The 24-year-old aspiring firefighter's cycle hit a utility pole, causing serious brain injuries and requiring that his right leg be amputated and part of his skull removed.
He's been in a coma ever since.
A GoFundMe page that had raised more than $18,000 for medical expenses as of Wednesday.
"Everyone who knows Robert can attest to the amazing, authentic person he is," said the campaign's founder and Grabias' sister, Klaudia Grabias.
"The impact he has on those around him is incredible. He always has a joke ready to light up anyone’s day. His presence lights up the room."
An adventurer and full of life, Grabias graduated college with a degree in computer science.
He had completed the civil service exam for firefighters, and was 81st on the list. Just one week before the accident, an investigator visited his house.
Although he's facing a long road to recovery, Grabias' family knows he will fight for the life he loves so much.
"The family would love anyone who knows Robert personally to share their experiences and good times with him," the GoFundMe says.
"Our goal is to someday have Robert read all these messages and videos."
