There definitely are, they make them in a variety of sizes, so they should fit your bike fine.
But, be aware, it’s different when using them. If you have a mountain-bike style tire, snow might be ok, but ice is dangerous. It’s basically the opposite with a studded tire. If the snow is thick enough that you ride on top of it, you won’t have much traction. You want the studs to bite into the ice instead.
are there any studdded bike tires (I would love them for my ebike)?

looks like Schwalbe makes some MTB ones. not sure what size you’re looking for.
