Hey Dennis, that's a pretty neat bike. I tried to track down specs specific to the frame/post diameter but couldn't find anything solid. Just looking at other specs and pictures though, it doesn't seem significantly larger than typical e-bikes, so I think the Swagman Adapter Bar (Large) # S57FR will work really well.
You can verify it'll fit though by taking a quick measurement of both the handlebar stem and seat post diameter on the Day 6. This adapter bar will fit perfectly as long as it doesn't exceed 2 inches. This particular model also has a longer extension (up to 35 inches) to accommodate the larger wheelbase on that bike.
The 35 pound weight capacity on the unit isn't a concern as long as you aren't using it on a hanging-style rack (no hanging-style racks could handle that bike, anyway).
Let me know if it doesn't look like this will work and I'll keep digging.

Hey Dennis, did you have a chance to measure the handlebar stem and seat post diameter on your Day 6 Ebike to see if the Swagman Adapter Bar fits? I'm asking because your experience could help others with similar bikes.
