Need help?Do you have a question about the TQ-Systems HPR50 and is the answer not in the manual?
The TQ HPR50 Drive Unit is an e-bike component designed to provide power assistance to the rider. It is intended exclusively for this purpose, and any other use is considered improper, voiding the warranty and absolving TQ-Systems GmbH of liability for damages. Proper transport, storage, installation, and operation are crucial for faultless and safe performance.
The manual emphasizes several safety precautions. Before performing any work on the e-bike, such as cleaning or chain maintenance, the HPR50 drive system must be switched off at the display, and the display must disappear. Failure to do so risks uncontrolled startup of the Drive Unit, potentially causing serious injuries like crushing, pinching, or shearing of hands. All repair, assembly, service, and maintenance work must be carried out exclusively by a TQ-authorized bicycle dealer.
Users are warned against making any changes to the Drive Unit that affect its performance or maximum supported speed, as this endangers the user and others, may violate laws, and voids the warranty. The walk assist feature should only be used to push the e-bike, ensuring both wheels remain on the ground to prevent injury. When walk assist is active, legs must be kept at a safe distance from the pedals to avoid injury from rotation.
The Drive Unit can become hot during operation due to load and other factors, potentially causing burns if touched with hands or legs during or after a ride. The housing of the Drive Unit must not be opened, as this voids the warranty. Removal and installation of the Drive Unit should only be performed by an authorized workshop.
For riding safety, users are advised to wear a suitable helmet and protective clothing and to observe local regulations. The high torque of the drive when starting up should be considered, and a suitable gear ratio or pedal assistance should be selected to prevent wheelies or rollovers. New users should practice handling the e-bike and its functions without assistance from the Drive Unit, gradually increasing the assistance mode.
The HPR50 drive system assists the rider up to a legally permitted speed limit, which varies by country. Assistance is provided only when the rider pedals. Above the speed limit, assistance ceases until the speed returns to the permitted range. The level of assistance depends on the selected assistance mode and the force exerted by the rider on the pedals; greater force results in greater Drive Unit assistance. The e-bike can also be ridden without Drive Unit assistance if the system is switched off or the battery is empty.
Before operation, ensure the battery is sufficiently charged.
The e-bike's speed is measured by a magnet (item 2) triggering pulses at the speed sensor (item 1). The sensor and magnet are factory-mounted with a distance of 1 mm to 8 mm in the rear wheel area. If the speed display shows incorrect values or fails, check this distance. During rear wheel installation, ensure the sensor or its bracket is not damaged. All related work should be done by a TQ-authorized bicycle dealer. Keep the speed sensor and magnet free of dirt to prevent signal interference.
Gear shifting on an e-bike with the HPR50 Drive Unit follows the same principles and recommendations as shifting gears on a bicycle without drive assistance.
The possible range on a single battery charge is influenced by several factors:
The HPR50 drive system components should only be cleaned with water from a standard household hose, not a high-pressure cleaner. Before cleaning, switch off the drive system at the display. Remove the optional Range Extender if necessary. Ensure the charging port cover on the bike frame is closed and engaged. After cleaning, check that the charging port is dry; water drops on contacts may prevent the e-bike from switching on.
All service, repair, or maintenance work must be performed by a TQ-authorized bicycle dealer. The dealer can also assist with questions regarding bicycle use, service, repair, or maintenance.
Observe permissible operating temperatures (-10 °C to +40 °C / 14 °F to 104 °F) and storage temperatures (-20 °C to +60 °C / -4 °F to 140 °F) during transport and storage. Adhere to country-specific regulations for transporting e-bikes and batteries. There is a risk of fire or electric shock from damaged batteries or range extenders, and unintentional startup of the HPR50 drive system during transport. Rechargeable batteries can be damaged by shocks or impacts. Take necessary precautions to prevent battery damage or accidental system startup.
Drive system components and batteries must not be disposed of in residual waste.
