This is the best LEGO Onewheel made today, a unique creation by the renowned LEGO Technic enthusiast, Jan “Klimax” from the Czech Republic. This masterpiece, a C-model of the 42141 McLaren Formula 1 set, is a testament to the limitless possibilities of LEGO. Built using just 25% of the available pieces from the set, the LEGO Onewheel stands as a symbol of innovation and efficient design. The model keeps the lines and design features of the real Onewheel.
Klimax, a passionate LEGO Technic hobbyist, has been creating functional models, MOCs (My Own Creations, from single sets, without adding any additional pieces. Despite the challenges of balancing a full-time job and family responsibilities, Klimax has built numerous models since 2018, each one showcasing his innovative thinking and love for building. In 2023 he decided to build the Onewheel LEGO model even if he doesn’t own any board himself. *We should push Future Motion Inc. to get him one!
The LEGO Onewheel, along with other creations by Klimax, are available on the Rebrickable site, where he offers the instructions for free.
Onewheel (42141 McLaren Formula 1 C-model LEGO® Technic™)
The set is built by 356 parts from the LEGO® Technic™ 42141 McLaren Formula 1 effectively using 25% of the available prices. The instructions are free and are uploaded on the Rebrickable site.
Technical Breakdown of the LEGO Onewheel
The LEGO Onewheel uses 356 parts from the McLaren 42141 set. The wheel assembly is built around a reinforced Technic hub that keeps the structure rigid while still allowing rotation. The footpads are angled to mimic the stance of a real Onewheel, and the frame uses a compact beam layout that keeps the proportions close to the GT and Pint models. The model is surprisingly stable considering the limited part count.
How It Compares to a Real Onewheel
The proportions follow the real board closely. The center wheel is slightly narrower than a real Vega tire, but the overall silhouette is accurate. The footpads have the correct offset and height difference. The stance angle is close enough that riders will recognize it immediately. The model does not balance on its own, as it doesn’t have a motor, but it rolls smoothly when pushed.
Instruction Quality
The Rebrickable instructions are clear and easy to follow. The build takes about one hour for an experienced Technic builder. The wheel assembly is the most complex part, but the steps are well documented. No additional parts are needed, which makes this a true C‑model.
About Klimax
Jan, or as he is called in the LEGO scene Klimax, is a passionate Lego Technic enthusiast who returned to his hobby after a 20+ year hiatus, sparked by the birth of his son and the rediscovery of his childhood Lego sets. He started with smaller models, then moved on to the 42009 Mobile Crane and 42043 Mercedes Benz sets. The versatility of the 42043 set inspired him to build his own MOCs (My Own Creations).
His goal is to build as many functional models as possible from a single set, without adding any additional pieces. He prefers manual functions to ensure child safety and playability. He also aims to add new functions to recent models and those that are no longer easily available. He creates digital models or instructions for his creations, so his son can build them independently when he’s older.
Despite juggling a full-time job and family responsibilities, Klimax has built numerous models since 2018. He enjoys the building process but finds creating instructions time-consuming. As a result, many of his models are waiting for instructions to be created. Once completed, he offers them on Rebrickable at a reasonable price, considering the time spent on creation.
Klimax is open to collaborations on creating model instructions. His journey showcases innovative thinking, a love for building, and a commitment to sharing his passion with others.

For Onewheel riders, this model is more than a LEGO build. It is a compact representation of the board we ride every day. It is also a good teaching tool for explaining stance, tilt, and center‑wheel dynamics. Klimax captured the essence of the Onewheel using only a fraction of the McLaren set, which shows how flexible Technic can be.
