What months do you use studded tries?
Air conducts solar energy because it allows it to pass through. For a solar cooker you want to deflect or concentrate the solar energy, and maybe focus it onto something that absorbs the energy to create heat. To deflect, you need a reflective surface, something with low emissivity and high reflectivity. To absorb you need a dark or rough surface, high emissivity, low reflectivity
I'm really happy to read all the answers here because I am 56 and wanting to get a bike. I had one 25 years ago and gave it up when I was having babies. I did have a moped and rode them around in the back to put them to sleep. Now I feel the need to go again. I am so glad to know I am not alone and too old. I was just at a cycle showroom a week ago picking out the one(s) I want. Hubby will need one too, though and he wants a bigger one. So what about the trikes, I've even thought about that.
