Children's bicycle ATTABO KNACK 20" black (ATB-B5I024-BK)

The ATTABO KNACK 20" children's bike is a model designed for young cyclists who want to develop their skills and enjoy outdoor activities. Robust construction, high quality components and thoughtful geometry make riding this bike smooth, comfortable and safe. 

Sturdy frame

The bike's frame is made of aluminium, which ensures low weight and easy manoeuvrability. The 70° head tube angle and 439mm top tube length guarantee stability and predictable movements, which is key for young riders learning to ride with confidence.

Stainless steel fork 

The steel fork effectively absorbs vibrations, which improves riding comfort on rough surfaces. Thanks to its robust construction, the bike will perform well on asphalt as well as on compacted forest or park paths.

Ergonomic handlebar 

The 560 mm wide handlebar with 10° backsweep allows for natural hand positioning, making it easier to control the bike. The 40 mm long aluminium stem with a +7° angle improves the child's position for comfort and stability while riding.

Reliable drivetrain

The drivetrain is based on 114 mm long steel cranks and a 32T front sprocket for a smooth ride and light pedalling. The Shimano MF-TZ500 freewheel with a range of 14-28T allows you to adjust your pace smoothly, while the KMC Z7 chain guarantees high durability and reliable performance.

Lightweight and robust wheels

The bike has 24H aluminium rims and 14G steel spokes for stability and strength. Steel hubs with ball bearings minimise rolling resistance, allowing your child to balance more easily and ride smoothly.
