I’ll be honest, I haven’t heard of the brand. But that’s true of probably a majority of the ebike companies out there.
There are so many brands, it’s hard to keep up. I think we’re in the Wild West of development right now, and over time the crappy bikes will fade away, and the strong companies will survive.
Your post prompted me to look up the website, however, and the bikes look pretty nice. Can’t beat the 5-year warranty (although a warranty is really only as good as having a LBS willing to service it, IMO).
I haven’t seen an ebike with the battery mounted in the rear rack either. That’s pretty cool (I wonder if it limits your rear cargo weight capacity, however).
The tandem bike under $4K caught my eye. Might be fun getting my wife out on some of my rides (sans enjoyment of my peace and quiet

).
