Marin Donky Jr. SE, 24" Wheels, Matte Red/Black One


The Donky Jr. family consists of lightweight aluminum-frame bikes, using four different wheel sizes, and are perfect for first-time riders.

A kid's first Marin. Developed in conjunction with our friends at Marin Bikes Japan, the Donky Jr. family of bikes are designed with young riders in mind. All models feature freewheels and handbrakes, making it easier for them to transition to larger bikes as they grow. Smooth tread tires roll efficiently, while strong linear-pull brakes stop on the proverbial dime.

Why you'll love it:

Built around a lightweight aluminum frame, dependable Shimano 6-speed drivetrain, kids-sized saddle, grips and controls, along with the quality components you expect from Marin. Perfect for neighborhood adventures, where each block away from home feels like a mile.
