It’s kitted out with high-spec, age-specific components, designed for ease and comfort to help them build confidence and progress like a pro! They can experience smoother downhill control with the hydraulic disc brakes and impactful suspension forks, and tackle uphill climbs like a champ, thanks to the ultra-lightweight aluminium, child-specific frames. 

This agile junior mountain bike also features an oversized handlebar and stem to reduce flex, giving your little shredder better control. It also comes with Kenda MTB tyres for maximum grip and comfort in all weather conditions and on all terrains. And our patented Frog cranks let kids pedal more efficiently, keeping them fast, nimble, and ahead of the game.

Custom kids’ mountain bike forks

For young lighter riders, we created custom suspension forks to ensure that our Push the Limits mountain bikes perform perfectly regardless of a rider’s weight. Learn more about how our forks are designed to work with a child's weight

Get sized for cycling success

The Frog MTB 72 mountain bike is suitable for 13+ years with a recommended inside leg measurement of 66cm-85cm.

One of the biggest temptations is to buy a child's first bike that they will grow into. However, this will likely have the opposite effect and put your child off bikes and cycling altogether! Another common mistake is to purchase a budget kids' bike but these models are often as heavy as a child which can lead to frustration at not being able to cycle. That’s why Frog bikes are lightweight and designed to specifically accommodate the anatomy of children.
