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.
The data obtained during our child-specific frame design research has helped us create a helpful kids’ bike sizing app. View our bike sizing guide to discover the best-sized bike for your child or alternatively speak to one of our local stockists about our children’s bike range.
Please be aware! 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.
