Frog Hybrid 53 Lightweight Kids Bike for Ages 5-7 Years in Green

Season:2024

Brand:Frog Bikes

Code:L-FH53-GRE

The Frog 53 is a bike that will inspire your child to ride. From the lightweight child-specific frame that is easy for them to handle and manoeuvre, to the brakes that are specifically designed for small hands to grab, all confidence enhancing features that will encourage your little bike rider to jump at every opportunity to get out on their bike exploring.

The Frog 53 has been carefully designed to help maximise the lifetime of the bike for a growing child meaning fewer bike changes as they grow. This model will cover growth from 5 to 8 years with an average inside leg of 53cm and is the ideal multi-purpose bike for family fun and leisure riding.

The handlebars can be lowered or raised within a range of 40mm and adjusting the seat height is easy to do at home with the quick release system. This means a Frog Bike will grow with your child making it a great investment.

The Frog 53 also offers a lower bottom bracket position (the frame section between the pedals) to ensure a safer riding position with feet closer to the ground, whilst allowing for a greater leg-length range to be accommodated. An additional 10mm spacer is placed above the handlebar stem to give the option to raise the handlebars higher as your child grows.

Designed and built in Great Britain, Frog's hybrid bikes are perfect for roads, pavements, towpaths and forest trails. They come with mudguards and the option to attach a pannier rack to the frame, for ease of transporting school books and sports kits.

Wheel Size: 20 inch
Age Range: 5-8 Years with an average inside leg of 53cm
