Overview
This Outroad fat tire mountain bike pairs a 4 inch wide tire on 26 inch wheels with a 21-speed drivetrain and a high carbon steel frame. Dual disc brakes and a front suspension fork are included, and Outroad ships it with an installation video for the roughly 20 to 40 minute assembly.
Outroad markets it for both rough trails and urban roads on the strength of its wide tire and shock-absorbing fork, but one buyer who had it professionally assembled found the rear rim bent and the disc brakes poor quality straight out of the box. That same buyer also flagged that Outroad's return policy shifts shipping cost to the customer if they use a different carrier.
- 26 inch wheels with 4 inch fat tires
- 21-speed drivetrain for varied terrain
- High carbon steel frame construction
- Dual disc brakes with front suspension fork
Who it's for
Casual riders wanting a budget fat tire mountain bike for varied terrain who are comfortable inspecting or having a shop check the build quality on arrival. Not a fit for buyers who want dependable brakes and wheel truing without spot-checking.
Pros and cons
- 4 inch tires and 21 speeds for varied terrain
- Front suspension fork cushions rough trails
- High carbon steel frame
- Includes tools and an install video
- One buyer's rim arrived bent with weak brakes
- Stock pedals and seat felt basic to one shop
- Return shipping falls on the buyer per one review
Performance notes
The 4 inch tires are built for grip on loose or uneven surfaces, and the front suspension fork with a thickened outer wall is meant to absorb impacts on rough trails. The high carbon steel frame is designed to resist deformation under regular use. One buyer's local shop found the rear rim bent and the disc brakes to be of poor quality on assembly, so build consistency may vary.
