Description
Yotsuba Cycle is a sports bicycle brand specializing in kids’ bikes that was founded in Japan in 2016. Guided by the concept of “Bringing the Joy of Biking to Children,” the brand brings to life the bikes that parents—based on their own experiences raising children—want their kids to ride.
①: Lightweight Design
For growing children with limited strength, “lightweight” is one of the most important features. Even a single kilogram feels many times heavier to a child. Weighing only about half as much as a typical children’s bike, Yotsuba Cycle is easy for children to handle, so they’ll make rapid progress.
②: Sizes Optimized for Children’s Builds
If a child’s feet can’t reach the ground or they can’t grip the handlebars firmly, their fear of riding a bike will only increase.
Yotsuba Cycle is designed with a lower top tube to allow the saddle position to be lowered further. The handlebar grips are thinner (23.5 mm in diameter) than those on standard bikes, ensuring even children with small hands can grip them securely. Additionally, the crank length is selected for each bike size to match the target height range.
③: Brakes Designed Specifically for Children
If a child can’t stop when they feel scared, they’ll end up hating bicycles.
Yotsuba Cycle features slim levers that are easy for small hands to grip. Furthermore, the bikes are equipped with child-specific levers that can be pulled easily with minimal effort, along with V-brakes that deliver powerful stopping power, providing the peace of mind that comes from knowing they can stop safely even with a child’s grip strength.
④: Thick Tires
All models are equipped with wider tires that make it easier to maintain balance even at low speeds, helping children improve rapidly. Furthermore, the wider tires offer superior cushioning for a smoother ride and allow for serious off-road riding.
The 20-inch size supports riding performance that rivals even adults.
For kids who ride with a flair that puts adults to shame, we recommend the “Yotsuba 20,” equipped with 20-inch wheels. With a weight of less than 9 kg, a frame built for high speeds, and brakes that respond effectively with minimal effort, it delivers the essential “ride, turn, and stop” performance required of a sports bike.Once you get your hands on the Yotsuba 20—stripped of all excess and engineered for enhanced sports performance—the day you outpace Mom and Dad might be just around the corner!

Yotsuba Cycle’s Recommended Size Guide
At Yotsuba Cycle, with off-road riding on uneven terrain in mind , we recommend a bike where both of your child’s feet can firmly touch the ground when the saddle is in its lowest position.Therefore, rather than relying solely on age or height, please measure your child’s inseam and select a model from the size chart below where the saddle height at its lowest setting is less than your child’s inseam measurement.
