Wahoo Fitness  TRACKR RADAR Cycling Radar and Taillight

A fantastic alternative to the Garmin Varia. Mine stopped holding much of a charge after about 5 years of use so it was time for a replacement. I was disappointed to see that not much had changed, but saw the Wahoo at REI and really liked the design. The quality of construction is excellent and the mount is very nice, and the top and bottom lighting is definitely more visible than the Varia. I had no trouble syncing this unit with my Hammerhead Karoo and I think overall performance is much better than the Varia as this unit seem more responsive and accurate, with fewer false positives.

Great product! I have a few Wahoo products… Elemnt Bolt and Tickr heart rate monitor so it made sense to incorporate this safety feature within my Wahoo ecosystem. What a sense of awareness the Trackr brings me while on my ride. I know the number of cars behind me, how close they are and the best feature of all for me is when the screen goes green and I know that the coast is clear behind me for at least 150 meters. I’m now a convert to the value of radar while cycling!! Buy one and you will be glad that you did!

I was a little hesitant to purchase the RADAR and thought of it as a gimmick initially but this works so well. Nothing replaces actually turning around to check for cars but this is an additional tool for safety. I'm sure future iterations will work much better (cars approaching on parallel roads, or trucks will show as two vehicles). Setup was extremely easy, basically turn the thing on and it works. I still don't think this is a necessity but if you have the money might as well help enhance your safety.

This is a great accessory everyone should have if you ride a bike. The set up is easy and I’ve found the accuracy great. I bought this as a replacement for a radar I had from another brand. The other brand had many false positives while the Wahoo is more precise.

The 1-star rating is not about the device; it is about the experience. I have switched from the Garmin infrastructure to the Wahoo infrastructure for biking and fitness, and I can totally say that Wahoo is way better and more seamless than Garmin. I love Wahoo products since I made the switch! However, I cannot actually review this light as it is caught up in the quagmire of the OnTrac shipping system that REI uses. No updates for 4 days. No customer support. Nothing. Google the OnTrac yourself and you will see the crazy negative reviews. REI is GREAT, but ONLY BUY IN PERSON FROM AN REI RETAIL LOCATION! I thought I was being loyal by ordering this from REI. I have been punished for that! I could have easily bought this from Amazon, but I thought I would support REI. MISTAKE! If you cannot get to an REI retail location, then just go to Amazon or your product's e-commerce site, instead to make the purchase.

It shows me how many cars are behind me, and how close they get, continuously. It lets me know when there are no more cars at all, and when a new car shows up! It cracks me up with continuous streams of cars when I am in a highly trafficked area, but out in the boonies it is sure nice to know when no cars are behind me and when one or more show up.

Very effective. Helps me to feel much safer on the bike.
