We've designed this 20-inch hybrid bike for children aged six to eight years (120 to 135cm) who want to cycle in urban parks or on pathways. It's robust and easy to use - it has just one speed and brake levers adapted to little people's hands - and a really fun choice for their first outing on two wheels.
  • Single speed
  • The brake levers are specifically designed for small hands
  • Best on flat terrain

Technical Information

Why have we created a brake lever specifically for children?

Because children have smaller hands than adults, it's not always easy for them to reach the brake lever. That's why our engineers and designers have designed them to be closer to the handlebars for easier grip. The brakes are now in reach of little hands!

V-brake brake pads: Controlled braking

Two V-Brake pads for effective braking. These brakes are composed of two callipers that can exert varying degrees of pressure on the rim to slow the bike or stop the wheels from spinning.


This single-speed bike is simple and effective on flat terrain.

Comfortable cycling position

With its semi-raised handlebars, it has a comfortable riding position. The handlebars and stem are welded in a single piece to make adjustment easier (height only).

Lowered frame: easy to mount!

The lowered frame geometry makes it easier to get on and off the bike. The robust frame is made from steel.

A reinforced, ergonomic saddle

A saddle carefully designed to fit a child's build. It is equipped with a plastic cover at the back (a bumper) to protect from any impact.

With a protective housing and anti-derailment system

The chainwheel guard offers added safety by reducing the risk of injury on the chainwheel. The chainring is covered with a second inner chainguard to prevent any chance of derailing.

Wheel/tyre information

A hybrid tyre suitable for both roads and trails.
20-inch 1.7 to 2.2 section inner tube with Schrader valve.
