Treadmills, often called treadmills, are good for exercise, but boring.
I came up with an idea to make it even more fun.
A man rides a bicycle through the streets.
But instead of turning the pedals, it moves as if you were walking on a treadmill.
This is a unique bike from the Netherlands.
It is said that it is combined with a bicycle so that you can enjoy the treadmill outside of the room and in the open air.
It can be matched with walking speed through a gear, and it can be used like an electric bike by attaching a battery.
A treadmill brought in to take care of one's health is often used as a large hanger that takes up only space in the living room.
