Seller copy for this listing mixes the Uokaa and Tiaw names for what appears to be the same bike, with the 21-speed version highlighted as the higher-performance drivetrain option.
- 19-inch aluminum frame with 29-inch wheels and 2.1-inch tires
- 9 or 21-speed drivetrain options
- Front suspension fork with ergonomic seat design
- Front and rear disc brakes
Who it's for
Fits riders, including taller ones at 6 feet 3 inches based on one review, who want a budget aluminum-frame mountain bike for mixed terrain. Less suited to riders who want to swap in a different saddle easily, since the seatpost size is nonstandard on this model.
Pros and cons
- Dual disc brakes for consistent stopping
- Shifting works correctly out of the box for most buyers
- Ships around 85 percent pre-assembled
- Stock seatpost is a nonstandard size, making the seat hard to replace
- At least one unit arrived with a defective derailleur
- No phone number listed for customer support, per one reviewer
Performance notes
The aluminum frame and front suspension fork are built to absorb rougher terrain, and the dual disc brakes give consistent stopping power front and rear.
