Frog 73 8-Speed Kids Bike (26")
Lightweight, strong, comfortable and kids love the way it looks!
Fits: 12-14 yrs with a minimum inseam of 73 cm (28.75")
The Frog 73 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.
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.

Assembly
All Frog 73 bikes arrive 90% assembled. All you need to do is install the pedals, seat post, handlebars and front wheel. If you decide you want the optional mud guards on your bike, these will need to be installed also.
Our professional bike technician looks over every bike before it ships and switches the hand brakes to be standard for the US (rear on the right, front on the left).

United StatesGood but a couple of improvements needed
Overall this is a great bike. The frame is light, and there are enough gears for my daughter. I do feel the brakes are a weak link on the bike. Also why no kick stand included? It comes with mudguards which are of no use to the majority of users, but doesn't come with a kickstand. Strange choice.
