Mongoose Flatrock 21-Speed Hardtail Mountain Bike, 24 to 29-Inch Wheels, for Men Women Boys and Girls, Front Suspension, 14.5 to 18-Inch Aluminum Frame Options

I live in a medium-sized neighborhood; I bought this bike to more easily travel within my neighborhood without having to use my car for very short trips. I have never assembled a bike before, but I was able to assemble this one quite easily. The instructions were a bit confusing, because instructions are included for several different versions of the bike, but once I acclimated to which instructions were applicable to me, it wasn't very hard. I did have to purchase a few items for assembly, but they were not very costly, and they will be useful additions to my toolbox. Assembly really only entailed attaching the handlebars, seat and pedals. All of the gear mechanism was already assembled. The bike is easy to ride and operate. So far, I'm completely satisfied with this purchase!

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".

Legendary reliability and development on full display with this large, capable, and comfortable Mongoose mountain bike!

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!

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!

Its alright. I had Mongoose a long time ago and thought this would last longer for my son than the Huffy that started breaking in a year. Unfortunately we've replaced plenty of parts on this already also. Just not made as well anymore.

Arrived undamaged, box was in perfect condition. Instructions were a bit confusing at first, but once i studied them closely and figured out which type of bike parts i had, assembly was a breeze. Bike looks great in dark purple, very stylish. And best of all, it rides great!

Beautiful bike. Had to get the tool separate to set it up. The set up was a bit more difficult than I anticipated, but defiantly worth it for the finished product. It had a quality frame and beautiful tires, as well as the beautiful blue color through out. Would recommend for an overall quality bike for anyone looking to purchase.Thanks to the seller.
