Breaking Design Rules Through a 3D Printed Bike With All-Wheel Drive

Can you imagine riding a bike that is designed completely differently than what we know today? Well, German designer Stephan Heinrich has brought this idea to life using additive manufacturing. The Infinity is a concept that could break the rules of design as we know them today. It’s an all-wheel drive bicycle that at first glance seems like an idea from the future, but which could be closer than we think. Though currently modern engineering marvel is still in the concept stage, 3D printing has made it possible to bring the idea of this bike to life and demonstrate its long-term viability.

This is not the first time that 3D printing and bicycles have come together in a project, especially in the development of parts. In general, this technology allows the production of bicycle frames optimized to reduce the final weight of the bikes. In this case, however, 3D printing played a completely different role than we’re used to. It was used to build the small prototype of this revolutionary all-wheel drive bicycle concept. Though, it still remains to be seen whether the idea will come to fruition and whether 3D printing will be used to manufacture some of the parts.

The 3D Printed Bike Prototype

The all-wheel drive bicycle would have a monotypic chain system that forms a temporary rim on the wheel sections and a toothed belt drive in the inner groove. The method by which the bicycle propels itself is at the center wheel, as the crank generates the power needed to move the wheels. Thus, the bicycle is set in motion with the help of the short chain and an 8-speed gearshift, which is not comparable to that of conventional bicycles. Heinrich used selective laser sintering technology from the manufacturer Sintratec to develop this small-scale prototype.

The bike’s name, “The Infinity,” comes from the structure of the four-wheel drive itself, which is shaped like the infinity symbol. As for damping, Heinrich says the 3D-printed bike will have independent suspensions front and rear. This will allow the bike to adapt to and handle all kinds of bumps. The designer is still working on developing this concept, but he is sure it could revolutionize the market and break current design norms. “If the necessary funding is raised and strategic manufacturing partners support the project, the bike could soon go from a concept to a prototype and then to a commercially viable product for the masses,” he concluded. Whatever the future holds for this idea, we’ll keep you posted on any new developments.

  • I genuinely do not understand how someone clever enough to design this is also stupid enough to design this.

    • It's clearly designed for Möbius Track Racing. OFF-TRACK they would just steer like the bikes from TRON.
      Honestly, I think the branding concepts are limitless.
      The problem is you guys are only thinking in 3-dimensions.

      "OMG". Just came up with the company byline!!!!! --Don't berate. Be Gr8!!!

  • Very interesting design, but how would you steer it with a fixed chain system as shown?

  • How will it work when it goes round a corner? Assuming the tyre can bend, I'll accept, but how will it adjust the differential speeds of the two contact points?

  • Sure, it looks awesome and will probably be great. Until you want to turn... this guy is supposed to be smart?

  • Maybe only aimed at super expensive track bikes...so he only has to sell a few thousand. Steers more like a motorcycle where you push and lean. Not actually designed for he masses to enjoy....

  • Somebody needs sleep ......"The bike’s name, “The Infinity,” comes from the structure of the four-wheel drive itself" uh I'm sorry 4?

  • It's a money grab. This thing looks like a nightmare. Steering might kink the tire or disengage the gears. A flat would be super-expensive and require total disassembly. A rock in the gears would strip the bike and possibly cause major injury when the wheel locks in place. While it's appealing in a science-fiction sense, in the real world, this thing is a major class action lawsuit waiting to happen.
