Neighbours heard the cries from a North Surrey ravine after sunset on Tuesday night.
The man had been traveling by the side of the road in the 12400-block Park Drive when his electric scooter fell down a ravine.
He slid down 7.6 meters (25 feet), and his scooter tumbled down 18 meters (60 feet).
Neighbours heard the man's calls for help at about 9 p.m., and called 9-1-1.
Surrey Fire Asst. Chief Chris Keon said it took about two hours after the initial call to extricate the man from the ravine.
"You have to understand we have to get specialty apparatus," Keon said Wednesday. "And then, when we extricate, it's always done very methodically."
In order not to injure themselves or the man below, firefighters had to rappel down the ravine to reach the man.
The man was loaded into a special basket stretcher to bring him out.
He escaped with only scrapes to his leg.
"It sounded like he slid down, it wasn't a cliff," Keon said, noting it could had been a lot worse for the man.
