B'TWIN 4 TO 6 YEARS 16" BIKE 500 SPY HERO GIRL

The recommended pressure is always written on the side of each tyre. We recommend inflating the tyres to the pressure indicated on the tyre sidewall. This may vary between tyres. 

To check if the tyre is correctly inflated, simply squeeze it between your fingers: it should be firm while yielding a little under your fingers. 

Roll the 16" bike forwards by the handlebar. Press the brake lever. The rear wheel should stop moving following this action.

 

If you notice that the brake is not working correctly, please try the following: There is an adjustment wheel in front of the brake lever. You'll see a "+" and a "-". If you turn the wheel clockwise (towards the "+"), this will tighten the brake (= stronger braking). If you turn the adjustment wheel anti-clockwise (towards the "-"), that will loosen the brake (= weaker braking).

 

It's important to regularly check the brakes are correctly adjusted.

It's important to adjust the height of the saddle and handlebar to suit the child. The minimum insertion mark on the seat post and handlebar should never be visible for safety reasons (ensure this mark is never exceeded).  

To check the correct saddle height, when sitting on the saddle, both of the child's forefeet should be touching the ground.

Correctly adjusted, this should allow the child to easily get on and off their bike, and prevent their knees from rising too high when pedalling. 

If you notice that the bike is dirty after a few rides (mud, rain, dust, etc.), give it a good clean.   If there is dust: simply use a dry cloth to clean it. If there is more persistent mud or other dirt, you can clean it with a bucket of hot water and a sponge (or wet cloth) with soap or bike shampoo. You can then clean the dirty parts of the bike (frame, fork, handlebar, wheels).   DID YOU KNOW?   Avoid spraying the bike with the hose: some components won't take it kindly!   When you've finished, simply wipe it dry with a cloth to prevent rust.Take the opportunity to check the tightness of the clamps and wheels: are they tight enough? If not, tighten them using a spanner.

We recommend storing the 16" bike in a dry place.  It's important to ensure that it stays dry.

Wash using a wet cloth and soap or washing up liquid, then wipe with a dry cloth!

You can use an all in one product to loosen, clean, lubricate and protect the chain on the child's bike (product available in Decathlon stores). It's a very practical product. To grease the chain, turn it using the pedal and spray along the length of the chain.  Allow to dry. 

Why remove the chainguard from the bike? It's a must if you want to access the rear wheel to change the inner tube for example. 

 

REAR WHEEL:

 

STEP 1: Face the right-hand side of the bike. Use a 15mm spanner to unscrew the right pedal (turning anti-clockwise).

Do the same for the other side: face the left-hand side of the bike, and use a 15mm spanner to unscrew the left pedal (turning clockwise).

 

STEP 2: Use a flathead screwdriver, remove the elastomer ring located above the chainguard, then move it up the seat post. You can hook it onto the seat clamp collar to prevent it from sliding down.

Then, remove the second ring located underneath the chainguard.

 

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

Then, remove the flat washer. Try to position the crank facing forwards (see photo) to have easier access to the chainguard. Then, you can remove the chainguard. To do this, hold the back of the chainguard and remove it completely.   Do the same for the other side.

 

STEP 4: Unscrew the wheel nut using a 14mm spanner. Then, remove the nut and the grooved washer (the grooved washer has grooves on the top).

 

STEP 5:  Push the rear wheel forwards to loosen the chain. Then remove the chain. Remove the wheel from its position by pulling it backwards. (remember, it remains attached to the bike through the drum brake). Remove the flat washer from the right-hand side.

 

THE TYRE AND INNER TUBE ARE NOW ACCESSIBLE! 

You can now change the tyre or repair a puncture to the inner tube.
