Fixed gears, no brakes, and eye-watering speeds – what more could an adrenaline junkie want? If you’ve never watched the sport of track cycling, I’d highly recommend visiting a velodrome (or at least watching it on TV during the Olympics this summer). It’s not just biking in circles. These insane athletes zip around the bowl-shaped track, vying for position like gravity-defying daredevils. Being aerodynamic is key, as demonstrated by this LEGO kinetic sculpture, built by George Panteleon.

Though the mechanism is simple, it’s so satisfying to see the rider’s legs “pedal” the bike. My favorite elements of this build (other than the fact that it actually moves) are the paint-roller handlebars and the shoulder armor turned helmet!

We’ve also featured several of George’s vehicles, a giant watch, and some outstanding character sculptures!
