The patented NuVinci technology developed by Fallbrook Technologie is the most practical, economical and universally adaptable continuously variable planetary (CVP) transmission for human-powered machines.
The NuVinci transmission uses a set of rotating and tilting balls positioned between the input and output components of a transmission that tilt to vary the speed of the transmission.
Tilting the balls changes their contact diameters and varies the speed ratio. As a result, the NuVinci CVP offers seamless and continuous transition to any ratio within its range, thus maximizing overall powertrain efficiency, with no jarring or shocks from the shifting process, and improving acceleration, performance and overall vehicle efficiency over conventional transmissions.
When compared to traditional continuously variable transmissions (CVTs), the NuVinci CVP is less complex, has considerably fewer parts.
There is a clear distinction between Fallbrook's NuVinci continuously variable planetary (CVP) drive and more traditional continuously variable transmission (CVT) technologies. A CVT is a transmission that is infinitely variable between its high and low range as opposed to a conventional geared transmission where the number of speed ratios between high and low is limited by the number of gears.
The CVT has been called the "holy grail" of transmissions because it eliminates the multiple gears, shifting clutch and many other parts found in conventional transmissions. In place of gears, most CVTs use one or more cones, discs, balls, belts, toroids or other shaped devices for gradually changing ratios. These geometric shapes allow the input or output contact points on any particular device to vary in diameter, thus changing the input to output speed.
Were $650, now only $500
We have one fitted to a demo bike, feel free to book a test ride.
Ratio Range: 3.5:1, 250% (0.5 underdrive to 1.75 overdrive)
this is often referred to as a 350% range, but since a 2:1 is a 100% gear range and 3:1 is a 200% gear range, well, you get the picture
