A month after suffering serious head injuries in a road traffic accident, motorcycle enthusiast Tony "de Tiger" Grant has been declared fit to leave Intensive Care.

The 22-year-old is expected to move to a general ward at King Edward VII Memorial Hospital sometime "soon".

His family is now preparing for the battle ahead a long period of recovery and overseas treatment that could cost as much as $93,000 per month.

"The doctors say he's showing amazing improvement. He started improving two weeks after the accident, opened his eyes and started moving his arms and legs. In fact, they've had to stop him from trying to get up and move around," said his mother Sonya Smith.

"He smiled at us the other night. He's reaching up and taking hold of my hand, and the other night I thought he tried to say hello to me."

Mr Grant crashed his bike into a sidewalk and tree on Southside Road, St. David's shortly after 10pm on October 19.

A member of the Bermuda Motorcycle Racing Club, he was on course to win the Formula class this year until his accident. He also hoped to qualify as a motor mechanic overseas.

The family is instead facing a challenge they didn't anticipate: how to raise the necessary funds for Mr Grant's treatment in the US.

A single parent of three, Ms Smith said that her son only has basic insurance through his job as a security guard. It means the family must cover the cost of overseas transport and care.

She is now setting up a fund for donations, and the family plans to raise money through bake sales and car washes.

"Tony needs to get rehabilitation at Spaulding [Rehabilitation] Hospital in Boston and it's going to be very expensive, over $20,000 a week. We're going to get him there somehow. My family and friends are supporting and praying with me — we do have faith that Tony will bounce back."

Ms Smith said the world has turned upside down for her and Mr Grant's sisters, 19-year-old Ashley and 11-year-old Azrah.

"I'd also like to thank my sister Stacey, her husband Aaron Burt, my mom and two brothers Sean and Scott, and all my family and friends," she said.

Despite the struggles, she said the family firmly believed that God would see them through.

"His dream is to open up a garage of his own someday. And he will," Ms Smith said.
