Motorized bicycle

Have you seen bicycles that go really fast without pedaling? They are called "motorized bicycles". These bicycles have a special motor attached to them which helps to move the bike forward without any effort from the person riding it.

So, let's imagine you have a regular bicycle which you ride just by pedaling with your feet. Now, imagine that you have attached a special box to the bicycle which has a small engine inside it. This engine can turn on and off by pressing a button or pulling a switch.

When you press the button, the engine comes to life and starts to rotate a small wheel which is attached to the rear wheel of the bicycle. This wheel helps to move the bicycle forward without you having to pedal. The wheel also makes a loud noise which sounds like "vroom vroom" just like the sound of a car engine.

But wait, how does this motor work without being plugged into a wall? Well, the motor has a special fuel tank which is filled with a liquid called "gasoline". This gasoline is like food for the engine, which it needs to burn in order to create energy for the motor to move the bicycle.

So, in short, a motorized bicycle is a regular bicycle that has a special motor attached to it which uses gasoline as fuel, and helps you to move without pedaling. It's like having your own little car that you can ride on the road, but without a steering wheel, gears, and with all the benefits of being eco-friendly and a great workout!
