Type of frame?

Hey guys,

I might sound dumb asking this but what is the type of frame where the top tube is on a downward angle towards the head tube?

Like this:

ten characters

or funnybike if it’s a roadie* (short-lived 80’s road TT fad)

*your pic don’t load for me

or a lo pro

They use a smaller front wheel - illegal under current UCI ruling, where both wheels must be the same diameter.
There are a few that have used a 700c front fork with them- most dodgy.
