Even if it's not an especially realistic design, I do appreciate that it at least contains some interesting architecture and design concepts that go beyond solely aesthetics, though obviously the impeccable realization of the look is probably 90% of the concept.
I like the beam-frame structure, and the adoption of cables as tensile elements, both of which I think have not been explored enough in contemporary bike design. The hubless rear wheel, however, is always a groaner, though…the ultimate triumph of aesthetics over practicality.
i am not that sure, that a hubless wheel such a stupidity and just a simple eye-catcher.
from mechanical point of view, it's a lot better to insert forces at the rim not at the hub (leaver). it also saves a lot of weight by shortening the drive-train. just fair to mention, that of course the rim has to be more rigid and that maybe equals the gains from the drive-train cutting.
You've hit the nail on the head with the latter point. A hubless rim needs to be dramatically stiffer because any out-of-tolerance on a hubless wheel affects drivetrain efficiency as well as braking and ride. And because all that extra mass is located at the rim, the rotational inertia is hugely greater.
The spoke-tensioned wheel is a thing of engineering beauty.
The handlebar puts you in about the same position as you would on a Tron lightcycle and may require you to slouch due to its bike structure.Stated as a racing bike, the Peugeot B1K Concept Bicycle uses a chainless drivetrain, and carbon fiber materials. As of now, not much is known on production, and more than likely we can say this is eye candy.Army ration Packs
People, put down your pencils and simply enjoy the beauty of the design.
