A blue Mercedes SLS AMG sports car body with bicycle wheels. The gull wing is open to reveal the spartan interior and the hood is open to reveal an empty engine compartment since this is actually a bike.

SLS AMG Velomobile

Many gearheads dream of owning a supercar, but their exorbitant prices make them unattainable for all but the most affluent. [Andrzej Burek] decided to make his dreams come true by building his own supercar with a human-powered twist. [YouTube]

At first glance, [Burek]’s SLS AMG looks like the real thing. Pop the hood, and you’ll find this “car” is missing it’s V8 which has been replaced by a beefy speaker pumping out engine sounds from any car you choose. Both driver and passenger can provide propulsion for the sociable tandem, and the power is routed through a differential to the rear wheels. [Burek] decided to install the differential to make installing power assist motors simpler in future revisions of this quadracycle.

[Burek] said it’s taken him four years from buying the first component to the bike’s status in the video after the break. Other than the front and rear bumpers, he built the body himself out of fiberglass to learn how to work with the material. He welded the frame himself as well, and, in a testament to good measurements, the two parts fit together when united despite being built in separate locations. You can checkout more pictures on his Instagram.

Chainless Bicycle Will Turn A Few Heads

Someone let [Tane] play around with welding equipment and bicycle parts and look what happened! He built a diminutive velocipede. Now that’s just a term for a human-powered land vehicle, but the term fits a bit better as this is missing most of the stuff you’d expect to see on a bicycle.

He started with a mountain bike and a kick scooter, then went to work on both with a hack saw. A bit of welding and angle grinding left him with what you see above. It’s still steerable, but missing are the cranks, chain, and brakes. That’s okay though, the bike is low enough for your legs to reach the ground – you start it up and come to a stop Fred-Flintstone-Style.

[Tane] originally meant to add electric propulsion but didn’t quite get around to it. There’s always the option to add a hub motor to the rear wheel if he has the time and motivation.
