Animatronics expert Matt Denton has taken a nostalgic leap into the world of LEGO with his latest creation: a rideable LEGO Technic Cafe Racer, powered by an electric motorbike and assembled using 3D printed parts. Denton’s project is based on the LEGO Technic 8810 Cafe Racer set, originally released in the 1990s, and cleverly merges the playful spirit of LEGO with modern 3D printing and electric vehicle technology. This project, which Denton documented on his YouTube channel, showcases the blend of creativity, engineering, and DIY craftsmanship that brings the concept to life.
Inspiration from the LEGO Technic 8810 set
Denton’s rideable motorbike is heavily inspired by the LEGO Technic 8810 Cafe Racer, a set beloved by LEGO enthusiasts. His goal was to recreate a full-sized, functioning version of the 8810, utilizing 3D printing to manufacture many of the necessary components. Staying true to the LEGO philosophy, Denton made sure that these 3D printed parts were modular, allowing them to be attached and detached like real LEGO blocks. The use of PolyLite material combined with polycarbonate gave the parts the durability needed for an electric bike while retaining the characteristic look of the original LEGO set.
The key structure of Denton’s creation is built on the body of an electric monkey motorbike. While his initial idea was to 3D print the wheels of the bike as well, he opted instead for an e-bike kit that included essentials like a motor controller, screen, disc brakes, tires, and brake levers. This kit provided the necessary functionality, though Denton ensured that many of the kit’s components were cleverly concealed beneath his 3D printed LEGO parts, maintaining the visual integrity of his LEGO-inspired design.
The build process: From 3D printed handlebars to electric wiring
Denton’s build process, as detailed in his videos, began with assembling the handlebar using custom 3D printed parts. The front wheel was then installed, followed by the transparent, 3D printed headlight. The project took shape slowly but steadily, with Denton painstakingly joining the various 3D printed components of the motorbike’s frame using bolts for durability.
The next steps involved attaching the foot pegs, suspension, and axle—crucial elements for ensuring the bike’s stability and functionality. To maintain a clean, LEGO-inspired aesthetic, Denton hid most of the wiring for the bike inside the custom-made frame, avoiding any visible clutter that might disrupt the blocky design. Once the structural components were in place, he fitted the bike with a seat and added the battery, which is housed in a water bottle-shaped compartment, complete with its own bottle holder-style frame.
Bringing the LEGO bike to life
With the assembly complete, Denton tested the motorbike’s controller, making sure the wheel could reverse and function properly. The first trial spin took place indoors in Denton’s workshop, where the bike performed smoothly. After adjusting the power and steering, Denton took his creation outside for a test ride in a nearby court. The rideable LEGO Technic Cafe Racer handled well, and its design, reminiscent of the LEGO 8810 set, added a playful touch to the experience.
To further validate his creation, Denton invited special effects designer and YouTube personality Adam Savage to try out the motorbike. In a lighthearted moment, Savage took the bike for a spin and jokingly remarked, “I would pay five bucks to do this,” hinting at the fun and charm the custom vehicle offered.
