The new bikes?
What fabrication skill level do you have to reach before you can get the bikes? My sim is level 8 and still can’t make any,

That's one of the "secret" recipes. You need to have your sim "Enthuse about fabrication" to other sims. It has a 90 min cooldown, and I'm not sure you actually learn a new recipe every time. Also, some NPC's will craft special things for your sim, and I believe your sim will then learn that recipe (like upgrade parts etc.), even food recipes can be learned that way.
