Product Overview

The Frog Track 70 is a lightweight 26 inch junior track racing bike designed for young riders aged approximately 11 to 14 years who are progressing in velodrome or grass track cycling.

 

It features a stiff aluminium frame with aerodynamic teardrop tubing and track-specific geometry to support efficient pedalling, confident handling, and controlled speed. Patented short 140mm Frog cranks aid smooth power transfer for younger riders, while toe-clip pedals and a quick-release seat post support secure positioning and ongoing height adjustments as they grow.

 

This model is suitable for riders with an inside leg measurement of 67 to 84 cm and offers a stable platform for juniors developing technique, increasing riding confidence, and practicing race skills.
