Time to pump up the tires and lube up the chain, Bike Month is here again. From May 25 to June 25, hundreds of cycling-related events will take place across the GTA. From tune-ups, to repair workshops, to Polish-themed bicycle rides around the city's west end, you're bound to find something to match your level of enthusiasm and skill level.

Bike Month traces its origins to the first Bike to Work Day in 1989. Since then, it's grown into a highlight in the Toronto bicycle calendar, with events in Mississauga, Hamilton, Burlington, Milton, and Peel, York, and Durham regions. Bike to Work Day still runs. This year it takes place on May 25.

Here are 10 highlights from this year's calendar of events.
