Battery-free radar tail light for eBikes

This rear-view radar and tail light attaches to compatible eBikes without a separate battery, drawing power through a Garmin eBike cable sold separately. The 24 GHz radar detects vehicles approaching from behind up to 150 yards and pairs with select Garmin wearables, Edge computers or the Varia smartphone app. Cyclists who want automatic alerts without charging another device will find it suited to daily commutes and longer rides. Riders needing a self-contained battery unit or a model that works with non-Garmin eBike systems should look elsewhere.

IP65 weather resistance and low-power operation

The unit carries an IP65 rating, so it resists dust ingress and low-pressure water jets encountered in rain or road spray. Its compact plastic housing measures 1.6 by 3.1 by .8 inches and weighs 1.8 ounces, adding minimal drag or bulk. Because it draws power directly from the eBike system, there is no internal battery to deplete or manage, and the radar runs continuously while the bike is powered on. No fan or active cooling is present, so operation remains silent.

Four light modes and wireless updates

The tail light offers four selectable modes: solid, peloton mode, night flash and day flash, providing daytime visibility up to one mile away. Connectivity uses ANT+ and Bluetooth Low Energy to link with compatible devices, and firmware updates are applied via the Varia app on a smartphone or Garmin Express on a laptop. A universal seat-rail mount and a rack or pannier mount are included, allowing flexible placement on different frame styles. No additional software licences or subscription services are required.

Questions about this item

How do I install the 615 radar tail light on my eBike and which step do people usually miss?

Mount the unit using the included universal seat-rail clamp or rack bracket, then connect the supplied Garmin eBike cable to the bike’s power port; the step most riders skip is pairing the radar to their Edge computer or Varia app before the first ride.

What maintenance or replacement will the 615 radar tail light need over time?

The sealed IP65 housing has no user-serviceable battery, so no routine maintenance is required; if the unit is damaged or the radar sensor fails, the entire light must be replaced.

At what distance does the 615 radar stop detecting vehicles under sustained use?

The 24 GHz radar detects approaching vehicles up to 150 yards (140 meters); beyond that range the unit no longer provides alerts regardless of how long it has been operating.
