Stone Mountain Bike 20"/24"/26" for Men/Women/Girls/Boys

I live in Oregon where we're expecting a big quake, and I got this bike as a way to quickly retrieve my child from school after the quake when most of the roads are out. I was looking for a fairly inexpensive, but good, mountain bike I could keep in the garage. Google Gemini pointed me to several, and the price was right for this one. I picked the cheapest color, and I picked one that was "Used - Like New", and ordered it. I frankly expected it to be ugly, or super heavy, or generally cheap, but the opposite is true. I didn't really like how the black bike looks in the pictures, but it actually looks really good in person! It has a nice finish and an outdoor vibe - it looks cool! I assembled it and I'm still getting it all set up, but I actually LOVE this bike and I'm kind of excited about it now. I might actually ride it for other reasons - like to head into town, or just for fun, which I wasn't really expecting. I've had two other bikes as a grown-up, and I didn't like them as much as this one at all. I think this is a probably a good around-town bike for anyone who could encounter rugged terrain as part of their trip. It's probably not the right bike for people with more serious needs, although it could be set up like that - it's just there are probably lighter bikes out there, and ones with less nubby tires that would get better mileage if they're not needed. But for casual use, for post-emergency use, or to get a great bang for your buck, I would definitely recommend this bike.

I've had my Stone Mountain for nearly a year now, and I have been extremely pleased with the thing. The bike is simple and rugged; for me, it has been way more reliable than I expected. I've been using it for my daily commute, in hot sun, driving rain, and even some snow, and I've put something over 1000 miles on it. It has been a fantastic value for the price. Probably not the best choice for use on pavement (the rear tire has been worn flat, so I'll need to replace it soon), but a great starter bike for general use.

I really hate writing a bad review, I have a business and I understand when idiots want to rant about nonsense to get money back. That’s not why I am here. I am here because I just want to save others from going through what I went through. I almost always read reviews before I buy, but I didn’t on this one because I trusted the “Amazon’s Choice” label that’s put next to the rating. I figured I can’t go wrong. I don’t know pricing on bikes, and I take responsibility for that, if I knew that the price would lead to me saying “you get what you pay for” I would have bought a nicer bike, which, I’m going to have to end up doing now anyway. This bike is junk, it might as well be sitting in a dump somewhere. It’s garbage. I’ve ridden it maybe 4 times. Every single time I ride it (I’ve been trying to ride for about an hour to get a decent work out), every time I ride this bike the handle bar comes loose. The first time it came so loose it was just flopping around and almost falling off, I couldn’t believe it. I thought maybe I didn’t tighten it enough. So each time now before I ride, I have to tighten it as much as possible and every single time by the end of the hour it’s coming loose. Now on my last ride yesterday, not only was the handlebar coming loose, the left pedal is falling off. Keep in mind I’m not doing bike stunts or tricks, I’m not mountain biking on crazy trails. I am riding my bike around boston on flat easy to ride bike trails that aren’t strenuous. I am a novice rider who is barely even pushing the limits of the bike yet this piece of trash is falling apart right from under me as I ride it gently around bike trails in the city. It’s kind of a joke. Don’t waste your money, seriously. Spend a little more and get a real bike. Now I will have to do the same and just eat the loss because the return policy doesn’t let me return it anymore and I haven’t even had it a month. Enjoy the money you robbed me of, huffy, you’ll never get another dollar from me ever again.

My wife wanted a relatively light bike with hand brakes and several speeds for riding on a dirt track near our neighborhood. This was just what she needed. Not as light as the more expensive alloy or composite frames, but light enough. The gears shift by rotating a knob next to the hand grips so hands stay in contact with the handlebars. The bike came with a narrow, racing type seat; she liked the bike a lot better when we switched it for a more comfort seat. As others have noted, the bike came 90% assembled; all I had to do was put on the handlebars, the pedals, the seat and the front wheel. However, we had a problem with the pre-assembly. The brake handles stood straight up in the air rather than to the front so it was necessary to take hands off the handlebars and regrip to brake. The numbers on the gear shifts went underneath so they could not be seen. The gears were so tight my wife could not use half the gears. After I rotated the gear knobs and the brake handles 90 degrees forward, the brakes were safer and easier to use, the numbers for the gears were visible, and the gears shifted more easily. The bike comes with the basic tools required to assemble and adjust as required, but not the hex key allen wrench required to loosen and rotate the gear knobs. I had one that fit, or I could not have corrected the problem. Not sure I would want to pay full price for this bike, but it was a great deal when bought used.

broken some part

For someone that does casual biking, this thing is awesome. I got it on sale and it’s amazing on gravel and pavement, so far that’s all I’ve tried it on but it handles likes champ. I used to be a bike builder so putting it together was extremely straight-forward, although I put together two of these and both had the pieces for the seat clamp sprawled all over the bottom of the box; very lucky they stayed in the box even with being shipped all the way over to Hawaii. The seat isn’t that comfortable but that’s what to expect from a cheap bike, and you can always swap it out for whatever seat fits what you’ll use it for. Gearing needed to be adjusted just slightly, and works great even on bumpy terrain. I’m about 220 pounds so I tightened up the tail spring a good amount and it glides over bumps, fantastic deal.

EDIT 10/22 The seat broke. It keeps tilting back when I sit on it. I literally cannot tighten the nuts anymore. The seat is going to have to be replaced. Really pisses me off. This is a pretty good bike. I got this bike after spending years riding my mon's old Giant(which costs about $500 in today's money), and while it doesn't quite measure up to that one, it still feels pretty comfortable. It rides smoothly, and the gears are noticeably different from each other. I switch gears a lot when going against the wind or going up or down hill, so it was important the gears worked well. I brought it to a bike shop to put together instead of doing it myself to avoid any problems from poor assembly. Early on I had an issue with the right brake sticking, and I took it to the bike shop that put it together but it unstuck at that point and the bike shop couldn't see any problem. The brake hasn't stuck since, so it could just be that the bike needed breaking in. A bigger issue with the brakes is that they're simply too short. I can't comfortably rest my fingers on them when I'm riding (which you should always do to be safe). I can only really get one finger on them. The brakes are only half the size of the handle, and the inner part of the handle is taken up by the gear mechanism, so I can't put my hands any closer to the brakes without accidently changing the gears. Seeing as this is a women's bike, and women have smaller hands then men, this is strange. It's a minor issue though. Overall I'm really happy with this bike, especially considering I didn't have much of a choice since it seems there's a bike shortage because of the pandemic.

I’m a bigger guy (6’ 240lbs) and this bike has been great so far. I was worried it would fall apart after a few runs but it has held up great for well over 2 dozen rides. It took a bit to get the gears shifting properly but i have them dialed in now with no hesitation or skipping EVER which surprised me. 3 things I would recommend: First I bought a nice wide, soft seat which makes a huge difference as the stock one is like sitting on a skinny rock. Second I bought wider, longer hand grips. My hands were hanging off sides of the ones that came stock. Lastly, and what helped me enjoy this bike the most was upgraded metal spiked pedals. The stock ones are plastic and my feet were sliding off them constantly especially on wet days. Probably spent a total of 75 bucks on all the upgrades and it was well worth it. I’m not jumping off any cliffs or anything just cruising through the bumpy woods and this bike has been perfect for that.

Es una bicicleta ligera y a la vez de construcción robusta. Es ágil en su manejo y los componentes son de buena calidad.

Purchased a new bike for my grandson. Received April 9th - Assembled (Gift for Easter) Given to him April 17th - Bike is not usable. When riding over rough ground, seat pops up for no reason-unable to just adjust- has to be removed and corrected with wrench. Tried 3 chats to have this seat replaced and was offered a $20 discount and I can go out buy a replacement seat. WOW, where is warranty, where is customer service - asking me to disassemble this bike - rebox it and return it for a refund vs just replacing the defective part. This is not acceptable when making purchase of a new product.

Took about 30 mins to assemble. I did have to adjust the detailed screws a bit to get all gears to work but it was pretty easy to do. Overall my kid loves it. It’s quite light vs my other sons CCM bike of the same size.

Excelente bicicleta para niñas.

I have bought it a month ago. And today when I ride on the road, the handle is easily move which makes me fall on the ground. Luckily, I did not in dangerous , just bleeding a bit, but if people ride it in some bad environment or near a car. I can not believe what will happen
