The Youth Model Y/1 was conceived for the junior adventurer to keep up with and climb past their mentors. Everything has been intelligently considered: weight reduction, more durable componentry, two sizes that specifically accommodate for kids and their growing proportions, corrosion-proof inner and outer tube coatings, and, most importantly, redefined superior fit and feel. These advantages have been carefully engineered into a capable bike that delivers a ride feel that will drive them to go bigger and climb higher every time they roll up to the trail head. The Y/1 Mountain 20" has been designed for kids in the prime bike-riding age range of 5 to 8 years old. In addition to a smooth-shifting 1X drivetrain, carefully thought-out geometry, and age-appropriate componentry, the bike features grown-up technology like hydraulic disc brakes, air suspension fork, and specifically tuned return springs. This is not a kid's toy. This is a legit mountain bike. It is perfect for enthusiasts from 5 - 8 and parents who want their youngsters to have the same access to adventure they enjoy, themselves.

Step up from the Coast Trail 16", and see the spec progress, just like the young rider in your life. The Coast Trail 20" 1 is built around a lightweight aluminum alloy frame and fork, but with the addition of a simple and dependable single speed drivetrain - perfect for a growing rider who is able to get out for the ride to school, to the park or out on your neighborhood paths. LIGHTWEIGHT ALUMINUM FRAMES & FORKS - Coast Trail models are all built upon lightweight Series 1 aluminum frames and aluminum forks. This ensures that your young rider won't be held back by a heavy bike, as a lighter bike is easier to control and balance. The weight savings goes beyond the frame, and we ensured that every component spec'd offers the best balance of weight to durability. KIDS-SIZED COMPONENTS - Kids are smaller all over, so our designers took that into consideration when designing the Coast Trails. Handlebars and grips are of smaller diameter than found on adult bikes, brake levers are specifically designed for smaller hands, and even the pedals and saddles are proportionally smaller. This helps kids maintain comfort and control while they are still developing their skills as riders. SMOOTH-ROLLING 2.0" TIRES - Smooth-rolling Marin x Vee Tire 2.0" wide tires are used on all Coast Trail models, with smooth center for easy riding on paved surfaces, and inverted tread on the sides for added safety when the paths are rougher.

We took our Matt Jones-inspired Marin San Quentin and shrunk it down to fit 20" wheels. It's the perfect bike for kids who are ready for their first proper, hardcore hardtail mountain bike. The Marin San Quentin 20", just like the big kid's version, shreds the boundaries of the mountain bike genres - doing it all with a huge splash of big air, speed and style. Designed with the input of freeride legend Matt Jones, the San Quentin takes the DNA of our dirt-jumping Alcatraz and mutates it into a go-further and faster all-round, hardcore hardtail. The San Quentin 20" will feel just like a 'grown up' mountain bike to your little ripper, built with a stout Series 2 aluminum frame, 20" wheels, an SR Suntour XCM suspension fork, 8-speed Shimano drivetrain and kid's specific hydraulic disc brakes. SERIES 2 ALUMINUM FRAME - San Quentin 24" and 20" both feature a Series 2 aluminum frame, with a tapered headtube, 3D forged dropouts, IS brake mounts, semi-internal cable routing and 135mm open dropouts. DIRT JUMP INSPIRED FRAME STYLE - Taking cues from the Alcatraz, as well as the full-size San Quentin lineup, the San Quentin 24" and 20" proved all the benefits of DJ style, with massive standover, slick frame tubes, and a hot paint job. MODERN TRAIL GEOMETRY - A slack headtube angle paired with a steep seat tube angle creates a ride that will fly uphill, yet descend like it's on rails. The balanced rider position is puts the rider weight between the wheels for steady climbing and handling on flats, while the slack front end helps to add higher speed stability through turns and rough patches. 1X WIDE-RANGE DRIVETRAINS - Modern 1x drivetrains, just like the larger San Quentins, give the rider the benefits of shifting simplicity and chain retention.
