Children's bicycle ATTABO KNACK 20" blue (ATB-B5I025-BL)
ATTABO KNACK 20" is a bike designed for children age 5-9 and height 110-135 cm who want to improve their skills and enjoy outdoor activities. Thanks to its solid construction, lightweight frame and high-quality components, this model provides stability, safety and comfort on both urban paths and more demanding routes.
Sturdy frame - stability and control
The bike is stable and easy to manoeuvre, making it easy to learn to ride smoothly and allow for confident handling. This is due to the aluminium frame, which is characterised by low weight and high resistance to mechanical damage. The head tube angle of 70° and top tube length of 439 mm further enhance control of the bike, ensuring predictable responses when riding.
Stainless steel fork - cushioning and durability
Riding comfort on rough surfaces is enhanced thanks to the steel fork, which effectively absorbs vibrations and provides greater stability. The robust construction makes the bike durable and resistant to intensive use, making it suitable for both asphalt and paved forest paths.
Ergonomic handlebar - precise control
The child can control the bike more easily and maintain a stable position thanks to the 560 mm wide handlebar with 10° backsweep. The natural positioning of the hands improves riding comfort, while the aluminium stem with a length of 40 mm and an angle of +7° supports correct posture, which reduces fatigue on longer rides.
Reliable drive - smooth and efficient ride
The pedalling is light and smooth, allowing easy acceleration and a comfortable ride over varied terrain. This is the result of the 114mm steel cranks, 32T front sprocket and Shimano MF-TZ500 freewheel with a 14-28T range. The KMC Z7 chain further increases the durability and reliability of the entire drivetrain.
Lightweight and robust wheels - stability and smoothness of ride
The bike moves smoothly and remains stable even on uneven surfaces. This is due to the use of aluminium 24H rims and 14G steel spokes, which provide adequate strength. Stainless steel hubs with ball bearings reduce rolling resistance, making riding less of an effort.
