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. This is why our engineers and designers have designed
a brake lever closer to the handlebars that is easier to hold. 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 callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.


Children won't mistake their gears thanks to the grip shifter that changes speed sequentially. This ultra flexible system means the speed is changed one at a time, limiting the chance of the chain coming off!

Additional fittings

The front and rear mudguards protect against splashes when cycling.
A pannier rack allows you to carry small items with you. And when you take a break, the stand makes it easy to park the bike.
The bike is fully equipped for cycling on public roads, day or night: dynamo-powered LED lights, bell, wheel reflectors, tyres with reflective strips.

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 lower frame geometry makes it easy to get on and off the bike.
The frame is made from steel for strength.

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 protective guards

To prevent children from becoming dirty, this bike is equipped with a guard that protects the chain and chainwheel. The design of the guard will inspire your imagination!
