Choosing the right bike for a 7–8 year old is key to helping them enjoy cycling safely and confidently. 20-inch kids bikes are the ideal size for children in this age range, offering a balance of lightweight design, safety, and performance. Whether your child is learning to ride independently or ready for their first geared bike, our selection of 20-inch bikes is designed to inspire a love of cycling from the very first ride.
Why a 20-Inch Bike is Perfect for 7–8 Year Olds
A correctly sized bike ensures safety, comfort, and control. Most children aged 7–8 years fit 20-inch wheels, generally corresponding to heights between 115–130 cm. Always check your child’s inside leg to ensure the seat height allows them to place their feet firmly on the ground, which helps them ride confidently.
