One of the biggest temptations is to buy a bike your child will 'grow into'. However, this is likely to have the opposite effect and put your child off bikes and cycling altogether! The data obtained during our child specific frame design research has been used to produce a helpful sizing app. Ask in your local store about our FrogFit app to get the best sized bike for your child.
Another common mistake is to purchase a budget bike but these models are often as heavy as the child and leads to frustration at not being able to cycle. Our lightweight bikes are a great confidence booster and can also be used as a balance bike for a taller child by removing the pedals.
Wheel Size: 14" inch
Why buy a Frog 40?
