Base Bikes base 20 | 20 inch bike

Low centre of gravity (easier to balance), ultra-light (easier to push off and control), and 7-speed smooth Shimano gears, are just a few reasons the base 20 is the easiest bike to ride.

The base 20 is a trailblazer in lightweight design for kids, weighing only 8.5kg. This builds confidence through improved manoeuvrability, easier handling, and reduced fatigue for young riders.

Smooth shifting 7-speed Shimano gears help them conquer hills and longer rides with confidence.

Powerful and safe stopping is ensured with high-quality front and rear Tektro V-brakes.

Designed with growing boys and girls in mind, the seat is fully adjustable and can be easily raised or lowered using the quick-release mechanism. Like an adult bike, it also allows forward and backward adjustments and can be tilted.

The handlebars can be rotated to optimise and adjust the reach and height as your child grows.

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 tires, ProWheel cranks, and a KMC chain, the base 20 is made to last—perfect for passing down to younger siblings or reselling later on.

Sizing

The most reliable way to pick the right size bike is to measure your child's inseam and consult the table below. Although less reliable than the inseam, you can use your child's height or age.

Base Bikes have put together a detailed guide with considerations and tips to help you choose the perfect bike size for your child. Check it out for more in-depth information!

*For tentative riders, riders brand new to pedal bikes or if you are intending to use the pedal bike in balance bike mode initially (without the pedals), an inseam of 3cm more than minimum listed will offer more comfort and confidence.
