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.

Design is very nice. The frame and size seemed small for my height (5’6”). Very poor quality components which break easily so be careful with the assembly and fine tuning. Once one starts to assemble the bicycle, trouble starts. There were issues with every item that needed assembly. The instructions don’t help either. Make sure one fine tunes all the gears and derailleurs before riding the bicycle. Maybe Amazon should spend some money on assembly and fine tuning the bicycles it sells and after this sending them out to the customers fully assembled.

My nephew loves it

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.

Package arrived in rough shape. Holes and tears all over. Nuts in the handlebar collar hollow were loose. I knocked them back by accident and had to spend some time chasing them around and putting them back into place. Everything went together easily otherwise. Albeit, the shocks on the front fork feel very loose, and lack resistance for heavier riders.

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

Tubes not good. Bike wasn’t assembled properly. Seller said new but it looks used. Not happy.

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.
