Because bad ideas come in all danger levels, this is a video of professional freeride mountain biker Sam Pilgrim replacing his bike’s traditional wheels with giant circular saw blades to see how the bike rides. SPOILER: Surprisingly well. Granted, Sam is a professional cyclist and can probably handle a bike with saw blades for wheels better than your average rider. Me? I am a below average rider. Whenever somebody says something is just like riding a bike I assume I’m going to end up bloody in a ditch again.
