Good spec for $299 shipped.
But only comes in medium, like most big box bikes, so if you're tall or short you're out of luck.

If you aren't average size, your best bet for a cheap mountain or urban bike is probably bikesdirect.
Same price:
https://www.bikesdirect.com/produ...-bikes.htm

Keep in mind that no "mountain bike" this cheap will have a fork you can trust for hard technical riding. These are for urban riding on bad streets, bumpy gravel roads, or at best slowly picking your way around rocks. If you want to really get into technical singletrack while keeping your collarbones and teeth, your price of entry is a lot closer to $1000 than $300.

Here's a quick way to tell the level of a "mountain bike" that's usually accurate:
If the front wheel is held on by hardware store bolts, the fork and bike are trash.
If the front wheel is held on by a quick release skewer, as the Northrock and BD are, it's a low-end rough urban/gravel road bike.
If the front wheel is held on by a 15mm thru-axle, it's a real mountain bike.
Here's another way to tell the level of a bike: check how many gears are on the rear and front cluster.

7-8 speed rear, 2-3 speed front: low end, not a real mountain bike
10 speed rear, 1 speed front: cheap real mountain bike
12 speed rear, 1 speed front: medium to high end real mountain bike

Modern mountain bikes have eliminated the front shifter by using more and wider gears in the rear. Any bike with a front derailleur is either a dedicated drop-bar road bike, or a cheap pseudo-mountain bike using obsolete parts to save money.
I bought this few weeks ago for an ebike conversion. There are YouTube videos for conversion of this specific bike, that influenced my choice as I knew that components would fit. I put ~5 miles before conversion and have added >250 miles post conversion.

Here is my rundown after having used it:
- This is a cross country (XC) bike not a true mountain bike, it does extremely well on gravel and green trails.
- The seat is very comfortable, it might not look like it but I have swapped it for a cushy Bikeroo seat and came back to it. I have comfortably done ~40 miles of gravel in one day.
- Front has 3 speed chainring. I didn't care for it pre-conversion. They should have just picked the middle one and stuck with it. Post conversion I have a single chainring up front.
- Disc brakes needed truing (which will happen on any bike out of the box), but the instructions said to just let them run and the noise will go away. Not accurate, you should true your brakes. Running them will wear off your pads and yes the noise will go away, but you don't want to wear out your pads.
- Rear-derailleur needed indexing. A few turns on the barrel adjuster, limit screws were fine. Yours might not need this. You just need to know how to notice this and how to fix it. It was not too bad out of the box, it was more important to me as I was converting it to an ebike.
- From what I can tell the rear has a freewheel not a cassette. This limits what gears I can run in the back.
- The frame is old style with the disc breaks mount behind the seat stays. You will need special disc brake compatible racks (if you want racks).
- Assembly was very easy. It was 90% assembled as it says. Few tune-ups here and there which would be needed on any bike not assembled and tuned by a bike shop. None of the tune-ups were mandatory.

I want to run these tubeless in future, but I am not sure if the tires are tubeless ready. They have Maxxis IKON which are supposed to be but I could not find the model number to confirm. They are likely cheap OEM Maxxis IKON. The rim is dual walled, I expect to be able to use tape on the rim to make them compatible. I will have to check if the channels for the tire bead form a good seal for tubeless.

My main use is paved and gravel bike paths, with some green trails. It fits those use cases. It has already survived a lot of miles and has not needed any components replaced yet.

Future plans are, when I am ready to upgrade I would rather sell this and get a different bike. I don't see a great upgrade path on this bike, but I knew that before buying it.


Edit: I had a flat and took off the tire to repair it. They have a wire bead (not foldable). Maxxis tire catalog does not list the wire bead IKONs as tubeless compatible, the foldable ones are listed as TR (tubeless ready). The part number from the mold imprint is 88R-002052, which searching online returns a different model. I will not be attempting to run these tubeless.

Same shit different day.

It's a COSTCO bike. COSTCO. Stop shitting all over it because it's not some prosumer bike at tens multiples of the price. It's sold at COSTCO for under $300. That should set your expectation level. Again, IT'S A $300 COSTCO BIKE.

That said, it's a great bike for puttering around. Looks good. It's not some pro end shit that you're tackling Everest with but that said it's not thousands of $$ either.

IT'S A $300 COSTCO BIKE.

For an in store purchase, is the bike fully assembled already?
Quote from shruiiken :
That would be a negative, unless it's the last display unit or something. They are in packed boxes identical to how they're shipped

"Assembled" is somewhat subjective. There is VERY LITTLE assembly here. Basically you put the wheels on, handlebar and pedals. Make some adjustments. Done.

This isn't like the old days anymore when you'd literally get a box of parts and have to assemble the entire damned thing. Mike take 20 minutes.

And then, after putting all the parts on, you need to adjust everything from the brakes and derailleurs to the hubs, bottom bracket, headset, and spokes and make sure that every bolt is properly torqued. Failure to do so correctly could result in a poor, possibly unsafe, riding experience and lead to higher repair costs in the future.

Going back and forth and reading some reviews and watching some Youtube videos, I ended up grabbing the Ozark Trail Ridge, my local store had the Large in stock for the normal $398 price.

It sounds like they are surprisingly better build quality than these Costco bikes aside from some usual suspects like grips and pedals, which I would replace on pretty much any bike in this price range. Gonna do an initial tune up fixing any assembly issues this weekend on it before taking it out for a test ride.

The fact that they had it in Large is why I pulled the trigger. Its for my wife who is 5'10" and Medium bikes are just a tad too small for her. Interestingly, the Walmart website said Large is 5'9" to 6'2" but when I picked it up, the hanger tag on the bike says 5'11" to 6'3". So we'll see, but I'm sure It will still be fine for her but they do have a Medium back at the store if we need to swap it out.

We'll see how it goes, Walmart has 90 day returns so should be plenty of time to figure out if its worth keeping.

Good choice that bike has a modern aggressive geometry with a better drive train and fork than this. Plus u can troll people with expensive bikes once u get good - "Got passed by an Ozark trail?!?"

I actually tuned it up and we took it out for a ride and decided to return it laugh out loud

Just to be clear, its not a bad bike for the price! It still feels like a Walmart bike though, and of course the assembly job was terrible, though I expected that. Anyway, aside from just an overall cheap feeling ride, it was slow as hell on the pavement, which again I certainly expected, but it was a real slug and the front fork was so soft with no lockout that made it even worse. She was riding a cheap Schwin bike previously and this one just didn't feel like the upgrade over it we were looking for.

Ended up going to a local bike shop and getting her a Trek Dual Sport 2, which is the same bike I have and she has really enjoyed riding from time to time. Granted, it was almost twice the price of the Ozark Trail, but it is what it is. We ride a mix of about 75% pavement 25% gentle dirt trails, so a full on MTB was overkill but the price was certainly right on the OT Ridge, so I gave it a shot. It would no doubt be a great bike for plenty of people, but we weren't feeling it.

After we picked up her DS2, I managed to find a Trek Precaliber 24" for $200 on FB Marketplace for my stepdaughter. Its basically brand new, the tires don't even look worn at all. The lady said they bought it in the spring for their son but then he got an ebike a couple months later. Her husband even gave it full cleaning and tune up before I picked it up, which was nice considering most bikes on there look like they never even had any cleaning let alone basic maintenance.

They're both really happy with their new bikes, so I'm happy!

Ah yeah the Ozark Trail has an aggressive geometry with the smaller range of a 1x and yeah that fork is actually a real mountain bike fork (albeit low-end but capable and better than the one on the Axum which I have). The DS2 has the range and yeah lower travel fork ideal for gravel bikes, good choice and lucky with that Precaliber!
