Why Kids (& Parents) Love it
Easy to Ride
A low centre of gravity, narrow q-factor (the distance between the pedals) and shorter cranks make it easier to start, stop and balance, while smooth 7-speed Shimano gears help them tackle hills and longer rides with ease.
Lightweight, only 8.3 kg
The base 20 is a trailblazer in lightweight design for kids, weighing only 8.3 kg. This builds confidence through improved manoeuvrability, easier handling, and reduced fatigue for young riders.
Geared up
Smooth shifting 7-speed Shimano gears help them conquer hills and longer rides with confidence.
Safe stopping
Powerful and safe stopping is ensured with high-quality front and rear Tektro V-brakes.
Grows with them
Designed with growing boys and girls in mind, the seat can be easily raised or lowered using the quick-release mechanism.
The handlebars can be rotated to optimise and adjust the reach and height as your child grows.
Long lasting and durable
Built to withstand the Australian outdoors with durable materials like stainless steel spokes with brass spoke-nipples, a fully sealed bottom bracket with steel cups and a semi-integrated threadless headset.
Combined with premium components like Shimano gears, Tektro brakes, Kenda tyres, ProWheel cranks, and a KMC chain, the base 20 is made to last—perfect for passing down to younger siblings or reselling later on.
