The Sleep Cyclists 

A wonderful underground Indie band made up of a group of wonderful boys from Wisconsin.
The musicians are:
Nathaniel Corey - Viola

Christopher Peterson - Percussion

Adam Jordahl - Bass

Timothy Anderson - Guitar/Vocals

Jack Kyoung Heon Kim - Trumpet/Piano/Percussion

Jed Munson - Ukulele/Vocals

They make beautiful alternative music and are pleasantly aloof (or at least Tim is..)

"have you heard of the Sleep Cyclists?"
"no."
"oh, well they're this wonderful indie/ alternative band from Middleton, Wisconsin."
"peachy"

Arsehole of Cyclists

keen cyclist 

Someone who doesn't ride a bike at all, but has one in the shed / garage from years ago (usually with flat tyres, rusty chain and seized up components).

Always used by someone objecting to / complaining about any cycling infrastructure, to try to give credibility to a selfish argument or point of view.

I'm a 'keen cyclist' but I don't want these cycle lanes in front of my house.
