A schoolboy born with no left hand can finally safely ride his bike after £13k was raised for an Iron Man-style bionic arm.Jacob Hyatt, seven, was born without his left hand and, while it didn't hold him back, he had a go with a high-tech prosthetic last year - and fell in love.But the custom made limb cost £13,000 and his mum Bernice Hyatt, 33, shared a fundraising page online in the hope kind donors could make her son’s dream come true.Jacob, from Eaton Bray, Beds., was finally able to pick up his superhero-themed arm from Open Bionics last month after the target was met.Florist Bernice said: "He keeps asking me to put on music so he can clap along - and he wants to high five or fist-bump everyone he meets."I have always taught Jacob it's good to be different - you don't have to fit in."But despite that, there are things he has always struggled with, so the second he tried on the bionic arm, he was desperate to get one."Leading up to the day he got the arm, every day he would ask 'Mummy, why is it taking so long?'
