Cox had already been selected in the ParalympicsGB athletics line-up as a sprinter and the 25-year-old from Chapeltown has now had her place in the cycling team confirmed.
Louis Rolfe was also named as the British Paralympic Association (BPA) today revealed its two final riders for the cycling team
“I’m delighted to be selected and be on the plane to Rio,” said Cox, who ParalympicsGB believe will be the first British athlete to compete in two sports at a Games since 1992.
“I’ve already won a world title in cycling earlier this year and I’ll be giving everything I’ve got to add a Paralympic gold medal to my collection.”
Rolfe completes the team sprint line-up alongside Jody Cundy and Jon-Allan Butterworth, and will also compete in the individual pursuit on the track and time-trial on the road.
“I can’t believe that I’m going to be going to my first Paralympic Games in Rio,” said Rolfe.
“It’s been a dream of mine ever since I started cycling to be selected for a Paralympics. I’m really looking forward to competing against the best in the world and showing what I’m capable of.”
Cox and Rolfe are the final two additions to the cycling team, the majority of which was announced in mid-June. Britain’s most-decorated female Paralympian, Dame Sarah Storey, will be gunning to add to her tally of 11 gold medals.
