Overview
A 29-inch aluminum alloy mountain bike with a front suspension fork, 3x7 (21-speed) drivetrain and dual disc brakes. Positioned as a budget option for mixed road, trail and commuting use.
The frame and component list read like a standard entry-level mountain bike, but the one detailed review on record raises two concrete issues worth weighing before you buy: assembly is more involved than advertised, and a rear tire failed at a pressure below its stated rating.
- 29-inch wheels on an aluminum alloy frame
- Front suspension fork for vibration reduction
- 3x7 (21-speed) drivetrain
- Dual disc brakes
Who it's for
Buyers comfortable doing real mechanical assembly themselves, or willing to pay a local shop to finish the build. Not a fit for someone who needs a bike that's ready to ride straight out of the box with minimal tools.
Pros and cons
- Aluminum alloy frame with front suspension fork
- 21-speed (3x7) drivetrain covers a wide gear range
- Dual disc brakes front and rear
- Adjustable seat post for different rider heights
- Requires more assembly than advertised, per at least one reviewer
- Instructions described as close to useless
- One reported rear tire failure at 30 psi
Performance notes
The front suspension fork and 3x7 drivetrain are built for a wide gear range across hills and flats rather than serious off-road use, and dual disc brakes provide the stopping power. One reviewer's report of a rear tire failing at 30 psi, well under its stated rating, is a specific enough detail that buyers should check tire pressure carefully and inflate gradually the first time.
