Awesome bike!

[This review was collected as part of a promotion.] Beautiful looking bike! Super cool with the pegs for stunts. My nephew is into BMX bikes and I can’t wait for him to have this! Super easy to put together. Things needed for assembly are: 5&6mm Allen wrenches, 14&15mm wrenches, Phillips screw drivers and scissors. The seat is sturdy yet comfortable. Tires are beefy and perfect for all terrain. Kickstand to keep it upright. Great looking too!! Very nice bike! Thank you Influenster!

Easy to maneuver around

[This review was collected as part of a promotion.] This was the perfect upgrade for my elementary schooler just learning to ride a two wheel bike. It wasn’t hard to put together with easy to read directions. The tires were nice and it was easy to move and steer the handlebars around. It rode smoothly. This bike will grow with my daughter.

[This review was collected as part of a promotion.] My kids are OBSESSED with this bike! It’s beautiful, not too heavy, and rides like a dream. They love taking it to the local pump track or just riding around our neighborhood. My husband was impressed with there brand, he said ‘I always wanted a Mongoose when I was a kid!!’ Thank you!!

Cheap and poorly manufactured.

If you enjoy spending time on your day off switching out the cheap break handles this bike is great for you! Also three flats within a month (puncture holes were on the inside of the inner tube so from the rim of the bike… not from an exterior item).

backyard and pavement fun

[This review was collected as part of a promotion.] Assembly was a little frustrating in the beginning, regarding brake lines and confusion in the instructions. After that, assembly was a breeze. Seat is very firm so slightly uncomfortable at times. Performance wise, everything is aces.

Quality and good looking

[This review was collected as part of a promotion.] This Mongoose Index 1.0 bike goes seamlessly from neighborhood roads to the bike park. It’s a single speed with firm breaks for reliable stopping. The smooth black matte color is very cool. My son says it’s “cookin”. Recommended for youth 48”-54” inches tall. My 49” tall child has room to grow into the bike. Our bike was delivered and packed with exceptional padding. Every component was protected and in perfect condition. Assembly is mostly straightforward with the exception of the third brake cable. It took a while to realize the 3rd brake cable comes out of stem binder bolt. I felt like the instruction manual could be improved with more explicit instructions about this step. Required tools are in the review photo. You’ll save yourself some time picking this up in the store pre-assembled. Overall, the bike is great quality and will provide both of my children with many years of riding.

Well Built Little Bike!

[This review was collected as part of a promotion.] This is a super sturdy little bike. My 9 year old loves it. Very easy to put together and has all the features you need. Very well built and versatile. You don’t need to be a bmx rider to get good use of it! Highly recommend.

Excellent value for a quality BMX bike

[This review was collected as part of a promotion.] This Mongoose Index 1.0 bike is sturdy, easy to ride, and perfect for learning tricks. It looks sleek and sharp with its all black design and sturdy freestyle frame. It's built for kids between 7 and 13 years old, and the 20 inch size is perfect for growing riders who want to hit the bike park or learn tricks. The freestyle pegs and 360° rotor are a big hit, and the brakes work great. Assembly was pretty straightforward, and once set up, the bike felt very solid. The single speed drivetrain keeps things simple and low maintenance, which is a big plus. The alloy caliper brakes work well and provide reliable stopping power, giving me peace of mind when my kid's riding hard. What really sets this bike apart are the 4 included freestyle pegs and the cable rotor perfect for learning spins and tricks. My child loves trying 360-degree spins, and the bike holds up well through all the action. It looks cool, rides smooth, and feels solid definitely worth it for any beginner BMX rider. Overall, this is an excellent value for a quality BMX bike from a trusted brand like Mongoose. If you're looking for a durable, fun, and functional freestyle bike for a young rider, the Index 1.0 is a fantastic choice.

Great quality

[This review was collected as part of a promotion.] Easy to put together with the very detailed instructions. Bike is well built and will last a good long while. Packaging wasn’t the best because the box had a hole in it and part of the bike was stuck on the outside but it didn’t affect the bike. Great size for big kids and small adults to ride.

Great Every Day Bike or Trick Bike

[This review was collected as part of a promotion.] Thank you to Influenster and Mongoose for giving me the Mongoose Index 1.0 BMX 20" bike for free in exchange for my honest review. This bike arrived in several pieces and needed to be assembled with a few simple hand tools. The directions were easy to read and understand. They had pictures to follow along with. The whole process took under an hour. This bike can be used for everyday riding or to learn new tricks. The handlebars are made to rotate 360 degrees, so they do not get hung up on the front brake cable. The steel frame is heavy-duty and made to withstand jumps and drops. The 20-inch rims and tires have good traction on all terrains. There are front and back pegs that are used for grinding and allow better control for your tricks. They can be used to slide on rails or ledges with ease. This is a great bike for anyone to perform starter to advanced tricks.

Fun bike!

[This review was collected as part of a promotion.] My son has our grown his bike and needed an upgrade. We were very happy with this one. My son is just about 8 years old and about 4’2”. This bike fit him well with room to grow. It was a great price and he really enjoys the extras like the foot pegs and front and rear breaks. The assembly took about 45 minutes because the instructions for the brakes could have been better. All in all we are very happy and my son loves his new bike.

Do not buy

Tires go flat for no reason. We got an inner tube for the first one thinking we ran something over . Then the second tire went on it so we returned and got a new one. Tires went flat on the new one too. He has a smaller huffy that tires don’t go flat on. Going to have to return this altogether and get a different brand

Cheap components

Put this bike together for my five year old son today. Within several hours of him riding, the brake lever snapped at the hinge rendering it useless. My son is an excellent bike rider and only dropped it once or twice. I have been a moderately avid bike rider my entire life. No brake lever should break that easily.
