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.
Product Details

Shimano derailleur
The ATTABO KNACK 20" model is equipped with a Shimano Altus 7s derailleur, which allows the gearing to be easily adapted to the terrain. Thanks to the seven-speed drivetrain, your child can comfortably tackle both uphill and fast, flat sections.

Secure and comfortable grip
The bike is equipped with 130 mm long rubber grips, which improve riding comfort and provide a firm grip on the handlebars. Their non-slip surface increases safety, allowing better control of the bike even on longer rides.

Kenda tyres - good grip
The ATTABO KNACK 20" model is equipped with 20 x 1.75" Kenda K879 tyres, which provide adequate grip on various surfaces. Thanks to the well-matched tread, the bike will work well both in the city and on paved off-road paths.

Comfortable and functional saddle

Effective V-brakes
The bike is equipped with Power V-brake VBR-227A brakes, which provide effective and precise braking. The Power MBL-421PA handles have been tailored to suit children's hands, making it easy to stop the bike quickly when needed.
