Sorry, wasn't really sure where to post this.

I'm looking for a business 'bag' of sorts, to go to work with but is made to fit nicely on a bicycle.

Anyone know of something like this?

I need it to be spacious enough to carry some clothes, a laptop and perhaps even a squash/tennis racket (although that's not that important) and it has to look elegant enough to carry into work without looking like a bicyle bag.

Thanks for any help!
