I've been riding bikes for 20 years now, and I never get bored of them. 12 of my bike paintings have survived, and I also do oil reproductions and buildings. Its just a hobby for me, as by day I'm a mortgage advisor and by night I'm a landlord. Painting pictures relaxes me, and I get a huge amount of satisfaction when people buy the prints. Its a sense of satisfaction that money can't buy, so I recommend taking the hobby up. Everyone can do it if they put their mind to it.
