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.

keen cyclist 

Someone that owns or once owned a bicycle but rarely (if ever) used it. They will often refer to their keenness for cycling when stepping in on a debate between motorist and cyclist to offer support to the motorist.

The keen cyclists main objective is to provide backup for motorists and tell actual cyclists they are wrong.

"As a keen cyclist myself I disagree. It’s important cyclists know how to share road with drivers."
