Specifically designed for children

The Tektro TKD 68 160 mm double disc brakes provide powerful, progressive braking at the front and rear. The aluminium Tektro brake levers are precise, and easy to hold. Just two fingers are all you need to brake. 3 or 4 sets of 10 dry, intermittent stops are enough to break in your pads. Try to get your brakes adjusted at least once a year.

20 inch wheels

The 27.5" wheels of the ST 120 are tolerant and sturdy, with 19 mm double-walled rims with 28 spokes. Slow down without worrying about obstacles: small rocks, cracks, holes and bumps! Because your first tours will be on dry ground, the Dry 27.5 x 2.0 tyres are most suitable. Their performance is optimised thanks to the rounded central section, whilst the side lugs provide good grip on turns.

Low-rise handlebars for a comfortable ride

The saddle of the ST 120 is welded to prevent any movement of the saddle. And because your comfort is our priority after your safety, we've added an exclusive wider Ergofit saddle with a hammock shape. Easily adjust the height of your saddle with the Flex steel seat post, either 350mm or 400mm long (according to the bike size). Its reduced diameter of 27.2mm provides your seat with natural flexibility, 30% more than a standard solution.
