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!

Still working on it to get it 100% functionable . Many screws and bolts still not tight. Best to take it to a bike shop to assemble . My bike has an issue with the chain guard . An issue with the person at mongoose who assemble this bike . I do think it be a nice bike once everything works like it suppose too . Amazon had a good price too .

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

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!

You will need to take the bike to a bike shop for a tune up after assembling. The seat has to be the worst ever.

The chain keeps falling off the the gears are terrible. I love the color and the rest of the bike. I did change up the seat, the one that came with the bike wasn’t comfortable.

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!
