The Orbit Drive promises an ebike transmission, built into the motor housing, that lasts for thousands of miles without maintenance, boosts efficiency and range, allows regenerative braking, and comes out lighter than most ebike drive systems.Continue … Continue reading Continuously variable ebike transmission promises up to 20% more range
When the subject of CVTs or continuously variable transmissions comes up, the chances are that most readers will think of the various motor vehicles they’ve appeared in. Whether it’s a …read more Continue reading A CVT For Every Application
As we’ve learned from past experience, videos from [HowToLou] tend to be a bit controversial. His unique style of expedient engineering isn’t everyone’s cup of tea, especially when it’s combined …read more Continue reading Riding Mower CVT Upgrade Really Gets Things Moving
[James Bruton] is experimenting is a series of interesting mechanical mechanisms, the latest being a CVT transmission system which uses a tilting sphere to get a variable speed output from …read more Continue reading Ball CVT Drives Robot From A Constant Speed Motor
The first continuously variable transmission fitted to an automobile actually has its roots in the late 19th century, though the technology has only become popular in the last two decades or so. While a relatively complex technology in its modern …read more

Finnish company Revonte has given us a glimpse into the future of e-bikes with a new compact drive system that integrates a motor, automatic stepless transmission and a bunch of electronics into a single tight unit with open control software.Continue R… Continue reading Revonte’s powerful e-bike motor has a built-in stepless transmission
After a couple of millennia of fiddling with gears, you’d think there wouldn’t be much new ground to explore in the field of power transmission. And then you see something like an infinitely variable transmission built from nested pulleys, and you realize there’s always room for improvement.
The electric motors generally used in robotics can be extremely efficient, often topping 90% efficiency at high speed and low torque. Slap on a traditional fixed-ratio gearbox, or change the input speed, and efficiency is lost. An infinitely variable transmission, like [Alexander Kernbaum]’s cleverly named Inception Drive, allows the motor to stay at …read more
