Cycles and Sheds

I bought myself a new bike. Dreamt of doing this before.
Maybe I should follow my own advice.
Anyway, the new bike was a racing model with very narrow wheels.
I gave it a whirl, it could go very fast, even faster as I narrowed the wheels down a bit.
I found I could do this by pure thought. Handy.
I was going faster and faster.
I then became aware that if the wheels were too narrow they would just cut into the road.
So, I achieved a happy but zippy medium.

I also found that I had materialised a new bike shed in the middle of the garden. Blocked the view a bit but perhaps materialisers can't be choosers.
