AVASTA Earth 26 27.5 inch Mountain Bike with 21-Speed，Dual Disc Brake, Comfortable Saddle,Multiple Colors

Very nice looking bikeEasy to put together took me less than 30min

Some assembly is definitely required, as you would have a ready-to-ride experience if you were to buy a similar bike at a bike shop. The bike comes well packaged, but that packaging means you'll have to take a chunk of your afternoon clearing a space to assembly and torque down all the critical parts on this otherwise respectable quality bike; probably among the better bikes you'd find at a generic sporting goods store or wholesale. The instructions, while not perfect, do give you most of the information you need to get the bicycle assembled safely so you can go for a ride the same day, bike repair shop be damned. If you're mountain biking, you need to learn how to fix your bike on the trail anyway, so it's all in the spirit of it.Once you're assembled and taking it for a spin, you'll inevitably find that a few components need to be adjusted, but the stem being off a bit was slightly annoying. I would understand if you took a downhill header into a rocky ridge and threw the alignment off, but I would expect that to be straight, true, and torqued to spec from the factory. Imagine if you bought a car and needed to bring it in for alignment within the first 100 miles.These criticisms aside, there is a lot to like about this bike. Dual disc brakes are vastly superior to traditional caliper setups. Adjustable front suspension used to be luxury bike territory. Shimano suspension and braking components keep the experience crispy and responsive. Thoughtful cable runs through the frame tubing keep things neat, but good luck with mud and hosing down your bike after a hard, muddy ride.Overall, the bike is a solid contender for an budget, upmarket mountain bike. The assembly and materials of some of the systems are a bit lacking and would beg the question of whether this bike will be replaced within the next 5 years. For my riding and experience, I would think yes, but I feel that it's value-conscious pricing forgives all the clipped corners on this great trail riding vehicle.POST-RIDE EDIT: After going on a bit of trail riding, I'm happy to report the bike has proven itself fairly competent. The front suspension bottoms out, but I believe that will go away with a bit of adjustment. The Shimano transmission has crisp shifting up and down the hills and the tires grip well down hills and around berms. Brakes needed some initial adjustment and are responsive and confident when you need them. As far as balance, the frame's geometry is not perfect, nor would I expect anything like that at this price; keep your hands on the handlebars. The seat is also soft and forgiving, which I appreciate as the years roll on. I reiterate that is a terrific entry-level bike that will get you out and in the trails with more than a few dollars to spare on snacks and accessories.

Quality and sturdiness at a good price.

This is a very nice bike at a value price. It arrived packaged very well. There was way more assembly required than I expected. I took my time and got it assembled and learned a lot about bikes at the same time. The disc brakes are a great feature that I have never had on previous bikes. Has Shimano components. The tires are good for pavement or the campground trails that I ride. The suspension can be adjusted to fit your riding style. I ordered the red/black color pattern and love the look.
