Here in the Emerald City all of our buses have holders on the front for people attach their bikes. I think sometimes people are going to places to ride and don't want to fight traffic to get there, or maybe the trip is just a little too long to ride the bike the whole way, so they're compromising with public traffic.

And I adore the idea of the horsey bike. I remember they used to sell short broomsticks with plastic horse heads on them for kids to "ride" [dating myself]. Simple pleasures!
