READ ME FIRST – Sprocket & Chain Compatibility

NuVinci Harmony is compatible with the following size steel sprockets that are flat on at least one side:

• 16 Tooth

• 17 Tooth

• 18 Tooth

• 19 Tooth

• 20 Tooth

NuVinci Harmony is compatible with 3/32” (2.3mm) chains and sprockets only.

• Do not use 1/8” (3.2mm) single speed chains or sprockets

READ ME FIRST – Compatibility

NuVinci Harmony is incompatible with belt drive systems due to clearance at the rear wheel

The Harmony Hub Interface is incompatible with all derailleur hangars

READ ME FIRST – Minimum Sprocket Ratios

Bosch GEN2 Frame Motor E-Bikes

READ ME FIRST – Encoder, Programming, Calibrating

The color-matched Harmony Encoder must be installed on the N360 CVP for Harmony to function

• Sample units may be pre-installed

A Harmony Programming tool is provided to customize Harmony to the bicycle being produced – if this is not used, settings may be inappropriate for the bicycle

Every installation on a bicycle requires an initial calibration – skipping this calibration will result in poor ride performance and consistency

Install the Harmony Hub Encoder

The Harmony system comes with a color-matched Hub Encoder

• Six magnets in the Hub Encoder provide bicycle speed

Harmony Hub Encoder must be installed before sprocket installation

• Sample units may come with Harmony Hub Encoder pre-installed

Align the Hub Encoder

• Locate the key on the N360 CVP RH Shield

• Align the keyway on the Hub Encoder with the RH Shield

Install the Harmony Hub Encoder (continued)

Installing the Hub Encoder

• With the key and keyway aligned, start at that location and press the Hub Encoder onto the RH Shield

• “Walk” the snap-fit around to the opposite side with continuous pressure

• The Hub Encoder should be tight and secure, with the Hub Encoder ending flush to the CVP

Sprocket Requirements

REMINDER:

NuVinci Harmony is compatible with the following steel sprockets that are flat on at least one side:

• 16 Tooth

• 17 Tooth

• 18 Tooth

• 19 Tooth

• 20 Tooth

Minimum Sprocket Ratio as shown in tables earlier in this presentation

NuVinci Harmony is incompatible with belt drive system

Installing the Sprocket

Hub Interface Orientation and Installation Angle

0°

20°

• Orient the Harmony hub

interface roughly parallel to

the chainstay

• Move the hub interface along

the dropout to ensure

clearance at different axle

positions.

The Harmony hub interface

has integrated sensors at the

inboard location shown (4).

• Ensure that the sensor

location (4) is within the chain

perimeter and will not contact

the chain

• When installing hub interface,

be sure not to catch the chain

on the sensor (4)

Installing the Hub Interface

The 2012 Model N360 has two

splines, the Shift Driver (3) and the

Spline Nut (2). For Harmony

installation, Shift Driver location is

unimportant (the Harmony system

determines the shift position during

the initial calibration).

Installing the Hub Interface

When the installation angle is

aligned, seat the hub interface fully

onto the shift driver and the spline

nut until it is flush with the spline

nut, as shown

• N360 cable shift hub interface

shown, but Harmony Hub

Interface installation is identical

NOTE:

N360 cable shift hub interface shown here for reference only, but the Harmony Hub Interface installation process is identical

RH Nut serrations must face outward:

Fitting the Rear Wheel

Mount the Base Controller either on the left or right-hand side

Use the appropriate size O-ring and spacer for your handlebar size / location

Guide the cable and Base Controller connector to the bottom bracket location of the bicycle

• Be sure to provide excess cable for turning of the handlebars

Inspect all cables prior to installation - do not install if damaged.

OEM / assembler is responsible for routing cables in a way that will avoid damage with use.

Inspect all cables prior to installation - do not install if damaged

• OEM / assembler is responsible for routing cables in a way that will avoid damage with use

OEM must connect Harmony system to 18 - 44V (nominal) power source

• Maximum voltage the Harmony system can withstand is 50V peak

– Please check your battery chemistry to determine if the maximum voltage when fully charged is higher than 50V

– Higher voltage battery systems can be used, but must regulate voltage to the Harmony system to less than 50V peak

• When Harmony is powered by a source that cannot be switched on/off, Harmony can be configured to enter an ultra-low power “sleep mode”

– Panasonic System Example

▪ Spade-style connectors under battery connector are accessible

▪ Power source cannot be switched on/off when battery is installed

• When Harmony is powered by a source that is switched on/off with use, Harmony will automatically function

– Bosch System Example

▪ Bosch / Harmony wire harness is purchased from Bosch

▪ Power source automatically turns off

Once all wires are routed, connect them and apply power to the e-Bike & Harmony system

• Regardless of any indications, the Harmony system must be calibrated prior to use (see following pages)

E-Bike Electrical Integration (continued)

Calibration (REQUIRED prior to operation!)

Pedal the bicycle lightly and quickly through entire calibration procedure (preferably on a stand with rear wheel off the ground)

Initiate the Calibration Routine:

Continue pedaling lightly and quickly while the system shifts from “low” to “high” ratio multiple times and completes calibration

• Advanced Controller: Hold down the ‘Mode” Button until the rear hub begins shifting (5-7 seconds typically), then release the button

• Base Controller: Press and hold the Top and Bottom buttons simultaneously until the rear hub begins shifting (5-7 seconds typically), then release the buttons

Confirm Calibration & System Operation

Check system calibration

• Pedal the bicycle lightly and quickly while shifting through the ratio range (manual mode) and cadence range (automatic mode)

• Ensure the system is able to shift through the full range of the display without issue

• If operation is inconsistent while pedaling on a stand or riding, recalibrate the system

Reminders:

• Calibration:

– Without pedaling, Harmony will not calibrate correctly and function will be compromised

– Pedaling will get harder and easier during calibration as the Harmony system determines the shift range for the N360 CVP

– Pedal by hand lightly and quickly until the system stops shifting (less than 10 seconds)

• System Operation:

– The Harmony system will not shift if there is no pedal or wheel movement on the bicycle

– The ability to shift the N360 CVP is affected by input torque, and shifting can be delayed under high pedal torque and e-Bike assist levels

Appendix files

Low Cadence

• Very low cadence settings may have the following disadvantages:

– Very low cadence typically means high torque from the rider, which may compromise e-Bike battery range

– Very low cadence will shift through the ratio range of the N360 CVP more quickly, meaning cadence will increase once CVP is in full overdrive

High Cadence

• Very high cadence settings may have the following disadvantages:

– Some riders may not be able to pedal at very high cadences, and drivetrain will feel as if it “never shifts” because they don’t reach the cadence set point

– Some e-Bikes do not assist at higher cadence settings, so riders may be frustrated at a lack of assist from their e-Bike at higher cadence settings

Harmony Programming Tips

Cadence range

• Recommended to have at least 20 RPM difference between High and Low Cadence Settings

– Riders want to feel a cadence change, and less sensitive riders may not feel enough variation if the range is less than 20 RPM

– The smaller the cadence range, the more likely a rider will not be able to choose a comfortable cadence

Base Controller Recommended Settings

• High Cadence Setting: 70 RPM*

• Medium Cadence Setting: 55 RPM

• Low Cadence Setting: 40 RPM

Advanced Controller Recommended Settings

• High Cadence Limit: 85 RPM*

• Low Cadence Limit: 40 RPM

Harmony Programming Tips

* Some e-Bike systems do

not assist above 65 RPM -

plan High Cadence Setting

appropriately
