Product Overview

The Frog City 53 is a twenty inch urban bike designed for children aged approximately five to seven years. With an easy step through frame, upright riding position and smooth eight gear system, it supports confident riding for school journeys, park routes and neighbourhood paths. The design focuses on comfort, visibility and stability, offering young riders a practical introduction to city cycling. Suitable for riders with an inside leg measurement of forty nine to sixty five centimetres.

 

The Frog City 53 is made for short to medium daily rides in town and residential areas. A lightweight aluminium frame helps children control the bike easily and mount or stop with confidence. The upright bar position supports clear visibility and relaxed posture during slower city riding.

 

This model includes eight gears suited to gentle inclines and moderate riding speeds. Frog specific cranks assist smoother pedalling, and easy reach brake levers provide accessible stopping control. Low rolling resistance tyres are designed for pavements, cycle paths and roads.

Useful urban features, including mudguards, kickstand and rear pannier rack, help children carry everyday items comfortably and keep clothing clean.
