Product Overview

The Frog Track 58 is a lightweight 20 inch junior track bike designed for young riders aged six to seven years old who are beginning their journey into velodrome or grass track cycling.

 

With a child specific geometry, aerodynamic teardrop frame tubes, and patented short Frog cranks, it supports efficient pedalling and stable handling. The stiff aluminium frame, Kenda track tyres, and single speed setup are designed to deliver smooth, controlled acceleration and secure footing during training and early races.

At just 6.78 kilograms, this junior track bike helps small riders build confidence, develop cycling technique, and experience track riding in a safe and structured way. It is suitable for children with an inside leg measurement of fifty two to sixty three centimetres.

 

Please note that this bike is designed for track use only and does not include brakes, a bell, or reflectors. A front brake kit can be purchased separately if required.
