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.

* Minimum inseam measurement for a child who is large enough to ride this bike. Beginner Riders must reach the ground comfortably and flat footed while straddling the seat, meaning they require a larger minimum inseam. Experienced Riders will be more comfortable extending to their tip toes when straddling the seat. See How to Measure Your Child's Inseam.
† Standover Height is measured from the top of the top tube to the ground, rising directly from the front of the chainring.
