That sounds just like the toy plane Laka launches in BF4. Someone near me must have one 'cause as soon as I hear it I start to look for the red light and run for cover! There is also a bird in the garden that makes a noise like those ball beacon things also in BF4...
Apart from it braking when I got on it, if it didn't brake I doubt it would have enough power to actually move with me on it. And I doubt there are enough cows to make a suitable leather riding suit for me.
