Basically the N380 is capable of taking more power, for example an e-bike with a 350Watt motor. As you know here in the UK the maximum permitted motor power at the present time is 250Watts.

The Automatic Ride Experience

The NuVinci continuously variable bicycle transmission itself provides a unique riding experience. The addition of intelligent shifting has introduced a new era of cycling, the next revolution of shifting, which is truly automatic without any limiting or jarring steps. Harmony™ and Harmony H|Sync™ deliver simple and smooth automatic operation for an incomparable ride quality, optimize motor and battery performance and extend vehicle range.To benefit from the automation, the cyclist selects the desired cadence setting on a user interface and then simply pedals. The system monitors pedal and bike speed and continuously adjusts the ratios to maintain the desired cadence throughout the ride. On traditional pedal bikes, many cyclists may not be able to find the "right" ratio easily and eBike riders may shorten their range by not shifting effectively or not shifting at all. With intelligent automatic shifting the cyclist can forget shifting and enjoy cycling with Harmony and HarmonyTM H|Sync!

The Harmony hub interface and a Harmony controller turn the continuous shifting NuVinci drivetrain into a fully automatic gear box for your eBike. The Harmony intelligent drivetrain is the first continuously variable shifting system, and the only electronic shifting product for eBikes that gives you the option to seamlessly shift automatically or manually. The Advanced Controller is shown on the left with the blue face indicating automatic mode. It also has a manual mode in which the face is orange.

For the cyclist who simply wants auto-shifting, the Harmony Base Controller option keeps it simple with a three-button, auto-only model. Three preset cadence settings (slow, medium and fast) make auto-shifting as simple as: select a cadence, push a button and go. You'll get the same smooth, auto-shifting experience as the Advanced Controller model.

NuVinci CVTHarmony H|Sync offers continuous and automatic shifting fully integrated with the eBike user interface. Harmony H|Sync, based on the open CAN bus communication standard, provides eBike manufacturers with the opportunity to offer the unique continuous automatic shifting experience of Harmony, but without requiring an additional controller on the handlebar.

With Harmony H|Sync, the shifting action can be integrated directly into the eBike drivetrain user interface and will enable the addition of other experience-enhancing functionality. Working together with the NuVinci transmission technology, Harmony H|Sync offers a unique combination of electronic, automatic, and continuous shifting technology as a function of cadence. This creates the most user-friendly and efficient eBike drivetrain in the market - with almost every engine. And as with Harmony, manual gear shifting is available as an option.

Harmony H|Sync is a "platform" product and is initially introduced in conjunction with Bosch and the following eBike manufacturers who will offer the technology on model year 2015 eBikes in Europe: Merida, Centurion, Pegasus, Hercules, Zemo, Sparta, Sinus, Felt, Riese & Müller, Trek, Cube, KTM and Royal Dutch.

How it works.


With the Harmony Advanced Controller model, the cyclist selects and fine-tunes a cadence set-point by twisting the shifter until the blue RPM display indicates the desired setting. With the Harmony Base Controller, the rider chooses one of three factory preset cadence speeds and activates the system by simply pushing a button on the controller.

As the rider pedals, the weather-sealed Harmony hub interface monitors pedal cadence, senses vehicle speed and automatically adjusts ratio in the hub to maintain the set cadence as terrain and conditions change.

The Harmony Advanced Controller also offers the cyclist the option to shift manually and directly manage the continuously variable ratio range (orange display mode). Ratio changes are made simply by twisting the grip on the controller.

The pedal cadence pre-selection (e.g. 30-80 rpm) will take place via the controller of the motor and will be displayed in an individual menu item of the user interface. Once set, the Harmony H|Sync system will automatically maintain the selected cadence independent of the motor, the input power from the cyclist, and the topography of the route. At a stop, the system will automatically choose a proper ratio for subsequenteasy and energy-saving acceleration.

We test ride all Silver E Riders electric bikes before offering them to the general public for sale and I have to say the Nuvinci continuously variable bicycle transmission was a pure pleasure to use. The ride was so easy as the Nuvinci drive system was always in the right gear. Even is you are sat at traffic lights and want to change gear manually you can do it with ease and set off safely. I have tried it and think it is fantastic. Im sure when you come to test ride one of our bikes you will feel the same.
