Frog 78 8-Speed Bike
Lightweight, strong, comfortable and kids love the way it looks!
Fits: 13+ yrs with a minimum inseam of 78 cm (30.5")
The Frog 78 features a strong, high quality, lightweight frame, designed specifically for your child's size. The adjustable Tektro brakes inspire confidence and are easy to adjust for the reach of small hands. Features an 8-speed Shimano easy-change thumb shifters and an 8 speed cassette hub. Easily adjusted saddle height and now a shorter crank length of 127mm. Comes with 2 sets of Kenda tires: a hybrid tire and a more knobby off-road tire.
Frog bikes are easier to pedal due to a unique crank design from the renowned bicycle engineer Dimitris Katsanis (of Team GB Olympic fame). The new design reduces the Q-factor (the space between the pedals), allowing children to push more directly down when cycling, so converting more of their energy into motion. Only Frog applies this level of rigour to the design of kids’ bikes.
Comes with a bell, reflectors and mudguards as standard.
Free 5 year warranty available on the frame and forks, 2 years on all other parts.
