The Frog 78 26" wheel kids’ hybrid bike is the ideal multi-purpose geared bike for 13-year-olds and upwards with a recommended inside leg of 72cm to 88cm.

This bike model is part of Frog's 'Push The Limits' range for older riders.  With 'Push The Limits' Frog decals, children can grow with Frog bikes all the way to adolescence.  The Frog 78 offers total independence, with a sturdy, yet lightweight aluminium frame and fork set, knobbly Kenda Small Block Eight hybrid MTB tyres and an 8-speed gear system.

The handlebars can be lowered or raised within a range of 38mm 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.

Made in the UK at the Frog Bikes factory in South Wales, Frog bikes are perfect for roads, pavements, towpaths and forest trails. The Frog 78 comes with mudguards as standard and has the option to attach a pannier rack to the frame for transporting school books and sports kits.

FrogFitTechnology® youth-specific 8-speed gear shifter with short lever travel and ultraslick cabling make changing gear and undulating rides a breeze.  In addition, patented Frog cranks maintain a low Q-Factor (the distance between the pedals) for easier pedalling.  A reduced distance between the pedals allows for maximum leverage on the pedals increasing efficiency and speed.

Frog is so proud and confident of the quality of their bikes that they offer a free 5-year warranty on the frame and forks.
