I’m thinking about participating in a bike event (the Evolution Revolution Ride in Salisbury, Md., on April 13), so I sent them an email asking if unicycling would be OK. I got back the following response:
If you can ride a unicycle for almost 7 miles, that would amaze everyone!
That is acceptable for our event!

In Harry Potter, muggles were anyone outside of the magical world, anyone outside of the wizard’s group. In the real world the same word is used to describe someone who is not in your group. Here, muggles are non-unicyclists. It has nothing to do with “magical” and “non-magical” people or activities, it is simply whether the person described is in the same group as you. This is not unique to unicyclists, this is commonly used in the smaller, more unique sports/activities.
I figured it was because some of us ride a Nimbus… the same name as a model of flying broom in HP, at least that’s the connection everyone I know makes when they see Nimbus, and from there muggle for non-riders.
