Harry wasn't exactly sure what he was getting himself into. He had always been warned that tampering with muggle devices, making them magical in anyway, was not to be done. But... this wasn't a place he had ever heard of before in his life, and Harry wasn't sure that magical rules and laws applied here.
Either way, Harry had promised that he would attempt to help the man using magic, and Harry wasn't one to go back on his word. So he found himself heading toward the stables, to meet a man who had been rather vague about what he wanted to be not accessible to certain people. Children in particular. Harry knew that the man didn't want the child to be harmed in any way, and that he didn't want the child to be compelled not to access it against his own free will. Harry had some ideas of what he could do to this device.
He found the stable in question rather easily, it was one of the few stables that happened to be occupied. His gaze traveled over the form of the swoop bike for a moment, before he focused on the young man also occupying the stable.
"Hi... I assume this is what you want to become inaccessible to a particular child?"
