You don't have to get dedicated bike rain pants. You pretty much just want waterproof pants, something breathable. Fullzip helps if you want to wear your regular pants underneath.

you can maybe look at the marmot precip rain jackets & pants - I know the jackets come in a lot of fun colors, the pants might not. mountain hardwear has their cohesion line, which I know the rain jackets have a lot of nice colors.


Something else to consider - depending on what sort of rain you're riding in, you could just get a pair of softshell pants - they're not fully waterproof, but are waterresistant and most water will just roll off them. I'm not recommending them for a full on downpour, but if it's just drizzling or a soft rain, they're fine.
