Frog 58 Road 20" Kids Bike
- Kids road bike for road racing, cyclocross & triathlons
- Dual braking control
- Youth-specific 9-speed gear shifters
Weighing just 8.2kg, the Frog 58 Road Bike is built for speed and performance. Its ultra-lightweight frame helps young riders move faster and cycle longer without strain. Dual braking controls and short-drop handlebars offer easy handling for smaller riders. Two sets of tyres—slick and grippy—make it ready for both road and cyclocross. Built with child-specific components, this bike gives young racers the control they need for competitive cycling or everyday road rides.
Key Features and Benefits:
- Super-lightweight 8.2kg frame: Reduces the effort needed to pedal and steer. Children use less energy to ride, which means they can go further and faster with more control.
- Narrow short-drop child-specific handlebars: Designed to fit smaller shoulders and hands. This improves grip and stability when riding in a road position. Children feel more in control and ride with better confidence.
- Dual braking control: Includes Microshift short-reach levers and auxiliary top-bar levers. These allow braking from multiple positions, making stopping easier and safer.
- Patented Frog cranks: Feature reduced Q-factor and optimized pedal spacing. This ensures efficient pedalling for children’s hip width, boosting comfort and cycling performance.
- Youth-specific 9-speed gear shifters with FrogFit Technology®: Allow smoother gear changes tailored to small hands. Riders shift with ease and maintain speed more effectively.
- Two sets of tyres included (slick and cyclocross): Slick Kenda tyres offer low rolling resistance for road riding, while grippy cyclocross tyres provide traction on rougher ground. This makes the bike versatile across different riding conditions.
- Microshift short-reach brake levers: Designed for smaller hands. Children can brake confidently with reduced hand strain, increasing safety during fast rides.
- Ergonomic slimline children’s saddle: Built for comfort and range of motion. Riders stay balanced and agile during high-energy cycling sessions.
The Frog 58 Road Bike has a lightweight frame that helps cuts down fatigue. The short-drop handlebars and braking system give greater control. The gear setup and crank design improve pedalling power and reduce discomfort. This lets young riders focus on developing their speed, stamina, and skill on the road.
Support your child’s cycling development with a bike that fits and functions like it should. Built for serious young riders, this road bike combines comfort, control, and race-ready components to help them ride at their best.
