ROCKRIDER 100 20-INCH MOUNTAIN BIKE - WHITE

There are two barrel adjusters on each brake, situated on the brake levers. They are used to adjust the tension of the brake cable. Make sure you get the setting right when using the barrel adjuster. (The more the barrel is tightened, the tighter the cable).

This barrel adjuster is located to the rear of the derailleur. It is used to adjust the tension of the derailleur cable. If the chain struggles on climbs, it means the cable is not tight enough. Tighten it by unscrewing the barrel. If the chain does not run smoothly on descents, then the cable is too tight. Turn the barrel to slacken the cable. A quarter turn is often all you need.

The brake cable noodle is a stainless steel part that is used to guide the brake cable into the V-brake calliper. The noodle is set at a specific angle to ensure the cable can slip into position and offer effective braking. It can be replaced if damaged.

A V-brake is comprised of two callipers (one left calliper and one right). They are linked together in the middle, at the brake cable sleeve. 

Pull the brake cable housing out to release the callipers. This will allow you to take the wheel out easily.

The two screws secure the stem to the head tube on the fork.

It's important to adjust the height of the seat post and the handlebar to fit your child's height. The mark indicating the minimum insertion point of the seat post, 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 saddle 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 saddle 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. 

You can test the brakes on your child's mountain bike by taking it by the handlebars and walking with it, 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.

The recommended pressure is always indicated on the tyre sidewall. We recommend inflating your tyres to the pressure indicated on each tyre, This may vary from tyre to tyre. 

You can check that your tyres have enough air in them simply by putting your child in the saddle. With their weight, the tyre should go down ever so slightly.
