Overview
A 27.5-inch aluminum-frame mountain bike with a 24-speed Altus and Tourney drivetrain, a lockout suspension fork and mechanical disc brakes, sold in three frame sizes for adult riders.
The drivetrain pairs a Tourney EF500 3-speed shifter and Tourney TY300 front derailleur with an Altus M310 8-speed rear derailleur for 24 total gear combinations, a mid-range setup rather than a premium groupset. Internal cable routing on an aluminum frame is a detail more common on higher-priced bikes, and the listing calls it out specifically. Total bike weight is listed at 14.6 kg with a combined rider-plus-cargo load limit of 100 kg.
- 27.5-inch aluminum frame, 24-speed Altus and Tourney drivetrain
- Lockout suspension fork with spring preload adjustment
- Mechanical disc brakes front and rear
- Three frame sizes: 16-inch, 18-inch, 21-inch
Who it's for
Adult riders shopping for a mountain bike sized to their height, since three frame sizes cover roughly 5-foot-3 to 6-foot-6, who want a lockout front fork and disc brakes for mixed trail and commuting use. Not aimed at riders needing full suspension for aggressive downhill terrain.
Pros and cons
- 24-speed Altus and Tourney drivetrain for a wide gear range
- Lockout suspension fork for climbing vs descending
- Internal cable routing protects lines from mud and debris
- Three frame sizes matched to rider height
- Front suspension only, no rear suspension
- Mechanical rather than hydraulic disc brakes
- No rating or review data on this listing
Performance notes
The lockout switch on the suspension fork is a mechanical spring preload adjustment, toggling between a firmer setting for climbing efficiency and an open setting that absorbs impacts on descents, rather than an electronically adjustable damper. The 27.5x1.95-inch tires use a reinforced casing aimed at puncture resistance from thorns and debris, which matters more for off-road use than smooth pavement.
