Ralf Holleis' 3D Printed Track Bike (w/ video)

3d printed bicycle

From one-off concept car bodies to wax weinermobiles, 3d printed things are not only already here, they are so definitely the future of small-scale manufacturing. It should come as no surprise, then, that someone’s gone and 3d printed-printed themselves an exotic, ultralight track bike.

His name is Ralf Holleis, and the process that went into his bike is illustrated to dramatic musical accompaniment in the video, below …

… which, you’ll notice, does a great job of highlighting the incredible detail that went into the bike’s 3d printed components (if not a great job of highlighting how awesome the bike is to ride).

As a bike, 3d printer or otherwise, Ralf’s creation ticks all the right boxes. It uses a titanium alloy in the printed bits, which are then glued to ultralight, dry-carbon tubes to finish off the structure. Lightweight wheels, a THM crankset, and a noiseless belt-drive the bike, called the VRZ 2, forward. All in, the VRZ weighs just 4.9 Kg, making it a serious contender on paper.

On the street? I’d probably stick with my Langster, honestly – but there’s no question Ralf’s 3d printed VRZ would win the unofficial “Whose bike is that? It’s awesome!” contest down at the Star Lounge, and that might be enough. Check out the VRZ 2’s photo gallery, below, and let us know what you think of the bike in the comments, at bottom. Enjoy!
