Tern is moving out its usual markets, it will be difficult to compete against well established competitors like Riese & Müller that use same Bosch components.
The lack of suspension (no rear suspension but even no suspension fork) is a real weak point for such an off road bike. Wide tires cannot replace a real suspension.
Front suspension would be easy, just different fork.
Rear suspension on a long-tail, it can be done, but it's more difficult with the longer moment arm, both vertical loads, and also lateral loads transmitted through only that pivot point, so greater moment with the longer swing arm.
From the truncated picture and only a glimpse in the video, I'm not liking the frame design aft of the rear axle; under vertical load it's gonna have a stress concentration where that short horizontal meets the seatstays just forward of the rear axle.
Market: An off-road e-bike could be very useful in the third world, with solar or wind generator charging. Tern has done well with the e-bikes, especially the GSD to the affluent in the USA. This model has larger wheels and tires, perhaps needed with heavy loads uphill on dirt. Otherwise I don't see the advantage over the GSD. Where Tern could have an advantage over R&M is in pricing, if they desired to undercut them, but the GSDs haven't.
