9.2 Replacement of parts
Not all components of your e-bike might be changed or replaced without approval. The two German associations
“
Zweirad Industrie Verband” (ZIV) and “Verbund Service und Fahrrad“ (VSF) have agreed on a uniform guideline. This
guideline defines the conditions under which e-bike components may be replaced. The document divides the e-bike
components into four different categories:
Category 1: Components which can only be replaced after approval by the electronic drive system provider or ROSE Bikes
• Motor
• Sensors
• Electronic control unit
• Electronic cables
• Control unit on handlebar/display
• Battery pack/charger
Category 2: Components which can only be replaced after approval by ROSE Bikes
• Frame
• Rear shock
• Rigid or suspension fork
• Brake system
• Pannier rack (racks directly affect the load distribution on a bicycle. Both negative and positive changes result in a
different road behaviour than the one originally intended by the manufacturer.)
Category 3: Components which can only be replaced after approval by ROSE Bikes or the component manufacturer
• Crank (provided that the distance between crank – centre of the frame (Q factor) is observed)
• Wheel (provided that the ETRTO is observed)
• Chain/belt (provided that the original width is observed)
• Rim tape (rim tape and rim must be compatible with each other. Modified combinations may result in rim tape
shifting and thus in defective inner tubes.)
• Tyres (stronger acceleration, additional weight and more dynamic cornering require the use of tyres approved for
e-bike use. It is important to observe the ETRTO.)
• Brake cables/brake hoses
• Brake pads
• Handlebar and stem (provided that there is no need to change the length of cables and/or hoses.)
• Saddle and seat post (provided that the offset to the rear does not exceed 20 mm compared to the original saddle/
seat post combination. A modified load distribution beyond the intended adjustment range may possibly lead to
critical steering properties. The length of the saddle rails and the shape of the saddle are also important.)
• Headlight (headlights are designed for a specific voltage which must be compatible with the battery pack of the
respective e-bike. In addition, the electromagnetic compatibility (EMC) must be guaranteed, whereas the headlight
may be responsible for a part of the potential disturbance.)
Category 4: Components which can be replaced without approval
• Headset
• Bottom bracket
• Pedals (provided that the pedals are not wider than the series/original pedals)
• Front and rear derailleur (all shifting components must be suitable with the number of gears and compatible with
each other)
• Shifter/twist shifter
• Shift cables and housings
• Chainrings/cassette (provided that number of teeth and diameter are identical to the original)
• Spokes
• Inner tube (with identical design and identical valve)
• Rear light, reflector, spoke reflectors
• Kickstand
• Grips with bolt-on clamp
• Bell
