  • Fantastic bike for a kid!
Color: Black Size: 18-Inch Wheels/Switch
This is an all around great bike for my son. It looks “cool” and has all of the functions needed for a novice rider. I like how it has pedal breaks as well as handle breaks so the user can use the pedal breaks as a back up as they learn to use those on the handle. The wheels are wide enough to make for an easy ride. The only thing I’ll say negatively about the bike is that it’s tough to put together. The handle bar breaks were especially difficult to figure out. I had to call a friend over to help me and don’t think I could have figured it out without him. ... show more

  • Great bike at a great price!
Color: Black Size: 18-Inch Wheels/Switch
**Update from last review** We went head and ordered a 2nd exact same bike for our other son. This time we got a Amazon return (One at a discount). The bike had a few minor imperfections, slightly bent front wheel (2min fix w/ a spoke tool) and a bent right side crank bearing (Pretty simple and painless fix if you know how to repair it). Also did a rear tire coaster brake conversion to a freewheel since my son wanted a bike that could back pedal. Am I happy with both bikes, YES. Are my sons happy, YES. If I had to buy them both over again, YES I would buy them. ***First post*** Read lots of reviews and to be honest. Allot of folks should just buy a preassembled bike if they can’t read directions. Very strait forward and easy to put together. Make sure you have all the tools needed before starting on this, plan on it taking 20-40mins depending on your mechanical skill level. Does Not come with a kick stand! No problem, we pulled the adjustable one off my sons old bike that we got on Amazon for $5. I will be buying another one of these again for my other son when his B-Day comes around. If he behaves 😉 Absolutely yes a good buy! ... show more

  • The bike seems like good quality for the price
Color: Black Size: 18-Inch Wheels/Switch
I got this for my 6 year old for Christmas. I just finished assembling it. The bike seems like good quality for the price. It seems much nicer than anything that I found at Target or Walmart. The bike comes disassembled, but it goes together easily. The instructions were clear, and it took me 20-30 mins using a 10mm and 15mm box wrench and a 5mm and 6mm allen wrench. The only issue that I had was with one of the four bolts that tighten the handle bars. One of the holes was not threaded all the way through, and the bolt would not tighten. It was about a quarter of an inch off the seat. Fortunately I have a tap an die set, and I was able to thread the hole the rest of the way through. If you have the same issue, the bolt size is 8mm x 1.25. This added a few minutes, and was a minor inconvenience to me, but it might have been a bigger issue to somebody trying to assemble this bike at two in the morning on Christmas Eve. Overall I am happy with this purchase. I’m just glad I had a tap and die set. ... show more

  • Excellent bike for the price
Color: Black Size: 18-Inch Wheels/Switch
Reading some of the reviews I was expecting a pretty cheapie bike, but was pleasantly surprised. My son outgrew his old bike and I had a used on I planned on sanding down, painting and putting back together. When I priced out the materials, paint they were almost the price of this bike! Using up a weekend fixing it up made less sense than buying an entire new bike. Fast forward to receiving this, it was very well packaged and an absolute cinch to set up. I'm really surprised at the complaints of installation difficulty. It's not rocket science putting it together, and that's with not even reading the instructions. If you are even a tiny bit handy and have a socket set this shouldn't take you more than 10-20 minutes to put together. I added a push bar which immensely helps in pushing my son, who at times just doesn't have the muscle to make it up hills. Cranks and wheels turned smoothly and perfectly, brakes worked well, my son was very happy. The only suggestion I'd make is for Mongoose to include a cheapie bell, for what probably costs pennies at scale I think it would make kids happy. But no biggie, I'll just spend a few bucks and buy one. Overall a great bike for a kid, especially someone who you know will grow out of the bike in 2 or 3 years anyway. ... show more

  • Avoid Avoid.
Color: Black Size: 18-Inch Wheels/Switch
I was not pleased with this item. Had I not been very handy with bikes, this birthday gift would have been a failure. Note to self... buy things that need assembly well before they are needed. Had I had time, it would have gone back immediately. 1) The front forks were too narrow for the front tire, but I luckily had a clamp that i could use the spread the forks out enough to fit the tire. This is basic. I was lucky to have tools to overcome this severe obstacle. 2) The front brake was set at the factory to be too narrow to fit even the *rim* of the front tire. I was forced to pop out the cable to open the brake in order to fit in the tire. Because the brake cable was cut at the factory for a distance that was too narrow, I had to go purchase a replacement brake cable. Very irritating. The design of the caliper brakes did not allow for easy maintenance. 3) The bolt that holds the front brake in place is a poor design and the front brake gradually moves out of center and starts to rub on one side of the tire. If one tightens this, the brake cannot compress. 4) The threaded bolt that can be used to adjust the tension of of cable for the front brake where it comes out of the brake handle was badly bent and broken. (see attached picture) 5) The bolt holding the handlebar in place does not hold well enough even at the middle height of the handlebar. I could tighten it as hard as I could, but the 8 year old kid in the bike was easily able to move the handlebar out of alignment with the tire during leisurely riding, let alone the pounding riding that a kid's BMX bike is going to endure. 6) The reflector mounted on the seat post was not in alignment. It was 30 degrees off. This is easy enough to fix, but a simple visual inspection of this bike at the factory would have seen this. ... show more
