also idk if its intended but if you have propeller already active, then you activate mini bike it just shrinks the wheels but when you die it makes the whole bike smaller with propeller
the mini-bike affects the springs, which will only update when the game is unpaused (the wheel size changes automatically though), so that causes the visual quirk. but I’m trying to replicate what you’re saying, not shrinking until dying, with no luck. it should update as soon as the game is unpaused.
