The perfect blend of performance, value and fun, the Marin Bolinas Ridge is ideal for riders that are new to mountain biking or simply want a low-hassle, low-cost bike to explore off-road.

With a lightweight aluminum frame, a trail-capable suspension fork, MTB tires and all-conditions disc brakes, the Bolinas Ridge has everything you need to break out onto the trails and push your own boundaries.

The Bolinas Ridge 2 is our upgraded Bolinas, stepping up the fun and the components. The Bolinas Ridge 2 gets an upgrade to Clarks Hydraulic disc brakes and features a SR/Suntour suspension fork, reliable and grippy off-road tires and plenty of kick-ass Marin components. The Bolinas is ideal to break out onto the trails and push your own boundaries.

Depending on size, the Bolinas Ridge comes with either smaller 27.5 (sizes XS to M) wheels or larger (sizes M to XL) wheels to guarantee a perfect fit.

Key upgrades over the Bolinas Ridge 1:

• Shimano Altus 3×8 drivetrain
• Clark’s hydraulic disc brakes
• SR/Suntour XCM DS fork
