Mongoose Grafton Mountain Bike, 21 Speed, Aluminum Frame, Knobby Mountain Tires, Suspension Fork, Trigger Shifters, Mechanical Disc Brakes

Very good quality for this money. Added for my wife and daughter.

The bike showed up fine. But step one is to install the handlebars. But one of the bolts on the goose neck cam stripped and cannot be removed. So I need to replace the whole goose neck before I can go to step two. Definitely would not recommend

High quality bike. Great price for the quality. No issues.

So, when putting it together out of the box I noticed one thing; the front brake disk is bent and rubbing against the pad or the bolts.. I took it off altogether after I couldn't pound it back flat,and now going to have to buy a front disk. One other thing is the shifter design conflicts with a plastic mechanism next to it. Im being generous with 4 stars. Not sure if I should contact support for this or leave it alone. Buy at your own risk.

Our bike was impossible to put together as one part had fallen inside the handle bars, it was what the screw needed to go into, so my son was building and the screw seemed to be wrong until we realized what happened. Required much more taking apart and gluing parts in which should not have happened with a brand new bike. Also the tubes keep going flat after storing it overnight in the shed. and the brakes are terrible. They lock and they don't react quickly. For this price, we are very disappointed in this bike. It's already going to need a trip to the bike shop to fix these problems.

Overall this is a good bike for the price. We did have to get a replacement stem before we could use the bike but it was covered under the mongoose warranty. It arrived directly from mongoose in about a week.

Beautiful bike. Good quality. Smooth ride.

CAUTION! The chain falls off when using certain gears; Out the box, it was built as specified by instructions. When I went on my first trail the gears were grindy, noisy, and worrisome. I’m sorry, but my Chinese off brand bike was flawless out the box

Well bike is fine. Bottom bracket bearings loose. And rear tire bearings open as well. All in all you get what you pay for. Just have to spend a couple hundred getting it fixed. When it's new there should not be this issue.

La quincaillerie n’est pas dans la boîte et j’ai l’impression qu’il manque un disque… Super…

I couldn't attach my handlebars because the joiner piece had a wonky bottom screw hole. Super annoying as it added weeks to me being able to actually use my bike.
