So I'm impressed. Is it a mountain bike you can hit sick doubles on? Prob not, is it a mt bike you can ride intermediate trails and commute through the city with ease? Absolutely.

Gravity is a factory brand bike out of tiawan one of the same factories brands like cannondale, diamondback and haro are manufactured. While with those brands they are shipped to an American distributor for final assembly, final assembly is putting on handle bars front tires and tuning.

Out of the box you get a full bike 85-90% assembled. With a little mechanical know how you can complete this. The only issues I had was tuning the breaks and tightening everything down. Other than that this thing has been a beast. I think I may need to adjust the shocks a bit but it is an option so it's doable.

EDIT: getting bike repaired by professional and will update based on how it rides when tuned
(Originally 1 star and original review below)

The bike is destroyed because of cheap components

First I realized it came with a different and older suspension format compared to what was in the picture, and that was the whole reason I bought that model. The spring attaches to the bottom tube at an off angle instead of the top tube. On the third ride of the bike with less than 50 miles total on it, a gear change on a flat, not under load, caused the chain and derailleur to go inside of the spokes and destroyed the whole drivetrain. This happened to other people and reviews I saw but I just assumed they set it up wrong. Everything was set up and tightened but the free wheel they used was a super cheapo - one that slips and skips all the time. Also the chain rings on the crank arm are cheaply welded together and non-replaceable. The headset is threadless and even if you tighten it up really heavily, the handlebars come off alignment from the fork and front wheel. They cheaped out on all the components you can't see easily in the pictures.
PROS: The full suspension is awesome as I've never ridden a full suspension before and I was able to take it on all sorts of crazy off-road trails.
Conclusion: Don't buy this unless you have the know-how and parts to replace the free wheel, the crank arm & front chain rings, and swap out the headset

The bike is decent but had some issues to start. Handles are comfortable, seat is good but I still use gel top seat cover I had from my previous bike. It's not the lightest but not the heaviest either, I don't think 30 lbs is too bad. I like the suspension for sure, hard to find a full suspension for a better price. I don't like the fact the water bottle holder is under the bike right near the tires, you'll literally be drinking dust. Im not sure I would've been able to get it together myself - thankfully my boyfriend knows a lot about putting together and tweaking bikes, because after it was together it didn't shift properly. I took the bike out for a ride and as I tried shifting down the thing just wouldn't cooperate. I was stuck in 5th gear the whole trip and ended up walking up the hills. I decided to try my sons bike (same kind, also new, and found his bike shifted right, so it was just an issue w/ mine) After that my Bf worked on it some more and finally it started to shift better, not perfect but definitely better. I was not impressed by the tires either, no grip, sissy tires don't work good on trails, need traction for stones. Honestly hoping for a flat tire just so I have a reason to get new ones, I've decided to just deal w/ them for now. Other than the shifting issue and the wimpy tires the bike isn't bad at all, especially for the price.

First off I gave this 4 stars instead of 5 because of the tires. Really? A full suspension mountain bike that comes with road tires? If you are planning to use this bike off-road which I am sure you are as why buy a mountain bike for the road...You will need to change the tires immediately as it is completely unrideable with the stock tires off-road. That said the rest of the bike is great and well worth the price. Yes it does require some setup and adjustment so if you can't do it yourself you probably shouldn't be buying bike online. However, any bike will need adjustments and tuning periodically so having to get professional help if needed is no different than with a bike originally purchased at a shop. Then again try to find a bike of this quality and equipment for this price at a shop. Other than the useless tires, I found the bike to be very good in all areas. The seat is comfortable, the shifters and derailleurs were smooth and worked great off road. The brakes are also very good as are the ergonomics. The bike feels good and definitely is robust and of high quality. I did not see any indication of the paint scratching easily as other reviewers have. The shocks are adequate and easily handled my 210 pounds but they do lack dampening so there is a lot of bounce, but what do you expect for the price. Still the suspension works well and makes the bike a lot of fun to ride over roots and rocks and can take the occasional small jumps. Again, other than the ridiculously useless tires this is a great bike. Too bad as if it just had cheapo off-road tires it would rate 5 stars!

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.
