Frog Bikes 78 2021 26 Inch Kids Hybrid Bike Red

5 out of 5 Customer Rating

The Details

Stepping up the frame size, the Frog Bikes 78 is suited for young riders aged 13+ with a minimum inside leg of 78cm 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.

The Frog 78 offers total independence, with wide tyres and a sturdy frame it is perfect for doing a paper round on the road or flying down forest trails with friends at the weekend. You also have the option to attach a pannier rack to the frame for transporting school books and sports kit.

  • Lightweight but sturdy Frame making the bike easy to ride and carryTektro brakes with easy to reach brake levers.
  • Better braking and speed control means improved confidence for young riders
  • FrogFitTechnology® youth-specific 8-speed gear shifters with short lever travel and ultraslick gear cabling makes changing gear and undulating rides a breeze
  • 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
  • Quick-release seat post for easy height adjustment
  • Free 5 year warranty on frame and forks
  • Reflectors, mudguard and bell included

Our Verdict

Building on the success of the Frog 72, the new Frog Bikes 78 is part of their new Push The Limits range - more of an adult riding experience with youth friendly geometry and quality.
