If you are a hip person and dress hip and have a hip bag and a hip bike and you can ride to work without becoming a sweaty mess, sure bike commuting can be hip.

If you are instead like me, and you are fat, wear bike shorts and an athletic shirt from Target, and have a Trek hybrid that you commute on and carry your crap in panniers and wear a dorky helmet and can't ride anywhere without becoming drenched in sweat, then no you are not hip.
