In celebration of April Fools’ Day, a British bike repair shop took its prank game to the next level by building a highly ambitious—and humorous—tandem bicycle. Cheshire-based Target Composites spent three weeks constructing a modified version of Cannondale’s top-tier SuperSix EVO, merging two frames into one extraordinary creation: the “SuperTwelve.”
The bike, designed with the notion of combining the performance of two SuperSix EVO bikes, uses spare carbon parts to achieve a full build. According to the shop’s social media post, “What’s better than a SuperSix EVO? Two SuperSix EVOs.”
The result is a lightweight tandem weighing just 10.6kg, offering an impressive “watts per kilo” ratio, designed with an innovative open diamond rear end. This design provides extra compliance for enhanced comfort while maintaining torsional rigidity and minimizing frame weight.
Target Composites explained that the idea wasn’t originally conceived for an April Fools’ prank. “We initially planned to use old SuperSix frames we had in the shop, but when the name ‘SuperTwelve’ came to mind, it quickly became a fun concept for April Fools’ Day,” said Jack, a carbon repair technician at the shop.
The build process included a complete team effort, starting with a detailed plan. The team cut and adapted frames, removed the seat stays from the original SuperSix, and bonded spare carbon parts in a jig. The final week of the project involved painting and adding finishing touches, along with the installation of a wireless SRAM Red and Force groupset for smooth shifting.
While the tandem has not been test-ridden yet, Jack mentioned that with some minor tweaks, including the addition of a cross brace, it could be “perfectly rideable.”
Estimating the cost of such a build, Jack admitted, “It’s difficult to say, but it’s taken us around three full weeks of labor, plus some additional parts to make the drivetrain functional.”
A Cannondale spokesperson humorously remarked, “Double the power, twice the rider, twofold the saddles and half the number of team bikes, the SuperTwelve is the next step in pro cycling!
This isn’t the first time Target Composites has embraced April Fools’ creativity. The shop, known for its carbon frame repair expertise, has previously built a Factor road bike without seat stays, deep-section wheels with built-in storage, and even urns for a “bike cremation service.
With the SuperTwelve, Target Composites proves that practical jokes can also be impressive feats of engineering.
