  • Amber approaching, red when they close fast — plus their speed
  • Faster beeps as they get closer. A watch buzz/haptic when it matters
  • The tape follows you: dashboard, map, climb, wrist

03 · Ahead of you

Bring the line.
Ride it.

Export from Trailforks, RideWithGPS, Komoot, Strava — if it’s a GPX, BigVelo imports the track. Ride To if you want Apple to draw a new one. Then the turns speak and the climb page arms itself.

  • Import any GPX — Trailforks included
  • Ride To for a fresh Apple cycling route
  • Spoken turns that duck your music
  • Climbs auto-switch when the grade starts
Ride story elevation, speed, and heart-rate charts after a ride
Apple Watch with BigVelo recording glance, heart rate, radar clear, pause and end

04 · On the wrist

The remote you never
have to hunt for.

The watch is a glance and a remote — not a second computer. Heart rate from the wrist. Radar tier on the status line. Start, pause and end pinned at the bottom so a rider mid-descent is not scrolling for PAUSE.

  • Heart rate without a strap — the watch you already wear
  • Pinned remote: start, pause, end stay put
  • Radar threat shows on the watch the moment the tape goes red

05 · After you stop

The ride still lives.

Map, traffic passes, speed, elevation, heart rate, the weather you rode through — and a GPX you can take with you. Laps you cut. HealthKit gets the workout. A BigVelo backup is rides plus preferences, for this app.

  • Ride story: the four numbers you quote, plus every pass on the map
  • Export GPX to open the line somewhere else
  • History stays yours even if the trial ends

From the bars

Night graphite. Daylight glass.

Dark is the night ride — trail plates, ice numbers, the story you open after. Light is the noon cockpit — white cards, orange MPH, a red wash when a car is closing. Same product. Two atmospheres. These are the real screens.

The whole cockpit

Every surface that earns the ride.

Not a teaser. This is what ships — dashboard through backup — so you know exactly what thirty days unlocks, and what monthly, yearly, or lifetime keeps.

Live dashboard

Speed hero, metric tiles, map drawer, START / PAUSE / END. Portrait and landscape. The numbers a rider stares at stay huge.

Swipe pages

Dashboard, climb, map, radar. The radar page exists only when a radar does. Climb auto-switch never yanks you off the map.

Rear radar tape

Varia compatible. Amber approaching, red closing fast, vehicle speed, watch buzz/haptic, faster beeps as they get closer, green all-clear, edge wash. Overlay — never a stolen gutter.

Ride To

Type a destination. Apple cycling routes. Preview, commit, follow. Clear the route when the day changes.

Trailforks + GPX

Import the line you already have — Trailforks, RideWithGPS, Komoot, Strava, any GPX. Export the ride you just finished. The line travels.

Voice that ducks

Spoken turns use Apple’s voice-prompt session. Music stays. Radar tones share the same claim so neither side kills the other.

Climbs

Planned climbs on a route. Live detection on freeride. Grade, remaining, splits. Auto-switch when a categorized climb starts.

Weather

Chip on the status row. Forecast sheet. Temperature unit independent of miles or kilometers. Stamped into the ride you already did.

Wrist vitals

Heart rate from the Apple Watch you already wear. Glance of the phone ride. Pinned remote. Radar tier on the status line.

Laps

Manual LAP any time. Auto-lap every so many miles or kilometers. The story keeps every split.

Back to start

The way you came is the way home. Retrace the line you rode — not a fresh guess.

Units that stick

Imperial or metric everywhere — speed, distance, elevation, radar ranges, history, watch. °F / °C chosen separately on purpose.

HealthKit

Finished rides can land as workouts. Heart rate you earned stays in Health.

Backup

Rides plus preferences, for this app. Restore adds missing rides. Export GPX when another app needs one line.

History never locked

When the trial ends, recording and live sensors stop. Past rides stay here to view and export. Keep BigVelo to ride again.

Keep BigVelo

Thirty days. Then pick a door.

The whole cockpit for a month — radar, turns, voice, climbs, watch, the ride after. Nothing held back. After that, recording and live sensors stop unless you keep BigVelo. History stays yours either way.

$4.99 /mo
