My wild-@ss guess is, something like the origami bull, semi-fat tires and discs, and no, I'm not a shill for that guy. I just said in another thread, Tern used to run similar products as Dahon, but in recent years they have swung for the fences with bikes like the GSD ($6k to $10K, depending on gearing, I see big profits in those numbers, however, "The business sin of premium pricing", that leaves tons of room for someone to undercut them on price). Would I buy a lesser known brand for 30 or 50% less, no. But I saw on the road an electric that compared well with a GSD, and it was $1500-2000 USD (I can't recall exactly), heck yeah I would go for that, if good reviews, and I wanted an electric. But I'm set for a good number of years with my humble dahon speed with gearing mods and good racks.

By the way, I hate teaser ads, just show the darn product already. I hate marketing.
