Prevelo Alpha Three blue
The Prevelpo Alpha Three is a lightweight, 20" geared bike designed for confident young riders ages 5 to 9. Built for adventures on pavement, paths, and light trails, it delivers refined performance, intuitive handling, and a fit that respects growing riders’ proportions.
It features a lightweight triple-butted 6061 series aluminium frame with low centre of gravity, kid-specific geometry, internally-routed cables, and 3D forged dropouts. It is also dropper post compatible.
Other highlights include Promax hydraulic disc brakes, a Microshift Acolyte 8-speed gear system with super-wide 11-38T gear range, and durable double-wall tubeless-ready rims.
Weighing just 7.65kg, the Alpha Three blends low weight with high capability - ready for kids who want to ride further, shift smarter, and stop with confidence.

Hill-conquering gear range
The Microshift Acolyte super-short derailleur allows the Alpha Series bikes to use an 11-38T cassette, giving 90% more gear range than other comparable bikes. The clutched cage helps keep the chain from dropping over even the roughest terrain.

Promax hydraulic disc brakes
Promax hydraulic disc brakes provide young riders with smooth, consistent, reliable stopping power. Whether navigating steep descents or threading through technical trails, these brakes offer excellent modulation and control, helping kids ride with greater confidence and composure. Designed to perform in a wide range of conditions, Promax hydraulic disc brakes inspire trust in both riders and parents, by delivering powerful braking performance when it matters most.

Double-wall tubeless-ready rims
Durable double-wall rims provide a strong, stable platform for young riders tackling rough terrain. Tubeless-ready design allows for lower tyre pressures, better traction, and fewer flats - ideal for confident riding on trails and beyond!

Kid-centric control centre and integrated handlebar
Short stems, handlebars sized to match shoulder width, easy-to-reach brake levers, and a kid-optimised shifter all come together to give young riders confident control of their bike. The cockpit is thoughtfully designed with an integrated handlebar and stem for a clean, solid setup that reduces weight and potential maintenance points. Recessed bolts minimise snags and scrapes, while the overall layout keeps controls within comfortable reach. Every detail is dialled to help kids stay focused on the ride, not the equipment.

Kid-friendly shifting
Microshift builds some of the most thoughtfully engineered shifters for young riders. With compact, easy-to-reach triggers and exceptionally light actuation, this system is designed specifically with smaller hands in mind. The result is a smooth, intuitive shifting experience that empowers kids to ride with confidence and control. By prioritising ergonomics and usability for youth riders, Microshift delivers a drivetrain interface that feels natural from the very first ride - no awkward reaches, no excessive force, just seamless gear changes tailored to growing cyclists.

Protected flat-mount rear caliper
A flat-mount rear brake caliper is positioned snugly between the seat stay and chain stay, shielding it from trail hazards and accidental bumps. This low-profile placement keeps the caliper protected without compromising performance, delivering reliable braking while preserving the clean lines of the frame.
