I've had a bike since 1972, it was my primary ride to High School.Riding motorcycles has always been a passion of mine and I take several long (1000-1500 mile) solo trips every year.
If you want to share your DH's passion then there is no better place to start than The Class. Don't worry about being a newbie, everyone in the class is new and clueless and the curriculum is designed with that fact in mind. The fact that you regularly ride a bicycle will be a huge asset as well. Good luck and enjoy yourself, if you have any specific questions feel free to give me a shout.
