It has become a familiar sight for Winnipeg bike owner Ron Janzen, an open space in his garage where a bike used to be.

Over the years he has had eight bikes stolen from him.

"It’s wrong, it's theft of personal property," Janzen said.

Janzen stores his bikes locked inside a secure garage, but he said even that is not enough to deter thieves.

"I think part of it is the attitude that it is sort of not a big deal to steal a bikes and somehow that culture needs to change," he said.

"I wish there was something we could do about it."

Police said bike theft in Winnipeg has doubled in just two years and while some of it has to do with warmer weather and more riders, other times it is because of poor locks.

Dean Sampson owns a Pembina Highway bike shop and believes a lock is only as good as where and what you lock it to.

"If people were preemptive on things they wouldn't have their bikes stolen as much," Sampson said.

He said many times people make it too easy by locking their bikes in the same place each day.

Sampson recommends his customers to lock in high traffic areas and to use two separate locks.
