Mongoose Flatrock

Great bike, my son has gone through several pairs of tires and tubes already. This bike is a beast... I switched the front forks to an adjustable fork, I switched out the bolts for quick release skewers, I purchased the bottom crank bracket tools to tighten the crank, the brakes will be ready for new pads and cables soon. 2 years old and still rides like the day we bought it. I recommend buying bike grease, chain oil, pliers, 2 adjustable wrenches and allen tools to service and adjust the bike after long rides. Seat adjustment, tightening a loose hub, brake adjustment as the pads wear... I put a phone mount and mirrors on the bike for riding on bike/ running paths here in Sacramento. Good luck, I recommend this bike for 12-20 year olds who want to get some exercise and not spend alot of money.

I had a little bit of trouble getting the breaks set correctly but that was definitely my own incompetence. I watched a YouTube video & was eventually able figure it out. Overall it's a great kid's bike and very pretty!

It's a really heavy Mongoose but .. I knew that when I pressed the "add to cart" button. The hardware on the bike is mediocre but .. knew that. The bike does everything you need it to do .. unless you're a "bike person". If you ride this too hard .. it breaks. If you use it for transportation, or if you need a good beater for your kid who will be throwing this at the ground repeatedly until they move out of your house chasing some dream job in cosmetology or whatever nightmare they're dreaming of .. this is the bike for you. Assembly was complicated by the fact that it's just an okay bike. The tools they include are enough to assemble the bike with but, you can cut your assembly time in half if you just have some basic tools lying around the house. The bike rides and feels fine. With some fine tuning on the brakes and shifter mechanism, the bike would stop and shift fine. Solid "bang for the buck" on this but, if you spend another couple hundred bucks, there are better choices that would be worth much more than the extra investment. All in all .. this is okay and it's fine unless you're really trying to do anything outside the realm of "commuting".

If you're looking for a bike that's ready for anything, whether it's cruising around the neighborhood or hitting some easy trails, the Mongoose Flatrock is an awesome choice. I've been riding mine, and it's just a fantastic, reliable bike that makes getting out and about a joy. First off, it's really comfortable to ride. The front suspension (that's the "hardtail" part, meaning suspension in the front fork) does a great job soaking up bumps and uneven paths, so your arms and body don't take a beating. This makes longer rides or slightly rougher terrain much more enjoyable. Changing gears is super easy with the 21-speed twist shifters. Whether you're going uphill and need a lower gear, or flying downhill and want to pick up speed, a simple twist of the wrist gets you where you need to be. It shifts smoothly, so you're never struggling to find the right gear. I also really appreciate how lightweight yet sturdy it feels. It's easy to maneuver, which is great for weaving through paths or even just getting it on and off a bike rack. And when you need to stop, the brakes are reliable and give you plenty of stopping power. Overall, the Mongoose Flatrock is a fantastic bike for anyone who wants to enjoy the outdoors. It's built tough, rides smoothly, and is just a lot of fun. Whether you're a casual rider or looking to explore a bit more, this bike is a great companion!

My husband and I recently bought the above bike on Amazon for our son for his birthday. We studied reviews and felt good about this being a good bike for a big kid--he's almost 6' and a stout guy. He loved the look of the bike; however, after a couple weeks of use, we've been very disappointed in the quality and functions of the bike. Here are several items of note: 1) The handle bar--this bar, although sleek looking, does not offer much room for adjustment and it is very uncomfortable, even painful, to ride for our son, me (5'8") and my husband (6'1"). We all experienced pinched shoulders and neck even after riding it just around the block. A neighbor helped us put a different handlebar in to raise the grip a bit, and although it helps, it's not quite the right size for the bike, the overall grip is still pretty narrow. Which means we will have to keep shopping around to make adjustments. 2) The handle grips and gear shift--these are entirely too small and spaced too close together! My son's hand, if he grips with a standard 4 finger grip, overlaps with the gear shift, so gears are shifting when he's just holding on to the handlebars and not meaning to shift gears. 3) The pedal/crank set--there is a decent amount of wiggle room in this. As I understand, this should be a pretty sturdy feel, but it jiggles. It doesn't appear that this is anything we can adjust, it is as it came. We had the bike professionally put together, and the mechanic noted this right away. 4) The kickstand--it has already bent and bends forward with the weight of the bike and no longer works. Overall, we are extremely disappointed in this bike. We feel that for the money, we shouldn't be having all these issues right away with it. We reached out to the manufacturer, and have not heard any response back. I'd shop for a different bike!

Ugh was excited for this to come in and now I’m debating on returning. I haven’t even been able to assemble it because it didn’t come with tools to assemble it. I have to find someone who will prolly have the tools. For almost four hundred bucks you guys can add the tools with the purchase! Bike is cute but definitely could be 100% better. I’m honestly unsatisfied and probably gonna end up returning it honestly.

We just gave this to our 10yo son for his birthday and we are very happy with it. I was torn between purchasing a 24inch or 26th inch, but the 24inch is perfect. The frame size coupled with the 24inch wheels is the ideal size for him, the larger size would have been too big. For reference he stands at approximately 4ft 8in, and he still has lots of room to grow with it. I am 5ft 3in and can also ride it. Walmart advertises this size as being suitable for 10-14yo and I think that is pretty accurate. The bike is not the lightest compared to higher end mountain bikes, but this will be used for neighborhood riding and going on park trails. And for the price, I was expecting a solid feeling frame. First impressions tell us the quality is good, comparable to any other bike. It was very simple to assemble. We did take it to a local bike store to have the gears checked and brakes tightened, but it was ridable out of the box. Overall for the price, we are really happy with the size and quality of this bike, and our son loves it!

Easy to assemble. My grandson has had hours of enjoyment riding this bicycle. This is not a high performance mountain bike but is perfect for riding around the neighborhood.

Fidèle à la marque vélo de bonne qualité, léger et mon fils adore le style.

I like the bike, but it is not for an adult, it is for a teenager. Also have some problems with pedal

This is not a 21 speed bike. It is a 7 speed. But besides that it was simple enough to put together. Brakes required extra tuning and front rim was a little warped.
