REF: 8402832



1..2..3 pedal! We designed this 14" bike to help children ages 3 to 5 and measuring 90 to 105 cm tall, to learn to pedal and ride a bike like big boys and girls.

It has a step-through design and training wheels that allow your child to learn to ride at his or her own pace. It is equipped with a chain guard and mudguards to prevent rubbing or getting dirty from the chain or wheels.

First use

How to adjust the seat and handlebar height before your child's first ride

It's important to adjust the height of the seat tube and the handlebar to fit your child's height. The mark indicating the minimum insertion point of the seat tube, or the handlebar, into the frame, should never be visible for safety reasons (make sure that neither the seat post nor the handlebar extend past this minimum insertion level).

To determine the correct seat height: sit your child on the bike with one heel resting on the pedal with the crank turned so that the pedal is at its lowest position. The seat height is correct when the child's leg is extended while in this position. Also while seated, check that the child can touch the ground with their toes.

How to check that the brakes are correctly adjusted

Walk the 14" bike while holding the handlebar. Then squeeze the brake lever. This action should stop the back wheel from turning.


If you observe that the braking action is not effective, do the following: There is a knob located in front of the brake lever with a "+" and a "-". Turning this knob clockwise (towards the "+") will tighten the brake (stronger braking action). Turning the knob counter-clockwise (towards the "-") will loosen the brake (weaker braking action).


It's important to regularly check that the brake is properly adjusted.

How to correctly inflate the tyres on your 14" bike

The recommended tyre pressure is always indicated on the side of each of your bike's tyres. We recommend inflating your tyres to the pressure indicated on each tyre, which may vary depending on the type of tyre.

To check whether the tyre is sufficiently inflated, squeeze it between your fingers. It should be firm while still yielding a bit when pressed.

How to remove the training wheels

Removing the training wheels on your 14" bike is easy.

Simply unscrew the knob on either side of the bike. This can be done without tools. Unscrew the knob by hand by turning it counter-clockwise. Then, remove the small wheels on either side.

You're done!

It's the beginning of a whole new two-wheeled adventure! :-) 



Caring for your child's 14" bike

How to grease your child's bike chain

You can use an "all in one" type product to degrease, clean, lubricate and protect your child's bike (available in Decathlon stores). It's a very handy product! To grease the chain, turn the pedals while briefly spraying the chain along its entire length as it moves.  Let it dry for a few minutes before use. 

How to wash your child's bike

If you notice that your child's bike is dirty after a few rides (mud, rain, dust, etc.), it's a good idea to take a few minutes to get it clean again as needed.   If it's just dusty, cleaning is easy: simply wipe it down with a dry cloth. If it has mud on it or dirt that won't come off so easily, you can clean it with hot water, bike soap or shampoo, and a sponge (or wet rag). Wipe down the dirty parts of the bike (frame, fork, handlebar, wheels).   TIP: It's best to avoid hosing down your child's bike with a jet of water as this can damage some components.   When you've finished, simply dry it off with a cloth to prevent rust.You should also use the occasion to check the wheels and clamps: are they on tightly? If not, tighten them using a wrench.

How to remove (and replace) the chainguard on a 14" child's bike in order to replace an inner tube

Why remove the chainguard on your 14" bike? This is an essential step in order to access the rear wheel when you need to replace the inner tube, for example.



STEP 1: Stand facing the right side of the bike. Using a 15 mm spanner, unscrew the right pedal (turn the spanner counter-clockwise).

Repeat on the other side: facing the left side of the bike, use a 15 mm spanner to unscrew the left pedal (turn spanner clockwise).


STEP 2: Using a flat head screwdriver, remove the rubber ring above the chainguard and pull it up along the seat post. You can hook it onto the seat post clamp to keep it from falling back down.

Next, remove the second ring, which is found under the chainguard.


STEP 3: unscrew the nut holding the chainguard (located on the rear wheel axle) using a 15 mm spanner (from each side of the wheel).

Next, remove the washer. Be sure to position the crank towards the front (see photo) so that you can remove the chainguard more easily. You can now remove the chainguard. Grasp the back of the chainguard and pull it off. Repeat on the other side.


STEP 4: unscrew the nut holding the wheel using a 14 mm spanner. Next, remove the nut and the washer (this washer is grooved rather than flat).


STEP 5: push the rear wheel forward to loosen the chain. Remove the chain. Separate the wheel from the frame by pulling it towards the back (note that the brake pads will keep it connected to the bike). Remove the washer from the right side.



You can now change the tyre if needed or repair a punctured inner tube.
