single speed 

A bike with a single gear, similar to the days gone by when bikes didn't need a realm of cogs to propell itself forward. This is of course a free hub, not a fixie.

Dom was a pervert, he converted his geared mtb to a single speed.

Singlespeeder 

Derisory term applied to someone as a consequence of their disappointing or unfulfilling sexual performance.

"We was at it for ages last night an' he still never got me up the mountain. After half a shandy he's a proper singlespeeder, and he just has to get off and wank/walk".
