The pictures are only the beginning it is now popping from the crank area and I haven't even ridden it an hour I weigh 240lbs at 6'2 this bike is not worth the money at all payments not payment it does not matter it's not worth the money The heads of the bolts were laying at the bottom of the Box Now I am 40 I've been putting bikes together pretty much all my life I'm not a pro but this thing is it's something else I'll tell you that If you would happen to buy this bike take it to a professional unless you know What you are doing all the ball bearings were dry except for the rear which barely had anything in it It needs packing grease right out the Box It's a true shame this is what mongoose has become cause back in my day it was a good bike/mountain bike I am emailing mongoose right now if they choose to do nothing I'm returning it because it's just not worth the money it may be a $150 dollar bike if that It has dense chips it looks like I've owned this bike for years and I pulled it out of the Box and wrote it for not even an hour it's it is what it is I guess Just beware make sure all your bolts are tight go over every screw not bolt on this thing because they're all loose And that's the end of my rant for now thanks for your time After about 2 more 100 bucks it Is now ready to go on the trail Inspect the bike very closely it was brought to my attention that the brakes are blue Mine are not it seems to be there's little differences from the pictures and what you get You can zoom in on the front or back wheel and look at the brake caliper brake caliper very disappointed will never buy again ... show more

    • Perfect for big and tall Men
At 6”7 300lbs I finally found a bike that we tall Men look normal on lol. Brakes are excellent only thing I can complain about was the break levers were opposite of where they should of been. Quick swap and good to go. Make sure to go over everything and tighten, a lot of things were only hand tight. ... show more

    • Great bike, bad instructions
No issues with the bik, but the owner's manual is terrible. They contain generic assembly instructions in the form of, "if your bike is of this type or has this feature, assemble like this." For someone who is new to bikes, that really socks especially since it isn't readily apparent which type the bike is. ... show more

    • Great Bike
Love this bike, it’s a replacement bike for one that I have had for some time. Really enjoy riding this bike very comfortable and handles well. Rides well with the 29” tires in the city streets. I would recommend this bike to anyone who is looking for a new bike

    • Just okay
I got my previous Mongoose Deception at Walmart 8 years ago. It was very similar to this model, including disc brakes. But some scum stole it from my carport and I needed to replace it. That bike, though heavy weight, was great. This bike came partially assembled. I had to spend close to $100 for a tune-up at the local bike shop. This bike needed shifting correction work, and disc brake adjustments. Plus, I did the pedal installation poorly in that I stripped both putting them on. I had to call the Mfg. and get two new pedals plus the crank. Luckily, they sent them free, under warranty which was cool. AND, finally, it came with a slow leak in the rear tire out of the box. I paid maybe $150 for the other bike back in 2012. This bike's price fluctuated here on Amazon due to the gouging that went on when the pandemic started. It was not worth the $343 I had to pay. Plus, it sat at the distributor's warehouse for over 2 weeks when I was promised 2-day shipping. Overall a bad purchasing experience and not a good value. And DO NOT ASSEMBLE this on your own. Go to your local pro bike shop! ... show more

    • Look for other bikes. Don’t buy this one.
If I could give zero stars, I would. We ordered a new one, it arrived today looking extremely used, tires were rough, there was hair (human I hope) anll over the bike, and entirely missing the pedals?? We returned it to UPS 30 minutes later. Perhaps look elsewhere for your bike needs.
