THOK Project 4 3D printed e-bike prototype unveiled
A 3D-printed prototype of the THOK Project 4, or P4, was shown at Eurobike 2023. The company claims it is the first in the world to trial a 3D-printed bike. The brand used selective laser melting (SLM) 3D printing technology to make the e-MTB’s aluminum alloy frame. This method enables THOK E-Bikes to iterate quickly and simulate the weight of the final carbon fibre model.
The company teamed up with 3D printing specialist Materialise to develop the product, printing six pieces which were then welded together. The successor to the THOK P4 will be the first light e-MTB from the brand; it appears that the company plans to use something other than 3D printing for mass production. The new model will feature a lightweight Bosch Performance Line SX motor and modular 400 Wh, 545 Wh and 725 Wh batteries with an optional 250 Wh range extender. THOK says it is still testing integrated and semi-integrated versions of the e-bike and various component combinations.
The full-suspension P4 electric bicycle has been tested across various terrains, with a video demonstration available on YouTube (see below). The THOK Project 4 is a temporary name; it is unclear what the e-bike will be called when it launches in 2024. Further information, including the pricing and market rollout, has yet to be announced.
