'Chilly' Miller, 29, was found dead in a van outside a friend's home in Mammoth Lakes in California. He had been living in the van.
"He loved life so much; it made him easy to love and easy to be around," Bode told The Ski Channel.
"I’m going to miss him a lot."
Chelone had apparently suffered a seizure. He had a history of such problems ever since a 2005 motorcycle crash in his home state of New Hampshire which put him in a coma for 11 days and caused him to lose his memory for a month afterwards. On one occasion, he had a seizure while on a chairlift and fell 25 feet.
Foul play is not suspected.
He won the Rahlves Banzai Tour overall title after winning at Sugar Bowl in Californi last month and was eyeing a spot in the USA's snowboardcross team for the 2014 Winter Olympics in Sochi, Russia.
US Ski and Snowboard Association president Bill Marolt said: "Chelone Miller was an aspiring elite athlete who had made great progress as a snowboardcross rider this past season.
"We are all deeply saddened at the news of his death and extend our condolences to the entire Miller family."
