Looking for the perfect kids' mountain bike for trails?
The Frog MTB 69 is a premium 26-inch kids' mountain bike designed for riders aged 10 to 13 who are ready to take on challenging off-road trails. Built for speed, control, and durability, it features a lightweight aluminium frame, wide 2.2" Kenda AMRAK tyres for exceptional grip, and a responsive RST F1RST suspension fork with 15mm Thru Axle hub for a smoother, more stable ride over rough ground. 160mm hydraulic disc brakes provide precise stopping power in all weather, while the youth-specific geometry, short stem, and wide handlebars deliver confident handling on woodland paths, rocky climbs, and fast descents. Equipped with a 9-speed Microshift drivetrain and wide-range 11–46T cassette, this kids' MTB makes steep climbs easier and shifting smoother, so young riders can focus on the adventure ahead.
A mountain bike designed to adapt to your child
The Frog MTB 69 kids' mountain bike grows with your rider, thanks to its adjustable handlebar height and quick, tool-free seat post changes. This ensures a proper riding position over time, giving them more control, better comfort, and the confidence to take on tougher rides. The Frog MTB 69 is suitable for children with an inside leg measurement of 65-83cm.

Optimised for junior trail riders
Every part of this bike has been chosen for young mountain bikers ready to explore varied off-road terrain. The Frog MTB 69's compact frame geometry, short stem, and wide handlebars deliver direct, responsive handling, ideal for learning more advanced riding techniques.

Lightweight, durable and easy to handle
Weighing 12.91kg, this aluminium-framed mountain bike is both light enough for easy climbing and durable enough to withstand the knocks of regular trail riding. The well-balanced weight means kids can ride further, climb higher, and descend with confidence. The pedals are made from durable rice husks, using 50% less plastic without compromising strength, making the bike both eco-friendly and robust.

Powerful hydraulic disc brakes
With 160mm hydraulic disc brakes on both wheels, the Frog MTB 69 26-inch kids' mountain bike provides powerful, reliable stopping whether in the mud, on loose gravel, or heading downhill. Riders can count on consistent control no matter the weather or trail conditions.

Smooth gear-shifting for any climb
The 9-speed Microshift drivetrain gives plenty of range for tackling steep inclines and varied surfaces. The clutch derailleur keeps the chain steady over rough ground, and the shifters are designed to suit smaller hands for effortless gear changes.

Superior grip and comfort on any terrain
Wide 2.2" Kenda AMRAK tyres deliver the traction needed for wet routes, loose dirt, and rocky paths, while the RST F1RST suspension fork with 15mm Thru Axle hub helps absorb bumps to keep the ride stable and enjoyable. To keep the fork performing at its best, regular servicing is recommended, especially for riders who love to push their limits.
