- Switch and Stun

**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!

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.

The bike is very cool. But, there were issues ... first, the box was damaged which only affected the cosmetics of the bike. But, once you open it up, it is hard to consider returning. Anyway, we decided to proceed ... the bike seemed simple to assemble except 2 key parts were missing - a bolt for to secure the seat and an inner element to secure the handle bars. The customer service process was exceptional, the service tech answered the phone and was responsive. The only problem is this was Friday afternoon and my grandson wanted to ride the bike. So we took it to a local Recyclery Bike Store in Charlotte and they were wonderful and providing the missing parts. We love the bike, but the quality control for making sure the right pieces were included is a 0 or 10 rating. Funny, we had 2 additional pieces included which we have no idea what they are for, so I'm sure some other customer is looking for parts. LOL!

Ok so im gonna start off by saying all the other reviews of this bike were by people who have 0 experience with ANYTHING mechanical. I had zero issues putting this together in the 45 minutes it took me. That included unpacking the bike, greasing all the bearings and putting it together. The other reviews that complained the handle bar stem came upside down were only half right. Yes they came packaged upside down...you have to loosen the bolts and adjust the stem to sit correctly on the bike then tighten the bolts back down. They package them like that to fit in the box. If you have no mechanical knowledge of the simple things (like a bike) you shouldn't be attempting to put one together! Anyway...For $99 im happy with the quality. The rims are true and the frame is solid! No problems for me and the best part is....My son loves it! Win win for this Dad.

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.

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.

I read all the reviews before buying. Assembly reviews had me scared. It was actually really easy to put together. The only thing I recommend it looking for a you tube video to follow. The printed directions aren't really clear. Just search mongoose switch and choose the one with the guy in the red Chiefs shirt. Some users here said they had to assemble the brake system but mine came assembled.

We got this bike for our son's 5th birthday. While my husband was assembling it he noted that something with the handle bars was pre-assembled backwards in the handle bars/stem. He easily reversed this, but when he got to the peddles and could not get them to screw on (they wouldn't thread), I took a closer look and discovered that the Left and Right stickers were placed on the incorrect peddles (you could see a small R and and small L etched into the plastic on the peddles). When we reversed the peddles they screwed in perfectly. We gave the bike to our son after assembling it and he rode it around for a short time. Due to the holidays we put the bike in the garage and 2 days later when we went out to use the bike again the front tire was completely flat. We pumped it back up and you could hear air leaking out of the tire tube inside. When my husband took the tube out there was a visible slit in one of the seams on the tube. So that being said, the bike is nice. My son really likes it, but from an adult perspective it has been a bit of a hassle from day 1. I contacted Amazon and they gave me a 20% refund (which will cover the cost of purchasing a new tube). Now we have to get a new tube and put it on before my son can get back on that new bike.

Calidad, diseño y resistencia. Un excelente producto, una bicicleta muy bonita, de gran calidad y funcionalidad, altamente recomendable, precio acequible.

Très bon vélo de bonne qualité

Ninguna queja con este producto, si pudiera poner un "pero" sería el peso de la bicicleta pues si es algo pesada, pero todas en esta categoría lo son. La relacion precio-calidad es muy buena. Muy recomendable

I was afraid of few reviews that I saw before receiving it but very happy with this purchase. I had to unscrew the front axle as well as the crankset as they were difficult to turn but once these adjustments are made everything is perfect and my 6 year old boy is very happy. Nice intermediate size.

For the price I was expecting better quality than the low end big store options. It's a nice looking bike and was decently packed but the front wheel rim was scratched and 2 axle nuts and a washer were missing. The front bearing was very tight and the wheel barely rotated on the axle, adjusting the preload made it ok. The pedal crank was tight, seizing and made clunking noises, loosening the bearing nut did not help, the bike was un-useable and I returned it. I would recommend trying the pedal crank before proceeding with assembly.
