I've actally heard the opposite- that 30 minutes all at once is better than breaking it up. I think it had to do with the fact that it gets your HR up and it stays up longer (i.e. you don't have 2 extra warm-up/cool-down periods thrown in that time frame). And of course, higher HR means you're working harder and burning more calories.
With that said, do what you can do! Like luckymommy said, I think any exercise is going to benefit you! I think the logic is probably different if you're maxing out after X minutes and you can't do more. Then by all means wait a few hrs and do it again! Breaking it up seems like a great way to increase the endurance you'll need for longer rides. Besides, two-a-days are pretty bad-a$$!
Another idea is to do what you can on the bike then switch exercises. Like, could you hop off the bike after your 12 minutes and do pushups or ab work or use resistance bands or go on a walk or do something so that you can continue with your workout.
Just some ideas
