Even though almost all new mountain bikes now have just one chainring and no front derailleur, it would still be nice to have all those other gear ratios again. The Binary Gear is designed to bring them back, without reintroducing a front derailleur.Co… Continue reading Binary Gear doubles an MTB’s gear ratios, without a front derailleur

While bicycle gearboxes date back to at least the 1920s, they’re relatively unseen in bike racing. One exception is Honda’s race-winning mid-drive gearboxes, and [Alee Denham] gives us a look …read more Continue reading A Look Inside Bicycle Gearboxes
You can buy gears off the shelf, of course, and get accurately machined parts exactly to your chosen specification. However, there’s something rugged and individualist about producing your own rotating components. …read more Continue reading Cut Your Own Gears With This DIY Machine
Any project that contains something called a “flux modulator” instantly commands our attention. And while we’re pretty sure that [Retsetman] didn’t invent it after hitting his head on the toilet, …read more Continue reading Magnetic Gearbox Design Improvements Are Toothless but Still Cool
3D printers are good for a lot of things, but making parts for power transmission doesn’t seem to be one of them. Oh sure, some light-duty gears and timing belt …read more Continue reading 3D Printed Strain-Wave Gearbox Turns Up the Torque
Affordable brushless motors are great for a variety of motion applications, but often require a gearbox to tame their speed. [Michael Rechtin] decided to try his hand at designing a …read more Continue reading Stackable 3D-Printed Gearbox For Brushless Motor
A press is a useful thing to have, whether you like destroying stuff or you simply want to properly install some bearings. [Retsetman] decided to build one from scratch, eschewing …read more Continue reading 3D-Printed Gear Press Can Squash Stuff, Kinda
What do you do when you buy a broken shredder and, upon disassembly, find its gears in pieces? You might reach towards your 3D printer – this one’s not that …read more Continue reading Shredder Rebuilt From The Ashes, Aims To Produce More Ashes
While wheels might seem like a foundational technology, they do have one major flaw: they typically need maintained roads in order to work. Anyone who has experience driving a Jeep …read more Continue reading Tracked RC Vehicle is (Mostly) 3D Printed
