With this city bike, kids will enjoy more upright leisurely riding position, owing to longer head tube & raised slightly swept handlebar. It is equipped with 8-speed derailleur gears that provide more range for moderate speeds, & a floating chain glider to prevent clothing from getting stuck & chain from getting soiled.

A big temptation is to buy a child's bike they will grow into. However, this will have the opposite effect & put your child off bikes & cycling altogether! Another common mistake is to purchase budget kids' bike, these models are often as heavy as a child which can lead to frustration at not being able to cycle. Frog bikes are lightweight & designed to specifically accommodate the anatomy of children.

Available colors*: Teal, Pink, Black

*Actual colors may vary. This is due to the fact that every computer monitor has a different capability to display colors and that everyone sees these colors differently.

CAUTION! The kickstand is designed solely to support the weight of the bicycle. Avoid sitting on bicycle when kickstand is engaged to prevent potential damage to kickstand, bike frame or risk of injury.
