Mix the sweet barbecue rub and beef seasoning rub together on one plate. Place the activated charcoal rub separately on another plate.

Dip the top and bottom of each beef cube into the charcoal rub, then roll the sides in the combined sweet and beef rub mixture. Arrange the seasoned cubes on a flat cooling rack.

Position the cooling rack with steak bites on the smoker grates. Close the lid and smoke for about 60 minutes, or until the internal temperature reaches 49°C.
