Kids bikes are safest when you buy from a reputable bike shop and have been assembled by a professional mechanic. We have a huge range of kids bikes including kids mountain bikes, BMX bikes, and balance bikes from Apollo, Radius, Rocket, Merida, and more. Choosing the right colour is important but even more important is choosing the right size. Kids bike sizes refer to the diameter of the wheels, with the most popular sizes being 12 inch, 16 inch, 20 inch & 24 inch. We recommend you visit your local 99 Bikes store for a professional bike fit and sizing, however the general recommendation on kids bikes are: 12inch wheel best for 3-5 years old or 78 to 94 cm tall, 16inch wheel best for 5-7 years old or 84 to 112cm tall, 20inch wheel is best for 7-9 years old or 108 to 129cm tall, and 24inch wheel is best for 9-12 years old or 125 to 148cm tall. The best way to determine correct bike size is to visit a 99 Bikes store.

Balance bikes are a great introduction to riding without the additional complications of pedals. Your little girl or boy will gain confidence and basic balance skills and have a great time while they're at it. These bikes are the perfect start to the world of bikes, all whilst helping your kids gain great balancing ability and set them up for a pedal bike as they build their ability.

We have a great range of girls mountain bikes for sale. Girls bicycles feature slightly different frame designs to provide a greater level of riding comfort for your girl. Our range of girls bikes also feature bright and colourful designs which ensure she'll want to ride it as often as possible.

Our range of boys bikes include wheel sizes ranging from 12 inch to 24 inch which means you’ll be able to find the perfect sized bike for your son. All of our boys bikes are built to the highest standard and we carry only the best brands, all at incredible value.
