I dunno. Yellow Bike (It's a proper noun, not "The Yellow Bike", or "Bruce's Yellow Bike", but "Yellow Bike") is more like a puppy. Fast and frisky, all it wants to do is run and play.

The Portland, I can't quite pin down so easily, but its personality is completely different.

I love them both and could never choose between them. I pat them and thank them for a nice ride. And I apologize when the motor is having an off day.
