An 85-year-old Burnaby senior hopes a heartless thief returns a bicycle that has rolled 4,700 kilometres across Canada, and carries countless memories of a magnificent adventure.

Cor Dykstra's treasured Apollo 10 speed bike was stolen from the garage of his home on June 8, Burnaby RCMP said.

Dykstra rode the bike eastward to visit relatives in Ontario in the early 1980s, making it all the way to Regina, Sask., on his first attempt in 1981, before falling ill.

In a second attempt, at the age of 57, Dykstra rode from Burnaby all the way to Chesterfield, Ontario in just 30 days - 200 kilometres per day.

"It was just exercise, and a trip to see my daughter and that was really it," he said.

Police say the painstakingly-maintained bike was mounted on the garage wall of Dykstra's home, helping him remember that trip in vivid detail.

A New Westminster Police officer spotted a similar-looking bike ridden by a man believed linked to similar break-ins, but the suspect escaped.

Officers are now appealing for anyone with information to call the Burnaby RCMP at 604 294 7922 or Crime Stoppers at 1 800 222 TIPS (8477).
