The Details

Building on the success of the Frog 72, the new Frog Bikes 78 is part of their new Push The Limits range that offers a more adult riding experience with the youth friendly geometry and quality you can expect from a Frog.

Steeping up the frame size, the Frog Bikes 78 is suited for young riders aged 13+ and is the true stop gap between their childhood bikes and a full sized adult bike. Crafted from double butted aluminium the Frog Bikes 78 is exceptionally lightweight at just 10 kilos making it a joy to ride.

Reliable 8 speed groupset components provide a solid range of gears while the Tektro brakes with easy reach levers offer all the control they need both on and off road. This gives confident stopping power and smooth shifting without creating a difficult to use or unnecessarily complicated cockpit.

  • Lightweight aluminium frame
  • 5 year guarantee
  • Selection of colours available

Our Verdict

The Frog 78 is part of the 'push the limits' range from Frog. The same lightweight bikes you expect from Frog, but designed for older kids.

Frog Kids Bikes Size Guide

Frog bikes are typically sized by the inside leg length rather than age, as this is the most reliable way of getting the right size of bike for each child. 

We recommend trying your size at one of our store, who will then also build it for you and ensure the fit is right for your child.
