I’ve already reviewed iGPSport SR30 a 12 months in the past. Initially, it carried out decently, however after one firmware replace, it began giving too many false positives, so it grew to become unusable. Naturally, I used to be curious concerning the newer SR mini radar. Has iGPSport solved the accuracy? I’ve been utilizing it for a number of weeks and have additionally in contrast it to different widespread biking radars to seek out out.
Full disclosure: I acquired this radar from iGPSport for testing, however as at all times, I assured them that I’d reveal the nice, the dangerous, and the ugly. They don’t have any editorial enter or management over the ultimate article.
KEY TAKEAWAY
iGPSport SR mini shocked me by giving me virtually no false positives (I recall getting about 3 all through about 20 hours of utilizing the radar). It’s virtually on the identical stage because the Varia or Wahoo radars by way of accuracy. Sadly, the true battery life is much shorter than the claimed one, and the field doesn’t embrace a seatpost mount. Proceed studying for extra particulars, or purchase iGPSport SR mini right here.

The field doesn’t embrace normal contents we’re used to. As an alternative of a seatpost mount, it features a saddle mount. This might be an issue in case you are not prepared to surrender in your saddlebag. Fortunately, I had a mount from the SR30, so I may take a look at SR mini with that mount, which sucks, btw., as a result of it slides on the seatpost.


I first used the SR with the Wahoo ELEMNT ROAM 3. SR mini shocked me because it didn’t give me too many false positives. In truth, it gave me round one false optimistic per 3 hours of driving. I used to be shocked as a result of the SR30 was a multitude. After one firmware replace, it began giving me a number of false updates per hour of driving. It grew to become unusable.
Naturally, I used to be inquisitive about its efficiency in comparison with Garmin Varia RTL515, which is my benchmark radar. So, I paired RTL515 with my Garmin Edge 840 for side-by-side comparisons. In concept, SR mini ought to detect vehicles quicker, because it has a 20m longer detection distance (160m). Nevertheless, each radars detect autos about the identical time, and typically, SR mini detects them later, by no means sooner. The identical occurred to me with the SR30. The claims didn’t meet the truth.



The SR additionally carried out nicely in detecting a number of vehicles without delay. It was in a position to monitor them precisely, particularly in bends when a number of vehicles had been driving behind me and the radar may “see” them (in contrast to when vehicles are driving behind one another). I replicated this by pointing the radar at a freeway with an 80 km/h (50 mph) velocity restrict. SR may detect vehicles nicely.

The variety of false positives was near zero. Throughout one cost of the radar, I bought one or two. That is so refreshing as a result of radars, such because the Magicshine R300 or iGPSport SR30, give a number of false positives per hour. The Cycplus L7 I reviewed lately gave me between 3 and 5 false positives per hour, relying on the realm. For instance, in city areas, false positives are extra frequent than in rural areas.
The battery is meant to last as long as 11 hours within the day flash mode. Throughout the first spherical of testing, the radar lasted me 8.5 hours. This outcome upset me a bit, however a lot of the radars I examined didn’t attain the claimed values for a number of hours. The next chart reveals the battery lifetime of among the hottest biking radars.
I additionally seen that the Auto Sleep characteristic didn’t activate itself throughout my first lengthy trip. I don’t know why, as a result of I had turned it on earlier than the trip. Throughout my second trip, it labored. This can be a helpful characteristic, by the best way. The app additionally means that you can regulate the period after which the radar falls asleep.
SR’s brightness is common. The flash has increased brightness, so I favor utilizing it as an alternative of the stable mode. The next image (credit score to the GP Lama for the thought) compares the Bryton Gardia R300L, Varia RTL515, and SR mini. It’s not as clear within the image, however the Varia had the brightest and most centered mild, whereas the SR was the least shiny.

I’m glad that the radar remembers the final used mode and modifications the flashing sample all through the whole overtaking interval. Nevertheless, you will need to allow this characteristic within the app. It needs to be on by default! Naturally, you may as well management the SR’s mild modes from the top unit if the top unit gives this performance. Sadly, Wahoo (or another bike laptop) can not get up SR from standby mode; they will solely flip it off if you flip off the exercise. That is one other massive disappointment, and I hope Wahoo will implement this with future firmware updates.
You’ll be able to barely regulate the customized mild mode, however the remainder of the sunshine modes needs to be adequate. The app additionally means that you can activate and off some extra settings, mild modes, and it will probably substitute a motorcycle laptop by exhibiting you vehicles like another radars (Varia, Gardia, and many others.).





One other factor I wish to talk about is the mount. It’s a disgrace the seatpost mount is just not included, as a result of the saddle mount, whereas being agency and stable, won’t suit your saddle rails and can almost certainly stop you from utilizing some saddle baggage. So, then it’s important to depend on third social gathering mounts. However let’s be sincere, these are normally significantly better than the first social gathering mounts that have a tendency to slip on the seatpost (honouring exceptions such because the Cycplus L7 mount).
Keep in mind, although, that the iGPSport SR mini socket is incompatible with the Garmin quarter-turn mount. It’s rotated by 90°.

Issues to Contemplate Earlier than Shopping for a Bicycle Radar
Biking radars need to be extremely dependable. They might offer you false positives, however they need to by no means offer you false negatives, that means they by no means miss a automobile.
You need to have zero tolerance for false negatives for those who purchase a tool like a biking radar. Nevertheless, you shouldn’t rely totally on a bicycle radar and use your different senses whereas driving.
Primarily based on my testing, the SR proved dependable by way of its technical specs. It detected vehicles about as rapidly as Varia and didn’t miss any vehicles. The variety of false positives was near zero.
My Verdict
The principle promoting factors of this radar needs to be the low weight and worth. It ticks the packing containers there. However what about its core characteristic, which is the automobile detection? The radar does a very good job there as nicely, because it doesn’t give many false positives. Their quantity is decrease than different Chinese language radar options, averaging about 2 per cost. It may well additionally monitor a number of autos without delay fairly nicely.
It’s a disgrace that the field doesn’t embrace a seatpost mount, and that the precise battery life falls beneath the common in comparison with different biking radars, so you’ll need to recharge it regularly.
It truthfully surprises me that the earlier radar from iGPSport, the SR30, performs so poorly in comparison with this one. Nevertheless, I’m glad that they improved the algorithm, and the SR mini is now virtually on par with the highest radars, such because the Wahoo TRACKR Radar or Garmin Varia.
