Wheel Kit: Nuvinci CVP Hub
Everything you need to upgrade your trike with the new Nuvinvi N360 CVP Hub. This kit features the Nuvinci CVP Hub, custom 20-inch or 26-inch wheel, spokes, nipples, Schwalbe liner, shifter, and cables. If you add a tire and tube to your order we will install them at no additional charge. We recommend this upgrade be used together with the Schlumpf High Speed Drive, or a single chainring in the front end. If you will be using the this wheel with a triple chainring setup, you will need to be creative. Most derailleur-style chain tensioners will not fit on the trike with the Nuvinci hub because of the shifter housing. We recommend using a single chainring or a Shlumpf HSD 34/85. The best chain tensioners that we have found to work with the Nuvinci are the YESS tensioners. Installation is free for local customers. NuVinci Continuously Variable Planetary Hubs. Simple twist control for smooth, progressive shifting without Simple twist controller enables easy, continuous ratio adjustments while pedaling, coasting or at a stop. No missed gears, hesitation or noise Includes CruiseController shifter and 17t freewheel Why the NuVinci hub? The NuVinci continuously variable planetary (CVP) is the first viable CVT drivetrain for trikes and a revolutionary, new alternative to conventional derailleur and fixed-gear internal hubs delivering a totally unique riding experience. The ride is incredibly smooth, allowing the rider to shift "gears" while pedaling, coasting, or at a standstill. Its elegant, simple design delivers all the advantages of planetary gear sets without the limitation of fixed speed ratios, without wide gaps between gears, and without jolts or jerks to the rider's legs and lower back. Compared to the original NuVinci trike drivetrain, the N360 model is over 30% lighter, 17% smaller and has an increased ratio range. Shift effort is significantly reduced even under high pedal forces and there is 50% less twist rotation required to move between the lowest and highest ratios. In addition, for better protection, the hub interface is now housed inboard of the frame drop-out. With an infinite number of ratios available within its nominal 360% ratio range, the N360 drivetrain is an attractive replacement for derailleurs and internally geared hubs as it provides a ride and shifting experience unlike any other. The NuVinci CVP enables riders to maintain an optimum cadence regardless of terrain and makes shifting as easy as adjusting the volume on a radio Ideal for cruiser and commuter riding styles, the NuVinci CVP offers a smooth adjusting ratio range. The CVP offers the smoothest and quietest ride. There's no hesitation, no noise, no waiting for the mechanism to "hunt" for the selected gear, nothing to synchronize, and nothing to guess at. A simple twist of the wrist and the NuVinci CVP seamlessly and progressively adjusts to a new ratio. Gone are the intimidation and complexities of conventional shifting, missed gears and dropped chains. The NuVinci CVP is compact, dependable and completely sealed for protection from weather, dirt, and abuse. The NuVinci CVP is revolutionizing the bicycle rider experience with features like: • No gears to fear • Best, smoothest-adjusting-ratio hub ever produced • Uses a set of rotating spheres to transfer torque from pedals to the road • Effortlessly glides between an infinite number of ratios • Simple twist control for smooth, easy progressive changes in ratio • Change ratios any time, even while stopped or going uphill • No missed gears, jerks, thumps, hesitations or noise • Dependable, performance unaffected by weather, dirt or mud Nuvinci FAQs
Why is the technology named NuVinci? The name represents a "tip of the hat" to Leonardo da Vinci who, over 500 years ago, sketched what is considered to be the first documented continuously variable transmission. How does the NuVinci CVP work? The NuVinci transmission uses a set of rotating balls between the input and output components of a transmission that tilt and vary the output speed of the transmission. Tilting the balls changes their contact diameters with the discs, which varies speed. As a result, the NuVinci CVP improves acceleration, performance and powertrain efficiency over conventional transmissions. It is far simpler, permits more stable control, is better packaged, provides more scalability across product lines, is better packaged, and is less expensive to manufacture and assemble than traditional CVTs. CVTs have been around for a long time. Why have they not become commonplace? The use of CVTs has not become widespread due to multiple problems including scalability challenges, questionable reliability and durability, high cost, and other factors. Despite some obvious drawbacks, some manufacturers such as Ford, Nissan, Honda, and Audi have implemented limited production with old CVT technology because the market need was so great. However, with the development of the NuVinci CVP, the technical roadblocks now have been eliminated – clearing the way for a wide range of CVP applications for which markets are ready and waiting. How is the NuVinci CVP different from conventional transmissions? The NuVinci CVP offers a wide range of advantages over conventional transmissions. These advantages include: • Less complexity • Greater powertrain system efficiency • Greater acceleration and optimum performance • Easier shifting • Ability to accept multiple inputs while varying speed and managing torque • Multiple power outlets such as for a power take off (PTO) application • Easier to package and potentially lighter • Easier and less costly to manufacture • Greater scalability and potential to reuse tooling • Improved hill-climbing How is a NuVinci CVP different from other approaches to CVT technology? There are four widely accepted alternative approaches to CVT technology: Toroidal The NuVinci CVP, comparatively, offers better torque capacity and simpler control, and is more easily packaged for inclusion in a given application due to its concentric input and output shafts. It is also much more effective to scale across a vehicle range because of its modular nature, and is more durable because of its greater number of traction contacts. Push Belt The NuVinci CVP is simpler in design, more scalable, easier to control, allows for inline shifts, and is less expensive to manufacture. It also does not have the ultimate torque capacity limitations of the push belt and is expected to be more durable. Hydromechanical The NuVinci CVP is much easier to manufacture, easier to control, is lighter, more scalable, inherently quieter, and easier to maintain. Chain The NuVinci CVP has greater torque capacity, allows for inline shafts, is lighter, more scalable, inherently quieter, and less expensive to manufacture and maintain. How does NuVinci N360 hub impact my riding experience? The short answer: It is unlike anything you have experienced before. You'll find yourself shifting without thought, whenever you feel like it - while you're pedaling, when you're coasting (freewheeling), when you're pedaling backwards, even when you're stopped. There's no hesitation, no noise, no waiting for the mechanism to "hunt" for the gear you've selected, nothing to synchronize, nothing to guess at, a simple twist of your wrist and you're at a new ratio. Say goodbye to racking your shins and dropped chains due to derailleur mis-shifting. You'll easily find your sweet-spot, adjust your cadence for max power, or up-shift at will to work your legs a bit more. With the NuVinci hub, you're easily in charge of your riding experience. What are people saying about hubs with NuVinci technology? Reaction to the NuVinci CVP hub has been nothing short of phenomenal. Bicycle industry executives and consumers alike are quoted as saying: "Smooth", "very smooth" "very smooth, unbelievable", "silky" "It's so easy to shift and maintain a perfect cadence." "Takes the worry out of shifting" "I haven't missed riding a bike until now" "It is the best transmission on a bicycle" "I have seen nothing like it" "[this] technology is a great fit..." "The ride quality is ready now!" "I want it now!" Is there any required maintenance? The hub contains a "traction" fluid. The only recommended maintenance is that the fluid be changed periodically. The change interval will be determined by the manufacturer and type of use but is expected to be every 24 months. Also, unlike bikes with a sensitive derailleur, all of the component parts are enclosed within the hub making it less likely that a part could be hit and damaged, as well as minimizing the exposure of moving parts to dirt and debris. What is the ratio range and efficiency of the NuVinci CVP hub? From bench and road testing by potential consumers and industry experts, the NuVinci CVP compares favorably with the internally geared hubs on the market today and has the same or better ratio range. How much does the NuVinci CVP Hub weigh? Our first model is designed for cruiser/comfort and commuter trikes. The weight of the NuVinci rear hub is greater than that of a rear derailleur drivetrain. However, multiple chain rings, a cassette and dual shifters are no longer required.
Share your comments below: Hello. Is there any way I can order this hub with a 26" wheel Posted by Tim 02/21/2010 08:56:58 AM Yes, it is the same price. WILL THE NUVINCI HUB FIT MY SUN X-3 USX? Posted by HANK 03/12/2010 10:46:01 AM No. The flange is too wide to fit a drive sprocket that would go to the rear axle. What's the gear range on this hub? Posted by Patrick 04/17/2010 03:12:40 AM 350% range. Which version of the Nuvince hub is used in these wheels? Posted by skullpin 05/13/2010 10:07:46 PM When the n360 version is available we will offer that. For now it is the original freewheeled version. I have a greenspeed GT3 folding trike with 16" wheels. Will this hub work with this trike? Posted by Rick 06/08/2010 03:54:39 PM I recommend waiting for the N360 version which can be laced to a 16 inch wheel. Do you have N360 in stock? Can they be put on the TerraTrike Path 8 DL and for how much? Does the N360 work with the Schlumps High Speed Drive or is it overkill to do that? Thank you. Posted by JJR 07/02/2010 08:45:01 AM The N360 will be availble in late August. Is this the latest version of the Nuvinci, the 360? Posted by byt0saur 07/12/2010 01:14:25 PM The N360 will not be available until late August. At that time we will have a new product page set up.
