Icycle 2010: Ice bike races at Dufferin Grove Park. Here's a close-up view of a home-made studded bike tire. It's basically a regular bike tire with a bunch of metal screws stuck through it to give maximum traction on the ice. Commercially-made studded tires are nowhere near as aggressive as these!
This is the last on the ice bike photos for the blog. You can view the rest of them in my gallery posted here.
