My concern with the Lafree would be the 7 pound rear rack battery which will make it top heavy. Really, you don't want that!!
As far as Frey backlog, they posted delivery time for new orders is 50-60 days, so roughly ~2 months. Not that big a deal. It's 3 weeks longer than normal. Another potential downside of the Frey CC is it's going to be heavy to lift with full suspension, ultra motor, and 840wh battery. Consider how you will be transporting and storing your bike.
Whatever you do, don't rush your purchase. I'd ask around and see if you can find a few other users in your area with ebikes. Take a few test rides to see what you like and don't like. Dont go to a dealer and make an impulse buy. It's a big investment and you have plenty of time. Weather won't be getting nice here in WA for at least 3 months anyway.
