Category 3 *
Parts which may be replaced upon approval of the vehicle or
component manufacturer
• Crank arm
(Provided that the distances crank arm – frame
centre (Q-Factor) are observed)
• Wheel without hub motor
(Provided that the ETRTO is observed)
• Chain / Toothed belt
(Provided that the original width is observed)
• Rim tape
(Rim tapes and rims must be compatible.
Modied combinations may result in rim tape
shifting and thus in defective inner tubes)
• Tires
(The stronger acceleration, the additional
weight and more dynamic cornering require
the use of tires approved for e-bike use. In this
respect, observance of the ETRTO is essen-
tial)
• Brake cables / Brake hoses
• Brake pads
(Disc, roller, drum brakes)
• Handlebar-stem unit
(Provided that there is no need to change the
lengths of cables and/or hoses. A modica-
tion of the seating position for the benet of
the consumer should be possible within the
original cable lengths. A modication beyond
results in a signicantly changed load distribu-
tion on the bicycle and entails potentially criti-
cal steering properties)
• Saddle and seat post unit
(Provided that the offset to the rear does not
exceed 20 mm with regard to the series/ origi-
nal eld of use. In this case, as well, a modied
load distribution beyond the intended setting
range may possibly lead to critical steering
properties. The length of the saddle rails at the
saddle structure as well as the saddle form are
also important)
• Headlights
(Headlights are designed for a specic voltage
which must be compatible with the rechargeable
batteries of the vehicles. In addition, the electro-
magnetic compatibility (EMC) must be ensured
whereas the headlight may be responsible for a
part of the potential disturbance)
Category 4
Components which do not require a specic approval
• Headset
• Bottom bracket
• Pedals
(Provided that the pedal is not wider than the
series/ original pedal)
• Front derailleur
• Rear derailleur
(Provided that the number of teeth and the di-
ameter is identical to the series/original eld
of use)
• Shift levers / Twist grip
• Cables and housings
• Chainwheels / Belt sprockets / Cassette
sprocket
(Provided that the width is not smaller than the
series/ original parts and the clearance to the
tire is 10 mm at least)
• Kettenschutz
• Radschützer
(Wenn die Breite nicht kleiner als die Se-
rien- / Originalteile sind und der Abstand zum
Reifen min. 10 mm beträgt)
• Spokes
• Inner tube with identical design and iden-
tical valve
• Dynamo
• Rear lamp
• Reector
• Spoke reector
• Kickstand
• Grips with screw clamps
• Belle

* An approval can only be given by the component manufactur-
er, if the component was sufciently tested in accordance with its
intended use and the respective standards and if a risk analysis
was made in advance.
This is the translation of the original guidelines issued by ZIV,
VSF and BIV (German umbrella organisation for the German
cycle industry guilds) in cooperation with Zedler-Institut, updated
in 2017. In the event of any misunderstandings, the
original German version (Leitfaden für den Bauteiletausch bei
CE-gekennzeichneten E-Bikes / Pedelecs mit einer Tretunter-
stützung bis 25 km/h) shall be applicable.
Please take note that you may only ex-
change certain parts of the S-Pedelec
against parts of another type. Your
registration will otherwise become invalid and
the insurance protection will no longer apply.
