Hello! We have been navigating this. Ride1Up says that the rear rack for their Roadster should fit and thus the accessories that come with their easy release rack system should work too. However, when we installed on my Vorsa Lite, because of the geometry of the bike, the rack is slightly angled up. And there's no way the basket (or pet carrier or other accessories) would fit under the seat. I am tall (5'9" female) so my seat isn't exactly sitting lower. They sent me some photos of it installed on a vorsa lite in their shop, but no seat. So not sure if it's going to work.

All that being said, I have a Topeak system with the universal rack and quick release basket and it fits perfectly!
