IGPSPORTSR30 Radar Bike Rear Light, 20H Battery Life, 150M Monitoring Distance, IPX7 Waterproof, Rechargeable Bicycle Cyle Back Tail Lights

Adding this SR30 tail light radar to an iGPSport computer is a few clicks on the settings menu. It shows up immediately and just works. I bike commute and my route includes a decent bit of road where mirrors help but eyes front is necessary for busy intersections and traffic lights. The beep tones from this radar are just what I need to discern if someone is coming up behind me to beat a light and bump me into the ditch. There's visual clues too but the beeping is really enough. The beeps are somewhat like handheld games from the 80s. They are easy to hear over traffic sounds and the patterns are such that they aren't akin to any other beeping thing on your kit. The volume isn't so low you can't hear but also not so loud that it gets to be obnoxious when you ride in traffic. I wear a Monster Boomerang on my neck so I can listen to tunes but still hear the demonic shouts, beeps and revved engines of angry motorists. If you wear earbuds you may not hear the electronic tones but that depends on your settings and computer.The radar is extremely sensitive. It really does pick up cars that are lanes over and can discern ones that make a more menacing approach. It seems to be able to tell large trucks from cars too.Installation is easy. Generic O-rings of various sizes keep the brace in place on your seat post. Future replacements are simple because O-rings are available at most hardware stores and online. Charging is USB-C so no special cables to label and misplace.The brake light is bright and it appears to go to sleep when there's no motion. That's important for me since I'm usually in a hurry when I get to work and I forget to turn off the tail light on my bike.Battery life is decent. I haven't had it long enough to incorporate into my charge routine at work but it's not yet died on me. The unit is fairly large and a bit heavy which is likely more about battery size than anything else. I'm happy with that compromise.For my review I'm using the iGPSport BSC300 -- it's currently the best low priced bike computer with high end features. The combination of the SR30 and BSC300 is an excellent way to level up a ride and not break the bank.

In summary, the iGPSPORT SR30 radar light is a very good product, although some minor issues could be improved. Therefore, I really like this product and will recommend it to people who want a good radar light at a reasonable price. More details are shown below:So far, I have ridden for 100 km with the SR30 radar light. It is my first time using a radar tail light, and the experience with the SR30 radar light has been great so far. The building quality of SR30 is very solid, and connecting it with an iGPSPORT computer (630) is very easy and fast (less than 2 min). Once you connect it, a small radar icon will appear on your bike computer's left side. The information from the radar will also show up clearly on the left side during the riding. When a car is in a dangerous distance, the computer will also make a sound to warn you. The radar is pretty accurate most of the time, although fraud warnings happen several times during my 100 km riding (less than 5%). The light is very bright and has multiple modes to shine. The battery life is very good based on what they claimed, although I have yet to have a chance to empty the battery so far. Therefore, it is a very good product and worth every dollar of the price.Pro:1. The quality of the product is solid.2. The radar is accurate, and the rate of the fraud warning is less than 5% in my 4-hour-country-side riding.3. The light is very bright and has multiple shining modes.4. The set-up is very easy.5. The battery life is good.Con:1. It may be tricky when you try to mount this light on your saddle bag since there are no specific components to mount it on it.2. The warning sounds from my iGPSPORT for a car in the back, navigation, and cadence are the same to me. It is hard for me to know the situation without looking at the screen.3. I did not see a place in my iGPSPORT PC where I could change the radar light's setting (light modes, etc.). There may be one, but I did not find it. And it may be worth putting it in a more obvious place.

I am an avid cyclist riding over 10,000km per year. I have been using radar on my road rides for about three years. So my review of the iGPSPORT SRTL SR30 radar unit is a direct comparison with what I currently use (photos included). This is a short review of using the two units simultaneously on a short 22km ride. I am a huge proponent of using radar–it’s well worth the cost.In summary, I'm impressed with the iGPSPORT radar. It's very easy to set up and use, and it's generally as good as, if not better, than other units I have used.The unit is lightweight, weighing less than 70g. I did not test the battery life yet, but when recharging it after using it for approximately one hour it actually indicated it was fully recharged after less than five minutes! It comes with two seatpost mounts (round and aero), three attachment bands, a charging cable, and a lanyard.The light has several modes including non-radar (solid, pulse,night, day, and peloton) in addition to the default radar mode. If you haven’t used radar before, it can “link” to either a head unit with Bluetooth (BLE 5.0) or ANT+ capability such as the iGPSPORT iGS360 Bike Computer (the unit I tested it with) or the iGPSPORT phone app.Here are some of the pros and cons of the bicycle radar unit:Pros:USB-C port for chargingIPX7 waterproofPicked up higher speed vehicles easily (i.e., “red” indicators)Easy to set up and useAccurate detection (especially fast moving vehicles)Loud alarm with multiple light optionsPicks up and displays multiple vehicles in a line behind youCons:Sometimes “loses” vehicles still behind you once they reduce speed (could be a function of the head unit, as it would sometimes happen with my other radar detector)Notice some light scratches on the light “lens” after one useComparing the unit to the one that I have been using, there are some slight differences to note:The unit picked up vehicles either at the same time or within 1-2 secondsOn approximately 30 percent of the detections, the unit “dropped” vehicles as they slowed to my speed, but picked them back up once they got closerPicked up faster moving vehicles and rated them “red” more accurately than my current unit, and switched oncoming vehicles to “red” status as they started to pass me at at higher rate of speedUSB-C (3.x) vs. USB 2.x

I'll mention up front that I ride a recumbent bike. Many accessory products are difficult to mount on some recumbents. My handlebar is under the seat, so it's not a satisfactory place to mount computers or headlights. I don't have a saddle or a seatpost, so the common taillight mounts don't work. I have a rack for panniers, and some lights are made to mount on racks.I have a iGS630 GPS Bike Computer. I expected the SR30 would be a nice addition. They paired (ANT+) easily, and the display support was already there. (If everyone's following the protocol standards, there shouldn't be any problems mixing computer and taillight brands.)The SR30's mounting options look good for a typical bike, but not for my recumbent. Since I don't have a seatpost, the seatpost mounts provided don't work. The basic handlebar mount that came with the iGS630 computer works for mounting the SR30 on my pannier rack. (I wasn't using the handlebar mount for the iGS630 because it's hard to see a computer mounted under the seat.) I'm going to try another mount that might work on the back of the seat. This would get the RADAR higher and make the taillight more visible. (And allow me to keep another nice taillight on the rack for redundancy.)The SR30 works fine. I'm already in the habit if checking my rear-view mirror frequently, so I am usually (90%-95%?) aware of cars/trucks/buses behind me before the SR30 alerts, but it occasionally alerts me to something I hadn't noticed.It has also alerted for cyclists overtaking me on trails -- if they're moving fast enough. (I think they have to be going at least 6mph or 10km/h faster than I am.) No alerts for cyclists who catch up with you slowly.I would like the alerts to be louder; sometimes they're not audible over traffic. (If there's traffic noise you're probably already checking your mirror. ☺) This is a shortcoming of the computer, not the taillight. The alerts would probably be fine as is if the computer were closer to my eyes and my ears. I have the computer (and the headlight) mounted out front, by my feet. Finding a way to mount the computer closer would also make it easier to read. When overtaking traffic is detected, I can see a red, yellow, or green stripe on the side of the display, with blobs moving up from bottom to top.But the alert volume and the display screen are not shortcomings of the SR30.I have seen the taillight flash to get the attention of overtaking traffic.I have not seen the light brighten for braking. I may have to mount it in front of me to confirm that feature. Or find someone to ride behind me to check for it.I've had 1 false alert (in 60 miles / 96 km). I was on an overpass, and the RADAR might have picked up traffic on the road crossing under me.I'd give the SR30 itself 5 stars, but the challenges mounting it and the computer ON MY BIKE make it less usable.

The radar is very handy when using on the public road. It detects cars behind the bike responsive and accurate. The light can be changed in different mode but I personally just stick with the daylight mode when riding. No problem connecting it to my bike computer (i have a igs630).
