Step up your training.

The Vector 3 Power Meter Pedals are totally redesigned from previous powermeter pedals we've seen from Garmin in the past. It still provides powerful data tracking at a relatively affordable, super easy to install, and bike interchangeable format, however, on the newer 3/3S versions, Garmin eliminates the pedal pods used on previous Vector pedals creating a more streamlined and low profile pedal that brings improved cornering clearance that you'll appreciate when diving in hard on that last turn of the state championship crit. The Vector 3 pedal looks and installs just like any other pedal but offers power analysis that will take your training to the next level. The Vector 3, that we have here, is a dual-sensing power meter for more accuracy while the more affordable 3S is a single-sensing model.

The Vector 3 measures wattage to an impressive accuracy of +/- 1% and cadence at the pedals, capturing power information as it transfers from the pedals into the crank arm. The sensor monitors tiny changes in the pedal spindle curve as force is applied to the pedals, and the data is transferred wirelessly via ANT+ or Bluetooth technology to a head unit or your phone. You can view your power during rides and download the data for extra analysis or for sending it to your coach once you get home. With the Garmin Vector 3's ability to measure power at each pedal, additional data features such as left/right balance and pedal efficiency dynamics are available.

The pedal itself features a lightweight composite body with a stainless steel wear plate to increase durability and provide a wide platform, allowing for free float and a large area to lay down the watts which you will now be able to monitor. The adjustable tension lets you customize the force required to twist the cleat out of the pedal and is compatible with Garmin Vector and Look Keo three-bolt cleats.

The pedals run on standard LR44/SR44 batteries located in the pedal for a claimed 120 hours of ride time. When the batteries are up, these pedals are easily user serviceable and with a quick trip to the pharmacy or grocery store you can replace them at home.

The Garmin Vector 3 Power Meter Pedals are easy to install and can quickly transfer between bikes, making it great when traveling or if you are renting or demoing a bike. Garmin includes a set or Vector cleats with six degrees of float. Please note that Garmin's suggested rider weight limit for this pedal system is 231lb.

What version of the vector3 are you selling? What firmware version?
What battery compartment version?

Not Reliable

  • Familiarity: I've put it through the wringer

First, I CAN NOT recommend these pedals as a finished product the right sensor does not really record data (read full review below).
I purchased the Garmin Vector 3 (both pedals) in May 2019. For the first 2 weeks everything was great. I ride 3-4 times a week, 30- 60 miles at a time. Connecting the powermeter is easy. Using the garminconnect app with the powermeter is great. After the second week I noticed the warning 'Right power sensor missing' would come up during my rides. I thought it was the batter, so I replaced the battery in the both pedal (very easy to do). The warning persisted. I did research online and found this was a known issue from the launch of the product. The design of the right battery compartment cause the right power sensor to loose connection. I contacting Garmin, free of charge they sent me a replacement battery housing for both pedals (easy to install). Then everything was fine for another 2 weeks, then back to 'right power sensor missing'. That is were I am now. I think there are other fixes that can remedy the problem, but the end user should have to 'DIY' finished products to make them work. I CAN NOT recommend these pedals as powermeters, the data capture is unreliable. I don't know how long the right sensor connection is missing before I get the warning. But I do have the Garmin Vector 2 pedals, and they are awesome. I can definitely recommend the Garmin Vector 2 pedals.

Do not buy these.

    I spent almost 1k for these pedals and after some months of use the issues started. It is clear that there are some design issues with the battery doors, bad engineering. Very surprising to see such issues from such a respectable brand like Garmin. Be smart, and avoid this frustrating pedals.

    Stay far far away.

    • Familiarity: I've put it through the wringer

    After one year, I have new battery doors, replaced PCBs (really?!) and had two additional replacement pairs fail. Garmin backed them up and worked with me, but it was a pain when you can’t count on them to work. After three pairs, I asked for a refund. Avoid like the plague.

    My experience

    • Familiarity: I've put it through the wringer

    I've had mine for about a year. I had a few dropouts in the beginning. I learned to oil the batteries (yes, that's a thing). Then they sent me the new battery housing, that likely comes standard nowadays, and I've had no problems. Replacing the batteries still involves baby oil, but they've been solid.

    Originally they were reading about 7-9% below my Wahoo Kickr, and after talking with Wahoo, I think they adjusted my Kickr downwards, as recently the pedals and Kickr read within 1 watt over a two-hour Zwift session. I don't know if they're accurate, but they are consistent and that's what matters to me for training.

    Works until first battery change

    • Familiarity: I've put it through the wringer

    I've had two pairs of Garmin Vector 3 (left and right power meters). I've tried all the service bulletins, including adding baby oil to the battery contacts every time I change them ... I can't make this up. Garmin has warranty replaced the battery doors, and again, the entire pedal set with the newer version. Still, the power drop outs/disconnects continue. It seems this is a design defect where the batteries still jiggle inside the pedal and causes power disconnects, especially from the right-to-left pedal Bluetooth bridge. You can solve this by permanently disabling the right pedal and use the left one on ANT+ only, but then you just paid $999 for a very heavy paperweight.

    Garmin refused to give me a refund, even after the second pair of warranty pedals kept disconnecting.

    I got the Assiomas and they are not only cheaper, but they are lighter, made better, look good, spin far more smoothly (the Garmin Vector 3 pedals spin like there is glue inside), and basically just work.

    Garmin Vector 3s

    • Familiarity: I've put it through the wringer

    First, I am not a pro. I am a high level recreational rider who loves data. I was an early adopter with a PowerTap hub over 10 years ago. I have since used SRAM Quarq(great), Stages(flawless but one-sided) and then a new generation PowerTap GS(great also). I purchased a new Kestrel R1100 with eTap in October 2018 which had a Quarq crank which was power meter compatible. After a lot of research I opted to go with Vector 3 pedals. There were so many concerns regarding battery life and water getting into battery compartment but I have been a long time Garmin fan(computers and lights) and I knew they would address problems which arise after release of a product. I have done 1 battery change in 4 months which was so easy. The data is very accurate when I compare to the PowerTap GS. I love the Cycling Dynamics which is really helpful to improve your pedaling stroke. I have never had an issue with pedals connecting to head unit. I love the ability to move pedals from bike to bike. There are cheaper options but I would highly recommend these pedals.

    Sensor issues and inconsistencies

      At first, these pedals worked well and I had no issues. However, after a few months i started having two major issues. 1. Right power sensor issue missing. The right power sensor would drop off and not read. 2. The more concerning issue is that my garmin head unti will stop reading power altogether and the power reading will simply not show up at all. #2 usually happens when I stop pedaling for a few seconds. For the price I do NOT recommend this product. Spend the extra money and buy an SRM or crank based power meter.

      I concur and have the same issues with pedals and Garmin 1030 connectivity. I spoke with Garmin this morning and they said there is a Gen 3 battery door that's supposed to fix this issue.

      Worked great--for about two months

      • Familiarity: I've put it through the wringer

      I bought the Vector 3 pedals because I've been so happy with the Vector 2 pedals I bought in 2016. Not so with the Vector 3.
      The Vector 3 pedals worked well on my Ultegra cranks for about 2 months, then I too started to get the "right power sensor missing" error message. I ordered a new battery cap from Garmin, but it's been only a slight improvement. The right power sensor still keeps dropping out, and I also get very brief power spike readings--sometimes up to 2000 watts, when I was only pushing 150-200 watts. One suggestion I've seen but haven't tried is to use 1 CR1/3N 3v battery instead of the two smaller, 1.5 v batteries that Garmin recommends. Maybe I'll try that next. But based on my experience so far, I don't recommend these pedals.

      Great when it works...

      • Familiarity: I've put it through the wringer

      I was one of the early adopters, having gone through the Vector 1 and upgrading the pods to the Vector 2's. Got the Vector 3's December of last year, and they had been working great. I was tracking power very closely to a Tacx Neo turbo.

      I had heard about the new battery doors in June and did request them, but did not install them since I was not experiencing any issues. Up until last month, I did start getting very low power readings along with a lot of power drops.

      So I ended up finally installing the new battery doors with two fresh pairs of LR44's. So far, the performance is back to when the unit was new. I also went though the procedure to verify the correct torque was applied to the axle, which was 1 Nm. Hopefully the new doors fix my battery issue, as I have been getting only around 80 hours of ride time from the Vector 3's.

      So if anyone is having trouble with your Vector 3's, be sure to:

      - replace batteries
      - replace battery doors with the new closed contact version
      - Check axle torque
      - Verify firmware is version 3.5

      It's a great product but still disappointing the end user is having to do this amount of service to a new device.

      Great Power Meter

      • Familiarity: I've put it through the wringer

      I have been using these petals on both the road, and in the velodrome and I have not experienced any power drop out problems. I am enjoying them so far!

      Garbage data, constant dropouts

      • Familiarity: I've put it through the wringer

      These pedals have been a tremendous source of increasing frustration while doing something I love. They do not work well at all with competing hardware like the iPhone, constantly suffer from single side dropouts (and also both sides), and really frustrate efforts to hold consistent power during interval training. It gets especially bad when you are trying to use these with training software like TrainerRoad to command the ERG mode on a Wahoo KICKR. Its really "fun" when your in the middle of a 10 minute over/under threshold interval on the trainer and the right side PM drops, and the resistance on the KICKR slowly ramps to try and get you back on target because the PM is only reading half power. As an endurance athlete obsessed with analyzing and using power data to get faster on the bike, these pedals have absolutely frustrated me and are no longer on the bike. I've stuck around for several months with these pedals, hoping Garmin would get the technical issues cleaned up with firmware updates--this strategy eventually worked with the Edge 820 computer, but not so much this time. If reliable data is what you want, I would highly recommend the Quarq PMs--I own 2 and they have been consistently reliable.

      I refuse to buy Garmin because they bring products to market with obvious software glitches and expect customers to wait for a firmware update fix.

      If I buy one gamin vector 3 now, it comes whit the new version for the battery cover or comes whit the old one?? Is because I saw a lot of bad comments about the product, but a read one article, that they fixed the battery problem.


      All of the Vector pedals that are shipping out from us and Garmin will be the pedals with the new cover and fixes to the issues others have had.

      Best Answer

      I had new doors shipped in Jun 18 and the problem still exists.

      I really wanted this to be great but..

      • Familiarity: I've put it through the wringer

      Bought these in January and it worked as it was supposed to for a couple of months but now it's useless. Either it takes 5-7 attempts before it calibrates or the power meter doesn't get picked up by my Garmin Edge 1000 or it drops the connection at least 50% of the time if it does get recognized by my Edge.

      Called Garmin demanding they send me a new pair and was told this is a known issue with many of their pedals and they traced the problem to a manufacturing defect with the battery compartment. They're expecting to have the issue resolved in about 1 month or so. If they can actually deliver on the fix, I'll be happy. If you've wanted a pedal based power meter and aren't in a rush to get some, wait to see what Garmin does with the fix.

      Hi Michel,

      Any update from Garmin on this? Hoping the issue has resolved, and despite negative reviews, wanting to give these a shot once it's been fixed.

      I received new battery compartment covers from Garmin a week ago to address the known issue they had with these pedals. I'm happy to say I've gone on 3 rides since and I'm now happy! The pedals calibrated on the 1st attempt at the start of each ride and I had power readings the entire time I rode. I think Garmin handled the issue with effectiveness and as such regained my loyalty.

      Heavy part-time power meter

      • Familiarity: I've used it several times

      These worked for about three rides before drop outs became progressively worse. Apparently this is a known issue and there are two fixes: option one fix your battery pickup at home with a piece of cardboard and some mineral oil, or option two, get a new battery compartment from Garmin. Given how beta these are I suspect the cardboard-oil version is more reliable. Also, cornering clearance on 172.5 is (pick your derogatory adjective) bad, and I suspect that the odd bump will ruin these for good. Maybe by the time they update to Vector 4 they’ll have the bugs worked out. Very disappointed as this seemed like a great solution.

      Totally useless pedal. Poorly designed

      • Familiarity: I've put it through the wringer

      I would not buy this pedal. As is typical of Garmin they release a product and let the public do the beta testing. My first pair of Vector 3 pedals I had to send back because the right battery compartment threads stripped and my second pair has nearly constant drop outs of the signal rendering them totally useless. Supposedly there is a software update coming to fix all of this. Such a bad company.


        I bought a set of Vector 3's and after spending a month with Garmin's support team helping them troubleshoot the issue, they narrowed it down to a defect in the battery compartment. Apparently lots of customers are having this issue. Rather than simply replace them, Garmin is shipping a new battery compartment and asking me to fix the pedals on their behalf. The only problem is that the repair kit is out of stock so i have to wait for them to get more.

        In summary, i paid $1000 for a defective product that Garmin now wants me to spend time fixing on their behalf, but only after they get enough stock to send the repair kit to me. Disappointed.

        What a bummer. Thanks for the cautionary story. I'm sorry to hear it for you.

        This kind of thing is so common with Garmin. I've seen too many cyclists having problems with their GPS computers, etc. It's frustrating.

        I've heard it before, Garmin doesn't sound like they care. That's why I usually go with other companies.

        I was considering these pedals but sounds like these too were too good to be true. I'll look for other power meters.

        Thank you for sharing your experience Colin. In two days looking for a powermeter, I have come across 3 negative comments about these pedals. I had issues with another garmin component and there was never a response from them. It seems I will definitely need to look for other option.

        Wow!!! I was about to order these, but it seems that I will hold off now. Nothing irritates me more than when I am getting a good PR going and I look down to find some piece of equipment is not sending data. I can blame myself for not charging batteries, etc, but such stuff just ruins the ride....and the next few when trying to troubleshoot the issue or make sure its not happening anymore.
