The Return of Blogpoetry

I'm experimenting with the world of poetry again after a long, too long, hiatus. I love format, meter, and structure, therefore, I love haiku and have been experimenting with something new: the Limerick! Won't you join me please in exploring and testing out something new? Please, if you have any suggestions at all, I'm game for anything! Which is which?

Tender, derelict
Autumn brown downward tumble
Fall, fall, fall, fall, fall...

On bicycle green he pedals.
First left foot, then right foot they treadle.
Not moving with greed,
Heart aflutter, high speed.
'Pon chrome-spoked wheeled steed joy won't settle.
