The Latest Costco Mountain Bike Deal is Essentially a 2018 Diamondback Hardtail?

Costco is known for many things, but not really bicycles… until recently. First, the wholesale giant started offering mountain bikes from the legendary Intense Cycles. Then Intense went straight to Costco for the launch of their new gravel bike. And while you may see poorly-assembled bikes on the storeroom floor with their forks on backwards, you may still find good bike deals at Costco.

Based on the link above, Costco has been selling select Diamondback models at least as far back as 2014, so if you wanted to just go pick up a new MTB while stocking up on your month’s worth of coffee or peanut butter, you can.

Currently, the latest budget Costoco mountain bike is a Diamondback Overdrive with 27.5″ wheels. This version of the Diamondback Overdrive 1 27.5 may be an exclusive that is only available through Costco, but it looks a lot like the 2018 Diamondback Overdrive 1, even the colors are the same. However, there are some graphic changes, and some major component differences that suggest this is a new model – though still very similar.

The Costco description of the bike says it has a Shimano drivetrain, like all of the other versions online… but it doesn’t.

All of the data I found for this bike listed a Shimano drivetrain, so it must have been just a “copy and paste” job for the Costco people who added this bike to their website. Instead, on this bike you’ll apparently find a MicroShift drivetrain with an LTWOO 8-speed cassette, KMC Z82 chain, and a Pro Wheel crank with a “steel cartridge” bottom bracket. That’s a miss when you compare it to the Trek Marlin 4 Gen 2 which is currently on sale for less, at $529.

Regardless, besides not having the stated Shimano drivetrain, the Costco version of this bike has a spec sheet that, frankly, isn’t much of a bargain for a lower price point bicycle. It also only appears to be available in the medium size. Note that according to the Diamondback website, the Overdrive is now only offered with 29″ wheels, while the Hatch offers 27.5″ wheels only for the size Small bikes, with the larger bikes also gaining 29″ wheels.

Costco’s price for the Overdrive 27.5 is $549 (shipping and handling included).

Surprised to see Ancient Lakes in Washington as the setting for those photos! There aren’t even a lot of folks here familiar with it.

It’s fine but Jesus Christ why do they equip newb bikes with triples? Are they actively trying to make people hate cycling?

I mean.. 3 chainrings for the price of one seems like a crazy Costco deal. Sign me up and include one of those roasted chickens in a coffin please.

Triples on a mountain bike are overkill (as are doubles, come to think of it), but the idea that they make people hate cycling is an exaggeration.

Mountainbikes had triple chainrings for decades, and people did just fine with them. I’ve gone to 1x on my ’94 MTB, so I am not a hardcore front derailleur fanatic, but the hate they get lately is exaggerated. They have pros and cons.

They shifted fine, even well, and in my experience tended to stay in adjustment. I recently rode a previous gen (m7000) and the shifting was lightning fast.
Their downfall is that they just weren’t that necessary. Also, my retro MTB has a front derailleur and I find that I often need to shift twice instead of once- gear 1-3 then 2-1. It is nice to be able to get one very big gear change with one shift, though.

These are bikes for people with almost no mechanical knowledge. If you think a person buying a bike at Costco is going to take the time to set up a triple front derailleur and make periodic adjustments you’re delusional.

Good points, I didn’t take the use case into account. But why the ‘tude?

I agree, most of these bikes will be ridden along black top trails, anybody that buys a bike from Costco won’t be necessarily be aware of the perils of a noisy front derailleur and chain jams when cross chaining. I’ve always thought it was misleading to claim a bike has 24 speeds when it’s 3×8. Still got my mid 90s cannondale in my basement, rode it many miles in its day and was fine with the 3 x8, but I had a bit more persistence than the casual user.

I have a hard line personal rule when it comes to where you get your bike from:
Never buy a bike from the same place you can buy tighty whiteys or cat litter. Period.

Hope this helps.

Namaste.
