Is a bike and dumbbell set pretty good for a healthy work out plan?

VII: Is a bike and dumbbell set pretty good for a healthy work out plan?
I bike 30-60 miles a week at a pretty good pace already but i read that it is a good idea to throw in strength as well as flexibility to your cardiovascular work outs.
Now I am a very skinny guy with all the biking I do already, but is the biking, dumbbells and standard stretching sound pretty good? Should I throw something else?
I’m on a budget so i figured those things should suffice.

Cardio workouts (like bike) will burn lean muscle which i assume you want to hold on to. If you do an interval type workout, alternating between weights and cardio you will burn off body fat and retain muscle. Dumbells and strecthing with bike sounds like a great option to me.
