Overview
A rider moving from neighborhood paths to rougher trails gets an aluminum Montana Sport with a suspension fork and mountain tires. Gears are changed by trigger shifters, and cable-pulled discs handle the stopping.
Larger wheels and a front fork add traction and comfort on rough ground, and the long frame warranty is notable. The limitation is that the frame comes in one size here and the listing does not say how much assembly is needed.
Who it's for
A taller adult who wants a geared trail bike with front suspension. Riders under the minimum height, or those wanting hydraulic brakes or rear suspension, should look elsewhere.
Pros and cons
- Front suspension fork
- Wide gear range
- Mechanical disc brakes
- Long frame warranty
- Fixed frame size
- Mechanical, not hydraulic, brakes
- Assembly details not listed
Performance notes
The fork absorbs trail bumps and the larger wheel size rolls over roots better. Front and rear derailleurs combine to give the gear range for climbs and descents. Mechanical disc brakes act by cable, so they need periodic adjustment.
