Bus v Bike

The boyfriend started work today and refuses to pay the £4 fare (like I do every day) to get to town and back, so instead bought himself a bike, waterproofs, bike locks, lights, bike cover...I could go on. Call me lazy but I'd rather hop on the bus, than cycle 4 miles down a dodgy cyle track in the pouring rain. What do you think, is the bike really better than the bus?
