Key Features

  • Lightweight but sturdy Frame
  • Tektro brakes with small easy to reach brake lever
  • Patented Frog cranks for easier pedalling
  • Free 5 year warranty on frame and forks
  • Reflectors, mudguard and bell included

Frog Bike Sizing

  • An example of their original approach, rather than numbering their kids' bikes by wheel size, Frog size their bikes by inside leg measurement. Hence the Frog 40 is recommended for children with a minimum inside leg measurement of 40cm.
  • This corresponds with other manufacturers' 14 inch wheel kids' bikes, so the Frog 40 would make a great present for children from 3/4 year old.
  • It comes with a long aluminium seatpost with a quick release seat binder to make it easy to adjust the saddle as the child grows all the way up to around 6 or 7.

Faster Wheels
Another original detail is that the Frog 40 comes with lightweight alloy wheels fitted with good quality Kenda 14 x 1.75 inch hybrid tyres which will be easier rolling than the 14 x 2 inch knobbly mountain bike tyres you'll find on most of their competitors' bikes. Skinnier tyres make a Frog bike easier to accelerate and hence more fun to ride much of the time.

Choice of Colours
Technical attributes aside, this is no ugly frog. Frog bikes look good, so your child should be really proud to own one. To help ensure they delight, Frog bikes are available in a choice of colours.
