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.
A kid's first Marin. Our neighborhood bikes are designed with young riders in mind. All models feature lightweight aluminum frames, kids-sized components such as short reach brake levers and scaled down grips, saddles and pedals. Smooth tread tires roll efficiently, while strong linear pull brakes stop on the proverbial dime.
