Additional Features

Timberjack Kids Geometry

The geometry of our Timberjack 20 & 24 accommodates the different riding style and abilities of younger riders. Kids steer by “pushing” the handlebar left and right and “response leaning” rather than leaning and “response countersteering” like adults do. This combined wit the lower strength of a child relative to an adult means that the steering and handling needs to be quicker and more responsive than a “normal” mountain bike

3-Inch Plus-Sized Tires

For floatation, traction, and most importantly, added stability that can help smaller bodies stay upright in loose conditions

Aluminum 6061-T6 heat-treated frame

Strong, rugged, and lightweight, and built to persevere in the world of the young adventurer. “Full-size” features include internal cable routing for the rear brake and front triangle bottle mount

Timberjack Kids Aluminum Fork

Our rigid fork includes Three-Pack mounts on each fork leg, allowing kids to carry extra waterbottles or gear, just like mom and dad’s bikes

BOOST Width Hub Spacing

Uses modern, plus-bike spacing with bolt-on hubs

1 x 8 Narrow Wide Drivetrain

Easy to learn and operate with one twist shifter

Parts That Fit Smaller Bodies Better

Size specific saddle, adjustable brake levers for small hands and safer stopping, and small pedals to better fit smaller feet
