Q: Does this bike have 360 handlebars?

submitted by Ree - 24 days ago
  • A: This bike has a generous amount of brake cable to allow for bar spins, but since it does not have a detangler system (sometimes referred to as a Gyro), it cannot do so indefinitely. The brake cable must therefore be periodically unwound.

Danger

I was so excited to gift this bike to my son this morning for Christmas! I picked it up from target already assembled! He hops on the bike and is riding for a little while and while riding the front wheel comes off!!!! Yes the front wheel while he was riding! I am posting this to warn any others because luckily he did not get injured but this is a huge safety hazard! And target is making it difficult for me to try and return or get a refund for an item we are going to have to try & fix ourselves!

Dont buy uniess you want to pay more money for tires

Went out of our way to get the only bike left in town and get it all the way back for it to have a bad tire that won’t keep air. So now my guy has to take apart the bike, take off the tire, and spend more money to replace the tube on a brand new bike that is unusable. Buy anything else but this one unless you want to ride around with flat tires. Target won’t fix the issue because they don’t air up the tires so if there bad it’s not their problem it’s now yours.

perfect bike for kids who love ramps, rails, and t

[This review was collected as part of a promotion.] I received this bike for free in exchange for my opinion. The Mongoose Index 1.0 Boys’ 20” Freestyle BMX Bike is a solid, durable bike that’s perfect for kids who love ramps, rails, and trying new tricks. The single-speed drivetrain keeps things simple, and the alloy linear-pull brake gives reliable stopping power. My son’s favorite part is the four freestyle pegs, gives it a BMX setup feel. It was easy to assemble by a few boys with basic tools, and the 20-inch wheels are a great fit for big kids. Overall, it’s a sturdy, fun bike that can handle plenty of rough-and-tumble riding.

Great for a 7 year old!

[This review was collected as part of a promotion.] This bike is amazing!!! My 7 year old LOVES it! Now that he’s learned how to ride a bike, I cannot get him off of it. The seat is sturdy and comfortable, the handlebars are placed perfectly for his size, the frame fits him so well. This bike is everything we hoped it would be!

My son uses it daily - he loves it!

[This review was collected as part of a promotion.] My son’s Christmas present- he uses it every day to ride around with his friends on and off the street. I can tell that it is made very well and safe for him to use. I have rode it myself and can say it rides super smoothly - totally makes me want one for myself, lol. It even comes with front and rear pegs!

Fun and comfortable ride

[This review was collected as part of a promotion.] This bike was easy to put together and very comfortable to ride. As an adult who tried it, I thought it was smooth and easy to get going. The kids like off-road type riding, and this bike was excellent for that as well. The tires grip the dirt just like asphalt. It's fun to ride on all terrain.

Ferocious looking mongoose bike

[This review was collected as part of a promotion.] Excellent bike with great materials and easy assembly. You can tell the mongoose is great because of the quality materials and the household name. The seat is comfy for my 10 year old and the bike looks ferocious.

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!

Kid approved!

[This review was collected as part of a promotion.] I received this product complimentary in exchange for a honest review. My 11 year old son absolutely loves this bike. It looks great, we both love the blue lettering on it. It was simple enough to put together with easy to read instructions. Rides smooth and is comfortable. It’s the perfect size for him and he has room to grow with it which is nice. Haven’t had any issues with it so far, brakes work, son says he wants different grips but I think it’s more for looks than comfort. All in all great bike. Sorry about the photo being of the box, once we got the bike together he just took off didn’t have the patience for mom to take pictures.

Awesome bmx bike for beginners

[This review was collected as part of a promotion.] This Mongoose BMX looks so cool! It was easy to assemble and only took me 5-10 minutes. I did use my own tools for the assembly since it did not come with an Allen wrench or pliers. This is a great beginners bmx bike.

Instruction manual difficulties

[This review was collected as part of a promotion.] We thought this bike was going to be an easy assembly but there was one complicated part. The instruction manual is just a general instruction manual for all of Mongoose bikes so the pictures were exactly right for what we were looking at. When it came time to assemble the handlebars we had issues because a part of the bar was stuck down in the hole and this created issues with getting the handlebars turned the correct way. Mongoose really needs more specific manuals for their bikes. It rides well and my son likes it though. He’s still learning to ride and I think it’s a good size for him.
