A bike called Zat

I found my bike a name while I was playing around with a Janis Joplin song.

Zat is my bike
My bike Zat is very heavy to carry
Zat makes bidding for places much harder for me
I don't like that but I do love Zat
The metal machine Zat can get me anywhere
Zat carries my shopping when my son is not in the seat behind it
Zat also doesn't omit carbon emissions and is therefore very good for our planet
Zat is a very fine thing no?
Think about Zat you people in the council.

There are perks to going mad. My bicycle has a name!
