Overview
The Avasta AV300 is an aluminum-frame mountain bike available in 26 or 27.5 inch wheel sizes, with a 21-speed derailleur, front suspension fork and dual disc brakes. It ships about 75-80% pre-assembled with the remaining hardware and tools included.
This is entry-level hardtail territory: the fork uses coil springs rather than air, and stock tires lean toward street tread rather than aggressive knobs, so a few owners swapped tires before hitting real trails. Assembly quality out of the box varies a bit by unit, with at least one report of a bent derailleur hanger on arrival.

Who it's for
Suits budget-conscious riders and parents buying a first mountain bike, plus casual trail riders sticking to easier terrain rather than technical singletrack.
What buyers say
From Amazon customer reviews.
Most owners called the AV300 a strong value for the price, describing smooth shifting and firm braking once minor adjustments were made after unboxing. Reported issues include one bent derailleur hanger on arrival, a quick-release front wheel that did not stay closed reliably for one buyer, and stock tires better suited to pavement than technical trails.
Strengths and trade-offs
Drawn from this product's published specifications.
- Aluminum frame keeps weight down
- Ships mostly pre-assembled with tools included
- Dual disc brakes stop firmly once adjusted
- 21-speed drivetrain shifts smoothly after setup
- Stock tires are closer to street tread than trail-capable
- At least one unit arrived with a bent derailleur hanger
- Quick-release front wheel reported loose by one owner
- Coil fork is not adjustable like an air fork
Performance notes
Shifting and braking commonly need small tweaks after unboxing, tightening a caliper or adjusting cable tension, after which owners describe smooth gear changes and firm stopping power. The quick-release front wheel has been reported by at least one owner as not staying closed reliably even when cranked down, worth checking on arrival.

Questions about the Avasta BA8005HK26gre
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
How much assembly does the Avasta AV300 need?
It arrives about 75 to 80 percent built, with owners reporting roughly an hour to finish the fork, handlebars, seat, pedals and brake and shifter adjustments.
Are the stock tires good for real trail riding?
One owner described the included tires as closer to slick street tires and swapped them out before serious trail use.
Does the AV300 have an air suspension fork?
No, the front fork uses coil springs rather than air, so it is not independently adjustable.
