Bicycle company THOK stunned the world with the introduction of Project 4, 3D printed electric bike prototype. Project 4, a 3D printed electric bike prototype, was unveiled to the public at Eurobike 2023. The company teamed up with 3D printing specialist Materialise to develop the product.by printing six pieces that were later welded together.

The new THOK project is considered a milestone in the industry. The world’s first fully 3D printed e-bike. THOK used selective laser melting (SLM) technology to fabricate the e-MTB frame from aluminum alloy, allowing it to quickly iterate and simulate the weight of the final carbon fiber model.

The new model, which will be THOK’s first lightweight e-MTB, will feature a Bosch Performance Line SX engine and 400Wh, 545Wh and 725Wh modular batteries with an optional 250Wh range extender. THOK is currently testing integrated and semi-integrated versions of the electric bike, as well as various combinations of components.

While officially the P4 is still in development, THOK plans to equip the bike with the recently released 2kg Bosch Performance Line SX engine, which delivers 55Nm of torque in mid-travel with a more natural pedaling feel.

Technical details will still be provided by the company

Technical details have yet to be determined, but this prototype features 29-inch wheels, 150-160mm of travel between the RockShox Lyrik Ultimate fork and Deluxe Select+ shock, and a flip-chip in the top toe bracket for height adjustment. curb or rear wheel travel.

The P4 Full Suspension ebike has been tested on various terrains and a video demonstration is available on YouTube (see above). The THOK Project 4 name is tentative and the electric bike’s final name will be announced when it launches in 2024. Other information, including price and market launch date, has yet to be released.

The 3D printing method made it possible to create unique products with less material. The company was also able to print each individual frame and suspension element as a single unit and then process their interfaces. These include the inclusion of features such as flip chips, internal routing, more integrated electronics, and the ability to use a modular powertrain and battery guards.
