Garmin Varia RTL515 Radar Tail Light - Rearview Safety for Cycling
The Garmin Varia™ RTL515 Radar Tail Light is a must-have safety essential for Colorado cyclists riding on busy roads, shared paths, or near traffic — providing reliable rearview radar detection of approaching vehicles up to 153 yards (140 meters) away, combined with a bright LED tail light visible from up to 1 mile in daylight.
This compact, easy-to-mount unit pairs seamlessly with Garmin Edge cycling computers (including the Edge 550, Edge 850, and Edge 540 Solar), compatible smartphones via the Varia app, select Garmin smartwatches for haptic/voice alerts, or third-party apps like Ride with GPS for overlaid radar data on maps.

Complete your Ride
We had an outstanding experience at Cyclerie! We purchased two Aventon e-bikes, and the entire process was exceptional from start to finish. The staff took the time to help us choose the perfect bikes for our needs, recommended all the right accessories, and even installed our bike rack on the car before we left.
I had a terrific experience at Cyclerie! I love the bike I bought and working with Skip was great. He told me about customizing features that are available on the bike if you use the Aventon app.
I enjoyed my buying experience at Cyclerie. Ideal location, easy to get to, easy access to trails to test ride. … Salesperson was helpful, knowledgeable and easy to work with. No pressure to buy.
