For neighborhood cruises and sidewalk races

Precaliber is perfect for practicing turns in the driveway, racing down the sidewalk, and taking a family spin around the neighborhood. Wide, stable tires and a light, easy-to-handle frame give kids the confidence to pedal across the yard and down the occasional gravel path.

Designed with kid-friendly features

Each of our Precalibers and all of their parts are designed specifically for kids, by people who know bikes. They’re lightweight, built to hold up to rough and tumble play, and have size-appropriate grips, levers, pedals, and saddles. We put a lot of thought into getting the details right, because we know positive and fun experiences with biking at an early age can encourage a lifelong hobby.

Easy to hop on and off

Precaliber's frame is lower than most kid's bikes, which provides more confidence when mounting and dismounting.

Handle or light - you choose

The kid-sized saddles have an integrated handle for easy lifting and guiding while they ride. It can also be swapped out for a tail light to boost visibility.

Wide tires, more traction

Wider tires are more stable and offer better grip. It makes kids even more confident and comfortable while riding.

12" + 16" wheels - great for the youngest riders

These Precaliber models are designed for ages 3-6, and they all come with training wheels. They’re perfect for kids who are just learning to ride but are too big for a balance bike, and for children who prefer to ride with training wheels until they feel a bit more comfortable on two wheels.

Tool-free training wheels

All 12 and 16" bikes come with training wheels that are easily removed with the twist of a knob once they're no longer needed. No tools required!

Kid-sized hand brakes

Some 16" bikes come with hand brakes, which is a great option for children who have the hand strength and coordination necessary to start learning how to use them.

20" + 24" wheels - more features, more chances to learn

These larger Precalibers are designed for kids ages 6-12 who have a good command of basic bike skills and are ready to tackle more. They have lots of different combos of brake types, and speeds so you can pick the perfect bike for your child's skill level.

Lots of gearing and brake options

We want you to be able to pick a Precaliber that's perfectly suited to your kid's age and skill level. That's why we offer models with different numbers of gears and brake types.

For example, fewer gears are great for kids who are just getting used to them, while older kids with good hand strength and coordination can generally handle additional gears.

Roll over the rough stuff

Some 24" bikes have mountain bike-styling and suspension forks for kids who want off-road looks and a smoother ride while biking over bumps.
