B'TWIN ROBOT 500 16" BIKE FOR KIDS AGED 4-6

2020

Ready to ride? We designed this 16" bike for children aged 4½ to 6 (105 cm to 120 cm tall) learning to ride a bike like the big kids.

A chainguard, mudguard and stand let your child enjoy their first rides without getting dirty or damaging their bike. Compatible 16" stabilisers available if necessary.

First use

How to adjust the saddle and handlebar height

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.

How to check that the v-brakes are correctly adjusted

You can test the brakes on your child's bike by taking it by the handlebars and pulling the right lever to test the rear brake and the left to test the front.The wheels should stop moving when the respective lever is pulled. The brake pads should not rub against the sides of the rim when the brakes are not engaged.

 

Here's what to do if you notice that the braking isn't smooth or the wheels rub on the brakes: There is a barrel adjuster in front of the brake lever. Turn the barrel in a clockwise direction to tighten the brake for sharper braking. Turn the barrel in an anti-clockwise direction to loosen the brake for less sharp braking and to move the brake pads away from the rim. 

 

It's important to check your brakes regularly.

Inflating the bike tyres to the correct pressure 

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. 

Maintaining your 16" kids' bike

Cleaning and greasing the chain

You can use an "all-in-one" type product (available at Decathlon stores) to unjam, clean, lubricate and protect your child's bike. 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 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.

How to clean the handles on your child's bike

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

How to store your bike

We recommend storing your 16" bike in a dry place. It is important for the bike to not be exposed to damp air.

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

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.
