- 29 inch wheels on a 6061 aluminum frame
- 21-speed twist shifting
- Front suspension fork
- Fits riders about 5-foot-4 to 6-foot-2
Who it's for
Works for beginner and casual riders wanting a budget hardtail for mixed terrain, including as a first bike for a teenager. Not the choice for riders who put in serious trail mileage, since gear shifting and brakes have drawn durability complaints after a few months of use.
Pros and cons
- Arrives mostly assembled with an online setup video
- 21-speed shifting covers flat roads to rougher trails
- Front suspension fork softens bumps on uneven ground
- Aluminum frame and double-wall rims keep weight down
- Gears have been reported to twist or bind after a few months of use
- Front brake and handlebar assembly steps have confused some buyers
- Suspension has been described as stiff by at least one rider
Performance notes
The 6061 aluminum frame pairs with 29 inch wheels and wide, knobby tires for grip on mixed and off-road terrain, while double-wall rims add strength without much extra weight. A 21-speed twist shifter handles gear changes and a front suspension fork is meant to absorb bumps, though one rider described the suspension as stiff out of the box. Aluminum V-brakes provide stopping power front and rear.
