The first noticeable feature of the SM is its frame. Through design and an understanding of the functionality, these two designers have created a frame that includes no down tube. Now, it is an e-bike, so electrical components are present, only hidden; you'll see what I mean shorty.
A lack of a down tube may not necessarily be a good idea, but this depends a lot on the type of material used in the construction. Personally, I may have chosen carbon fiber to build such a body as it offers some flexibility. However, the designers chose hydroformed aluminum to express the forms they had in mind. That isn’t a bad thing, as aluminum can be just as good for certain shapes and stress points, sometimes even better than carbon.
Try to guess where the battery pack may be hidden. If you answered "in the frame," you might very well be a designer. Right in front of the seat, a bulge accommodates the battery, offering easy access thanks to a seamlessly integrated hatch in the top tube.
As for the motor, that is where things get a bit odd. The designers chose to throw out conventional motor mounting and have positioned it in the rear triangle formed by the chain and seat stays. Usually, this space is reserved for derailleurs, brake mounts, and linkage. Here, all that leftover space is filled with a rather odd motor. How that dual-chain system is supposed to function, I haven’t the slightest clue. No mention is made on the designers’ Behance page either.
To stop this e-bike wannabe from taking things too far, a pair of classic V-brakes clamp down on what looks like a pair of aluminum tires. On the tires, there's a tread pattern like those found on gravel bikes. This assumption is further reinforced by the rider in the image gallery.
Personally, if this sort of design ever becomes a reality, I would really consider giving it a spin; why not. For now, however, the only spin it’ll take is in your mind. However, a somewhat rough scale model of this design does exist; it may only be a matter of time until people are out on an SM e-bike.
