Find my clue.

Do you fly?

Do you have two wheels?

Not 4 wheels, unsure about 2 wheels, somehow don't think it's a train. Electric powered so not a skateboard or unicycle. If 2 wheels are a possibility, how about a mobility scooter?

Have vehicles of your exact type been around longer than 20 years?

So 1890, puts it around the time of the electric car and the subway train, but it can't be one of those because the wheels are visible.

Are you a conveyor belt?
