Why Frog MTB 72?
With the awesome Frog MTB 72 kids mountain bike, 13+ year old off-road adventurers will be able to hit the trails, pumptracks and streets in style. The lightweight aluminium mountain bike weighs just 11.5kg and features hydraulic disc brakes, air suspension forks and a 9-speed drivetrain to provide the ultimate off-road ride.
Part of our Push The Limits range, the Frog MTB 72 Junior Mountain Bike is ideal for kids to make trail riding fun and easy. It features top-of-the-line age-specific components designed for ease and comfort to help them build confidence and progress like a pro! They can experience smoother downhill handling with hydraulic disc brakes and impressive suspension forks, and tackle climbs like a champ thanks to ultra-lightweight aluminum frames designed for kids.
This agile junior mountain bike also has oversized handlebars and stem to reduce flex, giving your little shredder better control. It also comes with Kenda MTB tires for maximum grip and comfort in all weather and on all terrain. And our patented Frog cranks allow kids to pedal more efficiently, making them fast, nimble and ahead of the game.

Get sized for success on the bike
The Frog MTB 72 mountain bike is suitable for children 13 years and older with a recommended inside leg length of 66-85cm.
One of the biggest temptations is to buy your child the first bike they grow into. However, this is likely to backfire and put your child off cycling and biking altogether! Another common mistake is to buy a cheap children's bike, but these models are often as heavy as the child, which can lead to frustration at not being able to cycle. That's why Frog bikes are lightweight and designed to adapt to children's anatomy.
The data collected during our research into child-specific frame design helped us create a useful app for sizing bikes for children. Check out our bike size guide to find the best bike for your child, or alternatively speak to one of our local dealers about our range of kids bikes.
