Costco Infinity Boss Three Hybrid Bike


Costco sells the Infinity Boss Three Hybrid Bike for $219.99. Scroll down for photos. Costco has sold hybrid bikes like this the last several years. They just put them on the shelves again here a few weeks ago. This was located next to all the other workout equipment. This bike is a hybrid. It’s a little bit mountain bike & a little bit road bike. It would be great for getting around in the city. It’s smaller than a mountain bike so it can ride a little faster & it’s not built like a road bike so it’s a bit more comfortable. There are some people that really love this style of bike & especially for the price. It’s got a Shimano gear set & the frame is 700c x 18″. Here are a few more details about this Costco Infinity Boss Three Bike……

Infinity Boss Three Bike Costco


So I’ve read mixed reviews about this bike. Some people think it’s a great bike for starting out, while others think it would be bad. The argument is that it’s not a true road bike or mountain bike, so the user may have a bad experience. I’ve been on one of these bikes before & I think they’re great for what they are. I like to casually ride around the block with the kiddo’s & I want something comfortable. For a little over $200, this is really hard to beat. They don’t currently sell this on Costco.com so make sure to do your homework. The nice thing is you can always return it. There are some VERY HIGHLY rated hybrids on Amazon, so make sure to check those out here……

Price: $219.99, Item Number: 1389618

  1. I noticed these in our Toledo OH store in early 2019. I chose to think about it till I made my next monthly shopping trip (we live 30 mile away). Big mistake. On items like this, they only get enough to sell out quick, and don’t have them through the season. That way they don’t have any left at the end of the season. The next year I watched, and when they first came in I bought mine. When I came back four weeks later, they were gone, and never replenished, AND not available on website. So when you see one, buy it.

    1. That has happened to me so many times over the years! It still does. I think a product is not that popular, only to find it sold out the next time I go. I’m glad you were able to finally get your hands on one. They are sold out all around me & I’m not sure if they will be getting any more in stock. They have the “Women’s” model in stock right now, so we’ll see how quick they go. How did you end up liking yours?

  2. My local costco been out of stock for couple month now, I literally call them everyday to see if they back in stock yet, one guy told me it’s on order but anyone else that answers the phone says its not in stock and they dont know when it will be in, so I should keep on calling everyday to see if it arrived on the truck that day…so that’s exactly exactly what I do

    1. Good! Hopefully you end up finding one. I was just at Costco yesterday & they have the Women’s Infinity Boss Three Hybrid Bike. It didn’t look too much different from the men’s, so if that is something you would be interested in, be on the lookout. I’ll be putting up a post soon about it. Let me know if you end up finding one!

    1. This was in the Bay Area, CA. They have been sold out for a week or so now. Costco did just get the Northrock XC27 Mountain Bike, so if that is something you are interested in, make sure to check it out. I posted about it & the link can be found above.

        1. I was at Costco yesterday. The only bike I saw was the “Women’s” version. I’m not sure if you saw this or the regular hybrid bike because I couldn’t find the regular one anywhere. Only saw the women’s available. I was at the SSF Costco too FYI. Thanks for stopping by

  3. My local costco ran out of these bikes. But I found it in stock in another costco 33 miles away. Can the bike package be shipped in a car. will it fit in a car trunk?

    1. Depends on what type of car. I would be surprised if it could fit in a trunk. It would most likely have to be a full size sedan with a large trunk. If you are OK with it sticking out a bit, that may work too. These are very popular, so if you can borrow a truck or SUV, that may be your best option. Good luck & I hope you get one!

          1. Great to know! Thanks for that. The box is pretty big. I’m surprised it fit! Did you get it apart & assembled already? How do you like it?

        1. Hey SD,

          Just FYI, last night I bought one of these from my local Costco and it fits in my 2016 Civic just fine. (Folding down my rear seats so the box was put across the trunk & seats)

          1. Thanks Zihao! Glad you were able to get your hands on one. They are all sold out of the Costco’s near me in Northern California right now. Where did you purchase yours? Have you gotten a chance to ride it yet?

  4. My son has one still in the box. He’ll let it go for $350. He bought 2 and lives his bike. The other one is in the unopened box ready for sale.

    1. I’m glad he enjoys the bike & you were able to get one…….Now as far as your offer……maybe you could sell it to a local Costco Fan for the Costco price??? Consider it good karma for the future

      1. Maybe “Funny Guy” will give you a friendly Costco discount. I’ll keep update this post if I happen to come across any more

  5. Do not bikes on offerup! It’s well known in the bike industry that’s where bike thieves like to dump product.
    The Infinity is ok as a starter bike but nothing more. Also needs a tune-up with assembly as the bikes components are not adjusted/greased by the assembly factory. The tools supplied and what it says on the box as needed for assembly is far from the truth.

    1. Thanks for the comment Joe. I’m not huge into biking so that’s great to know about OfferUp. I’m in the Bay Area, CA & bike theft is huge. I’ll be sure to keep that in mind. Glad you think it’s OK as a starter bike, because I think that is what a lot of people use it for. As soon as my kid is able to ride a bike, I’ll probably get something like this just to putt around with him. Thanks for the comment

  6. I like these bikes. They are good to ride on trails and neighborhood.
    My friend just bought few from local Costco and he is selling those.

    1. Is he selling them for Costco price or up charging? There were a lot of people buying the fitness items from Costco and marking them up 100% on Craigslist. It’s unfortunate for the people looking to buy the product for personal use. Anyways, I’m glad you like your bike. Hopefully they come back in stock soon

    1. Not sure. I’m located in the Bay Area, CA & they are still sold out. Sounds like a few other Costco’s are getting them in stock, so fingers crossed. Let me know if you end up finding one

        1. Awesome! Thanks for the heads up. Glad you were able to get your hands on one! Please come back & let us know how you like it

    1. Nice! They have been sold out of my local Costco’s for a few weeks now. I’ve seen a few items back on the shelves, but no bikes. They must have been very popular, because I only saw them once. Did you end up getting one?

    1. I’m going to ballpark it and say 300 pounds. It depends on the tire & tube brands. You can always upgrade the tires and the tubes on Amazon, but I would give the bike a chance first. Hope that helps. Let me know if you end up buying it

  7. You can call your local Costco to see if they have it. If they don’t they can check the inventory of other stores nearby.

    1. As soon as I saw these in stock, they disappeared from the shelves. I have no idea if they will be getting this in stock again. This seemed to be a very popular bike, so hopefully they’ll get more in

  8. I purchase this bike from local Costco but there was a defect on it so I returned it and I wanted to get another one but they were out and I have been searching desperately to buy another one
    Where can I get this bike at I can’t find it anywhere online or in stores

    1. Sorry to hear. That’s always a bummer. I saw this bike only once, maybe twice & then it was gone. Hopefully they get more in stock soon!

  9. I’d like too know if there’s anyway of purchasing this boss.three Schimano infinity bike. Or are you going too be sending any more of these bikes to the Costco stores anytime soon.

    1. As soon as I saw these bikes at Costco, they were gone. I’m not sure if Costco will be getting another shipment in. I’ll keep my eye out at my local Costco’s too see if any are in stock. Hope you end up finding one
