My Bike Radar Traffic


See how many vehicles passed you in a ride. Plus upload your .FIT file after the ride to see exactly where each car passed you. The latest version doesn't require internet access. I am hoping to add an automatic sync feature at some point in the future, but for now you must manually upload your ride to if you want to see the locations and speed data for where cars passed you.

What’s New

2.2.1 - Restored compatibility with 130 plus and 1030 plus devices.</p><p>2.2.0 - New version attempts to display larger fonts and should resize to fit as the count gets larger. For those with the app already installed, you may need to go back into Garmin Express or Connect Mobile to choose the fields you want displayed after updating to latest version. </p><p>2.1.0 - A few bug fixes, plus ability to choose up to 4 fields to display - Total vehicle count, Lap vehicle count (for on-the-bike assessments of how busy a particular road is), Relative approach speed, and Absolute approach speed. The speeds are displayed in the units that your device is set to ... but NOT if you change while the device is on. You have to power off and back on if you change units to see the speed in the new units (metric vs statute)</p>

Absolutely amazing app, a must-have if you are commuting, it really does work quite well. Can you make it work to display car speed when the bike is stopped at 0 Speed?

March 7, 2021 | Version 2.2.1

Great idea !, Thanks Would it be possible to separate the monitored data into 3 independent fields in a future version? I mean, Vehicle count in one field, realative velocity into another field and absolute velocity in a 3rd field ? That way the users can display the fields in different screens, the fonts can be larger. One more thing, can you measure the distance from the vehicles? If so, can you change each circle that show on the screen representing a vehicle approaching the bike by the estimated distance to the bike ? This would be great in Edge units with larger screeens, specially 1030 and 1030+.

February 27, 2021 | Version 2.2.1

Works perfectly and gives more information than standard system. I find it very helpful to see the speed of the vehicle approaching you from behind.

Well done to the developer - great idea, well executed, particularly since the speed fields added. For SportTracks (mobi) users, the data is available on their charts, and is excellent. Looked for a way to donate, will do that when one becomes available.

I recently updated the website to support drag/drop upload and managed to break the import feature without realizing it. So sorry about that, but I believe I have it fixed now. Please try to upload your ride again and let me know using the "contact developer" link if you are still having problems. Thanks, Brian Toone

Thanks for this addon it is a must having varia radar! I have only issue with speed of cars. I'm using metric units and the speed (relative and absolute) looks significantly greater then I would estimate. I tried to check it under a street radar, but it doesn't show the speed in the data field when you stop. It looks the speed in km/h is about 1.5-1.6x higher then reality, but I have no chance to verify it. It could be a unit mix-up km .vs. mile... Thanks, Milos

Brilliant addition to my Edge+Varia setup!

Very good data field. The font is too small when selecting two data. And with four, it's completely a miniature. I am asking for a larger font

Developer Reply
August 17, 2020, MyBikeRadarTraffic

Thanks for the feedback. I agree that the font is too small, but the problem I've run into is if you ride on busy roads with hundreds of cars, the numbers from each field run into each other with a larger font. I'm working on an update that will dynamically resize the font today, so please give that a try once it is released and let me know if this helps.

August 11, 2020 | Version 2.1.0

Hello MyBikeRadarTraffic, thanks for the great datafield. I often turn off the light at daylight with another datafield. Would it be possible, to turn on the light, when a car approaches faster than 50kmh or a self specified speed? And if the car passed, turn off the light again?

Developer Reply
August 11, 2020, MyBikeRadarTraffic

Yes, this should be possible. I will look into adding this feature soon. It won't be activated by default, it will only be something you can enable via settings when you specify a speed at which you want the light to come on.

A must-have add-on for the Varia radar.

July 21, 2020 | Version 2.1.0

Really like the app but have to uninstall after notice varia battery life diminished. Cannot find way to uninstall though. Help please.

Developer Reply
August 11, 2020, MyBikeRadarTraffic

Easiest way to uninstall is through the Connect mobile app or through Garmin Express. Both have the ability to show you what apps you have installed with an uninstall option. Also, note that it should have no impact on the Garmin Varia battery life at all. The only way that you would see a decrease in battery life is if prior to using my app, you used to run the Varia by itself without having it paired to a Garmin display device such as the Edge series or Fenix series of watches. If that is the case, then yes, the process of pairing it and keeping it paired with the Garmin device does decrease battery. I think this would be an unusual situation though as most people like to have it paired with some sort of display device so that they can receive notice of approaching cars. For those people, there should be no decrease in battery life.

July 13, 2020 | Version 2.1.0

I love this! I actually find this very useful. When I ride out in the country it's interesting to see how fast cars and trucks are going when they pass me on those narrow roads. Keep up the great work!

July 1, 2020 | Version 2.1.0

Brilliant addition to the Varia Radar experience. A must-have install for all my Garmin units.

Version 2 This App just keeps getting better. It is the one app I use all the time as a road/commuter cyclist. Having data now included in Garmin Connect is really useful. However, the web site gives you even more data to look at.

Almer Aantjes
June 14, 2020 | Version 2.0.0

Great job so far. Is it possible to make one datafield of approach speed? Now the numbers are verry small because it’s combined with vehiclecount. It would be so cool if we would have a datafield of the vehiclespeed. It’s just a calculation of riderspeed + approachspeed. Maybe i think to simple -:). Greeting from the Netherlands

Developer Reply
June 14, 2020, MyBikeRadarTraffic

This new version allows you to do that, but you have to go into Settings for the IQ app in Garmin Express or Garmin Connect Mobile, and select the Approach Speed as the only field visible. It will still count all the cars and record that information for post ride analysis even if the only item showing is approach speed.

Great app for the Edge. I use my Varia radar daily and I being a data "geek" I love that I can see the cars that pass me and the speed data. It helps me plan routes or rides depending on traffic flows are certain times of the day. If you have ever wanted to know more about your radar data this is absolutely the app to have. I have to give credit to GPLama and his video for pointing me to this app. If you want some more information on the app check out his review on Youtube.

May 27, 2020 | Version 1.3.4

Brilliant idea! Speed of vehicles reported seems off. Being passed by cars going 60+ mph but map shows them way slower... If this could show approaching speed of vehicles I'd part with good money for it! Please continue to develop this....

Developer Reply
May 27, 2020, MyBikeRadarTraffic

Thanks for the review and feedback. One note about the approach speeds - the speed labeled "radar speed" is a relative speed to your speed, so the raw speed of the vehicle would be the rider speed added to the radar speed. Both of my Varia radars are older ones, but they definitely seem to report speeds that are higher than what I perceive as the passing speeds (the opposite of what you are seeing). So I wonder if there is some quality control with the accuracy of each Varia about the speeds it is measuring. Some devices tend to be fast, some devices tend to be slow. I may eventually put a survey on the mybiketraffic website to see how many users perceive the reported speeds as too slow, too fast, or just right. There's not much I can do on the website itself but report the speed that the radar is measuring unless I wanted to add a "calibration" feature that would automatically add/subtract from the reported speeds a calibration value based on each individual user. One way to do that would be to have a user stand next to a professional radar with their varia and compare the difference between the professional radar and the varia radar. The next version of the app which will show you the vehicle speeds would help enable this calibration process.

Works great on my Edge 530 to show total count, and uploads nicely to Garmin connect to show vehicle count over time or distance, but when I try to import the .fit file to the developers site to see where on the map I encountered cars, I get an error saying that the .fit file doesn't contain any radar data. I emailed the developer and awaiting a reply.

Here's the reply I sent to you (but Garmin somehow had the wrong email address associated with your account, so I got a very interesting reply from a different Garmin user who had never heard of my app and had asked a question about a different app) - In any case, I think you should email me directly at [email protected] instead of using the Contact Developer link. Can you send me the ride file so I can see what might be causing the problem? Again, send it directly to me at [email protected], Brian

When i import the garminfile this message (the following errors occurred: did not have any radar info. ) show up. I have been out twice now and i get the same message. Maybe i miss some information or did it not work with a ipad. I have all the updates and the datafield seems to worg on my edge 1030 /Kent

A few notes - you have to make sure to add the Connect IQ Vehicle Count data field to one of your data screens. It isn't enough to just install the app, you also have to add the data field on one of the screens. This is what triggers the recording process. Also, I'm not sure if it's a typo or not, but you have to upload a FIT file ... not a ZIP file. Are you selecting it from the Activities folder on your Garmin? I'm working on getting it setup where it will auto-sync from your Garmin Connect account so that it will automatically import onto the mybiketraffic website without the extra steps. Click the Contact Developer link under additional information if you still can't get it to work, and I'd be happy to help find out what's wrong. Thanks!

Sorry, no statistics available yet.
