A roadworthy bike When you ride your bike on the road, it is important that your bike is roadworthy. When is a bike roadworthy and how can you check? Let's find out together with Mio. Let's take a closer look at Mio's bike together. Do you know what these two parts of the bike are called?
These are your bike's wheels. They are secured with screws. Make sure that the screws are really tight. Ask an adult for help.
The wheels include the TIRES. They should have enough tread so that you have enough grip while riding. The tires must also have enough air. To check the air in your tire, you can simply try to squeeze the tire. If your tire has enough air, then it can only be squeezed slightly. What are the names of these parts?
These are spoke reflectors. Sometimes they are also called cat's eyes. They should be attached to both wheels. On some bikes, reflectors are also directly on the tires When it gets dark and light shines on them, they glow. "This helps you to be seen better!"
Do you know any other parts on your bike that help you in the dark?
The two lights! A white one in front and a red one in the back. The light in front is called a headlight. The light at the rear is called a taillight. They should always work and are usually powered by a dynamo. A dynamo is small generator that powers the lights. Always check that both lights work before you ride! You also have reflectors on the front and back of your bike. Do you know the color of the reflectors?
The reflector in front is white, and the reflector in the back is red! With reflectors and working lights, you will be safe in the dark. But what other parts are there?
This is the bicycle chain. It should not sag, so that the bike rides well. And these are the pedals of your bike. These also have reflectors. What do you do when you want to stop your bike?
Well, you brake of course! Your bike should have two brakes: a front brake and a rear brake. These MUST work well. You can try this out by pushing your bike a bit and then braking. And where do you sit on your bike?
On the saddle!
Make sure it is set at the correct height. An adult can help you with that. And what do you steer with?
With the handlebars! What is the name of this part that is attached to the handlebar?
This is the bell. It helps you to draw attention to yourself.
Let's take a quiz! Can you see why this bike is not roadworthy?
The tire is flat! Before you ride this bike, you should pump it up, or repair the tire. And why is this bike not roadworthy?
The bike has no tail light! You should never ride without a working tail light. And what is missing from this bike?
The bell is missing! This should also never be missing from a bicycle.
Let's review, what are the parts of a roadworthy bike?
Your bike should have two wheels with well inflated tires.
There are spoke reflectors on each wheel.
At the rear, your bike has a red tail light and another reflector.
The chain of your bike should not sag. Your rear brake should always work, and your saddle should be adjusted to the correct height. Your bike also has a light in the front and a reflector. Also, your front brake should always work. There are more reflectors on the pedals. This is the handlebar. A bell should be attached to it.
But isn't there something missing so you can ride your bike safely?
The helmet, which you should ALWAYS wear when riding a bike!
