Now listen and answer the questions.

Bicycles, or bikes, are a great invention for getting around.
00:00:06
Human energy makes the wheels go round and moves you along the road.
00:00:13
This is faster than walking, and it's economical and eco-friendly too.
00:00:19
But do you ever get tired?
00:00:26
If the answer is yes, you need a solar-powered bike.
00:00:28
It has lots of small solar panels that use energy from the sun to power a small motor on the back wheel.
00:00:34
So when you are tired or going up a steep hill, you can just press a button and take your feet off the pedals and the bike keeps going.
00:00:45
The good news, it works on a cloudy day
00:00:56
The bad news, it's not in the shops yet
