For anyone that might take this comment as sound advice, please don't. Everything about this post is nonsense. Let's break this down.

1. Riding in the shoulder is, for the most part, perfectly fine and will provide a relative "safe zone" between you and traffic. Even better if you have a painted bike lane, and even better still if you have a dedicated bike lane. Depending on where you ride, weather conditions, etc., you may find it necessary to exit the safe zone and ride in a car lane. This device will allow you to make an informed decision on when exactly to merge safely. A flat tire is a far better option than getting rear ended from a distracted driver.

2. Taking a lane as default option is not only a dick move, but a dangerous one. You'll make drivers frustrated which leads to impulsive behavior, which can end poorly. "Peddling hard" might work in small bursts as means to remove yourself from an unsafe situation but don't count on that option on mile 20, 30, 40, etc., when your beginning to fatigue. At speeds in excess of 20MPH (possibly less) your ears won't be able to make out approaching cars due to wind resistance. Oncoming traffic will also drown out the sound of approaching cars. Hybrids and electric vehicles will be even harder to detect.

3. Be sure to mention your 6th sense to your medical doctor when they ask you why you enjoy playing tag with cars.

Having said all of that. I personally have the Radar/Light combo and it's been game changer. The battery life is fantastic. The light has a daytime, nighttime and peloton mode if you ride in groups. You get a different tone depending how fast cars are approaching you and it will integrate with your phones bluetooth if you (like me) can't yet afford a head piece. The only cautionary advice I'll give is it won't pick up objects moving the same speed as you. For example, if you're approaching a stop light, and both you and the car behind you are slowing down, it might give you an "all clear" tone when in fact the car is still there.

If anyone has any questions I'll be on for a bit. Youtube has some great videos on the unit as well if you want to see it in action.

Have a good/safe ride.
you are the reason people despise bikers. I'm saying this as a biker myself. everyone, please don't take this guy's advice
IMO, it's worth it to step up to the RTL315 for battery life alone. 6-7 hours on OP unit, 15 hours on the one with the light.

On RTL, You can turn off the light and keep radar active if you use it with a Garmin head unit. Most recent firmware may have made it where you can run radar only with wahoo, etc but I'm not sure since I use a garmin 1030 and 830.

Sweet price though, and if it suits your needs, I've never seen a better deal.

Not sure, but it's been retail for awhile then a month ago they dropped the 315 with light to $159 and this one with no light to $129.


But the 315 has gone back to $180. Not sure how much this one was prior to the sale.

No light ... No deal.

Do you really want 2 devices on the back of your bike? No.

A light is mandatory if you're riding on the road day or night. Don't be an organ donor too soon.

I recently bought the one with the light to give it a try. I thought it was a gimmick, but I honestly can say it is a very useful gadget. After 2 weeks using it I can't ride without it now. It's pricey, but it has its merit.

Please excuse my ignorance, although I have been riding for nearly 30 years, why do I need radar for my bike?

I got one of these about 6 months ago. I love it, but I wish I would have gotten the one with the light.

It warns you when cars are approaching from behind. It may not save your life, but it's really nice knowing when you need to move to the shoulder.

I use the radar+light version and it's been truly a game changer. I ride out by the countryside for the most part so less traffic on the roads. Prior to using this, I mostly stuck to the shoulders and not veer onto the main driving lane even if the roads were empty for fear of someone sneaking up in a car behind me. With this, you get both audio and visual cues for approaching vehicles from afar, and that truly adds a whole another level of awareness. Now I use the driving lane if it is empty knowing I can jump to the shoulder in a moment's notice with the radar. Plus the light starts blinking rapidly as vehicles get closer to your bike, adding another visual element for them to notice

I been riding for over 30 years. When I first read about it a few years ago. I thought it was a gimmick. I got one last year. it is a game-changer. It will alert you of anything approaching from behind before you can hear it. It can also tell how many objects are approaching. The one with light is better. It was for the same price last year,

Riding the shoulder, in general, is a bad idea. It is not just all the garbage that will cause flats, but it is dangerous as well.

Instead, take a lane. If there are 2 lanes I will take the slow lane and peddle hard so that I am doing at least 25 mph in, say, a 35 mph zone. If on a single lane, I will move over a bit, but still stay out of the shoulder.

I should mention that I used to ride for a living. I rely on my hearing to track cars coming up on me and a 6th sense developed over the years.

This unit would only benefit me if I lost my hearing.
