USER MANUAL PW45 YAMAHA

Model overview and max. permissible total weight for model year 2016

Definition

The max. permissible total weight consists of the maximum weight of the vehicle, rider and load.

Pedelec: Pedal electric cycle

EPAC: Electrically power assisted cycles

XII - English English - XIII

Speed Pedelec (short S-Pedelec) or Speed EPAC:

Pedelec: Pedal electric cycle

EPAC: Electrically power assisted cycles

Both terms mean a bicycle with electrical power assist, which only supports the rider when pedalling. The assistance stops at 25 km/h. A EPAC resp. pedelec is classified as bicycle according to traffic law.

Speed: The prefix, Speed* signalizes that the EPAC / Pedelec assists up to a speed of 45 km/h. Also an only electric use up to 20 km/h is possible. Please see below for traffic law information for Speed EPAC.

You can find an overview of the specific regulations in the respective countries in chapter „Country specific rules“.

Present situation: March 2016

Please note that the legal information in this overview may lose its topicality.

Please further note that different regulations may partly apply in different countries. Please read chapter for „country specific rules“.

The following instructions do not claim to legal correctness, errors excepted.

Difference between a „normal“ Pedelec / Bicycle and a S-Pedelec

Please note that your S-Pedelec is a motor vehicle class L1e and not a pedelec / bicycle, with all resulting consequences regarding traffic law, insurance law, authorisation requirement if necessary, criminal law.

Liability insurance

It is mandatory to be in possession of a moped liability insurance in order to drive a S-Pedelec on public means. Applicable insurances you can receive from insurances or also banks.

Insurance tag

You will receive an insurance tag from your insurer. It has to be mounted on the license plate holder of the S-Pedelec. If there is an obligation to authorize the S-Pedelec in a country, you have to mount a license plate instead of the insurance tag.

Authorisation requirement & license plate

Some countries might have an authorisation requirement and thus requires a license plate (comparable with a motorcycle). Please read the chapler „country specific rules“

CoC document / EG declaration of compliance

CoC = Certificale of Conformity

This document is enclosed to your S-Pedelec and clearly assigned to this vehicle. The CoC confirms that the vehicle corresponds to the authorised type. You need the CoC documents to insure your vehicle. Furthermore you have to carry the CoC documents with you while using the S-Pedelec.

Please note:

Keep the CoC stored securely. You need this to insure the vehicle. In case of a re-sale of the vehicle the buyer will ask for the CoC. A subsequent drafting of a CoC duplicate is associated with high effort and costs.

Non EU countries

In Non-EU countries it is not ensured that the provided EG declaration of compliance suffices. E.g. for Switzerland an own type authorisation and vehicle ID is required.

Classification of the S-Pedelec as motor assisted bicycle (moped)

According to the current, however, not undisputed legal opinion the S-Pedelecs are considered as motor assisted bicycle (moped). This classification is based on the view that the maximum design speed, which is a b.0. significant for the classification, is the speed you can reach only with the motor drive. This is for S-Pedelecs <20 km/h, nevertheless you can reach a speed of up to 45 km/h with pedaling assistance. Up until now the German Department of Motor Vehicles has this opinion and approves vehicles of this type with a maximum design speed of <20 km/h.

The S-Pedelecs of Winora-Staiger GmbH are all approved with a maximum design speed of <20 km/h. This is described in the certificale of conformity. (CoC)

Driver's license, cycle tracks, helmet compulsory

Transport of children / goods with a S-Pedelc of Winora Staiger GmbH

The transport of children or other goods in a trailer with a S-Pedeloc of Winora-Staiger GmbH is not allowed. Furthermore the transportation of children in a trailer in legally forbidden in Germany.

There is a possibility of transporting a child in a child seat, however, this is not allowed by Winora-Slaiger GmbH.

Winora-Staiger GmbH does not assume any liability for damages, resulting from the use of a trailer and/or child seat in combination with the S-Pedelec.

Minimum tread depth

Please note that for motor vehicles like the S-Pedelec a minimum tread depth of 1 mm is required.

The e-Bike Systems do not operate in the following situations:
- When the display unit's power is off.
- When you are moving 45 km/h or faster.
- When you are not pedaling.
- When there is no residual battery capacity.
- When the automatic power off function* is operating.
* Power turns off automatically when you do not use the e-Bike Systems for 5 minutes.
- When the assist mode is set to Off mode.
- When the running assist switch is released.
- When the display unit is removed.

Four types of "assist mode" + Off mode are available.

Choose from High-Performance mode, Standard mode, Eco mode, +Eco mode and Off mode to suit your riding conditions. See "Displaying and switching the assist mode" for information on switching between assist modes.

High-Performance modeUse when you want to ride more comfortably, such as when climbing a steep hill.

Do not dispose of the battery pack in a fire or expose it to a heat source. Doing so could cause fire, or explosion, resulting in serious injury or property damage.

Do not modify or disassemble the e-Bike Systems. Do not install anything other than genuine parts and accessories. Doing so could result in product damage, malfunction, or increase your risk of injury.

When stopped, be sure to apply the front and rear brakes and keep both feet on the ground. Placing one's foot on the pedals when stopped may unintentionally engage the power assist function, which could result in loss of control and serious injury.

Do not ride the bicycle if there is any irregularity with the battery pack or e-Bike Systems. Doing so could lead to loss of control and serious injury.

Be sure to check the residual battery capacity before riding at night. The headlight powered by the battery pack will turn off soon after the residual battery capacity has decreased to where power assisted riding is no longer possible. Riding without an operating headlight can increase your risk of injury.

Do not start off by running with one foot on a pedal and one foot on the ground and then mounting the bicycle after it has reached a certain speed. Doing so could result in loss of control or serious injury. Be sure to start riding only after you are seated properly on the bicycle seat.

Do not press the running assist switch if the rear tire is off the ground. Otherwise, the tire will turn at high speed in the air and you could be injured.

Do not remove the display while riding the bicycle. Doing so will turn off the power assist, and could result in the bicycle falling over.

text_image Battery capacity indicator Battery capacity indicator lamp YAMA Battery capacity indicator button Charging connector

The battery pack equipped for the Yamaha e-Bike Systems is a lithium-ion battery. The lithium-ion battery is lightweight and offers superior capacity. However, it does have the following characteristics.

  • Its performance decreases in extremely hot or cold environments.
    • It naturally loses its charge.
  • It is necessary to use it several times before its performance stabilizes.

The battery pack for the Yamaha e-Bike Systems also has an embedded computer which notifies you of estimated residual battery capacity and suspected faults via the battery capacity indicator lamp.

By pressing the battery capacity indicator button, you can display the residual battery capacity for approximately 5 seconds.

See "CHECKING THE RESIDUAL BATTERY CAPACITY" for the estimate of the residual battery capacity. See "TROUBLESHOOTING" for information on fault flashing.

BATTERY PACK AND CHARGING PROCEDURE

Appropriate charging environments

For safe and efficient charging, use the battery charger in a location that is:

  • Flat and stable (when on the bicycle)
    • Free of rain or moisture
    • Out of direct sunlight
    • Well-ventilated and dry
    • Not accessible to children or pets
    • Temperature between 15–25 °C

Inappropriate charging environments and solutions.

The hot and cold environments described below can cause charging to enter standby or suspension without fully charging the battery.

• Summertime charging standby/suspension

If charging in a location receiving direct summer sunlight or immediately after riding, the battery charger might enter charging standby (all four battery capacity indicator lamps flash slowly). See "Reading the charging status". This is to automatically stop charging in order to protect the battery from exceeding the specified temperature while charging. You can avoid charging suspension by starting to charge with the battery cold or at a room temperature of 15–25 °C. If charging suspension occurs, move the battery charger to a cool location to reduce the charging standby time.

• Wintertime charging standby/suspension

Charging standby will occur if the temperature is 0 °C lower. If charging is started and the temperature drops below this level due to late-night cooling or other factors, charging is suspended and standby mode is entered to protect the battery. In such cases, restart charging at an indoor location with a temperature of 15–25 °C.

- Noise on televisions/radios/computers

Charging next to televisions, radios, or similar appliances might cause static, flickering images, and other interference. If this occurs, recharge in a location further away from the television or radio (such as in another room).

BATTERY PACK AND CHARGING PROCEDURE

WARNING

If a charging fault occurs during charging, remove the power plug of the battery charger from the socket and wait for the battery pack/battery charger to cool.

YAMAHA PW45 - TIP - 1

text_image Charging start Charging finish Charging standby Charging time* (Not including standby time)

Charging time guidelines

Although charging time varies depending on residual battery capacity and external temperature, if the battery has been exhausted, it generally takes approximately 3.5 hours until one battery capacity indicator lamp flashes.

If the battery pack enters standby mode while charging, charging time will increase by an equal amount.

* If charging after a long period of disuse, the charging time will be lengthened depending on the battery status. However, note that if the battery capacity indicator lamps do not flash in fault pattern (See "Reading the charging status"), there is no malfunction.

CHECKING THE RESIDUAL BATTERY CAPACITY

You can check the estimate of how much capacity is left in the battery and to what extent it is charged. The check can be performed using either the display unit's residual battery capacity indicator or the battery's residual battery capacity indicator lamps.

TIP

  • Even if the battery's capacity reaches 0 (zero), you can still ride the bicycle as a regular bicycle.
  • If you are using an old battery pack, the residual battery capacity indicator may suddenly display very little power when you start moving. This is not a malfunction. Once riding stabilizes and the load is reduced, the proper value is displayed.
