Children's Bike Academy S-Grade Trail 4 R – 20" is designed for young cyclists aged approximately 6 to 8 years old (height around 115–130 cm) who are looking for a quality and reliable machine for trail riding.
The bike frame is made from lightweight aluminum and features a ThruAxle (12×142 mm), providing higher stiffness and precision while riding.
The fork is rigid, contributing to lower weight and easy maintenance.
The Shimano set with 9 speeds and short-reach levers is designed to be easily operable for children's hands.
Shimano BR-MT410 brakes provide strong and reliable braking performance even in wet conditions or on steep descents.
The total weight of the bike is approximately 9.6 kg, which is very favorable for this type of bike and contributes to better maneuverability.
The frame has a load capacity of up to 70 kg, meaning the bike can handle not only the rider but also a backpack or additional gear.
