Precaliber 24 8-Speed Suspension is a versatile kids' bike built for young adventurers who love riding off the pavement and into the dirt.

For kids ages 8-12, between 51-59˝ tall.

It's right for you if...
You love exploring nature on your bike, and your kid loves adventuring with you! You're looking for a high-quality kids' bike that's comfortable, durable, and has trail-ready parts for your up-and-coming singletrack shredder.

The tech you get
A strong, lightweight aluminum frame, a simple Shimano 8-speed drivetrain that's easy for kids to handle, and a front suspension fork with 45mm of travel to absorb bumps. Plus, a kickstand, rear rack mounts, and a saddle with an integrated handle that can be swapped out for an integrated taillight mount. Everything on this bike is built to last, so it'll still feel like new when handed down to younger siblings.

The final word
This rugged, high-quality bike encourages fun and skill-building on the trail. It's perfect for kids who are getting into off-road riding, with a trail-smoothing front suspension fork and an 8-speed drivetrain.
