General riding notes

Functionality of the drive system HPR50
The HPR50 drive system supports you when riding up to a speed limit permitted by law which may vary depending on your country. The precon-dition for Drive Unit assistance is that the rider pedals. At speeds above the permitted speed limit, the drive system turns off the assistance until the speed is back within the permitted range.
The assistance provided by the drive system depends firstly on the selected assistance mode and secondly on the force exerted by the rider on the pedals. The higher the force applied to the pedals the greater the Drive Unit assistance.
You can also ride the e-bike without Drive Unit assistance, e.g. when the drive system is switched off or the Battery is empty.

Gear shift
The same specifications and recommendations apply for shifting gears on an e-bike as for shifting gears on a bicycle without Drive Unit assistance.

Riding range
The possible range with one Battery charge is influenced by various factors, for example:

• Weight of e-bike, rider and baggage
• Selected assist mode
• Speed
• Route profile
• Selected gear
• Age and state of charge of the Battery
• Tire pressure
• Wind
• Outside temperature

The range of the e-bike can be extended with the optional range extende.

Transport and Storage

• Observe the permissible operating temperature (-10 °C to +40 °C / 14 °F to 104 °F) and storage temperature (-20 °C to +60 °C / -4 °F to 140 °F) during transport and storage.
• Observe the country-specific regulations for the transport of e-bikes and batteries.

WARNING

Fire or electric shock hazard due to damaged Battery or Range Extender and unintentional start-up of the HPR50 drive system
The rechargeable batteries can be damaged by shocks or impacts during transport. Furthermore, the HPR50 drive system can be started up uninten- tionally.

• Take the necessary precautions to prevent the batteries from being damaged or the drive system from starting up.

Cleaning

• The components of the HPR50 drive system must only be cleaned with water from a standard household water hose and not with any high-pres-sure cleaner.
• Before cleaning switch off the drive system on the Display.
• Before Cleaning remove the optional Range Extender if necessary.
• Before cleaning the e-bike check that the cover of the charging port in the bike frame is closed and engaged.
