local Speed = OreModule[tostring(SelectionBox.Adornee)]["Speed"]
local MineInfo = TweenInfo.new(Speed)
local NewTween = TweenService:Create(Bar, MineInfo, {Size = UDim2.new(0.948, 0 , 0.81, 0)})
NewTween:Play()
            
NewTween.Completed:Connect(function()
     BringBackDown()
     NewTween:Play()
end)

I wanted to do something like this but it crashes the game. Is there a way to make a repeating tween?

TweenInfo has a RepeatCount and Reverse parameter and what they do is self explanatory. You can read more here: TweenInfo | Documentation - Roblox Creator Hub
