This bike is exactly as advertised. Some really good components on a decent frame for a great price. I am a middle age man, with moderate, chronic physical conditions working on getting back in shape. Mountain biking was something I used to enjoy so I wanted an entry level bike to see how it works for me before investing serious money. Assembly really was not too bad with a little patience and some previous knowledge. Gears were perfectly adjusted and I did some minor tweaking to the brakes. I immediately replaced the seat. It was terribly hard. I bought one from Bikeroo and was extremely pleased. I will be purchasing new tires before very long. The included tires are fine, but I want more traction and durability. The forks, shocks, brakes, gears, and frame all seem fantastic for this price! I have put about 75 miles on the bike at this point. I recommend this if you are a beginner to get a feel for the sport prior to investing serious money or if you are a casual mountain biker.

Great bike! I'll start with more general info and then move into the details. I got the small 17 inch bike in yellow. Ordering was easy with no hassle. I live in New Mexico and the bike shipped from Dallas, so it took only 3 business days for it to arrive. It arrived in a large box, about 80% assembled. Assembly does not require a professional, but involves installing the front brake, front wheel, handlebars (just make sure they're tight), and the saddle. The tires come pretty low on air, and should be replaced, because they go flat within an hour of riding. Suspension: front suspension is great. Easily adjustable, great shock absorption when downhilling. Rear shock is a bit slow but is just fine on jumps. Brakes: mechanical disk brakes provide great stopping power, nice and quiet.

Edit: the extra j-shaped part is a sacrificial part that is meant to be destroyed in case of an accident to protect the rest of the bike, which is why they provided an extra one. Original review: The instructions that come with the bike are total garbage. It pretty much just tells you to take the bike to a shop, go slow, ask questions, use grease (I didn't), and use muscle (what?). There are no step by step instructions and no tools provided. I'm pretty handy and did eventually get it working well. Getting the handlebars, seat, front disk brakes, and front wheel "on" is pretty self explanatory, however pretty much nothing was lined up correctly (even stuff installed at the factory). If you don't have that front brake lined up perfectly, it sounds aweful when riding and it's pretty finicky about placement. I also had to adjust the back brake position. The derailleurs needed to be tuned (thanks internet) so that it would shift properly and quietly, but it's pretty quiet now. In the end, I still have an extra piece. It's a J-shaped piece of metal with some holes in it. There's already an identical piece like this installed on the back of the bike and it does not fit on the front. The bike seems to work fine without it, so maybe it's a random spare? It seems like a sturdy part that wouldn't likely ever break, so I'm not sure why a spare would be needed when they don't provide spares of anything else. Makes me worried something important is missing and the bike is going to fall apart on me, but it seems to work ok. (Edit: after some research, this part is called a derailleur hanger which is designed to be damaged in an accident to save other parts, hence the spare). Again, actual assembly instructions would be very helpful. A signature was required so USPS double-rang my doorbell and woke my toddler from his nap, which is annoying since this is a pretty cheap bike and I've had much more expensive things delivered with no signature required. I think my least favorite thing about the bike is that I don't see how you could ever attach a kick stand to it with the way the back is designed. So I'll have to lay it down or lean it against something. Overall, this seems like a good bike for the money. Putting it together was a pain, and honestly if I could rewind time, I would just spend a little more and go to a bike shop or even a sporting goods store to get a bike that's already put together and tuned properly. My 2 year-old kid was going nuts while I was putting it together and couldn't wait to go for a ride with dad, and kept trying to "help," which was cute, but...not actually helpful. I'd rather just have pulled a new bike out of my trunk, thrown his seat and handle bar attachments on and taken him for a ride. If you're on a budget, though, and don't mind tinkering and watching a YouTube video to compensate for the lack of provided instructions, and don't want a kick stand, this is a decent purchase.

Excellent entry level mountain bike. I am an experienced mountain biker coming back from a 5 year layoff due to injury. Gave away all my bikes so I needed something inexpensive to see if I was going to be able to ride again sustainably. This bike has all the components of a bike costing thousands more - it’s just 10 to 15 lbs heavier because it doesn’t utilize state of the art materials such as carbon fiber, titanium or high strength aluminum. Great disk brakes and 24 speed shift set and good full suspension ride. Comes well packaged for shipping and is very easy to complete final assembly for the average do-it-yourself person. Excellent choice for any biker on a budget.

I bought this bike for my girlfriend and she Loves It. It shifts easily with the thumb shifters, and the shifters have indicators that let her know what gear she's in. The mechanical disc brakes are a little noisy but work fine, and seem to be better than cantilever or caliper brakes on wet conditions. The bike arrived mostly assembled and in good shape, and assembly was pretty easy and straightforward. The gears shifted alright out-of-the-box but needed to be tuned first, and the brakes were already adjusted and ready to go. We needed to adjust the spring shock since she is small, and the ride was a little bit rough for her light weight before the adjustment was made. The fork shocks don't seem to be adjustable, but they work fine as-is. Trail riding is fun on this bike, the shocks really soak up the bumps on rough terrain, and the rear shock keeps the back tire on the ground when going up a hill with loose gravel on it. Plenty of gears keep a rider up with the rest of the pack, as well as offer plenty of power when going over hills and rough terrain. The lightweight aluminum frame makes it easy to take it on and off the bike rack, and is light enough for my girlfriend to control and sling it around on complex rides. It's just an overall fun bike to ride.

Great bike, smooth ride, and gear shifters. Worth the price. Front wheel was damaged during shipping but the company was quick to respond and help correct the issue and sent a replacement part for the wheel.

Well, it’s been a week since I got the bike, so I decided to write my review now. The bike came in half assembled so it didn’t take me too long to put it all together, I only had to do some minor adjustments and add air to the tires, with that I was out of the house giving it the first try, went around the block and was quite pleased with the handling and overall feel of the bike. Since then I added a handlebar riser to make it easier on my back, changed the factory seat for a comfort one and installed a bike computer that I had on my previous bike, that’s about all I have done to get it where I wanted it. I have put about 40 miles on it since then and I am very impressed with how quiet and smooth this bike is, my previous bike was a Genesis Max air 29”, which was pretty good for a Wal-Mart bike but didn’t have rear suspension and it was taking a toll on my back and butt. The Gravity certainly earns its name when it comes to lessen gravity’s effects, the rear suspension does it job. Same goes for the dual disc brakes, very effective. I have gotten a few stares while street riding, I am not sure if it is the cool bright yellow looks of the bike or the fat guy riding it, but I am happy either way. I have read some folks complaining about the tires not being big enough for dirt but so far, I have not had any issues with them, half of my riding is done on rough terrain and they have performed well so far. As far as cons I only have one, the position of the water bottle holes, I installed a holder and used it once, the amount of mud I got on the bottle made it not very appealing to drink from, however, looking at the frame of the bike I can’t think of any other place they could have to put it so I guess it’s fine. Again, overall, I am very happy with the bike and I hope it stays as it is for a long time.

This bike was purchased for my teenage son. Having had it now for a week, and with us both having ridden it several times, my rating would be somewhere between 3 and 4 stars, but I just cannot get to a 4. Here are my initial thoughts, broken into the good and the bad: good: - frame and component quality (including shocks) good for price. I'd say to do better than this, you'd likely need to shell out at least a couple hundred dollars more; - it's a really good looking bike; - assembly was quick and easy - required only attaching seat, handlebars and pedals, and putting the wheels on (15 mins); - quick delivery (5 or 6 days), and packing was good; - seller quickly addressed a defect I discovered when assembling bike (warped rear brake caliper). My email was immediately acknowledged, and a replacement caliper received 3 days later. bad: - disc brake stopping power is disappointingly weak (esp rear brake). I know everyone thinks disc brakes are cool, and I know first-hand that higher quality disc brakes are superior to rim brakes, but I'd much prefer the rim brakes if this is the stopping power you have to live with at this component level. May simply need adjustment or repair, but I do not know how to work on complicated disc brakes, so I'll need to pay to take to shop. - shifter/derailer clearly not calibrated (esp gear set at crank). Gear shifts are not dialed in, and many upshifts do not catch. Again, I do not know how to work on these complex components, so again, I'll have to pay a shop. - if bike weight is a big issue for you (it's really not for us), this bike is by no means light. - the owners guide / assembly instructions were a joke. Please, for love of god, include a readable step by step assembly and trouble-shooting guide (for this particular bike!) which might include at least some mention of brake and derailer adjustments, as well as how to connect the brake cable to brake lever mechanism. These pre-assembled bikes really need to work perfectly right out of the box. No customer should immediately be saddled with a $100 bike shop bill to make calibrations/repairs to brand new components. There needs to be better quality control, and perhaps someone who actually tests the brakes and gears before shipping. Such a check would have also revealed my bent caliper, as I highly doubt such a strong piece of metal was bent in shipping. So my recommendation is this: if you know how to work on shifter/derailer/disc brake components, you’ll likely be able to get this bike in good riding condition and will be very happy with the good deal you’ve gotten. Otherwise, if your experience is like mine, you’re going to have to spend some money/time right off the bat just to get this bike in the condition you'd expect a brand new $400 bike to be in when received.
