That's my concern too. And you can't simply change the MY18-rear fender light when it's broken, you need the whole fender with the light on it. Specialized has changed the rear light with the 2020 model so it might become complicated to order the MY18-spare part too.As far rolling the Vado 'on its back' from the vertical, I'd be concerned with damaging the tail light. It's going to take a lot of weight before the rear rack takes any load.
