If you ever put a 3' pool noodle with a flag on the side your bike to ensure drivers obey the 3' law, you might be a Fred.
If you have more than a bike computer and headlight clamped to your handlebars, you might be a Fred.
If you gopro the full 30 minute commute to work every day and post each one to youtube, you might be a Fred.
If you wear an orange safety vest any time riding a bike, you might be a Fred.
If you complain about presta velve stems, you might be a Fred.

Not that any of these are bad, or wrong...just saying they're a bit on the Fredly side.
