Frequently Asked Questions

What is the Garmin Varia RearVue 820?

The Garmin Varia RearVue 820 is a rear-facing cycling radar and taillight that detects motor vehicles approaching from behind at up to 140 metres and alerts you via a compatible Garmin head unit or the Varia smartphone app. It is the successor to the Varia RTL515, offering improved radar performance, a brighter taillight, and longer battery life.

What are the key features of the Garmin Varia RearVue 820?

Key features include: radar detection up to 140 metres; taillight up to 82 lumens visible up to 1 kilometre in daylight; multiple light modes (solid, flash, peloton, night flash); ANT+ and Bluetooth connectivity; compatible with Garmin Edge 550, 850, 1050 and other Garmin devices; Varia app for standalone smartphone use; up to 16 hours battery in radar + flash mode; IPX7 waterproof; and approximately 54 grams weight.

How does the Garmin Varia RearVue 820 radar work?

The RearVue 820 uses radar to detect motor vehicles approaching from behind at up to 140 metres. When a vehicle is detected, a visual alert appears on your paired Garmin head unit or Varia app, updating in real time as the vehicle approaches and passes.

What head units is the Garmin Varia RearVue 820 compatible with?

The RearVue 820 is compatible with Garmin Edge cycling computers that support Varia radar, including the Edge 550, Edge 850, and Edge 1050. It also works with the Varia app on iOS and Android smartphones.

What is the battery life of the Garmin Varia RearVue 820?

Battery life depends on mode: radar + flash mode up to 16 hours; radar + solid mode up to 6 hours; taillight flash only (no radar) up to 24 hours. Battery life varies with light mode settings and conditions.

Is the Garmin Varia RearVue 820 waterproof?

Yes. The RearVue 820 is rated IPX7, meaning it is protected against immersion in water up to 1 metre for up to 30 minutes. It is fully suitable for riding in rain and wet conditions.

How do I mount the Garmin Varia RearVue 820?

The RearVue 820 mounts to your seatpost using the included mount, supporting standard round seatposts. For bikes where seatpost mounting is not possible, a seat rail mount kit is available separately from Bikers.SG. The device must face directly rearward for optimal radar performance.

Can I use the Garmin Varia RearVue 820 without a Garmin head unit?

Yes. The Varia app (free on iOS and Android) allows you to use the RearVue 820 paired to your smartphone, displaying radar alerts on your phone screen during rides.

How do I pair the Garmin Varia RearVue 820 to my Garmin Edge?

Power on the RearVue 820. On your Garmin Edge, go to Settings > Sensors > Add Sensor. Select Lights or Radar. The Edge will scan and detect the RearVue 820 — select it to pair. Radar alerts will then appear on your Edge screen during rides.

What is the difference between the Garmin Varia RearVue 820 and the Varia RCT715?

The RearVue 820 is radar and taillight only — it does not record video. The RCT715 adds an integrated 1080p rear-facing camera for incident recording. The RearVue 820 is lighter with longer battery life and is the better choice if video recording is not required. The RCT715 is recommended if you want ride footage for safety evidence.

Does the Garmin Varia RearVue 820 replace the Varia RTL515?

Yes. The RearVue 820 is the successor to the Varia RTL515, offering a brighter taillight (82 lumens vs 65 lumens), improved radar performance, and longer battery life. Bikers.SG stocks the RearVue 820 as the current model.
