The LEGO Technic 8810 Café Racer, originally released in the early ’90s, was a favorite for both kids and adults. Known as the Technic Alpha Racer, its value has grown by an average of 3% annually. Inspired by this collectible, animatronics creator Matt Denton developed a rideable version using 3D-printed parts, preserving the attachable nature of LEGO bricks. Each part is made from PolyLite and polycarbonate to mimic the snappable plastic blocks.
Matt Denton, known for his engineering creations like the Star Wars BB-8, has now built a functional electric monkey bike inspired by the LEGO 8810 Café Racer. The 33-year-old designer crafted a rideable two-wheeler that supports an adult’s weight but, like typical monkey bikes, can be tricky to steer in tight spaces. To build it, he used an e-bike kit with a motor controller, screen, disc brakes, tires, and brake levers. Combining the kit with custom 3D-printed LEGO-like parts was a challenge due to vibrations and engine noise.
To keep the LEGO-themed look, Matt only used essential parts from the e-bike kit. He first 3D-printed the handlebar and positioned the front wheel, then added the headlights. After finalizing the frame, he worked on the foot pegs, suspension, axle, and wiring. The last components added were the forks, seat, battery, water bottle, and a bottle holder frame.
He then tests the rideability and reverse function. After adjusting the power, steering, and brakes, the LEGO Technic café racer is street-ready.
